Intel Core i5-13600K: Better value than Ryzen 5 7600X? Yes and no

The Intel Core i5-13600K processor gives the impression of being from a slightly different class than the Ryzen 5 7600X. AMD’s Raphael with only 6 cores against 14 cores (albeit eight of them only small, Gracemont) of Raptor Lake may look like an underdog that should be significantly cheaper. However, one must be careful when making judgments. Although the Ci5-13600K is a great processor, so is the still only Ryzen 5 7000 in the game so far.

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” »

Older Windows 10 versions like 22H2 slow down Raptor Lake CPUs

The release of Intel Raptor Lake processors also coincided somewhat with the release of the latest update for Windows 10, the 22H2. We write this in this context because it quietly removes the most significant performance shortcomings, and the difference to the detriment of the older build (22H2) can be as much as 57 %. Most of the time this update doesn’t change performance too much, but when it does, it changes it badly. Read more “Older Windows 10 versions like 22H2 slow down Raptor Lake CPUs” »

Intel Core i9-13900K review: Biggest predator in the lake

A fully active Intel Raptor Lake CPU chip, that’s tremendous performance for all situations, but also a lot of worries. These revolve around how to use this great potential and not hold anything back. There are more obstacles than usual. When it’s not on a software basis, it’s a struggle with cooling for a change. And you already know that the 13th-generation Intel Core CPU is sometimes more efficient than the Ryzen 7000. Read more “Intel Core i9-13900K review: Biggest predator in the lake” »

First results of Raptor Lake: A fairy tale in a single thread and…

We’ll be releasing our full tests of the Intel Core i9-13900K (Raptor Lake) tomorrow. The sample arrived at the editorial office after the gallows deadline and it was not possible to make the full tests, but for now we have at least something that may get you in the right mood. One of the pleasant surprises is the higher single-threaded performance at lower power draw than AMD Ryzen 7000 CPUs. And that’s even at a record 5.8 GHz.

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.

Raptor Lake is here: high speed with 7 Ultra node, no price hike

This week, AMD Ryzen 7000 processors and AM5 platform went on sale (we’ve already tested the 7900X). Intel will counter with their own new generation next month: the 13th generation Core “Raptor Lake”, which was unveiled on the same day, albeit with no physical availability yet. We now have definitive specs, as well as pricing. You’ll be pleased to know that most SKUs have not gotten more expensive, even though that was rumored.

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.

End of an era: Intel to stop making Celeron and Pentium CPU

Yesterday we shared the news that EVGA is ending production of GeForce graphics with Nvidia GPUs after more than twenty years. Another “end of an era” moment has however happened virtually at the same time. Intel has announced that it will do away with the historic Pentium and Celeron processor brands that have survived since the 20th century. This is as part of image and branding changes the company is now planning for next year. Read more “End of an era: Intel to stop making Celeron and Pentium CPU” »

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.

Cheaper Raptor Lake CPU will be just rebadged Alder Lake chips

Yesterday we reported that Raptor Lake processors are largely a continuation of the Alder Lake generation using the same ingredients, despite a large increase in achieved clock speeds and some architectural changes (cache). This is even more true than we thought. It turns out that only the higher-tier K-series models are actually new chips. The lower end, including all 65W Core i5s, are recycling silicon from the Alder Lake generation. Read more “Cheaper Raptor Lake CPU will be just rebadged Alder Lake chips” »

125W/65W/35W Intel Raptor Lake specs leak, cheap i5-13400 too

Lots of info has already leaked about 125W Raptor Lake processors that Intel is abotu to launch on October 20 as the 13th-generation Core for desktop. The leaked specs were not complete, however. Now, we have a document that clarifies virtually everything – the clock speeds of little cores, details of various boost clocks for different numbers of active cores. And even specs of some 65W and 35W models. Read more “125W/65W/35W Intel Raptor Lake specs leak, cheap i5-13400 too” »

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.
