AMD Ryzen 7 7700X: More efficient, but much weaker than Core i7

It clearly outperformed its predecessors (including the R7 5800X) and also the Core i9-10900K, which has two more cores. But it can’t compare with the Core i7-13700K in heavy MT workloads, and that’s just a month after its release. In ST loads, however, it’s even performance-wise, as in games, where Ryzen 7 is more efficient. Whether the R7 7700X is worth more than the Ci7-13700K for similar money, however, you’ll have to judge for yourself. Read more “AMD Ryzen 7 7700X: More efficient, but much weaker than Core i7” »

Ryzen 5 7600: Raphael in AMD’s most popular series scores again

This time, it wasn’t as long a wait as for the Ryzen 5 5600. On the contrary, the Ryzen 5 7600 came out very shortly after the faster model with the “X” in the name. AMD apparently hurried with this lower-power model also because of dissatisfied reactions that 7600X criticize the worse cooling. With the significantly more efficient R5 7600, the situation with silicon is brighter. Plus it’s cheaper and doesn’t lose all that much in performance.

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

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

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” »

AMD RDNA 3 details: architecture changes, AI acceleration, DP 2.1

November 3 saw the expected unveiling of a new generation of Radeon graphics cards from AMD with RDNA 3 architecture, a competitor to the GeForce RTX 4000, the already selling new GPU generation from Nvidia. In this article, we’ll discuss the chiplet design of the new 5nm AMD GPUs, the changes in architecture, and the new functionality and features that they bring. RDNA 3 has a lot of new stuff compared to the previous generation. Read more “AMD RDNA 3 details: architecture changes, AI acceleration, DP 2.1” »

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

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

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?

AMD Ryzen 5 7600X: The most popular Core i5 declassed

The cheapest Ryzen 7000 processor (7600X) is a class above Intel’s cheapest Core i5-class processor (12400). Ryzen dominates in virtually everything, and it does so at higher efficiency. Yes, it’s not the same price range, and the R5 7600X is ultimately “killed” by the high price (not just in terms of the CPU itself, but the entire platform), but that doesn’t change the fact that it’s a great processor.

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.

AMD Ryzen 9 7900X test: A BANG of an intergenerational leap

More aggressive power limits? Okay, but at a higher efficiency than Intel can do, AMD told itself while working on the Ryzen 7000 processors. And that’s how it really is, despite record-high clock speeds that are truly unusual for a new, unrefined manufacturing node. If this is just the beginning… In any case, not everything is rosy and AMD’s new processors have downsides that will need to be addressed in the future.

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.

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

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.

AMD Ryzen 7000 announced: models, specs, pricing, availability

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” »

AMD Ryzen 7 5800X3D: Best for gaming? In practice, rarely

AMD’s first processor with 3D V-cache is a rather controversial piece of hardware. Sure, it may be the ultimate in gaming performance, but the desired effect is more “on paper” than practical, and when it does come, it’s in very rare cases. So that you don’t end up disappointed with a virtually single-purpose processor that may not even excel at gaming, we’ve broken it all down in detailed tests.

Leaked RDNA 3 GPU details: Has AMD underestimated Nvidia?

Major news has surfaced about AMD’s upcoming RDNA 3 architecture based 5nm GPUs. These chips will form the basis of Radeon RX 7000 generation graphics cards, which will compete with Nvidia’s GeForce RTX 4000 GPUs. Angstronomics has published their specifications as well as chip sizes, which raise doubts whether they can have competitive performance. On the other hand, they could be relatively low-cost.
