Architecture Differences

The two GPUs come from different architecture generations. The AMD Radeon RX 6550M is built on RDNA 2.0 architecture with the Navi 24 chip, part of the Navi Mobile (RX 6000M) generation. The AMD Ryzen Z2 GPU uses RDNA 3.0 architecture with the Hawk Point chip, classified under the Console GPU (AMD) generation. This architectural shift from RDNA 2.0 to RDNA 3.0 brings changes in shader organization and feature support, although both maintain DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 in their API lists.

Manufacturing processes differ notably. The RX 6550M is fabricated on a 6 nm process at TSMC, while the Ryzen Z2 GPU uses a 4 nm process, also at TSMC. The transistor counts reflect this difference: the RX 6550M contains 5,400 million transistors on a 107 mm² die, yielding a transistor density of 50.5 million per mm². The Ryzen Z2 GPU packs 25,390 million transistors on a 178 mm² die, giving a density of 142.6 million per mm². The Ryzen Z2 GPU integrates far more transistors into a larger physical area with a much higher density.

Compute unit configurations differ as well. The RX 6550M has 1024 shading units, 64 texture mapping units, 32 ROPs, and 16 ray tracing cores. The Ryzen Z2 GPU has fewer shading units at 768, fewer texture units at 48, the same 32 ROPs, and fewer ray tracing cores at 12. Despite having fewer compute resources, the Ryzen Z2 GPU achieves a higher FP32 throughput of 8.294 TFLOPS compared to the RX 6550M's 5.816 TFLOPS. This result appears to stem from the architectural efficiency of RDNA 3.0 and the higher transistor density. FP16 performance also differs: the RX 6550M delivers 11.63 TFLOPS with a 2:1 ratio, while the Ryzen Z2 GPU delivers 8.294 TFLOPS with a 1:1 ratio.

Memory architecture is another major divergence. The RX 6550M uses discrete GDDR6 memory with 4 GB capacity, a 64-bit bus, and 144.0 GB/s bandwidth. The Ryzen Z2 GPU uses LPDDR5X memory with 16 GB capacity, a 128-bit bus, and 119.9 GB/s bandwidth. The Ryzen Z2 GPU has four times the capacity and double the bus width, but lower raw bandwidth due to the memory type. The RX 6550M has no power connectors and is listed with an IGP slot width, while the Ryzen Z2 GPU also has no power connectors and lists a single USB Type-C display output. The RX 6550M's display outputs are listed as portable device dependent.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 6550M and the Ryzen Z2 GPU. The head-to-head comparison table is empty, and neither GPU records a win in direct competition. This absence of direct measurement data means the comparison must rely on the separately recorded specifications and the benchmark scores available for the RX 6550M.

The RX 6550M has two recorded benchmark scores: a Geekbench OpenCL score of 42536 and a Geekbench Vulkan score of 50867. Its average benchmark score across these entries is 46702. The Ryzen Z2 GPU has no recorded benchmark scores in the database, with an average benchmark score of 0 and an empty nearest rivals list. Without direct measurements, the performance relationship between these two GPUs cannot be established from empirical benchmark data alone.

However, the recorded specifications provide a basis for inference. The RX 6550M shows a pixel rate of 90.88 GPixel/s and a texture rate of 181.8 GTexel/s. The Ryzen Z2 GPU shows a pixel rate of 86.40 GPixel/s and a texture rate of 129.6 GTexel/s. The RX 6550M leads in both pixel throughput and texture throughput, despite its lower FP32 figure. The higher FP32 throughput of the Ryzen Z2 GPU does not translate to higher pixel or texture rates in the recorded data. This suggests that the RX 6550M's higher clock speeds and dedicated memory bandwidth play a significant role in fill-rate-oriented workloads.

Clock behavior reinforces the separation. The RX 6550M has a base clock of 2000 MHz, a game clock of 2560 MHz, and a boost clock of 2840 MHz. The Ryzen Z2 GPU has a base clock of 800 MHz and a boost clock of 2700 MHz, with no game clock recorded. The RX 6550M runs at a much higher base frequency, which can sustain performance under sustained loads without relying on boost behavior. The Ryzen Z2 GPU's low base clock of 800 MHz suggests a power-saving design where the GPU ramps up to 2700 MHz under demand.

Specification Differences

The two GPUs differ across nearly every major specification field in the database. The process node is 6 nm for the RX 6550M versus 4 nm for the Ryzen Z2 GPU.

Clock speeds differ substantially. The 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 GPU has a base clock of 800 MHz and a boost clock of 2700 MHz, with no game clock listed. Memory clocks also differ: the RX 6550M runs at 2250 MHz with 18 Gbps effective, while the Ryzen Z2 GPU runs at 937 MHz with 7.5 Gbps effective.

Memory capacity, type, bus width, and bandwidth all differ. The RX 6550M has 4 GB GDDR6 on a 64-bit bus with 144.0 GB/s bandwidth. The Ryzen Z2 GPU has 16 GB LPDDR5X on a 128-bit bus with 119.9 GB/s bandwidth. The RX 6550M has 1024 shading units, 64 TMUs, 32 ROPs, and 16 ray tracing cores. The Ryzen Z2 GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores.

Compute rates differ as well. The RX 6550M achieves 90.88 GPixel/s pixel rate, 181.8 GTexel/s texture rate, 5.816 TFLOPS FP32, and 11.63 TFLOPS FP16 at a 2:1 ratio. The Ryzen Z2 GPU achieves 86.40 GPixel/s, 129.6 GTexel/s, 8.294 TFLOPS FP32, and 8.294 TFLOPS FP16 at a 1:1 ratio. TDP is 80 W for the RX 6550M and 28 W for the Ryzen Z2 GPU.

Release dates differ: the RX 6550M was released on 2023-01-03, and the Ryzen Z2 GPU on 2024-12-31. The RX 6550M lists its predecessor as Polaris Mobile. The Ryzen Z2 GPU has no predecessor recorded.

Where Each One Wins

The RX 6550M wins in pixel throughput with 90.88 GPixel/s versus 86.40 GPixel/s, a margin that favors it in rasterization-bound tasks. It also wins decisively in texture throughput with 181.8 GTexel/s versus 129.6 GTexel/s, indicating stronger fill-rate performance for textured workloads. Its memory bandwidth of 144.0 GB/s exceeds the Ryzen Z2 GPU's 119.9 GB/s, which helps in bandwidth-sensitive scenarios. The higher boost clock of 2840 MHz versus 2700 MHz, combined with a much higher base clock of 2000 MHz versus 800 MHz, gives the RX 6550M a sustained frequency advantage. The RX 6550M also has more shading units (1024 vs 768), more TMUs (64 vs 48), and more ray tracing cores (16 vs 12).

The Ryzen Z2 GPU wins in FP32 throughput with 8.294 TFLOPS versus 5.816 TFLOPS, a 2.478 TFLOPS advantage that indicates stronger raw compute capability for shader-heavy and general compute workloads. Its FP16 throughput of 8.294 TFLOPS matches its FP32 figure with a 1:1 ratio, whereas the RX 6550M's FP16 of 11.63 TFLOPS is higher in absolute terms but achieved through a 2:1 ratio. The Ryzen Z2 GPU also has 16 GB of memory versus 4 GB, four times the capacity, which matters for workloads with large working sets. Its 128-bit memory bus is double the width of the RX 6550M's 64-bit bus. The Ryzen Z2 GPU operates at 28 W TDP versus 80 W, making it far more power-efficient on paper. The 4 nm process with 142.6 million transistors per mm² versus 50.5 million per mm² indicates a denser, more modern implementation.

In terms of memory capacity and power consumption, the Ryzen Z2 GPU has clear advantages. The RX 6550M holds advantages in fill rate, memory bandwidth, and clock stability. The absence of benchmark data for the Ryzen Z2 GPU means its real-world performance cannot be verified against the RX 6550M's recorded scores, so these wins are based purely on specification comparisons.

The Verdict

The data indicates that the AMD Radeon RX 6550M is the only one of the two with recorded benchmark scores, achieving an average of 46702 points and ranking at the 85th percentile among all GPUs. Its nearest rivals in the database are all within 1.6% of its score, which places it in a tightly contested mid-range performance band. The Ryzen Z2 GPU has no benchmark scores, no nearest rivals, and a 50th percentile rank, which reflects its unverified status in the database rather than a measured performance level.

For applications that depend on pixel fill rate, texture throughput, and memory bandwidth, the RX 6550M shows the stronger specification profile. Its 90.88 GPixel/s and 181.8 GTexel/s exceed the Ryzen Z2 GPU's 86.40 GPixel/s and 129.6 GTexel/s. Its 144.0 GB/s bandwidth and 2840 MHz boost clock support these rates. The 80 W TDP suggests this GPU is designed for performance-oriented mobile systems.

For applications that depend on raw FP32 compute, memory capacity, and power efficiency, the Ryzen Z2 GPU shows the stronger specification profile. Its 8.294 TFLOPS FP32 exceeds the RX 6550M by a substantial margin. Its 16 GB memory capacity and 128-bit bus provide a larger memory footprint, and the 28 W TDP indicates a low-power design suited to compact devices. The 4 nm process and 142.6 million transistors per mm² reflect a newer manufacturing node.

The choice between the two depends on whether the workload prioritizes fill rate and bandwidth or compute throughput and memory capacity. The RX 6550M is the verified performer with measured scores, while the Ryzen Z2 GPU remains unmeasured in the database. Users with access to both should consider that the RX 6550M has empirical support for its performance claims, whereas the Ryzen Z2 GPU's advantages are purely specification-based at this time.
