What GPU do I need to run nvidia/Qwen3-8B-FP8?
8.2B parameters, published in F8_E4M3. View on Hugging Face
Qwen3-8B-FP8 is published by nvidia on Hugging Face, with 468,643 downloads and 6 likes to date. It's a Qwen3ForCausalLM model built for text-generation, published natively in F8_E4M3.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for KV-cache, activations, and fragmentation. Full formula and assumptions: methodology.
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 caveat: requires a quantized checkpoint actually published for this model — check its Hugging Face page before relying on this row.
Cheapest way to run Qwen3-8B-FP8 at its published (F8_E4M3) precision: 1× RTX 4070 Super on simplepod, at $0.090/hr per GPU ($0.090/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
