NVIDIA A10G vs NVIDIA RTX 4090 for local LLMs

0 reports on the NVIDIA A10G and 37 on the NVIDIA RTX 4090

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 1.7x higher on the NVIDIA RTX 4090 (600 GB/s on the NVIDIA A10G, 1,008 on the NVIDIA RTX 4090). The estimates below compare them on the models people run most.
