Architecture Differences

The two NVIDIA server parts come from different architectural generations. The H200 NVL uses the GH100 chip built on the Hopper architecture, belonging to the Server Hopper (Hxx) generation. The RTX PRO 4500 Blackwell Server uses the GB203 chip on the Blackwell 2.0 architecture, belonging to the Server Blackwell (Bxx) generation. Both are fabricated by TSMC on a 5 nm process node, but the transistor counts differ substantially. The GH100 packs 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3M per mm². The GB203 contains 45,600 million transistors on a 378 mm² die, producing a higher density of 120.6M per mm².

The shading unit counts also diverge. The H200 NVL has 16,896 shading units, 528 TMUs, and 24 ROPs. The RTX PRO 4500 Blackwell Server has 10,496 shading units, 328 TMUs, and 112 ROPs. The H200 NVL includes 528 tensor cores, but its RT core count is not recorded. The RTX PRO 4500 Blackwell Server includes 82 RT cores and 328 tensor cores. The H200 NVL lists N/A for DirectX, OpenGL, and Vulkan APIs, reflecting its compute-oriented design. The RTX PRO 4500 Blackwell Server lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, indicating broader graphics API support.

Memory architecture differs sharply. The H200 NVL uses 141 GB of HBM3e with a 6144-bit bus and 4.89 TB/s bandwidth. The RTX PRO 4500 Blackwell Server uses 32 GB of GDDR7 with a 256-bit bus and 800.3 GB/s bandwidth. The H200 NVL's memory clock is 1593 MHz with 6.4 Gbps effective transfer. The RTX PRO 4500's memory clock is 1563 MHz with 25 Gbps effective transfer. Clock behavior also differs: the H200 NVL runs at a 1365 MHz base and 1785 MHz boost, while the RTX PRO 4500 runs at 1215 MHz base and 2415 MHz boost.

The physical specifications show the H200 NVL as a dual-slot card with an 8-pin EPS power connector and a 1000 W suggested PSU. The RTX PRO 4500 Blackwell Server is a single-slot card with a 1x 16-pin power connector and a 450 W suggested PSU. Both share the same length (267 mm, 10.5 inches) and height (111 mm, 4.4 inches), but the RTX PRO 4500 adds a recorded width of 40 mm (1.6 inches), while the H200 NVL's width is not listed. Neither card has display outputs. The H200 NVL has a TDP of 600 W, while the RTX PRO 4500 has a TDP of 165 W.

The H200 NVL was released on November 17, 2024, with its predecessor listed as Server Ada and its successor as Server Blackwell. The RTX PRO 4500 Blackwell Server has a release date of March 16, 2026, with its predecessor listed as Server Hopper and its successor as Server Rubin. The H200 NVL's production status is Active, and the RTX PRO 4500's production status is also Active.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries between the H200 NVL and the RTX PRO 4500 Blackwell Server. The wins count for each side is zero. The RTX PRO 4500 has no benchmark scores at all in the database. Its average benchmark score is 0, and its percentile versus all GPUs is 50. The H200 NVL, by contrast, has one recorded Geekbench OpenCL score of 334,891, and its percentile versus all GPUs is 100.

The H200 NVL's score can be interpreted through its nearest rivals. It trails the NVIDIA B200 by 3.1%, as the B200 averages 345,482. It leads the AMD Instinct MI300X by 5.3%, with the MI300X averaging 317,994. It sits 9.4% behind the NVIDIA B300 SXM6 AC, which averages 369,831. It is 13.2% ahead of the NVIDIA L40S, which averages 295,763. These deltas place the H200 NVL in a competitive position within the high-end server GPU tier.

Because the RTX PRO 4500 Blackwell Server has no recorded benchmark data, a direct numerical comparison between the two cards cannot be performed from the database. The data indicates a substantial difference in shading unit count: the H200 NVL has 16,896 shading units versus 10,496 for the RTX PRO 4500. The texture rate favors the H200 NVL at 942.5 GTexel/s versus 792.1 GTexel/s for the RTX PRO 4500. The pixel rate, however, favors the RTX PRO 4500 at 270.5 GPixel/s versus 42.84 GPixel/s for the H200 NVL. The FP32 compute figures show 60.32 TFLOPS for the H200 NVL and 50.70 TFLOPS for the RTX PRO 4500. The FP16 figures show 120.6 TFLOPS (2:1) for the H200 NVL and 50.70 TFLOPS (1:1) for the RTX PRO 4500.

The memory bandwidth gap is wide. The H200 NVL delivers 4.89 TB/s, while the RTX PRO 4500 delivers 800.3 GB/s. Memory capacity also differs by a large margin: 141 GB versus 32 GB. The H200 NVL's 6144-bit bus width versus the RTX PRO 4500's 256-bit bus width explains part of that bandwidth difference. The effective memory transfer rate is higher for the RTX PRO 4500 at 25 Gbps versus 6.4 Gbps for the H200 NVL, but the H200 NVL compensates with a much wider bus and more memory channels.

The Verdict

The data shows two NVIDIA server accelerators with distinct roles. The H200 NVL is a high-capacity, high-bandwidth compute part. Its 141 GB of HBM3e memory, 4.89 TB/s bandwidth, and 16,896 shading units position it for workloads that demand large memory footprints and heavy parallel compute. Its 60.32 TFLOPS FP32 and 120.6 TFLOPS FP16 (2:1) figures place it above the RTX PRO 4500 in raw compute throughput. The H200 NVL's 600 W TDP and dual-slot design indicate a power-hungry accelerator for dense server environments. Its Geekbench OpenCL score of 334,891 sits within 3.1% of the B200 and ahead of the MI300X by 5.3%, confirming competitive standing among flagship server accelerators.

The RTX PRO 4500 Blackwell Server is a lower-power, single-slot part. Its 165 W TDP, 450 W suggested PSU, and single-slot form factor make it a more compact option. Its 2415 MHz boost clock is substantially higher than the H200 NVL's 1785 MHz, but its 10,496 shading units and 50.70 TFLOPS FP32 are lower. Its 32 GB GDDR7 memory with 800.3 GB/s bandwidth is a fraction of the H200 NVL's capacity and bandwidth. The RTX PRO 4500 includes RT cores and full graphics API support, while the H200 NVL lists N/A for all graphics APIs. The RTX PRO 4500's pixel rate of 270.5 GPixel/s is far higher than the H200 NVL's 42.84 GPixel/s, suggesting different workload orientations.

For users prioritizing memory capacity, memory bandwidth, FP16 throughput, and overall compute density, the H200 NVL is the stronger choice according to the recorded data. For users prioritizing lower power draw, a single-slot footprint, higher boost clocks, RT core support, and graphics API compatibility, the RTX PRO 4500 Blackwell Server is the appropriate selection. The database does not yet contain benchmark scores for the RTX PRO 4500, so its performance relative to the H200 NVL cannot be quantified. The H200 NVL's nearest rival comparisons show it delivering scores 13.2% above the L40S and 5.3% above the MI300X, while trailing the B200 and B300 SXM6 AC by 3.1% and 9.4%, respectively. These figures establish the H200 NVL as a mid-to-high tier server accelerator, while the RTX PRO 4500 remains an unmeasured entry in the database.
