Question 1

How much VRAM does granite-20b-code-instruct-8k need?

Accepted Answer

granite-20b-code-instruct-8k (20.1B) requires approximately 44.853224945068355 GB of VRAM at full precision (FP16), 22.4 GB at 8-bit quantization (Q8), and 11.2 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 granite-20b-code-instruct-8k?

Accepted Answer

We have 10 compatible GPUs indexed for granite-20b-code-instruct-8k, including A40, L40S, L40, RTX A6000, A100 80GB PCIe 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 granite-20b-code-instruct-8k?

Accepted Answer

The cheapest GPU to run granite-20b-code-instruct-8k in the cloud is the A40 at $0.44/hr. Other affordable options include L40S ($0.60/hr) and L40 ($0.82/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can granite-20b-code-instruct-8k run on consumer hardware?

Accepted Answer

Yes, granite-20b-code-instruct-8k can run on consumer GPUs like the RTX A6000 (48 GB VRAM) at full precision (FP16). Other compatible consumer GPUs include RTX Pro 6000 Blackwell.

Question 5

What quantization options are available for granite-20b-code-instruct-8k?

Accepted Answer

granite-20b-code-instruct-8k supports the following quantization levels: FP16 (full precision): ~44.853224945068355 GB, Q8 (8-bit): ~22.4 GB, Q6 (6-bit): ~16.8 GB, Q4 (4-bit): ~11.2 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.
