NVIDIA’s Vera Whitepaper Has a Thread Loose
Chips and Cheese finds NVIDIA’s first in-house server CPU, Vera, genuinely strong hardware but a much weaker competitive narrative. The 88-core Olympus Arm design has a 10-wide front end, value prediction, graph prefetching, large caches, and up to 1.2 TB/s of LPDDR5X bandwidth; early independent tests suggest formidable per-core performance.
The whitepaper’s comparisons are less convincing: it caricatures conventional SMT, treats an optional 32-node EPYC NUMA layout as the norm, calls ordinary SPEC programs “agentic benchmarks,” compares undefined cross-ISA counters, and presents an RL chart without enough methodology to reproduce it. The authors’ own Turin measurements also reduce NVIDIA’s claimed memory-bandwidth lead from nearly 3× to roughly 1.9×. Readers broadly agreed that open, unrestricted production testing should decide the question.
