Intel Arc Pro B60 and GeForce RTX 3090 both have 24GB, but they are not interchangeable local-AI purchases. The B60 is a current Intel workstation path with a published 120–200W board-power range; the RTX 3090 is a 350W Ampere card whose practical value case often depends on used inventory and CUDA compatibility.
The capacity result is a tie
A 19.9GB Qwen2.5-32B Q4_K_M file leaves the same nominal 4.1GB before cache, workspace, display use and runtime overhead on either 24GB card. Q5_K_M leaves only 0.7GB and is not a safe fully resident target. Capacity does not answer which software stack will run the workload correctly or faster.
The real decision
- B60: verify the exact oneAPI/OpenVINO/SYCL or Vulkan path, partner board and application version.
- RTX 3090: prefer it when CUDA support is required, but inspect the exact used card, power system, temperatures, connector, repair history and return terms.
- Either: measure identical model, context, cache, backend conditions, memory placement, output correctness and wall energy.
