Context Before

Evidence

NVIDIA was aggressive on the CPU front, with Vera doubling performance over Grace by moving to a 3nm reticle-sized compute die and disaggregating the memory controllers and I/O into chiplets.

Context After

Core count increases from 72 to 88, with 91 cores printed on die to leave redundancy for yield improvement. These cores mark the return of NVIDIA’s custom ARM CPU designs, with the ‘Olympus’ core now supporting SMT multi-threading for a total of 176 processing threads.

② Atomic Claim

NVIDIA 在 CPU 方面採取積極設計：Vera 相較 Grace 效能加倍，透過 3nm reticle-sized compute die，並將 memory controllers 與 I/O 拆分到 chiplets。
