NVIDIA B200 180GB vs NVIDIA B300 288GB for local LLMs
0 reports on the NVIDIA B200 180GB and 3 on the NVIDIA B300 288GB
Which is faster for local LLMs?
Nobody has reported the same model at the same quant on both cards yet, so there's no measured head-to-head. Memory bandwidth, which caps how fast a card can write, is about the same on both (8,000 GB/s on the NVIDIA B200 180GB, 8,000 on the NVIDIA B300 288GB). The estimates below compare them on the models people run most.
