AMD Radeon RX 7650 GRE vs NVIDIA H20 Comparison

The Verdict

The AMD Radeon RX 7650 GRE and NVIDIA H20 occupy completely separate corners of the GPU market, and the recorded data reflects that split clearly. The RX 7650 GRE is a desktop gaming card with an active production status, a 170 W TDP, and a dual-slot 204 mm form factor with display outputs. The H20 is a server accelerator with a 500 W TDP, an SXM module slot, and no display outputs at all. There is no overlap in use cases.

The Radeon RX 7650 GRE posts a percentile rank of 83 against all GPUs in the database, with an average benchmark score of 42723. It trails the NVIDIA GeForce RTX 4070 SUPER by just 1.2% in average score, which places it in the upper tier of consumer graphics cards. The H20, by contrast, has a percentile rank of 50 and an average benchmark score of 0, with no recorded benchmark entries. The H20 is not a card you would pick for rasterization or gaming; the data shows it lacks DirectX, OpenGL, and Vulkan support entirely. The RX 7650 GRE is the obvious choice for any graphics workload, while the H20 is defined by its compute-oriented specifications rather than measured graphics performance.

The verdict is simple: the RX 7650 GRE is for gamers and desktop workstation users who need a capable single-slot-width card with modern display outputs. The H20 is for server deployments where 96 GB of HBM3 memory and 4.03 TB/s of bandwidth matter more than raw graphics throughput. The launch MSRP of the RX 7650 GRE is 279 USD. The H20 has no recorded launch MSRP, and the database shows it as a server part without display connectivity.

Architecture Differences

The two chips come from different foundries and process nodes. The RX 7650 GRE uses the Navi 33 chip on TSMC's 6 nm process, with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2M per mm². The H20 uses the GH100 chip on TSMC's 5 nm process, with 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3M per mm². The H20's die is roughly four times larger and packs six times the transistors.

Architecturally, the RX 7650 GRE is built on RDNA 3.0 with the codename "Hotpink Bonefish," part of the Navi III (RX 7000) generation. The H20 is built on Hopper architecture, part of the Server Hopper (Hxx) generation. The RX 7650 GRE supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H20 reports N/A for all three graphics APIs. That is a fundamental split: one chip is designed to render frames, the other is not.

The RX 7650 GRE has 2048 shading units, 128 TMUs, 64 ROPs, and 32 dedicated ray tracing cores, with no tensor cores listed. The H20 has 9984 shading units, 312 TMUs, 24 ROPs, and 312 tensor cores, with no ray tracing cores listed. The H20's pixel rate is 47.52 GPixel/s, which is lower than the RX 7650 GRE's 172.5 GPixel/s, but its texture rate is 617.8 GTexel/s versus 345.0 GTexel/s for the AMD card. The H20 is built for compute throughput, not pixel pushing.

Where Each One Wins

The RX 7650 GRE wins in every measured graphics benchmark, simply because the H20 has no recorded benchmarks. The database shows the AMD card scoring 2336 in 3DMark Steel Nomad DX12 and 83109 in Geekbench OpenCL. The H20's benchmark list is empty, so there is no direct head-to-head data.

In practical terms, the RX 7650 GRE wins where display output matters. It has 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, while the H20 has no outputs. The RX 7650 GRE also wins on power efficiency for typical desktop loads, with a 170 W TDP and a suggested PSU of 450 W, versus the H20's 500 W TDP and 900 W suggested PSU. The AMD card fits in a 204 mm length, 115 mm height, dual-slot footprint, whereas the H20 is an SXM module with no listed dimensions.

The H20 wins where memory capacity and bandwidth dominate. It has 96 GB of HBM3 memory on a 6144-bit bus with 4.03 TB/s bandwidth. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth. The H20 also has more shading units (9984 vs 2048), more TMUs (312 vs 128), and more tensor cores (312 vs none). For FP16 compute, the H20 delivers 79.07 TFLOPS at a 2:1 ratio, while the RX 7650 GRE delivers 22.08 TFLOPS at 1:1. The H20's FP32 of 39.54 TFLOPS is nearly double the RX 7650 GRE's 22.08 TFLOPS.

Head-to-Head Benchmarks

There are no direct head-to-head benchmark entries in the database, so the comparison relies on the individual scores and specifications. The RX 7650 GRE's 3DMark Steel Nomad DX12 score of 2336 is a measurable graphics result; the H20 has none. The RX 7650 GRE's Geekbench OpenCL score of 83109 is a compute result; the H20 has none.

The closest comparison comes from the RX 7650 GRE's nearest rivals, which show it within 1.3% of several NVIDIA parts. It trails the RTX 4070 SUPER by 1.2% (43223 vs 42723), the Quadro M6000 24 GB by 1.2% (43262 vs 42723), the RTX 5050 Mobile by 1.3% (43268 vs 42723), and the Quadro M6000 by 1.3% (43301 vs 42723). This places the RX 7650 GRE in a tight competitive band among desktop and mobile GPUs, but the H20 is not in that band at all.

The H20's advantage is purely on paper. Its 4.03 TB/s memory bandwidth is 14 times the RX 7650 GRE's 288.0 GB/s. Its 96 GB memory capacity is 12 times larger. Its 9984 shading units are nearly five times the RX 7650 GRE's 2048. These are the numbers that define a server accelerator, not a graphics card. For any workload that relies on FP32 or FP16 throughput, the H20's 39.54 TFLOPS and 79.07 TFLOPS respectively dwarf the RX 7650 GRE's 22.08 TFLOPS on both counts.
