Yes. Qwen3 8B fits in fast memory on RTX 3070 8GB at Q4_K_M (6.2 GB needed, 7.5 GB usable), about 52 tok/s (estimate).
Hardware: RTX 3070 8GB · Model: Qwen3 8B
RTX 3070 8GB has 8 GB of VRAM and 448 GB/s of memory bandwidth. RTX 3060 Ti 8GB has the same memory and bandwidth, so the fit numbers match; this page is RTX 3070 8GB. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 7.5 GB. Partial offload may also use 60% of that system RAM. Qwen3 8B (8.19B, Alibaba) at Q4_K_M is a 5.2 GB download and needs 6.2 GB with headroom for about 8k tokens.
