Missing Clock Speeds for NVIDIA B300/GB300: Devs Attempt Reverse Engineering

StasBekman · x · 2026-08-08

Prominent ML engineer Stas Bekman pointed out on Twitter that official clock speed numbers for NVIDIA's upcoming Blackwell architecture chips, the B300 and GB300, are currently missing.

To obtain these critical hardware metrics, Bekman noted that he might have to reverse engineer the data using the published TFLOPS alongside the known clock speeds of the existing B200/GB200 models. This discussion originated from his open-source ML engineering manual on GitHub, highlighting the industry's intense focus on the parameters of next-gen compute cores.
