Question 1

How much VRAM does internlm2-math-plus-20b need?

Accepted Answer

internlm2-math-plus-20b (19.9B) requires approximately 44.39312896728516 GB of VRAM at full precision (FP16), 22.2 GB at 8-bit quantization (Q8), and 11.1 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 internlm2-math-plus-20b?

Accepted Answer

We have 10 compatible GPUs indexed for internlm2-math-plus-20b, including A40, L40S, L40, A100 80GB PCIe, A100 80GB and 5 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 internlm2-math-plus-20b?

Accepted Answer

The cheapest GPU to run internlm2-math-plus-20b in the cloud is the A40 at $0.44/hr. Other affordable options include L40S ($0.60/hr) and L40 ($0.99/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can internlm2-math-plus-20b run on consumer hardware?

Accepted Answer

Yes, internlm2-math-plus-20b can run on consumer GPUs like the RTX Pro 6000 Blackwell (96 GB VRAM) at full precision (FP16).

Question 5

What quantization options are available for internlm2-math-plus-20b?

Accepted Answer

internlm2-math-plus-20b supports the following quantization levels: FP16 (full precision): ~44.39312896728516 GB, Q8 (8-bit): ~22.2 GB, Q6 (6-bit): ~16.6 GB, Q4 (4-bit): ~11.1 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.
