Intel Arc Pro B60 and GeForce RTX 4090 both offer 24GB of dedicated memory, but that capacity tie hides the purchase decision: a current Intel workstation path with a 120–200W board range versus mature CUDA support and a 450W GeForce flagship.
What stays equal
The official 19.9GB Qwen2.5-32B Q4_K_M file leaves a nominal 4.1GB before cache, workspace and other runtime allocations on either card. Q5_K_M leaves an unsafe 0.7GB; Q6_K and Q8_0 exceed both. A shared 24GB label does not prove equal compatibility or speed.
What changes
- B60: verify oneAPI/OpenVINO/SYCL or Vulkan support; consider professional drivers and its much lower published power range.
- RTX 4090: choose when CUDA maturity or measured NVIDIA-path performance justifies 450W reference power and its supporting system.
- Either: test identical artifacts, settings, placement and correctness before drawing a value conclusion.
