GPUs for on-prem AI / NVIDIA
NVIDIA RTX A6000 48GB for LLMs
Ampere workstation card; 48GB at 300W makes 2-4 card workstations practical for 70B at 4-bit. No FP8. NVIDIA lists 309.7 TFLOPS tensor with sparsity, halved here. Price is an indicative 2026 street range for one unit, not a quote.

Questions
What is the largest model that fits on one NVIDIA RTX A6000 48GB?
Of the models we track, Llama 3.3 70B Instruct (70B) fits on a single 48 GB card in 4-bit with one user at 8K context. More users or longer context need memory for the KV cache, so leave headroom.
How fast is NVIDIA RTX A6000 48GB for LLM inference?
Generation speed is mostly set by memory bandwidth: 768 GB/s here. Each token reads the active weights once, so a model with 8 GB of active weights tops out near 96 tokens per second per stream before efficiency losses; batching many users raises total throughput.
Is NVIDIA RTX A6000 48GB a good choice for on-prem AI?
Ampere workstation card; 48GB at 300W makes 2-4 card workstations practical for 70B at 4-bit. No FP8. NVIDIA lists 309.7 TFLOPS tensor with sparsity, halved here. Price is an indicative 2026 street range for one unit, not a quote.
