AMD Radeon RX 7600 XT vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark results for the AMD Radeon RX 7600 XT and the NVIDIA H20. The head-to-head benchmark array is empty, and the win counts for both parts are zero. Consequently, no direct performance comparison can be drawn from identical test conditions.

The AMD Radeon RX 7600 XT has a full benchmark suite, with its strongest showing in PassMark G3D at 17,132 points. Its average benchmark score across all recorded tests is 17,083, placing it at the 60th percentile of all GPUs in the database. The NVIDIA H20, by contrast, has no benchmark entries at all, an average benchmark score of 0, and sits at the 50th percentile. This means the H20's database record is entirely unmeasured on the standard GPU test battery, which prevents any direct numerical comparison of gaming or compute performance.

The RX 7600 XT's nearest rivals in the database provide context for its standing. It trails the NVIDIA GeForce RTX 3070 by 0.7% in average score (17,208 versus 17,083), a negligible gap. It leads the NVIDIA GeForce GTX 690 by 0.3% (17,037), the AMD Radeon HD 7970M by 0.4% (17,019), and the NVIDIA Tesla M4 by 0.9% (16,932). These deltas are all within roughly one percentage point, indicating that the RX 7600 XT's average benchmark performance clusters tightly with this group of older and mid-range parts.

Individual benchmark scores for the RX 7600 XT show a wide spread across test types. In Geekbench OpenCL it records 92,426 points, while Geekbench Vulkan produces 48,366. The 3DMark Steel Nomad DX12 test yields 2,348 points. PassMark results vary from 228 in DirectX 9, 167 in DirectX 11, 85 in DirectX 10, and 65 in DirectX 12, alongside 17,132 in G3D, 8,987 in GPU compute, and 1,030 in G2D. These figures indicate the card performs substantially better in compute-oriented OpenCL workloads than in legacy DirectX rasterization tests, though the absence of H20 data means no relative judgment is possible.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The AMD Radeon RX 7600 XT uses the Navi 33 chip built on RDNA 3.0, with the codename Hotpink Bonefish, and belongs to the Navi III (RX 7000) generation. The NVIDIA H20 uses the GH100 chip built on Hopper, belongs to the Server Hopper (Hxx) generation, and has no codename recorded. Their process nodes differ as well: the RX 7600 XT is fabricated on a 6 nm process at TSMC, while the H20 uses a 5 nm process at the same foundry.

Transistor counts diverge dramatically. The RX 7600 XT packs 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The H20 contains 80,000 million transistors on an 814 mm² die, with a density of 98.3M per mm². The H20 therefore has roughly six times the transistor count and a substantially higher density, consistent with its server-class positioning.

Compute resources differ in structure. The RX 7600 XT has 2,048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. It has no tensor cores recorded. The H20 has 9,984 shading units, 312 TMUs, only 24 ROPs, and 312 tensor cores, with no ray tracing cores recorded. The H20's ROP count is notably lower than the RX 7600 XT's despite its far larger shading unit count, indicating a design aimed at compute throughput rather than pixel output. Indeed, pixel rates confirm this: the RX 7600 XT reaches 176.3 GPixel/s, while the H20 manages 47.52 GPixel/s. Texture rates reverse the order, with the H20 at 617.8 GTexel/s versus the RX 7600 XT's 352.6 GTexel/s.

Floating-point performance shows the H20's compute advantage. The RX 7600 XT delivers 22.57 TFLOPS for both FP32 and FP16, with a 1:1 ratio. The H20 delivers 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16, with a 2:1 ratio. The H20 is therefore 75% ahead in FP32 and roughly 3.5 times ahead in FP16, reflecting its tensor-heavy Hopper design.

The memory architectures are fundamentally different. The RX 7600 XT uses 16 GB of GDDR6 on a 128-bit interface, producing 288.0 GB/s of bandwidth. The H20 uses 96 GB of HBM3 on a 6144-bit interface, producing 4.03 TB/s, which is roughly 14 times the bandwidth. The H20's memory clock is listed at 1313 MHz (5.3 Gbps effective), compared to the RX 7600 XT's 2250 MHz (18 Gbps effective), but the massive bus width makes the H20's bandwidth far superior.

Specification Differences

The RX 7600 XT is a dual-slot consumer card with a length of 204 mm (8 inches) and a height of 115 mm (4.5 inches). It uses a single 8-pin power connector and a suggested PSU of 450 W, with a TDP of 190 W. Its bus interface is PCIe 4.0 x8, and it offers display outputs of 1x HDMI 2.1a and 3x DisplayPort 2.1. Its base clock is 1980 MHz, game clock 2470 MHz, and boost clock 2755 MHz.

The H20 is an SXM module with no recorded dimensions, no power connector listed, and a suggested PSU of 900 W. Its TDP is 500 W. It uses a PCIe 5.0 x16 interface and has no display outputs. Its base clock is 1830 MHz and boost clock 1980 MHz, with no game clock recorded. The H20's API support is entirely N/A for DirectX, OpenGL, and Vulkan, while the RX 7600 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Both cards are marked as Active in production status. The RX 7600 XT was released on 2024-01-23, with a launch MSRP of 329 USD, and its predecessor is Navi II while its successor is Navi IV. The H20 was released on 2024-01-31, with no launch MSRP recorded, and its predecessor is Server Ada while its successor is Server Blackwell.

Where Each One Wins

The AMD Radeon RX 7600 XT wins in every category where actual benchmark data exists, simply because the NVIDIA H20 has no recorded scores. In the database, the RX 7600 XT holds a 60th percentile ranking, an average benchmark score of 17,083, and a full set of PassMark, Geekbench, and 3DMark results. The H20's 50th percentile with zero average score is purely a placeholder, not a measured outcome.

For rasterization and pixel output, the RX 7600 XT is the clear leader. Its 176.3 GPixel/s pixel rate dwarfs the H20's 47.52 GPixel/s, and its 64 ROPs compare favorably to the H20's 24. The RX 7600 XT also supports consumer display outputs, DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it usable in gaming and workstation environments that require those APIs. The H20 offers no display outputs and no consumer API support.

The NVIDIA H20 wins on raw compute capacity and memory bandwidth. Its 39.54 TFLOPS FP32 is 75% above the RX 7600 XT's 22.57 TFLOPS, and its 79.07 TFLOPS FP16 is roughly 3.5 times higher. The H20's 4.03 TB/s memory bandwidth is about 14 times the RX 7600 XT's 288.0 GB/s, and its 96 GB of HBM3 capacity is six times larger. The H20 also has 312 tensor cores, which the RX 7600 XT lacks entirely, positioning it for matrix and AI workloads.

Use-case separation follows these strengths. The RX 7600 XT suits conventional graphics tasks: gaming, DirectX-based rendering, and any workload requiring display output or Vulkan support. Its higher pixel rate and ROP count make it better suited to frame generation. The H20 suits server-side compute: large memory footprints, high-bandwidth data movement, and FP16 or tensor operations. Its lack of display outputs and graphics APIs eliminates it from client-side rendering roles.

The database's nearest rival data for the RX 7600 XT shows how tightly it clusters with prior-generation parts. It is 0.7% behind the RTX 3070, 0.3% ahead of the GTX 690, 0.4% ahead of the HD 7970M, and 0.9% ahead of the Tesla M4. This suggests the RX 7600 XT's performance level is well established, whereas the H20's absence from the benchmark suite leaves its performance entirely uncharacterized. The H20's 50th percentile, despite having no scores, likely reflects its classification as a server part rather than any measured capability.

In summary, the RX 7600 XT is the only one of the two with measurable graphics performance, while the H20 excels in theoretical compute specifications. Each card wins in its intended domain: consumer graphics for the RX 7600 XT, server compute for the H20.
