NVIDIA B200

NVIDIA’s data center GPU from the Blackwell generation, the successor to the H100.

• Memory size: 192 GB HBM3e
• Memory bandwidth: about 8,000 GB/s, roughly 4.5 times the RTX 5090
• Compute capability: sm_100, a different family from the 5090’s sm_120. That’s why the fastest kernels written for one don’t always run on the other.
