NVIDIA GeForce RTX 5070 vs NVIDIA H20 Comparison

The Verdict

The database contains two very different NVIDIA accelerators. The GeForce RTX 5070 is a client graphics card with a complete set of benchmark results, while the NVIDIA H20 is a server accelerator with no recorded benchmark scores in the database. The RTX 5070 has an average benchmark score of 40377 across its tested workloads, placing it at the 82nd percentile of all GPUs. The H20 has an average benchmark score of zero, with no benchmark entries, placing it at the 50th percentile by default. Based strictly on the recorded data, the RTX 5070 is the only one of the two with measurable graphics performance. The H20 cannot be evaluated for client rendering tasks because its API support is listed as N/A for DirectX, OpenGL, and Vulkan, and it has no display outputs.

For users seeking a graphics card for standard rendering workloads, the RTX 5070 is the choice, as it is the only option with data. The H20, by contrast, is a compute-oriented server module with no display outputs and no graphics API support, so the recorded data does not support any client-side use case for it. The H20 does offer substantially more memory and a wider memory bus, but without benchmark scores, its relative performance cannot be quantified. The verdict from the data is straightforward: pick the RTX 5070 for any measured graphics workload, and recognize the H20 as a server accelerator whose performance is unmeasured in this database.

Where Each One Wins

The RTX 5070 wins on every benchmark category where data exists, because the H20 has no benchmark entries. The RTX 5070 posts a 3DMark Steel Nomad DX12 score of 5077, a Geekbench OpenCL score of 172660, and a Geekbench Vulkan score of 178923. In Passmark tests, it records 29137 in G3D, 15787 in GPU Compute, 1305 in G2D, 320 in DirectX 9, 277 in DirectX 11, 180 in DirectX 10, and 108 in DirectX 12. These are the only recorded performance figures between the two products.

The H20 does not win any benchmark category because no scores are recorded for it. Its strengths lie in its specifications, not its measured results. The H20 has 96 GB of HBM3 memory, a 6144-bit memory bus, and 4.03 TB/s of memory bandwidth. The RTX 5070 has 12 GB of GDDR7 memory, a 192-bit bus, and 672.0 GB/s of bandwidth. In memory capacity and bandwidth, the H20 is the clear specification leader, but the database does not contain a single benchmark score to confirm how that translates into performance.

The use-case split is therefore defined by architecture and intended role. The RTX 5070 is a dual-slot client card with 245 mm length, display outputs including 1x HDMI 2.1b and 3x DisplayPort 2.1b, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The H20 is an SXM Module with no display outputs and no graphics API support. The RTX 5070 is built for rendering and graphics workloads, while the H20 is built for server compute, but the latter has no measured data to support a performance claim.

Architecture Differences

The two GPUs come from different NVIDIA architectures and process nodes. The RTX 5070 uses the GB205 chip, built on the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It contains 31,100 million transistors on a 263 mm² die, yielding a transistor density of 118.3 million per mm². The H20 uses the GH100 chip, built on the Hopper architecture, also on a 5 nm process at TSMC. The H20 has 80,000 million transistors on an 814 mm² die, for a density of 98.3 million per mm². The H20 has more than double the transistor count and more than triple the die area.

The clock speeds differ. The RTX 5070 has a base clock of 2325 MHz and a boost clock of 2512 MHz. The H20 runs at a base of 1830 MHz and a boost of 1980 MHz. The RTX 5070 has higher clocks, but the H20 has more execution resources. The RTX 5070 has 6144 shading units, 192 texture mapping units, 80 render output units, 48 ray tracing cores, and 192 tensor cores. The H20 has 9984 shading units, 312 TMUs, 24 ROPs, no recorded ray tracing cores, and 312 tensor cores.

The memory subsystems are fundamentally different. The RTX 5070 uses 12 GB of GDDR7 memory on a 192-bit bus, with a memory clock of 1750 MHz (28 Gbps effective) and 672.0 GB/s of bandwidth. The H20 uses 96 GB of HBM3 on a 6144-bit bus, with a memory clock of 1313 MHz (5.3 Gbps effective) and 4.03 TB/s of bandwidth. The H20 has eight times the capacity and roughly six times the bandwidth. The pixel rate is 201.0 GPixel/s for the RTX 5070 versus 47.52 GPixel/s for the H20, while texture rate is 482.3 GTexel/s for the RTX 5070 versus 617.8 GTexel/s for the H20.

The compute ratings show a specific split. The RTX 5070 delivers 30.87 TFLOPS of FP32 and 30.87 TFLOPS of FP16 with a 1:1 ratio. The H20 delivers 39.54 TFLOPS of FP32 and 79.07 TFLOPS of FP16 with a 2:1 ratio. The H20 has higher FP32 and much higher FP16 throughput. The power envelopes differ as well, with the RTX 5070 at 250 W TDP and a suggested PSU of 600 W, while the H20 is rated at 500 W TDP with a suggested PSU of 900 W. The RTX 5070 uses a 1x 16-pin power connector, while the H20 has no recorded power connectors due to its SXM Module form factor. The RTX 5070 is a dual-slot card with dimensions of 245 mm length, 115 mm height, and 40 mm width. The H20 has no recorded dimensions. The RTX 5070 uses PCIe 5.0 x16, as does the H20. The release dates differ, with the RTX 5070 launching on March 3, 2025, and the H20 launching on January 31, 2024. The RTX 5070 has a launch MSRP of 549 USD.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for these two products. The RTX 5070 has a full set of results, while the H20 has none. The comparison therefore relies on the RTX 5070's absolute scores and its position relative to other GPUs.

The RTX 5070 scores 5077 in 3DMark Steel Nomad DX12. In Geekbench, it records 172660 in OpenCL and 178923 in Vulkan, with the Vulkan score being 3.6% higher than the OpenCL score. Passmark results show a G3D score of 29137, a GPU Compute score of 15787, and a G2D score of 1305. Among the DirectX legacy tests, DirectX 9 scores highest at 320, followed by DirectX 11 at 277, DirectX 10 at 180, and DirectX 12 at 108. The G3D score is 84.6% higher than the GPU Compute score. The average benchmark score across all entries is 40377, and the GPU sits at the 82nd percentile of all GPUs in the database.

Relative to its nearest rivals, the RTX 5070's average score of 40377 is nearly identical to the AMD Radeon Pro 580's 40318, a delta of just 0.1%. It is 0.8% above the AMD Radeon Pro WX 7100's 40063 and 2% above the NVIDIA RTX A500 Mobile's 39568. The only rival ahead is the AMD Radeon Pro 5300 at 40870, which leads by 1.2%. These deltas are all within a narrow band, meaning the RTX 5070's measured performance is closely clustered with these professional and mobile GPUs.

The H20's absence from benchmark results means no direct wins can be credited to it. Its specification sheet suggests a different role: 96 GB of HBM3, a 6144-bit bus, 4.03 TB/s bandwidth, 9984 shading units, 312 tensor cores, and 79.07 TFLOPS of FP16 compute. The RTX 5070 counters with higher clocks (2512 MHz boost versus 1980 MHz), a higher pixel rate (201.0 GPixel/s versus 47.52 GPixel/s), and full graphics API support. The recorded data shows the RTX 5070 as the only one of the two with measurable benchmark performance, and the H20 as a server accelerator with no client-facing graphics capability.
