AMD introduced its first server processors with 3D V-Cache technology called Epyc Milan-X. The next generation of Zen 3 processors uses the Zen 3 core architecture and has improved their performance in various areas. The highest member of this family has 64 nuclei and 128 disciplines.
We've been seeing reports of AMD's Milan-X processors for a long time, and now we know what frequency and amount of crashes we're dealing with in these processors that use V-Cache 3D vertical chiplet technology.
EPYCMilan-X server processors include 4 models . The highest model is called EPYC 7773X, which is equipped with 64 cores and 128 strands. The next processor, the EPYC 7573X, uses 32 cores and 128 threads. Subsequent models with the letters EPYC 7473X and EPYC 7373X have 24 and 16 cores and 48 and 32 strings, respectively.
The thermal design power of the highest model, the EPYC 7773X, reaches 280 watts and has a base frequency of 2.2 GHz. Its boost frequency is 3.5 GHz and it has 768 MB of cache, which includes 256 GB of standard L3 cache and 512 MB of L3 SRAM stack cache. Therefore, each Zen 3 architecture CCD is equipped with 64 MB of L3 cache, which is three times the current EPYC Milan processors.
The next processor, the EPYC 7573X, also has a thermal design capacity of 280 watts. Its base and boost frequencies are 2.8 and 3.6 GHz, respectively, and its total cache is 768 MB. The EPYC 7473X processor has a base frequency of 2.8 GHz and a boost frequency of 3.7 GHz, and its thermal design power reaches 240 watts. The latest processor with a thermal design power of 240 watts, a base frequency of 3.55 GHz and a boost frequency of 3.8 GHz along with 768 MB of cache are available to buyers.
A 3D V-Cache stack contains 64 MB of L3 cache, which adds up to 32 MB of L3 cache for a total of 96 MB per CCD. Introducing the new processors, AMD announced a 66 percent improvement over the previous generation.
The EPYC Milan-X processors will be available in the first quarter of 2022 and will be available through companies such as Dell, Cisco and Lenovo.
