NVIDIA GeForce RTX 4070 vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between the NVIDIA GeForce RTX 4070 and the NVIDIA H20. The RTX 4070 has a complete set of ten benchmark scores across DirectX 9 through DirectX 12, OpenCL, Vulkan, and compute workloads. The H20 has no recorded benchmark scores in the database, leaving its average benchmark score at zero. The RTX 4070 holds an 81st percentile ranking among all GPUs, while the H20 sits at the 50th percentile. This percentile difference reflects the fact that the RTX 4070 has measurable performance data while the H20 has none recorded.

The RTX 4070's strongest recorded result is its Geekbench Vulkan score of 174,152, followed by its Geekbench OpenCL score of 154,858. Its 3DMark Steel Nomad DX12 score is 3,854. In Passmark tests, the DirectX 11 score of 244 leads its DirectX 10 score of 139 and DirectX 12 score of 103. The DirectX 9 score is 320, which is the highest among the Passmark DirectX tests. The GPU compute score is 14,720, and the G3D score is 26,927. The G2D score is 1,164. The average benchmark score across all ten tests is 37,648.

Nearest rivals for the RTX 4070 in the database include the NVIDIA Tesla P4 with an average score of 37,628, a 0.1 percent difference. The AMD Radeon RX Vega 56 averages 37,507, a 0.4 percent gap. The NVIDIA GeForce RTX 4080 Mobile averages 38,135, putting it 1.3 percent ahead of the RTX 4070. The AMD Radeon PRO W6400 averages 37,157, which is 1.3 percent behind. These tight margins place the RTX 4070 in a cluster of similarly performing products, with no single rival more than 1.3 percent away in either direction.

Because the H20 has no benchmark entries and no nearest rivals listed, the head-to-head comparison is limited to architectural and specification differences. The data cannot support any direct performance claim between these two cards beyond what the RTX 4070's own scores demonstrate.

The Verdict

The recorded data shows two products with fundamentally different purposes. The RTX 4070 is a consumer graphics card with a complete benchmark profile, a launch MSRP of 599 USD, and an end-of-life production status. It targets DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 APIs, and it includes display outputs. The H20 is an active server accelerator with no display outputs, no consumer API support, and no recorded benchmarks. Its launch MSRP is absent from the database.

For anyone selecting based on measured performance, the RTX 4070 is the only option with data. Its 81st percentile ranking and average score of 37,648 provide a concrete reference point. The H20's 50th percentile ranking with zero average score indicates that no comparable measurements exist in the database. The H20's specifications, however, show a much larger memory capacity of 96 GB of HBM3 compared to the RTX 4070's 12 GB of GDDR6X. The H20 also has a wider 6144-bit memory bus and 4.03 TB/s of bandwidth, versus the RTX 4070's 192-bit bus and 504.2 GB/s.

The verdict from the data is clear: the RTX 4070 suits client-side rendering and consumer workloads where DirectX and Vulkan support matter. The H20 suits server-side compute where memory capacity and bandwidth dominate, despite having no benchmark scores to validate that role. The choice depends on whether the workload requires graphics APIs and display output or massive memory throughput.

Where Each One Wins

The RTX 4070 wins in every measured category because it has all ten benchmark scores. Its 3DMark Steel Nomad DX12 score of 3,854 and Passmark G3D score of 26,927 indicate strong graphics rendering capability. Its Geekbench Vulkan score of 174,152 and OpenCL score of 154,858 show solid compute throughput for a consumer card. The Passmark GPU compute score of 14,720 adds further evidence of general-purpose processing ability. The RTX 4070 also wins on API compatibility, supporting DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, which the H20 lacks entirely.

The H20 wins on raw memory resources. Its 96 GB of HBM3 memory is eight times the RTX 4070's 12 GB. Its 4.03 TB/s bandwidth is roughly eight times the RTX 4070's 504.2 GB/s. The H20 has 9,984 shading units versus 5,888, and 312 tensor cores versus 184. Its FP32 throughput of 39.54 TFLOPS exceeds the RTX 4070's 29.15 TFLOPS. Its FP16 throughput of 79.07 TFLOPS with a 2:1 ratio doubles the RTX 4070's 29.15 TFLOPS with a 1:1 ratio. The H20 also has 312 texture mapping units versus 184, and a higher texture rate of 617.8 GTexel/s versus 455.4 GTexel/s.

The RTX 4070 wins on pixel rate with 158.4 GPixel/s versus the H20's 47.52 GPixel/s, a consequence of the H20 having only 24 ROPs compared to 64. The RTX 4070 also has higher clock speeds, with a boost of 2475 MHz versus 1980 MHz. The H20 uses a PCIe 5.0 x16 interface, while the RTX 4070 uses PCIe 4.0 x16, giving the H20 a newer bus standard.
