AMD EPYC “Bergamo” 128-Core Processor Basato sullo stesso socket SP5 come “Genova”

AMD is launching two distinct classes of next-generation enterprise processors, the 4th Generation EPYC “Genova” with CPU core-counts up to 96-core/192-thread; and the new EPYC “Bergamo” with a massive 128-core/256-thread compute density. Pictures of the “Genova” MCM are Abbiamo sentito ieri come copie di, revealing twelve “Zen 4” CCDs built on 5 nm, and a new-generation sIOD (I/O die) that’s very likely built on 6 nm. The fiberglass substrate of “Genova” already looks crowded with twelve chiplets, making us wonder if AMD needed a larger package for “Bergamo.” Risulta, non lo fa.

In its latest Corporate presentation, AMD reiterated that “Begamo” will be based on the same SP5 (LGA-6096) package as “Genova.” This would mean that the company either made room for more CCDs, or the CCDs themselves are larger in size. AMD states that “Bergamo” CCDs are based on the “Erano le 4c” microarchitettura. Details about “Erano le 4c” are scarce, but from what we gather, it is a cloud-optimized variant of “Zen 4” probably with the entire ISA of “Zen 4,” and power characteristics suited for high-density cloud environments. These chiplets are built on the same TSMC N5 (5 nm EUV) process as the regular “Zen 4” CCD.
