Question 1

How much VRAM does Llama-3_3-Nemotron-Super-49B-v1 need?

Accepted Answer

Llama-3_3-Nemotron-Super-49B-v1 (49.9B) requires approximately 111.46175537109374 GB of VRAM at full precision (FP16), 55.7 GB at 8-bit quantization (Q8), and 27.9 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run Llama-3_3-Nemotron-Super-49B-v1?

Accepted Answer

We have 9 compatible GPUs indexed for Llama-3_3-Nemotron-Super-49B-v1, including H200 SXM, MI300X, MI350X, B200, B100 and 4 more. Compatibility is determined by whether the GPU's VRAM can fit the model's memory footprint, potentially using quantization to reduce memory usage.

Question 3

What is the cheapest GPU to run Llama-3_3-Nemotron-Super-49B-v1?

Accepted Answer

The cheapest GPU to run Llama-3_3-Nemotron-Super-49B-v1 in the cloud is the H200 SXM at $2.35/hr. Other affordable options include MI300X ($2.39/hr) and MI350X ($5.49/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Llama-3_3-Nemotron-Super-49B-v1 run on consumer hardware?

Accepted Answer

Llama-3_3-Nemotron-Super-49B-v1 requires approximately 111.46175537109374 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 27.9 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Llama-3_3-Nemotron-Super-49B-v1 requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Llama-3_3-Nemotron-Super-49B-v1?

Accepted Answer

Llama-3_3-Nemotron-Super-49B-v1 supports the following quantization levels: FP16 (full precision): ~111.46175537109374 GB, Q8 (8-bit): ~55.7 GB, Q6 (6-bit): ~41.8 GB, Q4 (4-bit): ~27.9 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression.
