Nvidia's Ian Buck on Why GPUs Keep Winning: Blackwell Perf Up 4x Since Launch
firstadopter · x · 2026-10-15
Tae Kim's Key Context interviews Ian Buck, Nvidia's VP of hyperscale and HPC and inventor of CUDA, at the OCP Global Summit on why customers keep choosing GPUs over hyperscaler ASICs like Microsoft's Maia 300 and Amazon's next Trainium.
Key points:
- Buck's answer: every generation delivers more tokens across a larger, more diverse model set, plus better dollar-per-token economics—not just raw performance.
- He cites AgentX/InferenceX, MLPerf, and Artificial Analysis benchmarks showing continuous platform improvement: Blackwell performance has improved fourfold since launch.
- The interview also covers fitting 30% more GPUs into the same data center footprint and the dynamic between open and frontier models.
