Two so-called processor engineering samples from AMD appeared in the benchmark database of the decentralized computing project MilkyWay @ home. The pre-production models apparently belong to AMD’s upcoming desktop series Raphael alias Ryzen 7000: Like the Ryzen 9 5950X and Ryzen 7 5800X, they use 16 and 8 CPU cores, respectively, but have doubled level 2 caches.
the The Twitter member “BenchLeaks” found entries. MilkyWay @ home shows the 16- and the 8-core of the previously unknown AMD family 25 Model 96. For comparison: the previous Ryzen 5000 CPUs from the Vermeer desktop series belong to the 25 Model 33 family, the mobile Ryzen 5000 combination processors (Cezanne) such as the Ryzen 9 5900HX belong to the 25 Model 80 family.
Doubled level 2 cache
The “CPU cache” specified by MilkyWay @ home represents the level 2 cache, as a comparison of processors already presented shows. All AMD CPUs with Zen architecture since the Ryzen 1000 series have so far used 512 KByte level 2 cache per CPU core – there were only changes to the structure and capacity of the level 3 cache.
According to the database, the new models use 1 Mbyte L2 cache per CPU core. Such a big change speaks in favor of a new generation of architecture and thus Zen 4. At the CES trade fair 2022, AMD boss Lisa Su already stated that Ryzen 7000 samples are running in their own laboratories – the new findings substantiate this statement. AMD has the Raphael CPUs manufactured by TSMC with 5 nanometer structures. Also included are DDR5 RAM, PCI Express 5.0 and the new AM5 platform.
Performance not comparable
However, the performance results are useless: previous models such as the Ryzen 9 5950X are significantly faster in the BOINC system (Berkeley Open Infrastructure for Network Computing) that MilkyWay @ home uses. This could be due to low clock frequencies or unfinished drivers. The presentation will not take place until autumn 2022.
Meanwhile, Intel took a similar path with the current generation of processors, Alder Lake, aka Core i-12000: While the predecessor Rocket Lake (Core i-11000) was content with 512 KByte Level 2 cache per core, it is now 1.25 each Mbyte. The predecessor Comet Lake (Core i-10000) even only used 256 KB per CPU core.
