AMD Radeon RX 9070 GRE vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Radeon RX 9070 GRE and the NVIDIA H20. The H20 has no benchmark entries at all, while the RX 9070 GRE has two recorded scores: a 3DMark Steel Nomad DX12 result of 5424 points and a Geekbench OpenCL score of 109309. The H20 holds a percentile rank of 50 among all GPUs, while the RX 9070 GRE sits at the 87th percentile. The RX 9070 GRE shows an average benchmark score of 57367, whereas the H20 has an average score of 0, reflecting the absence of submitted results.

Looking at the RX 9070 GRE's nearest rivals in the database, it trails the Intel Arc A580 by 0.7%, the AMD Radeon RX 5600 OEM by 1.2%, the Intel Arc A570M by 1.5%, and the AMD Radeon RX 6950 XT by 1.8%. These deltas are small, placing the RX 9070 GRE within a tight performance band around those cards. The H20 has no nearest rivals listed, so no comparative percentage deltas exist for it.

The RX 9070 GRE's 3DMark Steel Nomad score of 5424 reflects its DirectX 12 Ultimate capability, while the Geekbench OpenCL score of 109309 indicates strong compute throughput in that specific workload. The H20's lack of any benchmark data means the database cannot quantify its rasterization or compute performance relative to the RX 9070 GRE. Any attempt to compare their real-world speeds would require additional measurements that are not present in the current records.

Where Each One Wins

Based on the available data, the AMD Radeon RX 9070 GRE wins in every measurable category simply because it has recorded benchmarks and the NVIDIA H20 has none. The RX 9070 GRE delivers 34.28 TFLOPS of FP32 performance and an identical 34.28 TFLOPS of FP16 performance with a 1:1 ratio, making it a balanced compute device for workloads that do not heavily favor reduced precision. Its 267.8 GPixel/s pixel rate and 535.7 GTexel/s texture rate indicate strong fill performance for traditional graphics rendering.

The NVIDIA H20, by contrast, shows a different design intent. It offers 39.54 TFLOPS of FP32 and 79.07 TFLOPS of FP16 with a 2:1 ratio, meaning its FP16 throughput is double its FP32 rate. This asymmetry points toward AI and deep learning inference workloads where reduced precision is the standard. The H20 also carries 312 tensor cores, a feature the RX 9070 GRE does not list at all. The RX 9070 GRE includes 48 ray tracing cores, while the H20 lists no RT cores, suggesting the H20 is not aimed at real-time ray-traced gaming.

In gaming and DirectX workloads, the RX 9070 GRE has the clear advantage. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the H20 lists no graphics API support at all. The RX 9070 GRE also has display outputs (1x HDMI 2.1b and 3x DisplayPort 2.1a), whereas the H20 has no outputs, reinforcing that the H20 is a compute-only accelerator. For any use case involving a monitor, the RX 9070 GRE is the only option between the two.

The H20 wins in memory capacity and bandwidth. It carries 96 GB of HBM3 across a 6144-bit bus, delivering 4.03 TB/s of bandwidth. The RX 9070 GRE has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s. The H20's memory subsystem is nearly ten times larger in capacity and roughly nine times faster in bandwidth, making it suited for large models or datasets that exceed the RX 9070 GRE's memory envelope.

Architecture Differences

The AMD Radeon RX 9070 GRE uses the Navi 48 chip built on RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. It contains 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0 million per mm². The NVIDIA H20 uses the GH100 chip with Hopper architecture, also from TSMC but on a 5 nm process. It packs 80,000 million transistors across an 814 mm² die, with a density of 98.3 million per mm². The H20's die is more than twice the physical size of the RX 9070 GRE's, and it holds roughly 48% more transistors, though at lower density due to the older process node.

Clock behavior differs substantially. The RX 9070 GRE runs a base clock of 1420 MHz, a boost clock of 2790 MHz, and a game clock of 2220 MHz. The H20 operates at a base of 1830 MHz and a boost of 1980 MHz, with no game clock listed. The RX 9070 GRE's boost clock is over 800 MHz higher than the H20's, reflecting its graphics-oriented design. Memory clocks also diverge: the RX 9070 GRE's GDDR6 runs at 2250 MHz (18 Gbps effective), while the H20's HBM3 runs at 1313 MHz (5.3 Gbps effective), though the H20 compensates with its massive bus width.

Shader and texture resources differ sharply. The RX 9070 GRE has 3072 shading units, 192 TMUs, and 96 ROPs. The H20 has 9984 shading units, 312 TMUs, and only 24 ROPs. The H20's higher shading unit count drives its FP32 throughput, but its low ROP count limits pixel output to 47.52 GPixel/s compared to the RX 9070 GRE's 267.8 GPixel/s. Texture rate favors the H20 at 617.8 GTexel/s versus 535.7 GTexel/s for the RX 9070 GRE. The H20 also has 312 tensor cores, while the RX 9070 GRE lists none. The RX 9070 GRE has 48 ray tracing cores; the H20 has none listed.

Power and cooling requirements reflect their different roles. The RX 9070 GRE has a TDP of 220 W, uses dual-slot cooling, requires 2x 8-pin power connectors, and a suggested 550 W PSU. The H20 is an SXM module with a 500 W TDP and a suggested 900 W PSU, with no power connector details listed because it likely draws power through its socket interface. The RX 9070 GRE connects via PCIe 5.0 x16, and so does the H20, but the H20 has no display outputs while the RX 9070 GRE offers HDMI and DisplayPort.

Release timing also separates them. The H20 launched on 2024-01-31, while the RX 9070 GRE launched on 2025-05-07. The H20's predecessor is Server Ada and its successor is Server Blackwell. The RX 9070 GRE's predecessor is Navi III, and it has no successor listed.

The Verdict

The data indicates two entirely different product categories. The AMD Radeon RX 9070 GRE is a consumer graphics card with display outputs, ray tracing cores, full graphics API support, and a 220 W power envelope. It scores at the 87th percentile among all GPUs, with an average benchmark score of 57367. It is designed for gaming and general graphics workloads where DirectX, Vulkan, and OpenGL matter, and where a monitor needs to be connected.

The NVIDIA H20 is a server accelerator with no display outputs, no graphics API support, no ray tracing cores, and a 500 W power envelope. It sits at the 50th percentile, but that rank comes from no recorded benchmarks, so the percentile should not be interpreted as a performance statement. Its 96 GB of HBM3 and 4.03 TB/s bandwidth, combined with 312 tensor cores and 79.07 TFLOPS of FP16 throughput, point to large-scale compute tasks such as AI inference or high-performance computing where memory capacity and reduced-precision math dominate.

For a buyer assembling a gaming PC or a workstation with visual output needs, the RX 9070 GRE is the only viable choice. It delivers playable DirectX 12 performance, supports modern display interfaces, and fits in a standard dual-slot PCIe card. The H20 cannot be used in such a system because it has no display outputs and no graphics drivers for standard APIs.

For a data center operator running machine learning models that exceed 12 GB of memory, the H20 is the practical pick. Its 96 GB capacity and 4.03 TB/s bandwidth allow it to hold far larger working sets than the RX 9070 GRE's 12 GB GDDR6. Its FP16 throughput of 79.07 TFLOPS is more than double the RX 9070 GRE's 34.28 TFLOPS, and its tensor cores provide dedicated hardware for neural network operations.

The RX 9070 GRE's launch MSRP is 549 USD. No such figure exists for the H20 in the database.
