NVIDIA GeForce RTX 5070 SUPER vs NVIDIA H20 Comparison

Where Each One Wins

The recorded data presents an unusual comparison: the GeForce RTX 5070 SUPER has a single measured benchmark score, while the H20 has no benchmark entries at all. This means the direct head-to-head comparison is effectively one-sided in terms of available measurements. The RTX 5070 SUPER scores 2690 in 3DMark Steel Nomad DX12, placing it at the 18th percentile among all GPUs in the database. Its nearest rivals in that test are the Quadro K1100M (2664, 1% slower), the GeForce GT 1030 (2662, 1.1% slower), and the Intel Arc Pro B50 (2660, 1.1% slower). The H20, by contrast, has zero recorded benchmark scores and an average benchmark score of zero, though it sits at the 50th percentile overall due to its specifications.

The RTX 5070 SUPER is the clear winner in any scenario involving DirectX 12 gaming workloads, as it is the only one of the two with a measurable 3DMark result. It delivers a functional score where the H20 delivers nothing in the recorded data. The H20, however, wins on paper in raw compute resources: it has 9984 shading units versus 6400, 312 tensor cores versus 200, and 312 TMUs versus 200. Its FP32 throughput is 39.54 TFLOPS versus 32.15 TFLOPS, and its FP16 throughput is 79.07 TFLOPS versus 32.15 TFLOPS. These are advantages that matter for server-side parallel workloads, but without benchmark scores to confirm real-world performance, they remain theoretical strengths.

For a gamer or workstation user running DirectX 12 applications, the RTX 5070 SUPER is the only viable option in this pair. For a data-center operator focused on massive memory capacity and tensor throughput, the H20 presents the more compelling specification sheet. The H20 also offers 96 GB of HBM3 memory with 4.03 TB/s of bandwidth, figures that dwarf the RTX 5070 SUPER's 18 GB GDDR7 and 672.0 GB/s. The RTX 5070 SUPER wins on pixel throughput (201.0 GPixel/s versus 47.52 GPixel/s) and on having any display outputs at all, while the H20 wins on texture rate (617.8 GTexel/s versus 502.4 GTexel/s), memory capacity, and memory bandwidth.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs. The only recorded score belongs to the RTX 5070 SUPER: 2690 in 3DMark Steel Nomad DX12. This score places it at the 18th percentile among all GPUs. Its nearest competitor in that test is the Quadro K1100M with 2664, a 1% difference. The GeForce GT 1030 scores 2662, 1.1% lower. The Intel Arc Pro B50 scores 2660, 1.1% lower. The GeForce GT 440 scores 2645, 1.7% lower. These deltas are small, indicating the RTX 5070 SUPER's measured performance is narrowly ahead of a set of much older or lower-tier GPUs.

The H20 has no benchmark scores in the database. Its average benchmark score is zero, and it has no nearest rivals listed. This absence means any performance comparison must rely on specification analysis rather than measured results. The H20's 50th percentile ranking is derived from its specification profile, not from any executed test. The RTX 5070 SUPER's 18th percentile, conversely, reflects its actual Steel Nomad result.

For FP32 compute, the H20's 39.54 TFLOPS exceeds the RTX 5070 SUPER's 32.15 TFLOPS by 7.39 TFLOPS, a 23% margin. For FP16, the gap widens: the H20's 79.07 TFLOPS is more than double the RTX 5070 SUPER's 32.15 TFLOPS. The H20 achieves this via a 2:1 FP16 ratio, while the RTX 5070 SUPER runs FP16 at 1:1. The H20 also has 312 tensor cores versus 200, which supports its server-oriented design.

The RTX 5070 SUPER counters with a substantially higher pixel rate. At 201.0 GPixel/s, it outperforms the H20's 47.52 GPixel/s by a factor of 4.2. The RTX 5070 SUPER also has a higher base clock (2325 MHz versus 1830 MHz) and boost clock (2512 MHz versus 1980 MHz). Its memory clock of 1750 MHz (28 Gbps effective) is higher than the H20's 1313 MHz (5.3 Gbps effective), though the H20's wider bus and HBM3 technology deliver far more total bandwidth.

Specification Differences

The most glaring difference is memory. The H20 uses 96 GB of HBM3 on a 6144-bit bus, yielding 4.03 TB/s bandwidth. The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus, yielding 672.0 GB/s. The H20's bandwidth is exactly 6 times higher. The H20's memory clock is lower at 1313 MHz versus 1750 MHz, but the 32 times wider bus compensates massively.

Shading units differ: 9984 on the H20 versus 6400 on the RTX 5070 SUPER. TMUs differ: 312 versus 200. ROPs differ in the opposite direction: 24 on the H20 versus 80 on the RTX 5070 SUPER. Tensor cores differ: 312 versus 200. The RTX 5070 SUPER has 50 RT cores; the H20 has none listed.

Power and cooling differ substantially. The RTX 5070 SUPER is a dual-slot card with a 1x 16-pin connector and 275 W TDP. The H20 is an SXM Module with no power connector listed, a 500 W TDP, and a suggested PSU of 900 W. The RTX 5070 SUPER has dimensions of 245 mm length, 115 mm height, and 40 mm width. The H20 has no listed dimensions. The RTX 5070 SUPER has display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b); the H20 has none.

The die sizes differ: the RTX 5070 SUPER uses a 263 mm² die with 31,100 million transistors, while the H20 uses an 814 mm² die with 80,000 million transistors. Transistor density is 118.3M per mm² for the RTX 5070 SUPER versus 98.3M per mm² for the H20. Both use a 5 nm process at TSMC.

Architecture Differences

The RTX 5070 SUPER is built on Blackwell 2.0 architecture, using the GB205 chip. The H20 uses Hopper architecture with the GH100 chip. Blackwell 2.0 is the GeForce 50-series generation, while Hopper is the Server Hopper (Hxx) generation. The RTX 5070 SUPER's predecessor and successor are both null in the database. The H20's predecessor is Server Ada, and its successor is Server Blackwell.

The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H20 lists all three APIs as N/A, indicating it is not designed for graphics rendering. The RTX 5070 SUPER has RT cores for ray tracing; the H20 has no RT core count listed. The H20 instead emphasizes tensor cores, with 312 units, and a 2:1 FP16 ratio that doubles its tensor math throughput.

The H20's memory subsystem is architecturally different: HBM3 stacked memory on a 6144-bit interface versus GDDR7 on a 192-bit interface. This reflects the H20's server compute focus, where memory bandwidth and capacity are critical for large model workloads. The RTX 5070 SUPER's GDDR7 and 80 ROPs reflect a rasterization-oriented design, prioritizing pixel output and gaming performance.

Both use PCIe 5.0 x16 as their bus interface. Both are fabricated on a 5 nm process at TSMC. The H20 is an SXM Module, meaning it mounts into a server chassis rather than a typical desktop slot. The RTX 5070 SUPER is a dual-slot card with standard display outputs, indicating desktop consumer use. The H20 has no display outputs at all, confirming its headless server role.

The Verdict

The data supports a clear split by use case. The GeForce RTX 5070 SUPER is the only GPU here with a measured benchmark score. Its 2690 in 3DMark Steel Nomad DX12 gives it a concrete performance data point, even if that point sits at the 18th percentile. It has 80 ROPs, 201.0 GPixel/s pixel rate, display outputs, and full graphics API support. For any DirectX 12 workload, a game, a 3D renderer, or a workstation application, the RTX 5070 SUPER is the functional choice based on the recorded data.

The H20 offers no benchmark scores, no graphics APIs, and no display outputs. Its advantages are purely specification-based: 9984 shading units, 312 tensor cores, 39.54 TFLOPS FP32, 79.07 TFLOPS FP16, 96 GB HBM3, and 4.03 TB/s bandwidth. These are server-class compute resources. The 50th percentile ranking suggests the database considers its specifications mid-pack among all GPUs, but there is no measured result to validate any workload performance.

A builder assembling a gaming PC or a workstation with monitor output should choose the RTX 5070 SUPER. Its 18 GB GDDR7 memory, 672.0 GB/s bandwidth, and 2512 MHz boost clock are tuned for interactive graphics. A data-center operator needing large memory capacity and tensor throughput for compute tasks should look at the H20, provided the software stack does not require DirectX or Vulkan. The H20's 500 W TDP and 900 W suggested PSU indicate a power-hungry server installation, while the RTX 5070 SUPER's 275 W TDP fits a standard desktop.

The RTX 5070 SUPER wins the only recorded benchmark by default. The H20 wins the specification comparison on compute throughput and memory capacity. Neither GPU is a substitute for the other; they target different segments. The data does not support a single overall winner, only a situational one.
