NVIDIA H20 vs NVIDIA RTX PRO 6000 Blackwell Max-Q Comparison

Head-to-Head Benchmarks

The benchmark database contains no direct head-to-head test results between the NVIDIA H20 and the NVIDIA RTX PRO 6000 Blackwell Max-Q. The winsA and winsB fields are both zero, indicating that neither product has recorded a comparative victory over the other in any shared test. This absence of direct comparison data means any evaluation must rely on the individual specifications and the single recorded benchmark for the RTX PRO 6000 Blackwell Max-Q.

The only benchmark score available in the database comes from the RTX PRO 6000 Blackwell Max-Q, which achieved 11,088 points in 3DMark Steel Nomad DX12. This places the card at the 50th percentile among all GPUs tracked in the database. Its nearest rivals are tightly clustered: the NVIDIA RTX PRO 6000D Blackwell Max-Q scores identically at 11,088 points with a 0% delta, the AMD Radeon RX 550 scores 11,075 points (0.1% behind), and the NVIDIA GeForce GTX 1650 SUPER scores 11,047 points (0.4% behind). The AMD FirePro W4300 leads this group slightly with 11,225 points, putting the RTX PRO 6000 Blackwell Max-Q 1.2% behind that card.

The H20 has no benchmark entries and no nearest rivals listed. Its percentile vs all GPUs is also 50, matching the RTX PRO 6000 Blackwell Max-Q, but this percentile is computed from an average benchmark score of zero, meaning the H20 has no recorded performance data to analyze. The database treats both cards as being in the middle of the performance distribution, yet only one of them has actual measured results.

This asymmetry is notable. The H20's position at the 50th percentile with a zero average score suggests the database has not yet collected benchmark runs for this accelerator. The RTX PRO 6000 Blackwell Max-Q, by contrast, has a concrete data point that places it in a narrow performance band where a 0.4% difference separates it from the GTX 1650 SUPER and a 1.2% gap separates it from the FirePro W4300. These deltas are small enough that run-to-run variance could reorder the rankings, yet the database records them as distinct scores.

Architecture Differences

The two NVIDIA products come from different architectural generations. The H20 uses the GH100 chip based on the Hopper architecture, belonging to the Server Hopper (Hxx) generation. The RTX PRO 6000 Blackwell Max-Q uses the GB202 chip based on Blackwell 2.0, belonging to the Blackwell PRO W (x000) generation. Both chips are fabricated by TSMC on a 5 nm process node, but the transistor counts differ substantially. The H20's GH100 packs 80,000 million transistors on a 814 mm² die, yielding a transistor density of 98.3M per mm². The RTX PRO 6000's GB202 contains 92,200 million transistors on a smaller 750 mm² die, achieving a higher density of 122.9M per mm².

Clock behavior diverges sharply between the two. The H20 runs at a base clock of 1830 MHz and boosts to 1980 MHz. The RTX PRO 6000 Blackwell Max-Q starts at a much lower 1035 MHz base but boosts to 2280 MHz. This 300 MHz boost advantage for the Blackwell part comes with a dramatically different power envelope: the H20 draws 500 W TDP while the RTX PRO 6000 Blackwell Max-Q consumes only 300 W TDP. The H20 is an SXM module, while the RTX PRO 6000 Blackwell Max-Q is a dual-slot card with a 1x 16-pin power connector. The suggested PSU ratings are 900 W for the H20 and 700 W for the RTX PRO 6000 Blackwell Max-Q.

Memory subsystems reveal a fundamental design split. The H20 uses 96 GB of HBM3 on a 6144-bit bus, delivering 4.03 TB/s of bandwidth. The RTX PRO 6000 Blackwell Max-Q also has 96 GB, but uses GDDR7 on a 512-bit bus, achieving 1.79 TB/s. The H20's memory bandwidth is more than double that of the RTX PRO 6000 Blackwell Max-Q, a consequence of HBM3's wide bus versus GDDR7's narrower interface. Memory clocks reflect this: the H20 runs at 1313 MHz with 5.3 Gbps effective data rate, while the RTX PRO 6000 Blackwell Max-Q runs at 1750 MHz with 28 Gbps effective.

Compute resources are heavily skewed toward the RTX PRO 6000 Blackwell Max-Q. It has 24,064 shading units, 752 TMUs, 192 ROPs, 188 RT cores, and 752 tensor cores. The H20 has 9,984 shading units, 312 TMUs, 24 ROPs, no listed RT cores, and 312 tensor cores. Pixel rate tells the story: the RTX PRO 6000 Blackwell Max-Q reaches 437.8 GPixel/s versus 47.52 GPixel/s for the H20. Texture rate is 1,714.6 GTexel/s versus 617.8 GTexel/s. FP32 throughput is 109.7 TFLOPS versus 39.54 TFLOPS. FP16 differs in ratio style: the H20 delivers 79.07 TFLOPS at 2:1 ratio, while the RTX PRO 6000 Blackwell Max-Q delivers 109.7 TFLOPS at 1:1 ratio.

The API support also separates the two. The H20 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its server accelerator role. The RTX PRO 6000 Blackwell Max-Q supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs follow the same pattern: the H20 has no outputs, while the RTX PRO 6000 Blackwell Max-Q includes 4x DisplayPort 2.1b. Physical dimensions are recorded only for the RTX PRO 6000 Blackwell Max-Q: 267 mm length, 111 mm height, 40 mm width.

Where Each One Wins

Based on the recorded data, the RTX PRO 6000 Blackwell Max-Q wins in raw compute throughput. Its FP32 performance of 109.7 TFLOPS is roughly 2.8 times the H20's 39.54 TFLOPS. Texture rate favors the Blackwell card by a factor of about 2.8 as well (1,714.6 GTexel/s versus 617.8 GTexel/s). Pixel rate shows an even larger gap, with the RTX PRO 6000 Blackwell Max-Q delivering 437.8 GPixel/s versus 47.52 GPixel/s, a 9.2 times advantage. Shading units, TMUs, and ROPs are all substantially higher on the Blackwell card, indicating its design targets graphics-heavy workloads with high resolution and high geometric complexity.

The H20 wins in memory bandwidth. Its 4.03 TB/s exceeds the RTX PRO 6000 Blackwell Max-Q's 1.79 TB/s by a factor of 2.25. This bandwidth advantage, combined with HBM3 memory and a 6144-bit bus, positions the H20 for data-intensive workloads where memory throughput becomes the bottleneck rather than compute. The H20 also has a higher base clock (1830 MHz versus 1035 MHz), though its boost clock is lower (1980 MHz versus 2280 MHz). The H20's 500 W TDP versus 300 W TDP suggests it can sustain high memory bandwidth operations, but the database does not provide efficiency metrics.

The RTX PRO 6000 Blackwell Max-Q has RT cores (188 of them), while the H20 lists none. This makes ray tracing acceleration available only on the Blackwell card. The RTX PRO 6000 Blackwell Max-Q also has display outputs and a full graphics API stack, enabling workstation visualization tasks that the H20 cannot perform. The H20's lack of display outputs and API support confines it to compute-only server deployments.

The release dates differ by roughly 14 months. The H20 launched on January 31, 2024, while the RTX PRO 6000 Blackwell Max-Q launched on March 17, 2025. Both are marked as Active in production status. The H20's predecessor is Server Ada and its successor is Server Blackwell, while the RTX PRO 6000 Blackwell Max-Q's predecessor is Workstation Ada and it has no listed successor.

The Verdict

The recorded data supports a clear split in use cases. The RTX PRO 6000 Blackwell Max-Q is the choice for graphics-intensive workloads that require high FP32 throughput, texture processing, pixel fill rates, and ray tracing. Its 109.7 TFLOPS FP32 performance, 752 TMUs, 192 ROPs, and 188 RT cores provide the compute infrastructure for 3D rendering, CAD visualization, and real-time graphics work. The 4x DisplayPort 2.1b outputs and DirectX 12 Ultimate support confirm this orientation. Its single recorded benchmark score of 11,088 in 3DMark Steel Nomad DX12 places it in a cluster with other mid-range GPUs, though the small deltas (0.1% to 1.2%) suggest the test does not heavily differentiate among these cards.

The H20 is the choice for memory-bandwidth-bound server workloads. Its 4.03 TB/s bandwidth, 96 GB HBM3 capacity, and 6144-bit bus exceed the RTX PRO 6000 Blackwell Max-Q in every memory metric. The H20's 500 W TDP and SXM form factor indicate a data-center-oriented design optimized for large-scale data movement rather than graphics output. Its lack of display outputs and graphics API support reinforces that it is not intended for workstation visualization.

For users who need both compute and graphics, the RTX PRO 6000 Blackwell Max-Q is the only option with display outputs and a graphics API stack. For users who need maximum memory bandwidth for server-side inference, training, or scientific computing, the H20's 4.03 TB/s bandwidth is the defining advantage. The 300 W TDP of the RTX PRO 6000 Blackwell Max-Q versus 500 W for the H20 also affects deployment density, though the database does not provide efficiency benchmarks to quantify this.

The H20's zero average benchmark score limits direct performance conclusions. Its 50th percentile ranking is identical to the RTX PRO 6000 Blackwell Max-Q, but this is computed from no actual measurements. The database has not yet recorded any H20 benchmark runs. This absence means any comparison between the two in compute throughput relies entirely on specification analysis rather than measured results.
