Just an engineering sample The first tests and characteristics of the 60-core Intel Xeon Platinum 8580 processor have appeared on the Internet. We are talking about an engineering sample (ES2) of a processor from the Emerald Rapids line, which will be presented on December 14, and will hit the market next year. [caption id="attachment_58593" align="aligncenter" width="780"] Xeon Platinum 8580[/caption] These processors will replace the current Sapphire Rapids, offering a new architecture (Raptor Cove), but maintaining the Intel 7 process technology. The latter is the reason why the maximum number of cores will remain unchanged. Xeon Platinum 8580 appeared on the Internet [caption id="attachment_58594" align="aligncenter" width="780"] Xeon Platinum 8580[/caption] Each of the 60 processor cores has 2 MB of L2 cache, so the CPU has 120 MB of L2 cache in total. The third-level cache memory reaches an impressive 420 MB. However, Intel's brainchild is very far from the AMD Epyc Genoa-X line with its 1152 MB cache. It’s not worth focusing on tests yet, since this is an engineering sample.

But only server ones Despite the fact that there is still quite a bit of information on the Internet about the AMD Zen 5 architecture and products based on it, today we have received quite detailed data about CPUs based on Zen 6. [caption id="attachment_85418" align="aligncenter" width="780"] AMD[/caption] The information concerns mainly server CPUs, but it is still important, because some things can be implemented in consumer ones. [caption id="attachment_85419" align="aligncenter" width="780"] AMD[/caption] The author of the Moore's Law Is Dead channel obtained data on Epyc-E server processors, which are intended for telecommunications and peripheral systems. Such CPUs will only have up to 64 cores, but the “larger” Epyc will, of course, have more cores. AMD will pack 32 processor cores into one chiplet. [caption id="attachment_85420" align="aligncenter" width="780"] AMD[/caption] In this case, what interests us most is that Epyc-E will have one chiplet with 32 cores! Let us remember that in almost all AMD processors the chiplet contains eight cores, and only Epyc Bergamo with small Zen 4C cores has chiplets with 16 cores. As you can see, by the time Zen 6 is released, AMD will be able to pack 32 cores per chiplet. This obviously won’t affect consumer Ryzen, but perhaps by that time they will switch to a package of 16 cores per chiplet. Additionally, the 32-chip configuration could allow AMD to easily build 256-core processors. This could already be CPU Venice in SP7 version. https://youtu.be/qpzTmKjaIMU Also, a large number of cores in one chiplet allows AMD to place additional chiplets in the processor without any processor cores at all. FPGAs or other specialized chiplets can be implemented in this way.

Based on RISC-V cores The Chinese company SophGo is developing a processor based on the RISC-V architecture, using solutions from the American company SiFive. [caption id="attachment_82463" align="aligncenter" width="600"] 64-core processor[/caption] The processor, called the SG2380, has 16 SiFive P670 cores, each roughly equivalent in performance to a Cortex-A77, a SiFive X280 AI/ML accelerator, and an AXT-16-512 GPU from Imagination Technologies. The Chinese company SophGo is creating a 64-core processor based on American SiFive technologies In addition, SophGo has already announced the SG2044 SoC, which will be released next year. It will already offer 64 processor cores, support for PCIe 5.0 and LPDDR5x. Both solutions will be produced using the 12 nm process technology, apparently at the facilities of the Chinese SMIC, since initially the SiFive cores, which SophGo uses, are focused on much more modern technology processes. Thus, SophGo is not subject to the latest US sanctions, since they do not apply to the RISC-V architecture. The popularity of this architecture has been growing recently, and American sanctions may make RISC-V an even more popular solution specifically in China.

It has 80 Arm cores While Chinese video cards are very far from modern solutions from AMD, Nvidia, and Intel, Chinese processors are developing at a very impressive pace. Phytium has shown off its new processor, which is capable of competing with AMD CPUs based on the Zen 3 architecture. [caption id="attachment_71250" align="aligncenter" width="780"] AMD Epyc on Zen 3[/caption] Chinese Arm processor capable of competing with 24-core AMD Epyc on Zen 3. More precisely, the company compares its FTC870 with the server AMD Epyc 7443. Let us recall that the latter has 24 cores, a TDP of 200 W, and operates at frequencies up to 4 GHz. The FTC870, in turn, is based on the Arm architecture and operates at a frequency of only 3 GHz. The new product has 80 cores and 64 MB of third-level cache. There is also an eight-channel DDR5-4800 controller and 64 PCIe 5.0 lanes. [caption id="attachment_71251" align="aligncenter" width="780"] AMD Epyc on Zen 3[/caption] Interestingly, the company planned to release such a CPU back in 2021, but due to US sanctions the process has slowed down, so such CPUs will only be released now.
