Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
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. 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. L3 cache also received a 40% capacity bump to 162MB. Memory bus width doubled to 1024-bit and speed increased to 9600MT/s for 2.5x bandwidth, while maximum capacity tripled to 1.5TB with 8 SOCAMM modules. The NVLink-C2C to the Rubin GPUs also doubled in bandwidth to 1.8TB/s. PCIe6 and CXL3.1 are now supported as well. All this results in transistor count increasing 2.2x to 227 billion.
