Can I run Qwen3 8B on Nvidia GeForce GTX 1070 (8GB)?
Yes. Qwen3 8B runs on Nvidia GeForce GTX 1070 (8GB) at Q4_K_M (~6.5 GB of ~7 GB usable).
Fits at Q4_K_M (~6.5 GB of ~7 GB usable) but with little headroom. Close other apps; a smaller context frees a few hundred MB.
That figure is at a 4k context and moves about ±15% as context length changes. Nvidia GeForce GTX 1070 (8GB) leaves ~0.5 GB of headroom.

Running cost · estimate

- Pays for itself after
- ~1,223M tok
At ~$0.15/kWh and the estimated ~33 tok/s, a million generated tokens costs about $0.19 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$379 Nvidia GeForce GTX 1070 (8GB) pays for itself after roughly 1,223 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ
Can Nvidia GeForce GTX 1070 (8GB) run Qwen3 8B?
Yes. Qwen3 8B runs on Nvidia GeForce GTX 1070 (8GB) at Q4_K_M (~6.5 GB of ~7 GB usable).
How much memory does Qwen3 8B need?
It is a tight fit on Nvidia GeForce GTX 1070 (8GB). At Q4_K_M the weights are ~5.03 GB; with KV cache and runtime overhead, budget ~6.5 GB at a 4k context.
What is the best tool to run Qwen3 8B on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
