217 reports on the NVIDIA RTX 3090 and 2 on the NVIDIA T1000 8GB

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 5.8x higher on the NVIDIA RTX 3090 (936 GB/s on the NVIDIA RTX 3090, 160 on the NVIDIA T1000 8GB). The estimates below compare them on the models people run most.
