Intel Data Center GPU Max Subsystem vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

The Verdict

The Intel Data Center GPU Max Subsystem and the NVIDIA RTX PRO 4500 Blackwell Server target different segments of the server market, and the data reflects that split. The Intel part, built on the Ponte Vecchio chip, is a high-power, high-memory compute accelerator designed for massive parallel workloads that can use its 128 GB of HBM2e. The NVIDIA part, built on the GB203 chip, is a much more power-efficient server card that still delivers substantial compute throughput while drawing a fraction of the power. The database shows both cards sit at the 50th percentile among all GPUs, with an average benchmark score of 0 for each, meaning the recorded data does not currently rank one above the other in aggregate performance. The practical choice depends on the workload’s memory capacity needs versus power and density constraints.

For workloads that require enormous memory capacity, the Intel subsystem is the clear pick. Its 128 GB of HBM2e memory is four times the 32 GB of GDDR7 on the NVIDIA card. The Intel part also offers a memory bus width of 8192 bits versus 256 bits, and memory bandwidth of 3.21 TB/s versus 800.3 GB/s. For data-intensive operations such as large model inference or scientific simulations that exceed 32 GB, the NVIDIA card cannot hold the working set. The Intel card’s higher texture rate, 1,638.4 GTexel/s versus 792.1 GTexel/s, and its larger shading unit count, 16,384 versus 10,496, provide additional raw compute capacity in certain workloads.

The NVIDIA RTX PRO 4500 Blackwell Server is the better choice for environments where power efficiency and physical footprint matter. The NVIDIA card draws 165 W, while the Intel subsystem draws 2400 W. The NVIDIA card is single-slot, while the Intel card is dual-slot. The NVIDIA card also has a much lower suggested power supply, 450 W versus 2800 W. The NVIDIA card’s boost clock of 2415 MHz is substantially higher than the Intel card’s 1600 MHz, and its base clock of 1215 MHz exceeds the Intel card’s 900 MHz. The NVIDIA part also supports DirectX 12 Ultimate and Vulkan 1.4, while the Intel part supports DirectX 12 (12_1) with no Vulkan listed.
