Asus TUF Gaming B660 Plus WiFi D4: Entry level for Core i9 too

Graphics effects: Adobe After Effects

Alder Lake CPUs’ favorable price/performance ratio was initially spoiled by expensive motherboards. However, after the arrival of models with Intel B660 chipsets, the unfavorable situation began to turn around and in some cases quite dramatically. Asus TUF Gaming B660 Plus WiFi D4 with support for DDR4 memory, which is far cheaper than DDR5, can handle even the fastest CPUs. And the vast majority of users won’t even feel any bottlenecks.

With this article, we’ll follow the tests of the MSI MAG B660M Mortar WiFi, although the Asus TUF Gaming B660 Plus WiFi D4 doesn’t directly rival it. It doesn’t support DDR5 type memory, but “only” DDR4 and it’s a cheaper board as it is. TUF Gaming B660 Plus WiFi D4 is priced almost at the bottom end of ATX motherboards with Intel B660 chipsets. So naturally it’s expected to underperform, but it does so at a lower price. And percentage-wise at a significantly lower (price) if you are considering pairing with lower-end processors up to Core i5-12500. Besides the fact that the board itself is a bit cheaper (TUF Gaming B660 Plus WiFi D4), you mainly save on DDR4 memory, without which you can’t build a reasonable mid-range configuration. So much for the brief introduction of the TUF Gaming B660 Plus WiFi D4, and now you’re in for what you love – in-depth analysis.

Asus TUF Gaming B660 Plus WiFi D4

The TUF series of motherboards no longer represents the high-end as it once did. This space, as far as “gaming” motherboards are concerned, Asus has left for the ROG series. In today’s world, The Ultimate Force brand represents affordable hardware that still has to meet higher performance demands.

The board is in ATX format (305 × 244 mm), from which good expansion possibilities derive. The PCI Express slots are two ×16 and two ×1. Only the first one is a full-size 16-lane one. It is connected to the processor, supports the PCIe 5.0 standard, and is also reinforced with the usual metal bracket that reduces the strain on the contacts when a greater force is applied, typically by a graphics card. It is also worth mentioning the sufficient distance from the CPU socket, which makes it possible to comfortably install the largest coolers.

The second PCIe ×16 slot has contacts for only four lanes, which can be useful for SSD cards, for example. The two short PCIe ×1 slots, on the other hand, find their use for a sound or network card. The board only has one or the other at the entry level. Reservations can be directed mainly at the outdated Realtek ALC897 sound chip, which Asus does not even mention in the specifications. The networking part with a 2.5-gigabit Intel I225-V adapter is more decent, but there’s still only one RJ-45 port. Considering that Asus pushes the price to the minimum (and succeeds in being practically the cheapest in this category), we can’t fault either of the things too much.

There are up to three M.2 slots available for fast SSDs, but the third one is connected to the south bridge (B660) with only two PCIe 4.0 lanes, so it slows down the more powerful SSDs. All M. 2 slots exclusively use the PCI Express interface, which means SATA SSDs don’t work. But at least this removes the worry of learning shared lanes with SATA connectors. Although only four of these are brought out, it is possible to use them all, even in addition to the three fitted SSDs in M.2 format.

   

Internal equipment includes a generous number of (A)RGB LED connectors – three modern (5V) and one analogue (12V) for backward compatibility with older components. You probably won’t miss the connectors for connecting fans (or pumps) either, there are plenty of those too – seven.

The external connectors are thinner, but there is a little of each. There’s even a 20-gigabit USB-C 3.2 gen. 2×2 port, alongside one 10-gigabit (3.2 gen. 2 type A), and while there are fewer USB ports, you can see that Asus has at least tried to keep the slow ones to a minimum. There’s only one USB port with support for the old 2.0 standard (it doesn’t matter at all, because you’ll connect a keyboard or mouse that doesn’t need more to live anyway), and half of the USB ports are 3.2 gen. 1 (5 Gbps).

We’ve already talked about one RJ-45 connector for a wired network connection, then there are two more SMA connectors on the rear panel for WiFi antennas and five 3.5 mm jacks with one SPDIF optical output for the audio adapter. Of the video outputs, there are two digital ones – DisplayPort 1.4 and HDMI 2.1 (i.e. with support for 3840×2160 px resolution at 60Hz via the iGPU as well).

The 11-phase (10+1) power delivery has two robust heat sinks (161 + 79 g) with both lengthwise and cross-cut profiling. This for greater air contact. BGNO 1T25 voltage regulators are relatively unknown and their parameters are also more difficult to get hold of. Firstly because they only have datasheets in scanned PDFs, secondly because they are from Alpha Semiconductor. We encounter components from this company only sporadically on motherboards. Anyway, the total current capacity of the Vcore is 500 A, which is enough for the Core i9-12900K without power limits. The VRM driver is the time-proven ASP2100 EPU.

   

Among the small details, the mounting system of the SSD M.2 is noteworthy. On the spacers are rotatable locking levers. With them, working is significantly more comfortable than with tiny screws.

In the next chapter we will go through the BIOS and then come the detailed tests, from which the motherboard can be comprehensively evaluated. Hundreds of measurements will test it through and through.

Alder Lake CPUs’ favorable price/performance ratio was initially spoiled by expensive motherboards. However, after the arrival of models with Intel B660 chipsets, the unfavorable situation began to turn around and in some cases quite dramatically. Asus TUF Gaming B660 Plus WiFi D4 with support for DDR4 memory, which is far cheaper than DDR5, can handle even the fastest CPUs. And the vast majority of users won’t even feel any bottlenecks.

What it looks like in the BIOS

Screenshots correspond to the latest BIOS version 1013 at the time of testing. The introductory EZ mode screen gives a good overview of the basics (RAM detection, SSD, connected fans, …) including CPU temperature and its operating voltage.

The F4 key can also be used to centrally control the illuminated elements. These are minimal on the board (only on the bottom right side behind the SATA ports), but Aura Sync also works from the UEFI interface.

The advanced mode naturally brings a larger portion of tuning options. In the PCI Express settings it is possible to control the ReSizable BAR for the graphics card. We always test everything with ReBAR disabled, because its operation changes rapidly over time and this is undesirable for the consistency of motherboard tests (unnecessary distortions would occur). But you should feel free to enable ReBAR, as long as it doesn’t slow down your applications/games.

   

On the first PCI Express ×16 slot, it is also possible to regulate the support of its speed standard. This can be set manually from PCIe version 5.0 to 1.0 if required.

For the RAM profile settings, Asus has finally started to use a more understandable unified designation XMP. In advanced mode, these options are in the Ai Tweaker (Ai Overclock Tuner) tab. The next position over (Advanced tab) can then be used to adjust the operation of the TPM.

   

And there’s one more change that Asus has committed to. The company’s boards have been known in the past to respect Tau’s power-down timeout (to PL1/TDP values) under long load. This is no longer the case, but at the same time there are some limitations. Namely, both short and long term power is aligned to PL2 (so power is stable and doesn’t drop over time), which in the case of the test Core i9-12900K is 241W.

For objective comparison with other boards we have adjusted this limit, for standard tests it is removed completely (i.e. both PL1 and PL2 are set to 4095 W) and for reduced power tests the settings are modeled after Intel’s recommendations. PL2 is left at 241 W, but we already have PL1 reduced to 125 W (TDP). And the timeout manually selected at 56 seconds. To add to it, Asus has some strange stopwatches, because the drop in power draw (and reduction) of frequencies occurs significantly earlier, as you can also see in the flow charts of the respective power draw tests.

This board does not have an external generator to significantly increase the BCLK clock for locked processors, nor does any other board in this price range.

Within the detailed settings, you can also manage the number of active cores and or completely disable E cores or customize LLC or play around with power saving settings (even outside of the traditional power saving features). However, we have not interfered with these things and they are left at the default settings.

      

Among the temperature sensors you will find one in the VRM (on the thermistor), but the chipset temperature information is missing – the “motherboard” temperature is something else.

The BIOS options are quite wide and besides managing basic things, it is also possible, for example, to format connected SSDs, which is something not all motherboards allow.

   

While somewhere Asus has added, somewhere else it has taken away. For example, in Q-Fan the PWM curve cannot be optimized for an optional temperature sensor, say a VRM.

However, you can adjust the PWM intensity waveform on all available connectors. Manually or select one of the four preset profiles (Silent, Turbo, Full Speed) with respect to what you want to achieve. The good news is that DC regulation is retained, which is especially useful for older fans without PWM support.

Alder Lake CPUs’ favorable price/performance ratio was initially spoiled by expensive motherboards. However, after the arrival of models with Intel B660 chipsets, the unfavorable situation began to turn around and in some cases quite dramatically. Asus TUF Gaming B660 Plus WiFi D4 with support for DDR4 memory, which is far cheaper than DDR5, can handle even the fastest CPUs. And the vast majority of users won’t even feel any bottlenecks.

Gaming tests…

The vast majority of tests is based on the methodology for processors and graphics cards. The choice of games is slimmer for motherboards, but that’s in order to be able to run all the tests with two different processors as promised. Each board will always be tested with a more powerful processor from the top end, but also with a weaker, average one. The more powerful variant on the LGA 1700 platform is the Core i9-12900K and the mid-range one is the Core i5-12400.

Based on tests with processors from different classes, you’ll be able to easily decide whether a more expensive motherboard for a cheaper processor makes sense for you or, conversely, how good of an idea it is to skimp on a cheaper motherboard while using a more expensive and more powerful processor, which naturally also has higher power draw and places higher demands on the overall quality of the motherboard.

We’ve selected five titles from the games and we’re testing them in two resolutions. There are significantly fewer games than in the CPU or graphics card tests, but there is just enough for the motherboard tests. Few people consider performance in a particular game when choosing a motherboard. But an indicative overview of how a motherboard shapes gaming performance (compared to other motherboards) is a must. To avoid significantly skewing the result over time, we 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. For newer games, there might be some performance changes over time (with 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) 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 and to what extent can impact the graphics card’s performance for some reason. In contrast, a setup with Full HD resolution and with graphical details reduced to “High” will also reflect the CPU’s influence on 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 best accuracy.

CPU settings…

We primarily test processors without power limits, the way most motherboards have it in factory settings. For tests that have overlap with power, temperature and CPU frequency measurements, we also observe the behavior of boards with power limits set according to CPU manufacturers’ recommendations. We set PL1 to the TDP level, respecting also the tau timeout (56 s) for Intel CPUs. The upper power limit (PL2/PPT) is also set according to the official CPU specifications. Technologies for aggressive overclocking, such as PBO2 (AMD) or ABT (Intel), MCE (Asus) and the like, are not dealt with in our 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.

Methodology: How we measure power draw

Motherboard “power draw” analysis is an extremely attractive topic if approached methodically. What does it mean? Measuring the electric current and voltage directly on the wiring that powers the motherboard. Naturally, the processor, or the processor power supply, has the most significant draw, which we measure separately – just as in processor tests.

In addition to the EPS cable, there is also a 24-pin ATX cable with multiple voltages, which is good to keep track of. The key ones are +3.3 V (from which the chipset is typically powered), +5 V (memory) and +12 V, from which the PCI Express slots are powered, and the biggest draw will be in the case of our test configuration on the graphics card. All of these wires are closely monitored. But then within the ATX connector there are also a few relatively unimportant branches that are no longer even used in modern computers (that is, -12 V and -5 V) or are relatively unimportant in terms of power draw. For example +5 VSB (power supply for USB or ARGB lighting even when the computer is switched off; this can usually be switched off in the BIOS) or PG (Power Good), which is only informative and during operation it is only “an also-run”. These branches (-12 V, -5 V, +5 VSB and PG) always have only one wire and often with a smaller cross section, which is also a sign of always very low power draw.

The 24-pin wires on which we measure the power draw are always connected in parallel and are at least in pairs (+12 V) or greater in number. For example, the +3.3 V branch uses four conductors to increase the cross section and the +5 V branch has up to five. However, this branch is quite oversized from today’s point of view, as historically it was intended to power more HDDs or their logical part (+12 V is used for the mechanical part).

We use a shunt of our own making to measure the draw from the 24-pin. This is built on a very simple principle and consists of very low-value resistors. The value is set so low that the voltage drop is not higher than the ATX standard. Based on the known resistance in the circuit and the voltage drop across it, we can calculate the electric current, and once the output is substituted into the known formula to calculate the power, the mathematics is easy. Samples during the course of the tests are recorded using the Keysight U1231A multimeter array via a service application that allows the recorded data to be exported in CSV. And that’s the final destination for creating line graphs or counting averages (into bar interactive graphs). That’s how simple it is.

For completeness it is good to add that the current clamps for measuring the current draw from the EPS cables (power supply to the processor) are Prova 15. These will soon be replaced by a more practical solution for desktop use, namely a similar shunt we use for the ATX connector. The only reason it is not yet in circulation is its more complex design (as it has to account for very high currents) and the need for thorough testing, which we are yet to get to. Since we place a high emphasis on accuracy in our tests, all measuring devices are properly calibrated.

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.

Thermovision 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 a vacuum 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 behavior of the processors’ boost. And we also properly monitor and compare the frequencies, whether under all-core load or even single-threaded tasks. We use the HWiNFO application to record the frequencies 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 frequency 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.

Frequency 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 frequencies during the tests in the graphs. We monitor the temperatures and frequencies 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.

Conclusion

Few pieces of hardware that pass the HWCooling testlab leave such a good impression as the Asus TUF Gaming B660 Plus WiFi D4 motherboard. This is despite the fact that there is a greater number of negatives in the plus and minus table. However, these are natural and stem from the low retail price, which is key for this board. The important thing is that all the shortcomings are mild and the low price justifies them.

Many editorials will discredit this board on the higher VRM temperatures, but unjustifiably so. As scary as 97°C looks on thermal imaging, without heatsinks and with the Core i9-12900K, it’s a great result. With heatsinks, it’s up to 80°C and there is no performance degradation (by inhibiting multiplier crashes) even with the most powerful processors that can currently be fitted to the LGA 1700 socket.

We have a small complaint only about the 12-pin EPS. With a larger 16-pin power supply, even cheaper power supplies with smaller wire gauge will get less hot inside the connectors. But that’s really a cosmetic issue. Especially because this board is expected to work with cheaper processors with power draws up to 150W, even though the VRM can handle twice that. After leveling the draw to 125 W the temperture of the voltage regulators is pleasantly low.

The above is not to say that the board is suitable for high-end processors. It is not, but for a reason other than the “capacity” of the VRM. The power delivery is cheaper, and performance and power draw tests show it to be less efficient. With similar and rather a hair lower performance (but this is also due to slower DDR4 memory) compared to MSI MAG B660M Mortar WiFi there is a higher power draw. And even in AVX load, in which the TUF Gaming B660 Plus WiFi D4 reduces the multiplier (by 3).
This can be partially compensated for by manually tuning the undervolting, but it doesn’t change the fact that the performance per unit of power draw will be lower on the Asus board.

In return, the off-load regulation is excellently handled, in which even the power draw of the Ci9-12900K processor is always pleasantly low. The Intel I225-V network adapter is also surprisingly better than on most other boards. Compared to the Realtek 8125BG on the B660M Mortar, the recording speed is achieved as expected. There’s even a 20-gigabit (3.2 gen. 2×2) USB Type-C port among the external connectors. The equipment is really decent for a board well under two hundred euros, or rather the savings are in places that users with a lower budget won’t be too bothered about. Especially in combination with cheaper processors.

We won’t discuss the performance results in detail this time, so we don’t have a board with DDR4 memory to compare yet (it will come in the next test) and the differences with B660M Mortar speak more about the impact of differently fast memories. If this issue of comparing DDR5 with DDR4 memory interests you, you can dig through the tests. But you’d better wait for the upcoming measurements, where the memory performance comparison will be based on tests of otherwise identical boards (and in addition to 3600 MHz modules with average speed, we’ll test faster DDR4 with 4400 MHz). But even these tests show that performance doesn’t significantly improve with 5200 MHz DDR5 over DDR4, even with a Core i9-class processor. The results are very similar, and you’ll also come across applications that benefit from DDR4’s lower latencies with otherwise significantly lower bandwidth.

But back to the TUF Gaming B660 Plus WiFi D4. A very solid motherboard at a very nice price. As long as you don’t mind weaker VRM efficiency or simpler fan control options by today’s standards, we approve of this choice.
