Frequently asked questions
What is the largest LLM that fits on a single A40 48GB?
At 8K context and batch 1, the largest models in our catalog that fit on an A40 48GB (48 GB) are: DeepSeek Coder V2 Lite (16B) at BF16; Qwen3.6 35B-A3B (35B) at FP8; CodeLlama 70B (70B) at 4-bit (AWQ). Larger models need tensor parallelism across several GPUs or lower-precision weights.
Can an A40 48GB run LLaMA 3.3 70B?
at BF16: needs 4× A40 48GB; at FP8: needs 2× A40 48GB; at 4-bit (AWQ): needs 2× A40 48GB. 8K context, batch 1, vLLM — the calculator sizes other contexts and concurrency.
Can an A40 48GB serve DeepSeek R1?
at BF16: does not fit within one 8-GPU node; at FP8: does not fit within one 8-GPU node; at 4-bit (AWQ): does not fit within one 8-GPU node. 8K context, batch 1, vLLM — the calculator sizes other contexts and concurrency.
How fast is an A40 48GB for LLM inference?
Single-stream decode for LLaMA 3.1 8B at FP8 is about 45 tokens/s on one A40 48GB; decode is bound by memory bandwidth (696 GB/s), so larger models run proportionally slower. Batching raises total throughput far above the single-stream figure.
How much does it cost to rent an A40 48GB?
For on-demand rental our catalog estimate is $0.35/hr. The $/1M tokens column above uses that price.
Methodology: every cell comes from the same engine as our GPU Lookup — weights, KV cache (including MLA latent and hybrid / sliding-window layers), activations and framework overhead per model architecture, decode speed from a calibrated memory-bandwidth roofline. Reference scenario: 8K context (4K for models with a shorter native window), batch 1, vLLM, fp16 KV cache. Fit bands: optimal 50–70% of VRAM, good 70–80%, tight 80–95%. Engineering estimates, not a guarantee — validate against your serving framework before buying hardware.
