Asus improves board warranty: Memory OC and beta BIOS covered

Motherboards, News | | Jan Olšan

Recently, a controversy has flared up on the web surrounding Asus motherboards. It is related to the issues of Ryzen 7000X3D CPUs killed by excessive VSoC voltage, which was previously set too high by Asus boards (not just Asus ones though). Asus received further complaints after providing a fix as a beta BIOS update that was not officially covered by warranty. The company has now responded by changes that should improve things quite a bit. Read more “Asus improves board warranty: Memory OC and beta BIOS covered” »

AMD fixes bug that kills Ryzen 7000 CPUs, update your BIOS

News, Processors | | Jan Olšan

Last week, cases of destroyed V-Cache using Ryzen 7000 “X3D” CPUs and even a burned socket on the board (the dead CPU probably started drawing excessive current from the VRM through the pins). At first it wasn’t clear if it wasn’t a result of manual overvolting, but AMD announced that they have found the cause of the problem and are releasing board BIOS updates to protect the CPUs from damage, so definitely update.

AMD’s Zen 6 processors will use 2nm process technology

News, Processors | | Jan Olšan

Few days ago there was news that GeForce RTX 5000 graphics (the Blackwell architecture GPUs in them) will not yet use the 3nm manufacturing node, reportedly staying on 4nm technology instead. Now, there is news about another product that will use a new technology for a change – AMD processors with Zen 6 architecture. We learned that thanks to one of the employees leaking this important detail on the LinkedIn social network. Read more “AMD’s Zen 6 processors will use 2nm process technology” »

Ryzen 7000X3D: technical details and asymmetric CCX handling

News, Processors | | Jan Olšan

Last day of February, AMD started selling the Ryzen 7000 processors with 3D V-Cache, the chiplet technology increasing L3 cache capacity. Prior generation (Ryzen 7 5800X3D) proved that this benefited gaming, and it looks like the same is true now. Ryzen 7000s are aimed specifically at gaming PCs, and according to reviews, they seem to have surpassed Intel’s Raptor Lake processors in that and are now holding the gaming performance crown.

Fact check: AMD is not limiting shipments to inflate prices

News, Opinion, Processors | | Jan Olšan

Last week, news stories have emerged that AMD is artificially inflating prices of its processors or GPUs by deliberately underselling the demand. This news has spread a lot. And yet, the report is almost certainly nonsense born out of misinterpretation (or misunderstanding of economics). There’s already been an official denial issued, but the story keeps spreading, so we feel it’s appropriate to address it a bit.

AMD Ryzen 7000X3D release date revealed? (Update: Sadly not)

News, Processors | | Jan Olšan

Last week, AMD has unveiled the awaited expansion of the AMD Ryzen 7000 processor family with “X3D” models with 3D V-Cache. It boosts performance in games, so these could be very good (maybe even the best?) gaming PC processors. AMD has disclosed the specs, but hasn’t given the availability date for these models. We already have this information though, perhaps inadvertently, divulged by the company itself on its website. Read more “AMD Ryzen 7000X3D release date revealed? (Update: Sadly not)” »

AMD launches Ryzen 7040: 4nm APU with Zen 4 and RDNA 3 iGPU

News, Notebooks, Processors | | Jan Olšan

In addition to the AM5 Ryzen 7000 processors with 3D V-Cache and mainstream 65W TDP models, AMD also announced a wholly new offering at CES 2023: the first processors with Zen 4 architecture for laptops. They are based on the all-new Phoenix APU, which is the first 4nm Ryzen chip and the first processor with an integrated RDNA 3 GPU, which will also clock up to 3 GHz. So it’s going to be a very interesting laptop platform. Read more “AMD launches Ryzen 7040: 4nm APU with Zen 4 and RDNA 3 iGPU” »

65W CPU with Zen 4 architecture is coming: AMD Ryzen 7 7700

News, Processors | | Jan Olšan

When the specs of the Ryzen 7000s first leaked, one thing was disappointing. These processors use 5nm process that is much more efficient, yet AMD has not exploited this potential. Likely due to pressure from Intel’s big.LITTLE processors, the company has increased power draw to raise multi-threaded performance and instead of 65W and 105W TDPs, the TDPs went up to 105W and 170W. But lower-power versions are fortunately in the pipeline. Read more “65W CPU with Zen 4 architecture is coming: AMD Ryzen 7 7700” »

Why is Zen 4 so fast in Topaz Labs AI apps? In fact it’s Intel’s doing

Analysis, Extra tests, Processors | | Jan Olšan

Ryzen 7000 with Zen 4 architecture is the first AMD processor to support 512-bit AVX-512 vector instructions. We’ve already discussed their benefits (bigger or smaller) here. But the Zen 4 cores support another instruction set extension that used to be Intel’s pride and joy, and now the roles have reversed a bit: VNNI. It seems to bring huge performance improvements in a number of apps, despite the limited 256-bit width of Zen 4 SIMD units. Read more “Why is Zen 4 so fast in Topaz Labs AI apps?

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

Analysis, Extra tests, Processors | | Jan Olšan

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

News, Processors | | Jan Olšan

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.

Zen 4 architecture: chip parameters and IPC of AMD’s new core

News, Processors | | Jan Olšan

AMD formally launched the Ryzen 7000 (with availability four weeks away though) and confirmed specs and pricing. The company has also disclosed a considerable amount of technical details and more has now leaked from unofficial sources. So let’s have a deeper look at Zen 4 architecture, the 5nm chiplets of the processors and finally the core’s IPC – which has actually improved more than the previously promised +8 to 10 % over Zen 3.

Today in the early morning hours, AMD held an event to officially unveil next generation desktop processors – the Ryzen 7000 with Zen 4 architecture made on 5nm manufacturing process. We learned the final specs of these processors and their new iGPU, as well as a store availability date and the prices the chips will cost. There’s been a surprise change in pricing in contrast with the previous leaks. In any case, Zen 4 is here. Read more “AMD Ryzen 7000 announced: models, specs, pricing, availability” »

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

News, Processors | | Jan Olšan

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?

News, Processors | | Jan Olšan

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?” »
