How good is AMD’s AVX-512? Does it improve Zen 4 performance?

When Intel Rocket Lake processors with AVX-512 instructions came out last year, we took the opportunity to test how they can improve performance in the x265 video encoder. Since the now-released Ryzen 7000 processors with Zen 4 architecture also support AVX-512, and there has been a lot of debate about the pros and cons with Rocket Lake, we went back to that test to see how AMD’s alternative implementation fares in it.

Zen 4 has a thermal boost, too. 5.85 GHz only at sub 50 °C temps

It is often commented on that Intel processors (like the upcoming Raptor Lake) have many different boost modes with various conditions, for example the temperature-dependent Thermal Velocity Boost. But it turns out that the Ryzen 7000s have something similar. According to unofficial information the top Ryzen 9 7950X model will also reach its maximum frequency only at low temperatures – impractically low, even.

Full specs of AMD Ryzen 7000 processors out. Major TDP bump

According to leaks, AMD is expected to release their new desktop processors with Zen 4 architecture and 5nm manufacturing process in six weeks and will formally unveil them before the end of the month. And it seems the parameters of these CPUs are now also out. We even have them from two sources, improving the odds this info is legit. Unfortunately, there’s bad news in the power consumption department: TDPs are getting much worse. Read more “Full specs of AMD Ryzen 7000 processors out. Major TDP bump” »

AMD has self-leaked Ryzen 7000 models. Cheaper 7700X octa-core?

Although AMD’s new desktop processors with Zen 4 architecture and the new AM5 platform seem to be very close with release probably less than two months away, the company managed to keep the specs under wraps. It’s not completely leak-proof though. The company’s own website actually revealed information about the models coming out in the first wave of new processors. There’s four of them, one being somewhat of a surprise. Read more “AMD has self-leaked Ryzen 7000 models. Cheaper 7700X octa-core?” »

Intel Arc A380 GPU performance is worse than RX 6400 after all

After missing previous 2021 and Q1 2022 deadlines, Intel Arc discrete desktop graphics cards with the Xe HPG gaming architecture went on sale in China this month. But instead of some bombastic arrival, Intel is releasing them rather quietly, first only in China and only in the OEM market. But maybe that’s because they’re not really impressive yet – the first Arc A380 model seems to be falling well short of expectations in tests.

AMD reveals future processor plans and first details on Zen 5

From AMD’s Financial Day 2022 conference on Thursday, we’ve already covered here what the company said that was new about Zen 4 and Ryzen 7000 (especially the IPC reveal). Now let’s take a look at the roadmaps for future processors. The company has revealed these plans for practically all market segments, which comes after a long time during which we didn’t see any roadmaps from it and could only rely on unconfirmed leaks.

More Ryzen 7000 details: TDP and PPT, iGPU features and more…

We’ve already had an article about AMD’s Ryzen 7000 CPUs and what was revealed about them at Computex 2022, but we need to revisit them once more. AMD has since dropped more details about the features of these CPUs, new instructions and technologies. The situation around TDP and maximum power draw was also clarified, and AMD also said something about the reported performance numbers that caused a bit of a stir on Monday.

AMD Ryzen 7000 sample leaked: Zen 4 cores boost up to 5.2 GHz

AMD CPUs bringing the 5nm manufacturing process, the new Zen 4 architecture and also a new desktop platform (AM5) with DDR5 memory, look to be quite close, these Ryzen 7000 processors could be here as early as September. An interesting teaser has emerged now: it seems AMD tested a Ryzen 7000 sample in the Phoronix Test Suite, and the result went public in the OpenBenchmarking database. And it shows quite interesting specifications. Read more “AMD Ryzen 7000 sample leaked: Zen 4 cores boost up to 5.2 GHz” »

Next year’s Ryzen 7000 APUs will have RDNA 3 GPUs

This fall, AMD is releasing a new generation of graphics cards (Radeon RX 7000) and Ryzen 7000 “Raphael” desktop processors with Zen 4 cores. However, this architecture should also be adopted quite quickly by Ryzen 7000 “Phoenix” APU processors for laptops. Little was known about these, but information on them has also started to leak: the Linux driver code has revealed the architecture of the integrated GPU.

Ryzen 7 5800X3D with V-Cache is locked, impossible to overclock

This week AMD announced the April release of the Ryzen 7 5800X3D, claimed to be “the ultimate gaming CPU” (at least amongst Ryzen processors, we’ll see if it beats Intel’s 12th-generation Core). However, this CPU has one flaw for enthusiasts – it’s been confirmed that it is not overclockable. AMD has revealed that this is an unfortunate side effect of the 3D V-Cache, the company reassures us it’s not cracking down on OC as such.

More new budget AMD CPUs, including the quad-core Ryzen 3 5100

AMD is now preparing a sort of mid-generation refresh of its CPU and GPU offerings – Ryzen 5000 and Radeon RX 6000. There have been several reports about them in the last few days, but we’ll have to add one more. It looks like the company will be releasing even more CPUs than the six new models we wrote about last time. Seems the chip crisis is finally getting better and that will bring us a quad-core Zen 3, for example. Read more “More new budget AMD CPUs, including the quad-core Ryzen 3 5100” »

Specs of the integrated GPU coming to Zen 4 Ryzen CPUs leaked

One of the drawbacks of the higher-tier Ryzen processors (3000X, 5000X models) is that they do not have an integrated GPU. However, this should change with the new 5nm Ryzen 7000 generation with Zen 4 architecture. AMD hasn’t announced it yet, but according to numerous leaks, this generation will also already provide integrated graphics. Now another proof has emerged and also some indication of its specs.
