Rubin, Vera CPU, networking, and complete-system competition intensify the inference race

Aivres’s Rubin and B300 displays and Google Cloud’s A5X plans signal ecosystem activity, not broad deployment; a Vera Rubin specification discrepancy remains unresolved. Cerebras’s reported wafer-scale advantage is workload- and concurrency-dependent and awaits independent validation. Tenstorrent and compiler alternatives add pressure, but performance, cost, software maturity, and deployment scale remain unproven.
