Frequently asked

Can RTX 6000 Ada run Llama 3.1 8B?
Yes. Llama 3.1 8B needs ≈ 19.5 GB VRAM at fp16 and RTX 6000 Ada provides 48 GB. Expected throughput is 105 tokens/sec per GPU.
How much VRAM does Llama 3.1 8B use?
About 19.5 GB at fp16, 6.0 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 Llama 3.1 8B on RTX 6000 Ada?
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 RTX 6000 Ada, enable Flash Attention 2.
Where can I rent a RTX 6000 Ada?
