Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 50.9 GB, but this setup only exposes 24.0 GB of usable VRAM.
Add more VRAM headroom
The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.

No, Nemotron 70B requires more memory than RX 7900 XTX 24GB provides.
Nemotron 70B (70B parameters) requires approximately 50.9 GB of memory with Q4_K_M quantization.
The recommended quantization for Nemotron 70B is Q4_K_M, which balances quality and memory efficiency.
On RX 7900 XTX 24GB, Nemotron 70B achieves approximately 2.7 tokens per second decode speed with a time-to-first-token of 71322ms using Q4_K_M quantization.
For coding workloads, Nemotron 70B on RX 7900 XTX 24GB receives a F grade with 2.7 tok/s and 4K context.
On RX 7900 XTX 24GB, Nemotron 70B can safely use up to 4K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Add more VRAM headroom. The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
