AMD EPYC series processor specifications in X3D package are exposed, with L3 cache capacity up to 768MB

AMD officially released the third-generation EPYC (7003 series) processor code-named Milan in March of this year, and then at this year’s Computex 2021 keynote speech, AMD CEO Dr. Lisa Su demonstrated the Zen 3 architecture desktop processor with 3D vertical cache (3D V-Cache) technology. This technology can bring an additional 64MB 7nm SRAM cache for each CCD, and the Zen 3 architecture Ryzen series processor with a 3D vertical cache will be put into production later this year.

It is understood that AMD will also do this on the EPYC series and Ryzen Threadripper series processors. The EPYC processor code-named Milan-X is a product that uses 3D vertical cache technology. Prior to this, suppliers have released the models and OPN codes of individual processors. Recently, Twitter user @ExecuFix further revealed the specifications of these EPYC processors.

EPYC 7773X processor, its OPN code is 100-000000504, has 64 cores and 128 threads, TDP is 280W. In addition to its own 256MB, the L3 cache also has a stacked 512MB, with a total capacity of 768MB, which is multiplied by three on the original basis. According to the price announced by B2B retailer Zones, the price of the EPYC 7773X processor is as high as $10,746.99.

AMD still has not disclosed the EPYC processor code-named Milan-X, and the final release time is uncertain.
