Can the Arc Pro B60 run Qwen2.5 72B?
No. Qwen2.5 72B needs about 41.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the Arc Pro B60 has 24 GB, so it won't fit without offloading layers to system RAM, which is far slower.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 40 GB | 41.8 GB | Too big | - |
| Q5_K_M | 48 GB | 49.8 GB | Too big | - |
| Q8_0 | 78 GB | 79.8 GB | Too big | - |
| FP16 | 144 GB | 145.8 GB | Too big | - |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the Arc Pro B60's 456 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the Arc Pro B60 run Qwen2.5 72B?
No. Qwen2.5 72B needs about 41.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the Arc Pro B60 has 24 GB, so it won't fit without offloading layers to system RAM, which is far slower.
How much VRAM does Qwen2.5 72B need?
About 40 GB of weights at Q4_K_M, 78 GB at Q8_0 and 144 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen2.5 72B on the Arc Pro B60?
It doesn't fit in the Arc Pro B60's memory, so speed depends on how many layers you offload to system RAM - typically single-digit tokens per second or lower.
