AMD Radeon RX 9070 vs NVIDIA H20 Comparison

Where Each One Wins

The recorded data draws a sharp divide between these two accelerators. The AMD Radeon RX 9070 is a client-focused graphics card with a full suite of DirectX, OpenGL, and Vulkan support, and it delivers measurable scores across ten benchmark tests. The NVIDIA H20, by contrast, is a server accelerator with no display outputs and no recorded benchmark entries in the database. Its average benchmark score is 0, and its percentile rank among all GPUs is 50, meaning it sits at the median of the database's tracked devices without any direct performance measurements.

For the RX 9070, the benchmark wins are concentrated in real-time graphics workloads. Its strongest result appears in PassMark G3D with a score of 25,381, which contributes heavily to its average benchmark score of 23,877. The card also posts a 3DMark Steel Nomad DX12 score of 6,290, a Geekbench OpenCL score of 131,539, and a Geekbench Vulkan score of 58,705. These numbers indicate that the RX 9070 is designed for interactive rendering, rasterization, and compute tasks that run through graphics APIs.

The H20 has no wins in any benchmark category because there are no recorded tests for it. The data shows its role is entirely different: it uses HBM3 memory, a 6144-bit bus, and 312 tensor cores, all of which point to server-side workloads such as large-scale matrix operations and AI inference. The absence of display outputs and graphics API support confirms it is not intended for desktop gaming or workstation visualization. In this comparison, every measurable victory belongs to the RX 9070, but that is a function of the database's test suite, which focuses on graphics-oriented benchmarks rather than the H20's specialized compute domain.

Architecture Differences

The two chips diverge at the fundamental level of process technology and die design. The RX 9070 uses the Navi 48 chip built on TSMC's 4 nm node, containing 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0 million transistors per square millimeter. The H20 uses the GH100 chip on TSMC's 5 nm node, with 80,000 million transistors spread across a much larger 814 mm² die, for a density of 98.3 million per square millimeter. The RX 9070 is denser per area, but the H20 packs roughly 48% more transistors overall.

Architecturally, the RX 9070 is based on RDNA 4.0 and belongs to the Navi IV (RX 9000) generation. It has 3,584 shading units, 224 texture mapping units, 128 ROPs, and 56 ray tracing cores. The H20 is based on the Hopper architecture from the Server Hopper (Hxx) generation. It has 9,984 shading units, 312 texture mapping units, 24 ROPs, and 312 tensor cores, but it has no listed ray tracing cores. The shading unit count is nearly three times higher on the H20, yet its ROP count is dramatically lower, reflecting a design optimized for compute throughput rather than pixel output.

Memory subsystems are equally divergent. The RX 9070 uses 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The H20 uses 96 GB of HBM3 on a 6144-bit bus, achieving 4.03 TB/s, which is over six times the bandwidth of the RX 9070. Clock speeds also differ: the RX 9070 has a base clock of 1330 MHz, a game clock of 2070 MHz, and a boost clock of 2520 MHz, while the H20 runs at 1830 MHz base and 1980 MHz boost with no game clock.

The power profiles reflect their intended environments. The RX 9070 has a TDP of 220 W, a dual-slot cooler, and two 8-pin power connectors, with a suggested PSU of 550 W. The H20 draws 500 W, uses an SXM module form factor, and requires a 900 W suggested PSU. The RX 9070 supports PCIe 5.0 x16 and offers 1x HDMI 2.1b plus 3x DisplayPort 2.1a outputs, while the H20 also uses PCIe 5.0 x16 but has no display outputs at all. The RX 9070 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4; the H20 lists N/A for all three graphics APIs.

Head-to-Head Benchmarks

Since the H20 has no recorded benchmark scores, the head-to-head comparison is one-sided. The RX 9070's average benchmark score of 23,877 stands against the H20's average of 0. The RX 9070 also achieves a 69th percentile rank across all GPUs in the database, while the H20 sits at the 50th percentile. These figures place the RX 9070 in the upper third of tracked graphics hardware, whereas the H20's percentile reflects its lack of measured graphics performance rather than any intrinsic capability.

Looking at the RX 9070's nearest rivals provides context for its standing. The database lists the NVIDIA GeForce GTX TITAN Z with an average score of 23,736, which is 0.6% lower than the RX 9070. The AMD Radeon RX 6800S scores 24,063, putting it 0.8% above the RX 9070. The NVIDIA GeForce RTX 3080 Mobile scores 23,628, which is 1.1% lower, and the NVIDIA GeForce RTX 2080 SUPER scores 24,170, which is 1.2% higher. These deltas are all within a narrow 2.3% band, indicating that the RX 9070 performs competitively with a group of previous-generation desktop and mobile cards.

The individual benchmark breakdown for the RX 9070 shows its strongest areas. PassMark G3D at 25,381 is the highest single score, followed by Geekbench OpenCL at 131,539 and Geekbench Vulkan at 58,705. The 3DMark Steel Nomad DX12 score of 6,290 is a modern DirectX 12 workload. Legacy DirectX tests show lower scores: PassMark DirectX 11 at 281, DirectX 10 at 141, DirectX 9 at 343, and DirectX 12 at 74. PassMark GPU Compute scores 14,737, and PassMark G2D scores 1,280. The pattern suggests that the RX 9070 excels in contemporary compute and graphics workloads, with older API tests being less representative of its design priorities.

The Verdict

The data positions these two products in completely separate markets. The AMD Radeon RX 9070 is a client graphics card with full API support, a complete display output suite, and measurable benchmark scores across 3DMark, Geekbench, and PassMark tests. Its average benchmark score of 23,877 and 69th percentile rank place it among capable desktop graphics solutions, with nearest rivals like the RTX 2080 SUPER and RX 6800S within roughly 1% of its average score. It targets users who need rasterization, ray tracing, and compute through standard graphics interfaces.

The NVIDIA H20 is a server accelerator with no display outputs, no graphics API support, and no recorded benchmarks. Its design centers on massive memory capacity, extremely high bandwidth, and tensor core compute, with FP16 throughput of 79.07 TFLOPS at a 2:1 ratio versus FP32. The 96 GB HBM3 memory and 4.03 TB/s bandwidth indicate workloads involving large datasets that do not fit in conventional GPU memory. Its 50th percentile rank reflects the absence of graphics tests rather than performance in its intended domain.

For anyone selecting between these two, the choice is dictated by workload. The RX 9070 is the only option for rendering to a display, running DirectX or Vulkan applications, or performing graphics-API compute. The H20 is the only option for server deployments requiring high-bandwidth memory and tensor operations, but its lack of benchmarks means the database cannot quantify its graphics performance. The RX 9070 wins every recorded benchmark comparison, but that is because the benchmark suite does not cover the H20's specialized capabilities. The verdict from the data is straightforward: the RX 9070 for graphics, the H20 for memory-bound server compute, with no overlap between their respective strengths.
