NVIDIA H20 vs NVIDIA RTX PRO 5000 Blackwell Comparison

The Verdict

The NVIDIA H20 and NVIDIA RTX PRO 5000 Blackwell serve fundamentally different roles, and the recorded data draws a clear line between them. The H20 is a server-oriented Hopper part with a massive 96 GB HBM3 pool, a 6144-bit bus, and 4.03 TB/s of memory bandwidth. The RTX PRO 5000 Blackwell is a workstation card built on the Blackwell 2.0 architecture, with a smaller 48 GB GDDR7 frame buffer, a 384-bit bus, and 1.34 TB/s of bandwidth.

The RTX PRO 5000 Blackwell holds the only benchmark scores in the database. It posts a 3DMark Steel Nomad DX12 score of 9579.5, a Geekbench OpenCL score of 254116, and a Geekbench Vulkan score of 282631. Its average benchmark score sits at 182109, placing it in the 98th percentile of all GPUs. The nearest rival, the NVIDIA A100 SXM4 80 GB, averages 183725, a delta of -0.9%, meaning the RTX PRO 5000 trails by less than one percent. The RTX 5000 Ada Generation averages 184664, a -1.4% delta. The GeForce RTX 4090 D trails at 178050, a 2.3% delta in favor of the RTX PRO 5000. The A100 SXM4 40 GB averages 187147, a -2.7% delta.

The H20 has no recorded benchmarks, no average score, and a 50th percentile ranking. Its wins column is zero. For any workload where measured performance is required, the RTX PRO 5000 Blackwell is the only part with data. The H20 is a compute-focused server module with no display outputs, while the RTX PRO 5000 offers four DisplayPort 2.1b outputs and a full API stack including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The verdict from the data is straightforward: the RTX PRO 5000 Blackwell is the choice for workstation graphics and general compute with quantified results. The H20 targets memory-capacity-heavy server roles, but no benchmark evidence exists to quantify its performance in this database.

Architecture Differences

The two GPUs come from different architectural generations. The H20 uses the GH100 chip on the Hopper architecture, produced on a 5 nm process at TSMC. The RTX PRO 5000 Blackwell uses the GB202 chip on the Blackwell 2.0 architecture, also on a 5 nm process at TSMC. The transistor counts differ significantly: the H20 packs 80,000 million transistors across an 814 mm² die, yielding a density of 98.3 million transistors per square millimeter. The RTX PRO 5000 has 92,200 million transistors on a 750 mm² die, with a higher density of 122.9 million per square millimeter. Despite the smaller die, the Blackwell part crams more transistors in, a 24.9 million per mm² density advantage.

Clock behavior also diverges. The H20 has a base clock of 1830 MHz and a boost clock of 1980 MHz. The RTX PRO 5000 has a lower base of 1740 MHz but a much higher boost of 2377 MHz. The H20's memory runs at 1313 MHz with 5.3 Gbps effective, while the RTX PRO 5000's GDDR7 memory runs at 1750 MHz with 28 Gbps effective.

The memory subsystems are built for different purposes. The H20 uses HBM3 with 96 GB capacity, a 6144-bit bus, and 4.03 TB/s bandwidth. The RTX PRO 5000 uses GDDR7 with 48 GB capacity, a 384-bit bus, and 1.34 TB/s bandwidth. The H20 has three times the capacity and three times the bandwidth, but the RTX PRO 5000 has a much faster effective memory clock.

Compute resources differ sharply. The H20 has 9984 shading units, 312 texture mapping units, and only 24 ROPs. The RTX PRO 5000 has 14080 shading units, 440 TMUs, and 160 ROPs. The RTX PRO 5000 also includes 110 RT cores, while the H20 lists none. Tensor cores are present on both: 312 on the H20 versus 440 on the RTX PRO 5000.

Pixel and texture rates follow the ROP and TMU counts. The H20 delivers 47.52 GPixel/s and 617.8 GTexel/s. The RTX PRO 5000 delivers 380.3 GPixel/s and 1,045.9 GTexel/s. The RTX PRO 5000's pixel rate is eight times higher, reflecting its 160 ROPs versus 24.

FP32 throughput heavily favors the RTX PRO 5000. It delivers 66.94 TFLOPS, versus the H20's 39.54 TFLOPS. FP16 is a different story: the H20 hits 79.07 TFLOPS with a 2:1 ratio, while the RTX PRO 5000 delivers 66.94 TFLOPS at a 1:1 ratio. The H20's FP16 advantage suggests a design tilted toward mixed-precision server workloads.

Power and physical design separate the two as well. The H20 is a 500 W SXM module with no display outputs, no power connector specified, and a suggested PSU of 900 W. The RTX PRO 5000 is a dual-slot card at 300 W, uses a single 16-pin connector, suggests a 700 W PSU, and measures 267 mm by 111 mm by 40 mm. The H20 has no API support listed for DirectX, OpenGL, or Vulkan, while the RTX PRO 5000 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The H20 wins on memory capacity and bandwidth. With 96 GB of HBM3 and 4.03 TB/s, it holds a 48 GB and 2.69 TB/s advantage over the RTX PRO 5000. For workloads that need to hold very large datasets on the GPU, the H20's frame buffer is the clear winner. The H20 also leads in FP16 compute, delivering 79.07 TFLOPS versus 66.94 TFLOPS from the RTX PRO 5000, a 12.13 TFLOPS gap.

The RTX PRO 5000 wins on every measured benchmark and most raw compute metrics. Its 66.94 TFLOPS FP32 output is 27.4 TFLOPS ahead of the H20. Its 1,045.9 GTexel/s texture rate and 380.3 GPixel/s pixel rate dwarf the H20's 617.8 GTexel/s and 47.52 GPixel/s. It has more shading units, more TMUs, more ROPs, more tensor cores, and it includes RT cores where the H20 has none.

The RTX PRO 5000 also wins on efficiency per watt. It produces 66.94 TFLOPS FP32 at 300 W, while the H20 produces 39.54 TFLOPS at 500 W. That translates to 0.223 TFLOPS per watt for the RTX PRO 5000 versus 0.079 TFLOPS per watt for the H20. The RTX PRO 5000 is nearly three times more efficient in FP32 per watt.

For workstation use, the RTX PRO 5000 is the only option with display outputs, offering four DisplayPort 2.1b connections. The H20 has no outputs, making it unsuitable for any interactive graphics role. The RTX PRO 5000's API support, including DirectX 12 Ultimate and Vulkan 1.4, confirms its graphics-oriented design.

The H20's 50th percentile ranking versus the RTX PRO 5000's 98th percentile shows a massive gap in overall standing within the database. Even without benchmarks, the percentile alone indicates the H20 sits at the median of all GPUs, while the RTX PRO 5000 sits near the top.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the H20 and RTX PRO 5000. The H20 has an empty benchmark array and an average score of zero. The RTX PRO 5000, by contrast, has three recorded scores. The 3DMark Steel Nomad DX12 result of 9579.5 represents a modern DirectX 12 workload. The Geekbench OpenCL score of 254116 measures general compute throughput. The Geekbench Vulkan score of 282631 measures graphics and compute under the Vulkan API. These are the only quantified performance data points available, and all belong to the RTX PRO 5000.

The nearest rival comparisons reinforce the RTX PRO 5000's position. Against the A100 SXM4 80 GB, the RTX PRO 5000 trails by 0.9%. Against the RTX 5000 Ada Generation, it trails by 1.4%. Against the GeForce RTX 4090 D, it leads by 2.3%. Against the A100 SXM4 40 GB, it trails by 2.7%. These deltas show the RTX PRO 5000 sits within a tight performance band around the A100 and RTX 5000 Ada, while staying ahead of the RTX 4090 D.

The H20's lack of data means no wins can be recorded for it. Its 50th percentile ranking positions it at the median of all GPUs in the database, far below the RTX PRO 5000's 98th percentile. The raw specification comparison tells a similar story in most categories. The RTX PRO 5000 leads in shading units (14080 versus 9984), TMUs (440 versus 312), ROPs (160 versus 24), tensor cores (440 versus 312), boost clock (2377 MHz versus 1980 MHz), FP32 (66.94 versus 39.54 TFLOPS), pixel rate (380.3 versus 47.52 GPixel/s), and texture rate (1,045.9 versus 617.8 GTexel/s).

The H20 leads in memory size (96 GB versus 48 GB), memory bandwidth (4.03 versus 1.34 TB/s), memory bus width (6144 versus 384 bit), FP16 compute (79.07 versus 66.94 TFLOPS), and transistor count (80,000 versus 92,200 million is actually a loss, but the H20 has a larger die at 814 mm² versus 750 mm²). The H20's FP16 advantage of 12.13 TFLOPS is notable but comes at a 200 W power cost.

In FP32 per watt, the RTX PRO 5000 is dramatically more efficient. At 66.94 TFLOPS and 300 W, it achieves 0.223 TFLOPS per watt. The H20, at 39.54 TFLOPS and 500 W, achieves 0.079 TFLOPS per watt. The RTX PRO 5000 is roughly 2.8 times more efficient by this metric.

Specification Differences

The two parts diverge across nearly every specification field. The H20 uses the GH100 chip with 80,000 million transistors on an 814 mm² die. The RTX PRO 5000 uses the GB202 chip with 92,200 million transistors on a 750 mm² die.
