NVIDIA RTX PRO 4500 Blackwell Server vs NVIDIA RTX PRO 5000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data contains benchmark results for the NVIDIA RTX PRO 5000 Blackwell, while the NVIDIA RTX PRO 4500 Blackwell Server has no benchmark entries in the database. This asymmetry means a direct numerical comparison between the two cards is not possible from the available measurements. The RTX PRO 5000 Blackwell delivers an average benchmark score of 182,109 across three tests: 3DMark Steel Nomad DX12 at 9,579.5, Geekbench OpenCL at 254,116, and Geekbench Vulkan at 282,631. These results place it at the 98th percentile among all GPUs in the database, indicating top-tier performance. The RTX PRO 4500 Blackwell Server, with a percentile of 50 and an average score of 0, represents a midpoint positioning in the overall distribution, but the absence of actual test scores limits any direct head-to-head analysis.

The RTX PRO 5000 Blackwell sits within a tight competitive cluster. Its average score of 182,109 is 0.9% below the NVIDIA A100 SXM4 80 GB (183,725), 1.4% below the NVIDIA RTX 5000 Ada Generation (184,664), and 2.7% below the NVIDIA A100 SXM4 40 GB (187,147). Against the NVIDIA GeForce RTX 4090 D (178,050), the RTX PRO 5000 Blackwell is 2.3% ahead. These deltas are small, suggesting that the RTX PRO 5000 Blackwell performs within the same general band as these established accelerators. The 98th percentile ranking confirms that its performance is near the top of the database, even if it does not lead every comparison. The RTX PRO 4500 Blackwell Server lacks such reference points, so its placement cannot be validated through measured scores.

Given the lack of head-to-head benchmark data, the analysis must rely on architectural and specification differences to infer relative capabilities. The RTX PRO 5000 Blackwell shows a clear advantage in raw compute metrics, but the RTX PRO 4500 Blackwell Server offers a lower power envelope, which may influence deployment decisions in dense server environments.

Where Each One Wins

The RTX PRO 5000 Blackwell wins on every compute and memory metric. Its FP32 throughput of 66.94 TFLOPS surpasses the RTX PRO 4500 Blackwell Server's 50.70 TFLOPS by a substantial margin. Memory bandwidth of 1.34 TB/s versus 800.3 GB/s gives the RTX PRO 5000 Blackwell a clear advantage in bandwidth-bound workloads. The larger 48 GB memory capacity also supports larger datasets and models compared to 32 GB. The RTX PRO 5000 Blackwell has more shading units, TMUs, ROPs, RT cores, and tensor cores, which directly translates to higher pixel and texture rates. Its 98th percentile ranking among all GPUs, supported by an average benchmark score of 182,109, confirms its high-end positioning.

The RTX PRO 4500 Blackwell Server wins on power efficiency and form factor. Its 165 W TDP is less than half the 300 W TDP of the RTX PRO 5000 Blackwell, and its suggested power supply of 450 W is far below the 700 W requirement. The single-slot design allows for denser server installations compared to the dual-slot RTX PRO 5000 Blackwell. The RTX PRO 4500 Blackwell Server also has a higher boost clock (2415 MHz versus 2377 MHz), which may help in lightly threaded scenarios, though its lower base clock (1215 MHz versus 1740 MHz) suggests a different power management strategy. The absence of display outputs on the RTX PRO 4500 Blackwell Server indicates it is intended strictly for compute tasks, freeing up server resources.

The Verdict

The data points to a clear separation of roles. The RTX PRO 5000 Blackwell is the higher-performing card across all measured specs, with a 98th percentile ranking and an average benchmark score of 182,109. It is suitable for workloads that demand maximum FP32 throughput, large memory capacity, and high bandwidth. The RTX PRO 4500 Blackwell Server, with its 50th percentile placement and no recorded benchmarks, appears positioned as a mid-tier server option that prioritizes power efficiency and density. Its 165 W TDP and single-slot design make it a fit for environments where space and power are constrained.

For users who need the highest compute capability and can accommodate a dual-slot, 300 W card, the RTX PRO 5000 Blackwell is the clear choice based on the recorded data. Its performance relative to rivals, such as being 2.3% ahead of the GeForce RTX 4090 D and within 1.4% of the RTX 5000 Ada Generation, confirms it is a competitive high-end option. For server deployments that require minimal power draw and single-slot density, the RTX PRO 4500 Blackwell Server offers a lower-power alternative, though its performance cannot be quantified from the database. The RTX PRO 5000 Blackwell also includes display outputs, making it more versatile for workstation use, while the RTX PRO 4500 Blackwell Server is compute-only. The release dates differ by roughly one year, with the RTX PRO 5000 Blackwell launching first.
