What is B200?

The B200 is a GPU model referenced in discussions about AI hardware performance and availability. Sources track its computational capabilities, market supply dynamics, and reliability under stress.

• Dec 2025 - Zain Asgar said that with GPUs like the B40 or B200, “you’ll start seeing much more significant gains,” noting 20-40% performance improvements in many cases.
• Apr 2026 - Jack Farley said that “GPU availability for B200s has collapsed,” with H100s close behind.
• May 2026 - Reiner Pope noted that historically, up until B100 or B200, halving bit precision doubled FLOP count, but due to quadratic scaling, the ratio is slightly wrong, implying even larger speedups.
• Aug 2026 - Philip Johnston said that his team knows where an H100, B200, and H200 will fail when blasted with high velocity protons and heavy ions, indicating unique knowledge of chip vulnerabilities.
