What fits in memory, on one GPU
| Workload | RTX 6000 Ada | RTX A6000 |
|---|---|---|
| LLM inference, 16-bit | ≈ 15B parameters | ≈ 15B parameters |
| LLM inference, 4-bit | ≈ 60B parameters | ≈ 60B parameters |
| Full training, mixed precision | ≈ 2B parameters | ≈ 2B parameters |
Cautious estimates counting 80% of memory for model weights; context length, batch size and framework change the real limit. Several GPUs together hold larger models.
RTX 6000 Ada vs RTX A6000: frequently asked questions
Which has more memory, the RTX 6000 Ada or the RTX A6000?
Both have 48 GB of GPU memory.
Which is faster for LLM inference, the RTX 6000 Ada or the RTX A6000?
Generating tokens is usually bound by memory bandwidth, and the RTX 6000 Ada has 1.3× the bandwidth of the RTX A6000. Memory size then decides which models fit. Measure your own model before a large run.
Can I rent the RTX 6000 Ada and the RTX A6000 by the hour?
Yes, when sellers list them on the EverXCloud spot exchange: you buy GPU hours at the live price from a prepaid balance in euros, US dollars or pounds. Prices are shown excluding tax and EverXCloud is the merchant of record for every rental.
