Frequently asked
- Can A100 80GB run Gemma 2 9B?
- Yes. Gemma 2 9B needs ≈ 19.5 GB VRAM at fp16 and A100 80GB provides 80 GB. Expected throughput is 80 tokens/sec per GPU.
- How much VRAM does Gemma 2 9B use?
- About 19.5 GB at fp16, 6.2 GB at INT4 (for a 4K context, batch size 1). Longer contexts add to KV cache size; larger batches increase activations.
- What's the fastest way to run Gemma 2 9B on A100 80GB?
- Use a production inference engine like vLLM, SGLang, or TensorRT-LLM with paged attention — they cut KV cache 2–3× vs the naive estimate and batch multiple requests efficiently. For A100 80GB, enable Flash Attention 2.
- Where can I rent a A100 80GB?
- GPUniq aggregates live A100 80GB offers from verified providers. You can deploy an instance in about a minute and pay hourly with no commitment.
