“Weaker PCB”, but still (Gigabyte Aorus X670 Elite AX) stands out

Gigabyte Aorus X670 Elite AX in detail

Motherboards for the AMD AM5 platform with chipsets without “E” in the designation have weaker connectivity derived from the processor, but if you do not require PCIe 5.0 for the graphics card, you do not really need to worry. And not at all with the Aorus X670 Elite AX board, which defends the “Elite” label without the slightest difficulty. For proper features, but also for the fact that Gigabyte has once again pushed the performance more than usual.

Just like the last tested MSI MEG X670E Ace board, the Gigabyte Aorus X670 Elite AX, which we’ll take a look at now, is built on two Promontory chips (the ones the X670E and X670 boards have in common). The difference is that X670 boards do not support 16 PCIe 5.0 lanes for graphics card connections. This may stem from PCB design limitations, which on these boards may not be capable of such high speeds.

So X670 boards may be cheaper, but that still doesn’t make them second class. PCI Express 5.0 support is certainly a benefit, but it’s still a novel thing that current graphics cards don’t benefit from. Thus, some may consider it as a technology whose absence can be used to save a bit of money when buying a motherboard. Typically, users who don’t upgrade their build on an ongoing basis (those will miss PCIe 5.0 later on, after the release of the next generation of graphics cards), but will buy a whole new build when it comes down to it. This could make the Aorus X670 Elite AX make pretty good sense no matter what components they choose now.

Gigabyte Aorus X670 Elite AX

Categorically, the Aorus X670 Elite AX is between the X670 Gaming AX (Gigabyte’s cheapest board with the X670 chipset) and the X670 Aorus Master (Gigabyte’s second most expensive X670 board). Within Gigabyte X670 motherboards, we can thus speak of a mid-range motherboard, although from an overall perspective (when we also take into account the B650 models) it is an above-average equipped motherboard. Towards the top is the last one, where you don’t pay extra for the illuminated cover between the rear I/O panel and the VRM heatsink.

The board format is ATX (305 × 244 mm). Of the PCI Express slots, three are fitted – all long, physically ×16. However, only the first one, connected to the processor, has the full number of contacts to connect 16 PCIe lanes. The latter is in the fifth generation (of this interface) only partially. It doesn’t support PCIe 5.0×16 for graphics cards, as mentioned above, but it can handle four lanes for SSDs (which the processor has reserved). At the time of writing this article, although no SSDs with PCIe 5.0 support are sold, this board counts on them in the future.

   

It is possible to install 80 and 110 mm SSDs in all M.2 positions. For the smaller ones, there are no mounting holes on the PCB for the spacers. These (the spacers) have a rather original mounting mechanism with a flip lock. This is used to secure the SSD instead of a screw. However, it is not a more elegant mechanism than the spring-loaded one Gigabyte uses on some other boards (including the Z790 Aorus Elite AX).

The disadvantage of this solution is that the top of these locks sticks to the heatsink thermal pads. And if you don’t hit the threads the first time you mount the heatsink, and a correction is needed (by shifting), you’ll probably pull the SSD out of the slot as well. Unintentionally, of course. Both the lock and the SSD get glued to the cooler and there you go… Although it may seem like a small thing, installing an SSD can be quite complicated. Especially when you’re trying to do it in cramped conditions (which the case always creates to some extent) with the motherboard typically in a vertical position.

   

On the contrary, the demounting of the graphics card is quite convenient. Gigabyte has made a kind of an extension to the latch of the first PCI Express ×16 slot – a lever that is more offset from the card, closer to hand. This will be especially appreciated by owners of wide, dual-tower CPU coolers.

The power delivery around the LGA 1718 (AM5) socket is robust, consisting of up to 20 phases. Of these, 16 are for Vcore to power the processor. This part is completely managed by Infineon components – 16 TDA21472 voltage regulators controlled by the XDPE192C3B chip. The maximum current load per phase according to the specifications is 70 A. In other words, everything is well oversized even for the Ryzen 9 7950X, which with a PPT of 230 W is the most powerful processor that can currently be used on the AMD AM5 platform.

   

There are up to 13 USB ports on the rear I/O panel, most of them faster (6×3.2 gen. 1), fast (2×3.2 gen.2) and one very fast (3.2 gen 2×2 type-C). Audio connectors are in a set of three as is the case on the Z790 Aorus Elite AX board, but here there is a line input instead of an optical output (S/PDIF). The audio adapter configuration is poorer overall. Not only is the audio codec here “only” Realtek ALC897, but you also have to do without a more powerful headphone amplifier and better capacitors (WIMA, which some Gigabyte boards with ALC897 have). The isolation from the rest of the board is good though, electromagnetic noise doesn’t interfere significantly with the sound.

Interestingly, the WiFi 6E module (with BT 5.2) is just behind the SMA connectors for external antennas, which was not always the case. On older boards it often used to be in the middle as well, and the antennas used to stretch around the board for a longer route, which naturally caused more interference than when this module is completely on the edge of the board. It connects via an M.2 (E-key) connector, vertically.

Motherboards for the AMD AM5 platform with chipsets without “E” in the designation have weaker connectivity derived from the processor, but if you do not require PCIe 5.0 for the graphics card, you do not really need to worry. And not at all with the Aorus X670 Elite AX board, which defends the “Elite” label without the slightest difficulty. For proper features, but also for the fact that Gigabyte has once again pushed the performance more than usual.

What it looks like in BIOS

The UEFI graphical interface is clear and feature-packed. Many users will have no reason to go beyond “Easy Mode” (i.e. the splash screen). There, basic information about connected components (CPU, RAM, SSD, fans) is available, there is traditionally a button to activate AMD EXPO and AMD RAIDXpert2, for example, has its own switch.

Details about the components (or BIOS) beyond that are in extended mode on the System Info tab. From there you can also read that at the time of writing, the latest F7a BIOS still contains the AGESA 1.0.0.3 patch D microcode.

More detailed tuning is traditionally on the Tweaker tab. We do not interfere with these default settings for the purposes of motherboard tests, so that the tests reflect the “identity” of the board that users will usually encounter in practice.

   

Except for enabling the memory profile (AMD EXPO) we don’t change anything, everything is as the board “automatically” sets it. However, it should be noted here that with the activation of EXPO, the clock speed of the memory controller, UCLK (Uncore Clock), is increased beyond standard to 3000 MHz. On many other boards this does not happen and they operate with 1500 MHz. Because of this (mainly because of the lower RAM latency), a slightly higher performance, on the order of one percent, is often achieved compared to competing models. The clock speed of the Infinity Fabric (FCLK) remains already at the traditional 2000 MHz.

   

We don’t interfere with the LLC in the settings, but you can naturally adjust it. For lower performance settings, you need to go to the advanced PBO settings.

      

It’s perhaps a bit of a shame that Gigabyte doesn’t have some preset profiles to adjust the power limits at different levels, like MSI for example. However, you can always set the exact value manually, both for the power draw limit and current limits.

The Resizable BAR settings could also be closer to users, more in plain sight (for example, on the home screen in the form of a two-position toggle switch). These are nested in the advanced mode on the Settings tab. ReBAR is enabled by default, and admittedly the reasons to disable it are minimal. But there are still situations where it takes away performance rather than adding it. Especially in computing applications for which this “gaming” technology is not primarily optimized.

The fan management interface is as you know it on Gigabyte boards – top notch. There’s nothing missing from the features that you might need and all the options are easily accessible on one screen. There are five temperature sources that you can adjust according to, and this board has a PCIe ×16 slot sensor among them. This is heated by the graphics card, and according to its readings, it is possible to regulate the system fans typically according to the load of the graphics card.

If you do not want to manually set the PWM curves (depending on the temperature of the selected component, e.g. also the VRM), there are preset profiles Silent, Normal and Full Speed to choose from.

   

All connectors are sensitive, operating from very low PWM intensity. You can also set an alert for each of the connectors, which will inform you if the fan fails or stops. This can happen, especially when you try to optimize the operation of the fans with respect to the lowest possible speed.

Motherboards for the AMD AM5 platform with chipsets without “E” in the designation have weaker connectivity derived from the processor, but if you do not require PCIe 5.0 for the graphics card, you do not really need to worry. And not at all with the Aorus X670 Elite AX board, which defends the “Elite” label without the slightest difficulty. For proper features, but also for the fact that Gigabyte has once again pushed the performance more than usual.

Gaming tests…

The vast majority of tests is based on the methodology for processors and graphics cards. The choice of games is narrower with motherboards, but for this purpose there is no need for more of them. The processor we use is always the powerful AMD Ryzen 9 7950X or on Intel platforms It’s the Core i9-13900K. These processors highlight both the strengths and weaknesses of any motherboard well. In the past we have tested with two processors, including a cheaper, more low-power model, but we don’t do that anymore. The hypothesis that more expensive motherboards might give an “advantage” to cheaper processors in performance has not been confirmed, so it’s rather pointless.

We’ve selected five titles from games we’re testing in two resolutions. There are significantly fewer games than in the CPU or graphics card tests, but these are just enough for the motherboard tests. Few people consider performance in a particular game when choosing a motherboard. But an indicative overview of which motherboard shapes gaming performance in what way (compared to another motherboard) is necessary. To avoid significant discrepancies over time, we’ve reached for relatively older titles that no longer receive significant updates.

These are Borderlands 3, F1 2020, Metro Exodus, Shadow of the Tomb Raider and Total War Saga: Troy. With newer games, there might be some performance changes over time (updates) and especially in high resolutions with high details. This is one of the test setups (2160p and Ultra, or the highest visual detail but without ray-tracing graphics) that focuses on comparing performance, for which the bottleneck is the graphics card. In other words, it will be clear from these tests which motherboard can affect the performance of which graphics card to what extent for any reasons. In contrast, a setup with Full HD resolution and with graphical details reduced to “High” will also reflect the CPU’s contribution to the final gaming performance.

We use OCAT to record fps, or the times of individual frames, which are then used to calculate fps, and FLAT to analyze the CSV. The developer and author of articles (and videos) for the GPUreport.cz website is behind both.
For the highest accuracy, all runs are repeated three times and average values of average and minimum fps are displayed in the graphs. These multiple repetitions also apply to non-game tests.

… Computing tests, SSD tests, USB ports and network tests

We test application performance in a very similar way to the processor tests. Almost all tests are included, from the easier ones (such as those in a web environment) to those that push the CPU or graphics card to the limit. These are typically tests such as 3D rendering, video encoding (x264, x265, SVT-AV1) or other performance-intensive computing tasks. As with processors or graphics cards, we have a wide range of applications – users editing video (Adobe Premiere Pro, DaVinci Resolve Studio), graphic effects creators (Adobe Premiere Pro), graphic designers or photographers (Adobe Photoshop and Lightroom, Affinity Photo, AI applications Topaz Labs, …) will find their own in the results, and there are also tests of (de)encryption, (de)compression, numerical calculations, simulations and, of course, tests of memory.

SSD performance tests are also important for motherboards. Therefore we test the maximum sequential read and write speeds on an empty Samsung 980 Pro SSD (1 TB) in the well distributed CrystalDiskMark, in all slots. We approach the USB port tests in the same way. We use a WD Black P50 external SSD to test them. It supports fast USB 3.2 gen. 2×2, so it won’t be a bottleneck for even the fastest USB controllers. We report only one result for each USB standard. This is calculated from the average of all available ports.

We won’t deprive you of network bandwidth tests either. We move large files in both directions within a local network between the motherboard network adapters and the Sonnet Solo10G 10-gigabit PCIe card. This from the aforementioned Samsung 980 Pro SSD to the Patriot Hellfire (480 GB), which is still fast enough to not slow down even the 10 Gb adapter.

   

The results of all performance tests are averaged over three repeated measurements for high accuracy.

CPU settings…

We primarily test processors without power limits, the way most motherboards have it in factory settings. For tests that have an overlap with power, temperature and CPU clock speed measurements, we also observe the behavior of boards with a power limit according to Intel’s recommendations, where we set PL1 to the TDP level (125 W) while respecting the Tau timeout (56 s). The upper limit of the power supply (PL2/PTT) is set in the BIOS according to the official values. For Core i9-13900K it is 253 W, for Core i9-12900K it is 241 W. On AMD platforms with the Ryzen 7950X test processor, the reduced power supply mode represents a TDP setting of 105W with a PPT of 142W. Such a load also corresponds to unconstrained power supply of the Ryzen 7 7700X and Ryzen 5 7600X processors. Aggressive overclocking technologies such as PBO2 (AMD) or MCE (Asus) and similar are not covered in standard motherboard tests.

… and application updates

Tests should also take into account that over time, individual updates may skew performance comparisons. Some applications we use in portable versions that do not update or can be kept on a stable version, but for some this is not the case. Typically games get updated over time, which is natural, and keeping them on old versions out of reality would also be questionable.

In short, just count on the fact that the accuracy of the results you are comparing with each other decreases a bit as time goes on. To make this analysis easier, we’ve listed when each board was tested. You can find this out in the dialog box, where you can find information about the date of testing. This dialog is displayed in the interactive graphs, next to any result bar. Just hover over it.

Motherboards for the AMD AM5 platform with chipsets without “E” in the designation have weaker connectivity derived from the processor, but if you do not require PCIe 5.0 for the graphics card, you do not really need to worry. And not at all with the Aorus X670 Elite AX board, which defends the “Elite” label without the slightest difficulty. For proper features, but also for the fact that Gigabyte has once again pushed the performance more than usual.

Methodology: How we measure power draw

In contrast to the Z690/B660 tests, we’ll simplify it a bit and measure only the CPU power draw on the EPS cables. This means that (also for the sake of best possible clarity) we omit the 24-pin measurements. We have already analysed it thoroughly and the power draw on it doesn’t change much across boards. Of the ten boards tested with an Alder Lake processor (Core i9-12900K), the power draw at 12 volts of the 24-pin connector ranges from 37.3–40.4 W (gaming load, graphics card power supply via PCI Express ×16 slot), at 5V (memory, ARGB LEDs and some external controllers) then between 13.9–22.3 W and finally at the weakest, 3.3-volt branch, the power draw of our test setup tends to be 2.2–3.6 W.

On top of the CPU power draw, which also takes into account the efficiency of the power delivery, this adds up to some 53–66 W under gaming/graphics load and only 15–25 W outside of it, with the graphics card idle. We already know all this from older tests, and it will be no different on the new boards, and as the number of measurements increases, reducing measurements that worsen orientation is beneficial. But from the text above, you know how much to add for the total power draw of the motherboard components to the CPU’s majority power draw.

The situation will be a bit different on AMD platforms, for those we will deal with what is the power draw on which branch of the 24-pin, but already in a separate article that will better highlight this topic. In a large comprehensive motherboard test, these measurements disappear, they do not attract enough attention.

We measure the power draw of the CPU (and its VRM) on the power supply cables, with calibrated Prova 15 current clamps and a calibrated Keysight U1231A multimeter. The clamps measure the electric current, the multimeter measures the electric voltage. In the union of these two electrical quantities, we finally obtain the exact power draw. We measure this in different loads on the CPU. The maximum multithreaded load is represented by Cinebench R23.

   

Lower, gaming load by Shadow of the Tomb Raider (1080p@high), single-threaded load by audio encoding (reference encoder 1.3.2, FLAC with bitrate 200 kbps) and idle power draw is measured on the Windows 10 desktop when only basic operating system processes and launchers of some test applications are running in the background.

Motherboards for the AMD AM5 platform with chipsets without “E” in the designation have weaker connectivity derived from the processor, but if you do not require PCIe 5.0 for the graphics card, you do not really need to worry. And not at all with the Aorus X670 Elite AX board, which defends the “Elite” label without the slightest difficulty. For proper features, but also for the fact that Gigabyte has once again pushed the performance more than usual.

Methodology: Temperature and frequency measurements

By far the most critical part in terms of temperatures on the motherboard is the power delivery (VRM) for the CPU. This is where we return to the Fluke Ti125 thermal imager, which produces temperature maps that can be used to locate the average temperature, as well as the hottest point. We record both these values (average and maximum temperature on the Vcore) in graphs, and we will later evaluate the efficiency of the VRM heatsinks based on the maximum one. However, we lack a suitable thermometer for that yet. Of course, the thermovision is implemented without a heatsink, and a thermocouple needs to be installed on the hottest MOSFET to detect the reduction of temperature with a heatsink. This will be added soon.

Thermal imaging always relates to operating with the more powerful of the pair of test processors. With it, the differences and possible limitations or impending risks (for example, even from thermal throttling) become more apparent. In order to have a good view of the VRM, we use an Alphacool Eisbaer 360 liquid cooler with the fans fixed at full power (12 V) instead of a tower cooler (from the CPU tests). The temperature tests also include CPU temperatures for completeness, and we also test the efficiency of the supplied SSD heatsinks as part of the motherboard tests. These are already included with virtually all better motherboards, and so the question naturally arises whether to use them or replace them with other, more finned ones. We will test these heatsinks on a Samsung 980 Pro SSD during ten minutes of intense load in CrystalDiskMark. Finally, the temperature of the chipset’s southbridge and the cooling efficiency in this direction is noteworthy as well.

All tests are conducted in a wind tunnel, so full system cooling is provided. This consists of three Noctua NF-S12A PWMs@5V (~550 rpm) . Two of which are intake, one is exhaust. But the three fast AIO fans also function as exhaust fans, so there is underpressure in the case.

The temperature at the entrance to the tunnel is properly controlled and ranges between 21-21.3 °C. Maintaining a constant temperature at all times during testing is important not only for the accuracy of the temperature measurements, but also because a higher or lower ambient temperature also affects the eventual behaviour of the processors’ boost. And we also properly monitor and compare the clock speeds, whether under all-core load or even single-threaded tasks. We use the HWiNFO application to record the clock speeds and temperatures of the cores (sampling is set to two seconds).

Maintaining a constant temperature at the intake is necessary not only for a proper comparison of processor temperatures, but especially for objective performance comparisons. The clock speed development, and specially the single core boost, is precisely based on the temperature. Typically in summer, at higher temperatures than is normal in living quarters in winter, processors can be slower.

Temperatures are always read as maximum (both from the VRM thermovision and average, but still from the local maximum values at the end of Cinebench R23). For Intel processors, for each test we read the maximum temperature of the cores, usually all of them. These maxima are then averaged and the result represents the final value in the graph. From the single-threaded workload outputs, we extract only the recorded values from the active cores (there are usually two of these, and they alternate between each other during the test). For AMD processors it is a bit different. They don’t have temperature sensors for each core. In order to make the procedure methodically as similar as possible to the one we apply on Intel processors, we define the average temperature of all cores by the highest value reported by the CPU Tdie (average) sensor. However, for single-core workloads we already use the CPU sensor (Tctl/Tdie), which usually reports a slightly higher value that better corresponds to hotspots of one or two cores. However, these values as well as the values from all internal sensors should be taken with a grain of salt, the accuracy of sensors across CPUs varies.

Clock speed evaluation is more accurate, each core has its own sensor even on AMD processors. However, unlike the temperatures, we write the average values of the clock speeds during the tests in the graphs. We monitor the temperatures and clock speed of the CPU cores in the same tests in which we also measure power draw. Thus, sequentially from the lowest desktop idle load in Windows 10, through audio encoding (single-threaded load), gaming load in Shadow of the Tomb Raider to Cinebench R23.

Naposledy sme sa zaoberali základnou doskou, ktorá, ktorá je aj vďaka nižšej cene vhodná najmä na použitie s lacnejšími procesormi. Teraz tu máme o zhruba 50 eur drahšiu Gigabyte B660 Aorus Master DDR4. Príplatok tu má jasné opodstatnenie a odzkadľuje sa na lepších vlastnostiach. Napájacia kaskáda je výrazne efektívnejšia, chladiče sú účinnejšie a výbava je celkovo bohatšia, vrátane svetielok.

Audio encoding

Test environment: Audio encoding is done using command line encoders, we measure the time it takes for the conversion to finish. The same 42-minute long 16-bit WAV file (stereo) with 44.1 kHz is always used (Love Over Gold by Dire Straits album rip in a single audio file).

Encoder settings are selected to achieve maximum or near maximum compression. The bitrate is relatively high, with the exception of lossless FLAC of about 200 kb/s.

Note: These tests measure single-thread performance.

FLAC: reference encoder 1.3.2, 64-bit build. Launch options: flac.exe -s -8 -m -e -p -f

MP3: encoder lame3.100.1, 64-bit build (Intel 19 Compiler) from RareWares. Launch options: lame.exe -S -V 0 -q 0

AAC: uses Apple QuickTime libraries, invoked through the application from the command line, QAAC 2.72, 64-bit build, Intel 19 Compiler (does not require installation of the whole Apple package). Launch options: qaac64.exe -V 100 -s -q 2

Opus: reference encoder 1.3.1, Launch options: opusenc.exe –comp 10 –quiet –vbr –bitrate 192

Conclusion

The Aorus X670 Elite AX motherboard is specific in that its results deviate from other models more than usual. To one side and the other. Across tests, the processor can perform better on it even compared to competing models at twice the price. This is due to Gigabyte taking a more aggressive approach to memory subsystem setup, resulting in lower RAM latencies and thus higher performance in selected applications.

However, the increase in practice is always quite small, up to 5% compared to the MSI MEG X670E. Sometimes, however, this performance difference in favor of the Aorus X670 Elite AX borders on zero. It depends on which application can benefit to what degree from the higher memory controller clock speed (Uncore), which the board sets to 3000 MHz when AMD EXPO is enabled. Most other boards stay at the more conservative 1500 MHz and therefore a slightly lower performance is achieved. If you manually set 1500 MHz for the Aorus X670 Elite AX as well, these differences naturally fade away.

Gigabyte gives a certain performance advantage for ordinary users who simply activate the memory profile of their modules and do not deal with it anymore, but on the other hand, there is also a higher risk of incompatibility and the fact that in different combinations of memory and processors, everything may not work. But it is always possible to decrease the UCKL/clock speed of Uncore manually. This would be it, about things that lead to higher computational and gaming performance. But then, compared to other boards, we also measured speed reductions on some interfaces, and quite significantly.

Lower than you might expect is the USB 3.2 gen 2×2 performance. Specifically for the Type-C external connector. While the sequential read speeds of the test device on other boards average just over 2 GB/s, here it is 25% less (1.5 GB/s), while the controller is the same as, for example, the MSI MEG X670E Ace (1987 MB/s). We can surmise that this degradation arises at the level of lower quality PCBs with more significant interference to data signals. PCBs with X670 chipsets are apparently subject to lower manufacturing tolerances (e.g. in terms of shielding quality) than X670E boards.

Also slower are the M.2 slots for SSDs brought out of the south bridge, but this is no longer compared to the MSI MEG X670E Ace (and boards with X670E chipsets), for which the same is true, but compared to Intel boards. For those, sequential read performance corresponds to roughly 500 MB/s more.
However, the speed of the M.2 slots connected to the CPU is no longer lagging behind Intel platforms. Such transfer speeds of the Aorus X670 Elite AX’s 2.5 Gb Ethernet connection are already higher than some Intel Zx90/Bx60 boards. Although, that is, just a hair, as most boards (including the Aorus X670 Elite AX) are approaching the limits of the interface.

We come to the evaluation of the CPU power delivery after these, shall we say, unusual things, only in the third row. And here it must be stated that it is very robust and well prepared even for performance increase by overclocking (via PBO, for example). It handles the Ryzen 9 7950X quite easily even without a heatsink (with temperatures on the voltage regulator housings down to 55 °C). Power efficiency is probably average or slightly above average. This will become more apparent over time as we compare more boards with AMD chipsets.

The SSD cooler is average (the first one, on the M.2 slot with PCIe 5.0 support) and above average (the big one, shared for three SSDs), as far as cooling effectiveness is concerned.

From the usual features, the Aorus X670 Elite AX board deserves praise for the above-standard number of USB ports, both external (13) and internal (two 19-pin USB 3.2 gen. 1 connectors are available for the front panel of the cases, which is not quite commonplace). If any expense has been spared anywhere, it’s on the overall weaker audio system, which is commanded by a Realtek ALC897 chip. Many may have complaints about this, but who knows if those fears of inferior sound aren’t overblown. We are looking for ways to be able to accurately measure and judge these aspects around audio as well.

The Gigabyte Aorus X670 Elite AX is a remarkable motherboard that can’t be faulted in any major way, and because of the nature of the factory BIOS settings may represent a “more powerful choice” (in terms of both gaming and work use). The price is higher, but competing boards with similarly rich features are not cheaper.
