What GPU do I need to run Qwen/Qwen2-57B-A14B?
57.4B parameters, published in BF16. View on Hugging Face
Set up Qwen2-57B-A14BQwen2-57B-A14B is published by Qwen on Hugging Face, with 10,176 downloads and 58 likes to date. It's a Qwen2MoeForCausalLM model built for text-generation, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision times a flat 1.2 overhead for activations and fragmentation. The KV-cache grows with context and is not in that factor; it is listed per model below where the architecture is published. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| BF16 | 106.9 GB | 128.3 GB | AMD MI300X | 1 | $2.63/hr |
| cheaper alt. | RTX A5000 | 6 | $1.06/hr | ||
| FP8 (quantized) | 53.5 GB | 64.2 GB | RTX PRO 6000 WS | 1 | $1.66/hr |
| cheaper alt. | RTX 4000 SFF Ada | 4 | $0.792/hr | ||
| INT4 (quantized) | 26.7 GB | 32.1 GB | RTX A6000 | 1 | $0.363/hr |
| cheaper alt. | RTX 3060 | 3 | $0.330/hr |
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 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run Qwen2-57B-A14B at its published (BF16) precision: 1× AMD MI300X, at $2.63/hr per GPU ($2.63/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Qwen2-57B-A14B: KV cache by context length
The KV cache is the memory the attention layers hold for every token of context, on top of the weights. It is not part of the flat 1.2x overhead in the table above, grows with context length and with every concurrent request, and is why a long-context deployment needs more VRAM than the table shows.
Grouped-query attention: every layer caches keys and values for a few shared KV heads. Cached per token: 57,344 bytes at 16-bit.
| Context | KV cache, one sequence |
|---|---|
| 4K | 0.22 GB |
| 32K | 1.8 GB |
| 128K | 7.0 GB |
Computed from the layer, head and window counts in the model's own configuration (Qwen/Qwen2-57B-A14B), at 16 bits per cached value. Each concurrent sequence needs its own cache, on top of the weights.
Qwen2-57B-A14B: common questions
Can Qwen2-57B-A14B run on a single GPU?
Yes, but not on a desktop card. At BF16 it needs 128.3 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest live single-card fit is a 192.0 GB AMD MI300X at $2.63/hr.
Does quantizing Qwen2-57B-A14B lower the GPU bill?
Yes. At BF16 the cheapest live fit is one AMD MI300X at $2.63/hr. At INT4 (quantized) it drops to one RTX A6000 at $0.363/hr, provided a quantized checkpoint exists for it.
