That means the NVIDIA card achieves roughly 0.25 TFLOPS per watt, while the Intel card achieves about 0.02 TFLOPS per watt. The NVIDIA card’s 550 W suggested PSU is 5 times lower than the Intel card’s 2800 W requirement.

Where Each One Wins

The Intel Data Center GPU Max Subsystem wins in scenarios that demand extreme memory capacity and bandwidth. Its 128 GB HBM2e pool with 3.21 TB/s bandwidth suits workloads where entire datasets must reside in GPU memory. The 8192-bit bus provides the highest memory throughput in the comparison. Its 52.43 TFLOPS FP32 also edges past the NVIDIA card, and its 1,638.4 GTexel/s texture rate doubles the NVIDIA card’s throughput. The 128 RT cores outnumber the NVIDIA card’s 82 RT cores. This card targets compute density in a server context, reflected by its 2400 W TDP and lack of display outputs.

The NVIDIA RTX PRO 4500 Blackwell Workstation wins in workstation and graphics-centric tasks. It is the only card with display outputs, offering 4x DisplayPort 2.1b. Its 112 ROPs and 269.6 GPixel/s pixel rate enable traditional rasterization, which the Intel card cannot perform with 0 ROPs. The NVIDIA card’s 328 tensor cores provide dedicated AI acceleration. Its DirectX 12 Ultimate (12_2) and Vulkan 1.4 support cover modern graphics APIs, while the Intel card lacks Vulkan and only reaches DirectX 12 (12_1). The 200 W power draw makes it feasible for standard workstation power supplies, and the 550 W suggested PSU fits typical desktop configurations. Higher clock speeds (1635 MHz base, 2407 MHz boost) also give the NVIDIA card an advantage in latency-sensitive tasks.

Both cards share PCIe 5.0 x16 connectivity, dual-slot form factors, and 267 mm length, but their intended environments differ completely. The Intel card requires a 2800 W power supply and has no display outputs, indicating a rack-mounted compute accelerator. The NVIDIA card fits into a workstation chassis with display connectivity and modest power needs. The data shows no overlap in their primary use cases: the Intel card prioritizes memory bandwidth and compute density, while the NVIDIA card prioritizes graphics features, efficiency, and workstation practicality.
