Two models are 64-core, the third is 32-core
An insider published a document with the characteristics of three promising AMD CPUs of the Epyc Milan line – they should be released by the end of this year. The 7 nm manufacturing process will continue, but the architecture will change – Zen 3 will be replaced by Zen 3. Now, thanks to the efforts of the informant, it is possible to evaluate the specifications of the three models of the line.
64 cores with a frequency of up to 3.0 GHz. Three AMD Epyc Milan processors on Zen 3 architecture lit up on the Web
There are two 64-core models; they appear under the designations 100-000000114-07 and 100-000000114-09. 32-core – 100-000000117-03. Stepping A0 suggests that all three CPUs are just engineering samples. The chip layout used in the current Epyc has remained valid: the older models consist of eight chipsets (Core Complex Die, CCD) and one input/output core (I / O Die, IOD), the youngest is represented by four chipsets and also one input core output.
64-core models have twice as much L3 cache, but they also have higher TDP. Judging by the frequencies, Epyc Milan in this regard will not differ much from the current Epyc Rome; instead, the company will focus on improving productivity and energy efficiency by optimizing the architecture. However, while we are only talking about engineering samples, it is possible that AMD can pleasantly surprise with the frequency of serial Milan.
As for the insider who provided this data, he is usually well informed and not noticed in outright misinformation. For example, at the end of March, he correctly predicted the transfer of the GeForce GTX 1650 graphics card to GDDR6 memory ).
