Both use RDNA 2.0 architecture, but the process nodes differ: the Radeon part is built on a 6 nm process at TSMC, while the Ryzen Z2 A GPU uses a 7 nm process at TSMC. Transistor counts differ substantially, with the Radeon RX 6550M containing 5,400 million transistors compared to 2,400 million in the Ryzen Z2 A GPU. The die sizes are 107 mm² for the Radeon part and 163 mm² for the Ryzen part, meaning the Radeon chip packs more transistors into a smaller area, yielding a transistor density of 50.5 million per mm² versus 14.7 million per mm².

Clock speeds show significant divergence. The Radeon RX 6550M has a base clock of 2000 MHz, a boost clock of 2840 MHz, and a game clock of 2560 MHz. The Ryzen Z2 A GPU has a base clock of 1000 MHz and a boost clock of 1600 MHz, with no game clock recorded. Memory clocks also differ: the Radeon part runs at 2250 MHz with 18 Gbps effective, while the Ryzen Z2 A GPU runs at 800 MHz with 6.4 Gbps effective.

Memory configurations are markedly different. The Radeon RX 6550M has 4 GB of GDDR6 on a 64-bit bus with 144.0 GB/s bandwidth. The Ryzen Z2 A GPU has 16 GB of LPDDR5 on a 128-bit bus with 102.4 GB/s bandwidth. The Radeon part has more memory bandwidth despite a narrower bus, while the Ryzen part has four times the capacity.

Compute unit counts differ across all categories. The Radeon RX 6550M has 1024 shading units, 64 texture mapping units, 32 raster output units, and 16 ray tracing cores. The Ryzen Z2 A GPU has 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. The Radeon part doubles the Ryzen part in every compute resource category.

Pixel and texture rates reflect these differences. The Radeon RX 6550M achieves 90.88 GPixel/s and 181.8 GTexel/s, while the Ryzen Z2 A GPU achieves 25.60 GPixel/s and 51.20 GTexel/s. Floating point performance shows a similar gap: the Radeon part delivers 5.816 TFLOPS FP32 and 11.63 TFLOPS FP16, while the Ryzen part delivers 1.638 TFLOPS FP32 and 3.277 TFLOPS FP16.

Power requirements differ sharply. The Radeon RX 6550M has an 80 W TDP, no power connectors required, and an IGP slot width. The Ryzen Z2 A GPU has a 15 W TDP with no power connector or slot width data recorded. The Radeon part uses PCIe 4.0 x4 as its bus interface, while the Ryzen part has no bus interface recorded. Display outputs also differ: the Radeon part is portable device dependent, while the Ryzen part has 1x USB Type-C.

Release dates differ by nearly two years. The Radeon RX 6550M was released on January 3, 2023, while the Ryzen Z2 A GPU was released on December 31, 2024. The Radeon part lists its predecessor as Polaris Mobile, while the Ryzen part has no predecessor recorded. Both parts are listed as Active in production status.

Architecture Differences

Both GPUs use RDNA 2.0 architecture from AMD, but they serve different market segments. The Radeon RX 6550M belongs to the Radeon RX 6000 series under the Navi Mobile generation, while the Ryzen Z2 A GPU is classified under Console GPU (AMD) generation. The Radeon part uses the Navi 24 chip, and the Ryzen part uses the Van Gogh chip.

The process technology gap is notable. The Radeon RX 6550M uses a 6 nm process at TSMC, which is more advanced than the 7 nm process used by the Ryzen Z2 A GPU at the same foundry. The transistor density difference of 50.5 million per mm² versus 14.7 million per mm² indicates the Radeon part benefits from a more compact process node that allows higher integration density.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The API support is identical, meaning software compatibility is not a differentiating factor between the two parts. The ray tracing cores are present in both, with the Radeon part having 16 and the Ryzen part having 8, but the underlying architecture for ray tracing is the same RDNA 2.0 implementation.

The Radeon RX 6550M's memory subsystem uses dedicated GDDR6 memory on a 64-bit bus, which is typical for discrete-class GPUs. The Ryzen Z2 A GPU uses LPDDR5 memory on a 128-bit bus, which is characteristic of integrated or console-oriented designs where memory is shared with other system components. The Ryzen part's larger capacity of 16 GB suggests it handles system memory duties beyond graphics, consistent with a console GPU classification.

The Radeon RX 6550M has no tensor cores recorded, and neither does the Ryzen Z2 A GPU. Both parts rely on the same RDNA 2.0 compute architecture without dedicated AI acceleration hardware, according to the database records.

Power delivery differs in implementation. The Radeon RX 6550M requires no external power connectors and is designed as an IGP, meaning it draws power through the motherboard or integrated platform. The Ryzen Z2 A GPU has no power connector data recorded, but its 15 W TDP indicates a low-power design suitable for portable or embedded applications.

The display output configuration also reflects different use cases. The Radeon RX 6550M's outputs are portable device dependent, meaning the display connectivity depends on the host device. The Ryzen Z2 A GPU provides a single USB Type-C output, which can carry display signals alongside data and power.

The Verdict

The data presents a clear performance hierarchy. The AMD Radeon RX 6550M has measured benchmark scores that place it in the 85th percentile of all GPUs, with an average score of 46702 and the highest individual result of 50867 in Geekbench Vulkan. Its nearest rivals trail by margins of 0.2 to 1.6 percent, confirming its position at the top of its immediate competitive cluster.

The AMD Ryzen Z2 A GPU has no recorded benchmarks, so no performance verdict can be derived from measurements. Its 50th percentile ranking and zero average score indicate the absence of data rather than a measured performance level. The specifications show a lower-power part with half the shading units, TMUs, ROPs, and ray tracing cores of the Radeon RX 6550M, along with lower clock speeds and reduced compute throughput.

For workloads that require graphics compute, the Radeon RX 6550M is the only part with verifiable performance data. It delivers 5.816 TFLOPS FP32, which is approximately 3.55 times the 1.638 TFLOPS of the Ryzen Z2 A GPU. Its memory bandwidth of 144.0 GB/s exceeds the Ryzen part's 102.4 GB/s by roughly 40.6 percent. The Radeon part's pixel rate of 90.88 GPixel/s is 3.55 times the Ryzen part's 25.60 GPixel/s.

The Ryzen Z2 A GPU offers a different trade-off. Its 16 GB memory capacity is four times that of the Radeon RX 6550M, and its 15 W TDP is 18.75 percent of the Radeon part's power draw. These specifications suggest a design focused on memory capacity and power efficiency rather than raw graphics throughput.

The database supports a straightforward selection criterion. Users who need measured graphics performance should consider the Radeon RX 6550M, as it has benchmark results demonstrating capability in the 85th percentile. Users who need a low-power part with substantial memory capacity and no requirement for recorded performance data would look to the Ryzen Z2 A GPU, but they should recognize that no benchmark evidence exists to validate its performance level. The Radeon RX 6550M holds the only verified performance position in this comparison.
