AMD Radeon RX 6550M vs NVIDIA H20 NVL16 Comparison

The AMD Radeon RX 6550M and the NVIDIA H20 NVL16 occupy opposite ends of the hardware spectrum. The RX 6550M is a compact mobile graphics solution built on RDNA 2.0, while the H20 NVL16 is a massive server accelerator based on the Hopper architecture. Direct benchmark comparisons between the two are unavailable in the database, as the H20 NVL16 has no recorded benchmark scores, while the RX 6550M has two recorded results. This analysis relies on the available specifications and the RX 6550M’s recorded performance data to outline where each part stands.

The Verdict

The data indicates that these two products are not direct competitors. The RX 6550M is designed for portable devices, with an integrated form factor (IGP slot width), no power connectors, and a 80 W thermal design power. It targets mobile gaming and general graphics workloads, as evidenced by its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The H20 NVL16, by contrast, is a server module with a 400 W thermal design power, a suggested power supply rating of 800 W, and no display outputs. It is built for compute-heavy server environments, not for rendering frames to a screen.

For users selecting a mobile GPU for a laptop, the RX 6550M is the only viable option between the two, as the H20 NVL16 is not designed for client devices. For data center operators requiring massive memory capacity and tensor processing, the H20 NVL16 is the clear choice, given its 96 GB HBM3 memory and 312 tensor cores. The RX 6550M has no tensor cores listed, making it unsuitable for the accelerated AI workloads the H20 NVL16 is configured to handle. The verdict is straightforward: each part serves a different market, and neither can substitute for the other in its respective domain.

Where Each One Wins

The RX 6550M wins in scenarios requiring compact integration and graphics output. Its portable device dependent display outputs and integrated form factor allow it to fit into thin laptops. It also wins on clock speeds, with a boost clock of 2840 MHz and a game clock of 2560 MHz, both higher than the H20 NVL16’s boost clock of 1980 MHz. In raw pixel throughput, the RX 6550M delivers 90.88 GPixel/s, nearly double the 47.52 GPixel/s of the H20 NVL16. This makes the RX 6550M the winner for traditional rasterization tasks where pixel fill rate matters.

The H20 NVL16 wins decisively in memory capacity and bandwidth. Its 96 GB HBM3 memory dwarfs the RX 6550M’s 4 GB GDDR6, and its bandwidth of 4.03 TB/s is roughly 28 times the 144.0 GB/s available on the RX 6550M. The bus width difference is enormous: 6144 bit versus 64 bit. For data sets that exceed 4 GB, the H20 NVL16 is the only option. It also wins on raw compute throughput, with 39.54 TFLOPS FP32 performance against 5.816 TFLOPS for the RX 6550M, and 79.07 TFLOPS FP16 performance against 11.63 TFLOPS. The H20 NVL16 has 312 tensor cores, a feature entirely absent from the RX 6550M’s specification sheet.

Architecture Differences

The two GPUs come from different architectural lineages. The RX 6550M uses the Navi 24 chip built on RDNA 2.0, a 6 nm process from TSMC. It integrates 5,400 million transistors on a die size of 107 mm², resulting in a transistor density of 50.5 million per mm². The H20 NVL16 uses the GH100 chip built on Hopper architecture, fabricated on a 5 nm process, also from TSMC. This chip contains 80,000 million transistors on a much larger 814 mm² die, with a density of 98.3 million per mm². The H20 NVL16 has roughly 15 times the transistor count and a die over 7.6 times larger.

Memory architecture differs fundamentally. The RX 6550M uses 4 GB of GDDR6 on a 64-bit bus, with memory clocked at 2250 MHz and an effective data rate of 18 Gbps, yielding 144.0 GB/s bandwidth. The H20 NVL16 uses 96 GB of HBM3 on a 6144-bit bus, with memory clocked at 1313 MHz and an effective rate of 5.3 Gbps, producing 4.03 TB/s bandwidth. The H20 NVL16’s memory subsystem is in a different class entirely, suited for workloads with large memory footprints.

Compute resources also differ sharply. The RX 6550M has 1024 shading units, 64 texture mapping units, 32 raster operation units, and 16 ray tracing cores, with no tensor cores. The H20 NVL16 has 9984 shading units, 312 texture mapping units, 24 raster operation units, and 312 tensor cores, with no dedicated ray tracing cores listed. The H20 NVL16 has nearly ten times the shading units and over four times the texture mapping units, but fewer raster operation units. The RX 6550M supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4; the H20 NVL16 lists N/A for all those APIs, reflecting its server-oriented design with no display outputs.

Other differences include bus interface and power delivery. The RX 6550M uses PCIe 4.0 x4, while the H20 NVL16 uses PCIe 5.0 x16. The H20 NVL16 is an SXM module, whereas the RX 6550M is integrated. The RX 6550M has a base clock of 2000 MHz, while the H20 NVL16 has a base clock of 1830 MHz. The RX 6550M’s transistor density of 50.5M per mm² is lower than the H20 NVL16’s 98.3M per mm², indicating a denser packing on the Hopper chip.

Head-to-Head Benchmarks

There are no direct head-to-head benchmark results recorded between the RX 6550M and the H20 NVL16. The H20 NVL16 has an empty benchmark array, and the head-to-head field contains no entries. The RX 6550M’s recorded scores can be interpreted against its own percentile and nearest rivals, but no cross-comparison with the H20 NVL16 is possible from the data.

The RX 6550M achieves a percentile rank of 85 among all GPUs, with an average benchmark score of 46702. Its nearest rivals in the database include the Intel Arc A530M with an average score of 46614 (a 0.2 percent difference), the AMD Radeon RX 5600M with an average score of 46601 (0.2 percent difference), the NVIDIA RTX A2000 with an average score of 46043 (1.4 percent difference), and the NVIDIA RTX 5880 Ada Generation with an average score of 45972 (1.6 percent difference). This places the RX 6550M slightly ahead of all four in average score, but by a very narrow margin.

The largest recorded win for the RX 6550M is in the Geekbench Vulkan test, where it scores 50867, which is higher than its OpenCL score of 42536. The average benchmark score of 46702 sits between these two values. Since the H20 NVL16 has no scores, the only quantitative comparison available is between the RX 6550M’s numbers and its nearest rivals, none of which is the H20 NVL16.

Given the absence of H20 NVL16 benchmark data, the performance comparison must rely on specification-level differences. The H20 NVL16’s FP32 throughput of 39.54 TFLOPS is 6.8 times the RX 6550M’s 5.816 TFLOPS. Its FP16 throughput of 79.07 TFLOPS is 6.8 times the RX 6550M’s 11.63 TFLOPS. The H20 NVL16’s texture rate of 617.8 GTexel/s is 3.4 times the RX 6550M’s 181.8 GTexel/s. However, the RX 6550M’s pixel rate of 90.88 GPixel/s is 1.9 times the H20 NVL16’s 47.52 GPixel/s.

The RX 6550M’s nearest rival comparisons show how tightly packed the mid-range mobile market is. The Intel Arc A530M is only 0.2 percent behind, and the AMD Radeon RX 5600M is also 0.2 percent behind. The NVIDIA RTX A2000 trails by 1.4 percent, and the RTX 5880 Ada Generation trails by 1.6 percent. These deltas indicate that the RX 6550M sits at the top of this small cluster, but the margins are small enough to be within run-to-run variance.

In terms of memory bandwidth, the H20 NVL16’s 4.03 TB/s is approximately 28 times the RX 6550M’s 144.0 GB/s. The H20 NVL16’s memory capacity of 96 GB is 24 times the RX 6550M’s 4 GB. These are the starkest differences between the two parts, and they define the intended use cases. The RX 6550M’s smaller memory and lower power envelope suit it for client devices, while the H20 NVL16’s vast memory and high power budget suit it for server acceleration.

The architectural data reinforces the separation. The H20 NVL16’s 5 nm process node is smaller than the RX 6550M’s 6 nm node, and its 98.3M transistors per mm² is nearly double the RX 6550M’s 50.5M per mm². The RX 6550M has a higher base clock (2000 MHz versus 1830 MHz) and a much higher boost clock (2840 MHz versus 1980 MHz), but the H20 NVL16 compensates with far more shading units (9984 versus 1024) and tensor cores (312 versus none). The RX 6550M has 16 ray tracing cores, while the H20 NVL16 lists none, and the RX 6550M supports graphics APIs that the H20 NVL16 does not. The production status for both is listed as Active, with the RX 6550M released on January 3, 2023, and the H20 NVL16 released on September 1, 2025.
