ThunderKittens Unlocks 2× Faster GEMM & Attention on Nvidia Blackwell GPUs
ThunderKittens now ships BF16/FP8 GEMM and forward/backward attention kernels optimized for Nvidia’s Blackwell B200. The kernels hit cuBLAS/cuDNN performance on B200 and are up to two‑times faster than the same ops on H100, thanks to new 5th‑gen tensor cores, Tensor Memory and CTA‑pair data‑flow tricks. Developers can squeeze top‑line throughput from Blackwell without low‑level CUDA gymnastics.
