AMD Ryzen 5 3600: Older bestseller head-to-head with new CPUs

Extra tests, Processors | | Ľubomír Samák

One of the most popular CPUs in recent history. That is the Ryzen 5 3600. In stores It’s almost totally unavailable, yet it’s performance numbers are very valuable. Many of you own this processor thanks to its popularity so I presume you will appreciate a little head-to-head with more recent and more available models. From these tests, you will get an idea how the 6 Zen 2 cores stack up against Zen 3 (5600X) or Intel (be it Rocket Lake or Comet Lake).

Gracemont, the (not so) little Alder Lake core (µarch analysis)

Analysis, Processors | | Jan Olšan

Intel has revealed the Alder Lake CPU architecture, or actually two architectures this time. The CPUs are hybrid and besides the main „big“ ones, there are „little“ cores called Gracemont. These are not just for marketing or for low-power idle tasks like in mobile ARM SoCs, however. Gracemont should significantly add to the overall performance, the architecture is actually surprisingly beefy. Our analysis will show you more.

MS allows Windows 11 on unsupported hardware, with caveats

Computers, News, Processors | | Jan Olšan

Since June, hardware requirements of Windows 11 have been a hot topic—the necessity of having TPM 2.0 and the supported CPU list that leaves out some PCs mere three years old. Fortunately, it looks like the hopes that Microsoft will get more pragmatic about this have come true and the company will allow the new OS to be run on older PCs that do not make the cut officially. But it is going to take an extra bit of work. Read more “MS allows Windows 11 on unsupported hardware, with caveats” »

Intel Alder Lake/Golden Cove CPU core unveiled (µarch analysis)

Analysis, Processors | | Jan Olšan

Intel’s Alder Lake CPUs are poised to be the biggest hardware event this year. Intel has unveiled the core architecture of these CPUs and we have analysed the details and new improvements inside. There’s promise of huge performance and one of the biggest architectural leaps in x86 processors, for the first time with six parallel decoders and further IPC increases, showing Intel taking the same path as Apple’s highly effective cores.

AMD Ryzen 5 5600X: Worth €120 more than the Core i5?

Extra tests, Processors | | Ľubomír Samák

We’ve already discussed the middle class Intel processors (Core i5) in tests, but so far without comparing it to the equivalent Ryzen 5. We will gradually add these, but before the R5 3600, do not miss the extensive comparison of R5 5600X to Ci5-11400F. It’s a bit of an unequal fight, as the AMD piece is significantly more expensive, but maybe in your eyes it will defend its price in tasks where it is clearly better than the Core i5 Rocket Lake.

Intel Arrow Lake processors – high performance iGPU with 320 EU

News, Processors | | Jan Olšan

Last week we’ve covered a leaked Intel processor roadmap showing Arrow Lake, Lunar Lake and Nova Lake processors that are to arrive after Alder Lake, Raptor Lake and Meteor Lake. We said to take it with a grain of salt, as that was the first time the Arrow and Nova codenames have shown up. But shorty after, more information on Arrow Lake has come up that could prove its existence. Looks like the mobile will pack a very fast iGPU.

Alder Lake may have a higher power draw. PSU recommendations

News, Processors | | Jan Olšan

Intel will release new Alder Lake desktop processors in three months—with a powerful new architecture and hybrid big.LITTLE approach for the first time. These CPUs, finally manufactured on 7nm process (originally 10nm Enhanced SuperFin), should have significantly better energy efficiency. But it looks thir power needs will go up despite this. Intel is increasing the currents required from PSUs, which could mean higher power draws. Read more “Alder Lake may have a higher power draw. PSU recommendations” »

Review of AMD Ryzen 7 3700X processor. Zen 2 still rocks

Extra tests, Processors | | Ľubomír Samák

Even after the release of the Ryzen 7 5700G, the Ryzen 7 3700X is currently the cheapest octa-core processor. It still doesn’t have a proper successor. The Ryzen 5 5800X is significantly pricier, but it is fully stocked in stores. This last-gen model could thus be considered up-to-date and should not be omitted in comparisons with other processors. It also beats the Rocket Lake Core i7 not only in efficiency but also occasionally in performance. Read more “Review of AMD Ryzen 7 3700X processor. Zen 2 still rocks” »

Intel AVX-512 tested in x265: how to enable it and does it help?

Extra tests, Guides, Processors | | Jan Olšan

The 11th generation Intel Core processors (Rocket Lake) are the first mainstream desktop parts supporting AVX-512 instruction set, previously only available in Xeons or the X299 platform. One area where AVX-512 promises better performance is multimedia. We looked at one use: encoding HEVC video via x265. It’s little known, but x265 does not actually use AVX-512 by default. We’ll show you how to turn it on and what are the effects. Read more “Intel AVX-512 tested in x265: how to enable it and does it help?” »

Intel Core i7-11700KF: A hair slower, but better value than Core i9

Extra tests, Processors | | Ľubomír Samák

8 cores, 16 threads. From this point of view, it is the same configuration as the Core i9-11900K(F). However, the Core i9 is a significantly more expensive processor and, especially in games, it has a much higher power consumption. At the same time, the difference in performance is minimal. It follows that with higher efficiency, the Core i7-11700K(F) has a more attractive price-performance ratio. Read more “Intel Core i7-11700KF: A hair slower, but better value than Core i9” »

MS Flight Simulator July update test: More than twice the FPS

Extra tests, Graphics, Processors | | Ľubomír Samák

The announced update to increase performance in MFS is out, and we have a “before” and “after” comparison for you. Developers has worked to ensure that the processor does not significantly bottleneck the GPU. So far, the performance of the graphics card did not matter much, because only a fraction of its potential was used. But newly, you will achieve better performance on low-end hardware than you did before on a top-end rig. Read more “MS Flight Simulator July update test: More than twice the FPS” »

The new (11400F) vs. older (10400F) Intel Core i5 processor

Extra tests, Processors | | Ľubomír Samák

Intel has practically no direct competition in the segment of cheaper processors. The lowest Core i5 CPUs are significantly cheaper than the Ryzen 5 5600X, which is AMD’s entry level in this class. Therefore, this brotherly duel of the new (11400F) with the older (10400F) Core i5 is more attractive than comparing the processors between the two companies. That was also a wish of one of our readers, and now it is finally coming true. Read more “The new (11400F) vs. older (10400F) Intel Core i5 processor” »

Specs of Intel Alder Lake 125W ‘K’ processors leak: clock rate, PL2

News, Processors | | Jan Olšan

Last week we’ve had reports of the big.LITTLE Intel Alder Lake processors reaching surprising performance: with just 8 “big” cores out of the total 16, they are said to surpass the 32-threaded Zen 3 in Cinebench R20. Now we the specs of all three 125W unlocked models, with clocks and power draw in boost, aka PL2. Looks like 10nm process will finally lower the power consumption compared to the 14nm CPUs—but not by much. Read more “Specs of Intel Alder Lake 125W ‘K’ processors leak: clock rate, PL2” »

Test of AMD Ryzen 9 5950X processor: 32 threads on AM4

Extra tests, Processors | | Ľubomír Samák

The Ryzen 9 5950X is the highest performance processor designed for the “small” AMD AM4 socket. At the same time, it is a rarity that has essentially no competition (Intel has nothing against it) and is roughly halfway to high-end Threadrippers. Compared to those, however, it has a higher gaming performance and a cheap motherboard will also suffice. This processor is even sometimes more power-efficient than the slower 5900X.

Single-thread boost analysis of Vermeer, Rocket and Comet Lake

Extra tests, Processors | | Ľubomír Samák

In a recent test of processors, we focused on everything, even single-threaded boost. We will now take a closer look at it, because its behavior is remarkable. Modern processors also use two cores in turns for single-threaded tasks. This creates a short pause for the unloaded core to cool down. We captured how it works in bar graphs with waveforms, and you will also find out whether the specifications are closer met by AMD or Intel.
