AMD Radeon RX 6550M vs NVIDIA H20 Comparison

FAQ

Q: What is the AMD Radeon RX 6550M's position in the overall GPU database?

A: The RX 6550M sits at the 85th percentile of all GPUs in the database, with an average benchmark score of 46702. Its nearest rival is the Intel Arc A530M, which scores 46614, a delta of only 0.2%.

Q: How does the NVIDIA H20 compare to the RX 6550M in the database standings?

A: The H20 is at the 50th percentile of all GPUs. It has no recorded benchmark scores, no average score, and no nearest rivals listed in the database, so its standing is based on specifications rather than measured performance data.

Q: What is the power draw of each GPU?

A: The RX 6550M has a TDP of 80 W and uses no external power connectors. The H20 has a TDP of 500 W, is an SXM Module, and the database lists a suggested PSU of 900 W.

Q: Do both GPUs support the same graphics APIs?

A: No. The RX 6550M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H20 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its server-oriented design with no display outputs.

The Verdict

The AMD Radeon RX 6550M is a mobile gaming GPU built for portable devices. The NVIDIA H20 is a server accelerator with no display outputs. The data shows two entirely different products with different design goals.

For clients seeking a GPU for gaming workloads in a laptop, the RX 6550M is the only viable option. It carries an active production status, supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it has measurable benchmark scores in the database. Its 85th percentile ranking places it ahead of the vast majority of GPUs, with a 1.4% edge over the NVIDIA RTX A2000 and a 1.6% edge over the NVIDIA RTX 5880 Ada Generation.

For compute-heavy server workloads, the H20 is the relevant choice. Its 96 GB of HBM3 memory with 4.03 TB/s of bandwidth, 9984 shading units, and 312 tensor cores position it as a high-capacity accelerator. The H20 has no recorded gaming benchmarks, no display outputs, and no graphics API support, which confirms it is not intended for client graphics use.

The two GPUs do not compete in the same market segment. The RX 6550M targets portable gaming systems within an 80 W envelope. The H20 targets server deployments with a 500 W TDP and a 900 W suggested PSU. Selection depends entirely on the workload: gaming and client graphics point to the RX 6550M, while large-scale compute points to the H20.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark comparisons between the RX 6550M and the H20. The RX 6550M has two recorded benchmark results: 42536 in Geekbench OpenCL and 50867 in Geekbench Vulkan. The H20 has no benchmark entries.

The RX 6550M's nearest rivals in the database provide context for its measured performance. It scores 46702 on average, which is 0.2% above the Intel Arc A530M at 46614 and 0.2% above the AMD Radeon RX 5600M at 46601. It sits 1.4% above the NVIDIA RTX A2000 at 46043 and 1.6% above the NVIDIA RTX 5880 Ada Generation at 45972.

The H20 has no recorded scores or rivals, so its performance can only be inferred from its specifications. Its FP32 output of 39.54 TFLOPS is substantially higher than the RX 6550M's 5.816 TFLOPS. Its texture rate of 617.8 GTexel/s exceeds the RX 6550M's 181.8 GTexel/s. The RX 6550M holds an advantage in pixel rate, delivering 90.88 GPixel/s versus the H20's 47.52 GPixel/s.

These figures align with the GPUs' roles. The RX 6550M's higher pixel rate suits rasterization-heavy graphics work. The H20's massive compute and texture throughput suits data center processing.

Specification Differences

The recorded specifications show clear divergence across nearly every category.

Architecture Differences

The RX 6550M uses the Navi 24 chip based on RDNA 2.0 architecture, part of the Navi Mobile generation within the Radeon RX 6000 series. It is manufactured by TSMC on a 6 nm process. The architecture includes 16 ray tracing cores, reflecting a client graphics focus.

The H20 uses the GH100 chip based on Hopper architecture, part of the Server Hopper generation. It is manufactured by TSMC on a 5 nm process. The architecture includes 312 tensor cores, reflecting a compute and AI focus. The H20 lists no ray tracing cores.

The cache hierarchy differs implicitly through the design: the RX 6550M carries the RDNA 2.0 feature set with DirectX 12 Ultimate support, while the H20 carries tensor core hardware and no graphics API support. The RX 6550M's 64-bit memory bus and 4 GB capacity suit a low-power mobile GPU. The H20's 6144-bit bus and 96 GB capacity suit large data center workloads.

The physical design differs as well. The RX 6550M is an integrated graphics package (IGP slot width) with no power connectors, designed to be embedded in portable devices. The H20 is an SXM Module, a board form factor for server installations, with a suggested PSU of 900 W.

The generational context also differs. The RX 6550M succeeds Polaris Mobile and remains active in production. The H20 succeeds Server Ada and is followed by Server Blackwell, also remaining active. The RX 6550M's 6 nm node with 5,400 million transistors on 107 mm² gives a density of 50.5M per mm². The H20's 5 nm node with 80,000 million transistors on 814 mm² gives a density of 98.3M per mm².

These architectural differences explain the benchmark and specification gaps. The RX 6550M is built for graphics rendering in mobile systems, with ray tracing cores and full DirectX 12 Ultimate support. The H20 is built for server compute, with tensor cores and no display path. The database records no head-to-head results between them, which is consistent with their separate market positions.
