AMD Radeon RX 6550M vs AMD Ryzen Z2 Go GPU Comparison

Head-to-Head Benchmarks

The database currently holds no direct head-to-head benchmark comparisons between the AMD Radeon RX 6550M and the AMD Ryzen Z2 Go GPU. The RX 6550M has recorded synthetic scores, while the Z2 Go GPU has no benchmark entries in the database at this time.

The RX 6550M posts a Geekbench OpenCL score of 42,536 and a Geekbench Vulkan score of 50,867. Its average benchmark score across recorded tests sits at 46,702. That average places the RX 6550M at the 85th percentile of all GPUs in the database. The Z2 Go GPU, by contrast, has zero recorded benchmark scores and an average score of 0, which places it at the 50th percentile.

Looking at the RX 6550M's nearest rivals provides context for its standing. The Intel Arc A530M averages 46,614, a margin of 0.2% over the RX 6550M. The AMD Radeon RX 5600M averages 46,601, also a 0.2% difference. The NVIDIA RTX A2000 averages 46,043, which is 1.4% behind the RX 6550M. The NVIDIA RTX 5880 Ada Generation averages 45,972, trailing by 1.6%. These four rivals cluster tightly around the RX 6550M, indicating that the 5.816 TFLOPS FP32 figure and the 144.0 GB/s memory bandwidth place it in a competitive mid-range bracket.

Since no head-to-head results exist between the two AMD parts, any direct performance comparison must rely on the individual recorded data for the RX 6550M and the architectural specifications for the Z2 Go GPU. The Z2 Go GPU's lack of benchmark entries means the database cannot yet quantify its real-world performance relative to the RX 6550M.

Architecture Differences

Both GPUs share the same RDNA 2.0 architecture and are fabricated by TSMC on a 6 nm process node. That is where the major similarities end.

The RX 6550M uses the Navi 24 chip, which is a discrete mobile GPU from the Navi Mobile (RX 6000M) generation. It carries 5,400 million transistors on a 107 mm² die, giving a transistor density of 50.5 million transistors per mm². The Z2 Go GPU uses the Rembrandt+ chip, an integrated console-class GPU, and carries 13,100 million transistors on a 208 mm² die, with a transistor density of 63.0 million transistors per mm². The Z2 Go GPU therefore packs more than double the transistor count and nearly double the die area, though it is designed for a much lower power envelope.

The RX 6550M has 1,024 shading units, 64 texture mapping units, 32 ROPs, and 16 ray tracing cores. The Z2 Go GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. The RX 6550M leads in raw compute resources across shading, texturing, and ray tracing, while both parts have the same ROP count.

Clock behavior differs significantly. The RX 6550M has a base clock of 2000 MHz, a game clock of 2560 MHz, and a boost clock of 2840 MHz. The Z2 Go GPU has a base clock of just 800 MHz and a boost clock of 2700 MHz. The RX 6550M's higher base clock is especially notable, as it sustains far more compute throughput at idle-to-mid load. The Z2 Go GPU compensates with a boost clock that reaches within 140 MHz of the RX 6550M's peak, but its compute resources are smaller.

Memory configurations diverge sharply. The RX 6550M uses 4 GB of GDDR6 on a 64-bit bus, with a memory clock of 2250 MHz (18 Gbps effective) and bandwidth of 144.0 GB/s. The Z2 Go GPU uses 16 GB of LPDDR5 on a 128-bit bus, with a memory clock of 800 MHz (6.4 Gbps effective) and bandwidth of 102.4 GB/s. The RX 6550M delivers 41% more memory bandwidth despite the narrower bus, thanks to the much faster GDDR6 memory. The Z2 Go GPU has four times the capacity, which matters for workloads that exceed 4 GB, but its bandwidth is lower.

Compute output follows the shading unit and clock differences. The RX 6550M delivers 5.816 TFLOPS FP32 and 11.63 TFLOPS FP16 (2:1). The Z2 Go GPU delivers 4.147 TFLOPS FP32 and 8.294 TFLOPS FP16 (2:1). The RX 6550M is 40% ahead in FP32 and FP16 throughput. Pixel rates are close: the RX 6550M posts 90.88 GPixel/s versus 86.40 GPixel/s for the Z2 Go GPU. Texture rate favors the RX 6550M at 181.8 GTexel/s versus 129.6 GTexel/s.

Power consumption is a major differentiator. The RX 6550M has a TDP of 80 W and uses no power connectors, fitting an IGP slot width. The Z2 Go GPU has a TDP of 28 W and also uses no power connectors. The Z2 Go GPU draws 35% of the power of the RX 6550M.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 6550M uses a PCIe 4.0 x4 bus interface, while the Z2 Go GPU's bus interface is not recorded. Display outputs differ: the RX 6550M is portable-device dependent, while the Z2 Go GPU has a single USB Type-C output.

Release timing also differs. The RX 6550M launched on 2023-01-03, while the Z2 Go GPU launched on 2024-12-31. The RX 6550M lists Polaris Mobile as its predecessor; the Z2 Go GPU has no predecessor recorded.

Where Each One Wins

The AMD Radeon RX 6550M wins on raw compute throughput in every measured category. Its 5.816 TFLOPS FP32 output is 40% ahead of the Z2 Go GPU's 4.147 TFLOPS. Its shading unit count of 1,024 exceeds the Z2 Go GPU's 768 by one-third. The RX 6550M also leads in texture rate, 181.8 GTexel/s versus 129.6 GTexel/s, and in pixel rate, 90.88 GPixel/s versus 86.40 GPixel/s. Ray tracing resources favor the RX 6550M as well, with 16 ray tracing cores against the Z2 Go GPU's 12.

Memory bandwidth also goes to the RX 6550M. Its GDDR6 memory provides 144.0 GB/s, which is 41% higher than the Z2 Go GPU's 102.4 GB/s LPDDR5. The RX 6550M's higher base clock of 2000 MHz versus 800 MHz means it sustains a much higher floor of performance under continuous load. Its boost clock of 2840 MHz also tops the Z2 Go GPU's 2700 MHz. In the database, the RX 6550M sits at the 85th percentile of all GPUs with an average score of 46,702; the Z2 Go GPU holds the 50th percentile with no recorded score.

The AMD Ryzen Z2 Go GPU wins on power efficiency and memory capacity. Its TDP of 28 W is 35% of the RX 6550M's 80 W, making it suitable for much lower-power designs. The Z2 Go GPU packs 16 GB of LPDDR5, four times the RX 6550M's 4 GB. That capacity advantage allows it to hold larger datasets in memory, which matters for workloads that spill past the RX 6550M's 4 GB limit. The Z2 Go GPU also uses a wider 128-bit memory bus, though the slower LPDDR5 clock means total bandwidth remains lower.

The RX 6550M is the choice for sustained compute throughput, higher frame rates in bandwidth-sensitive workloads, and any task that relies on FP32 or FP16 arithmetic. The Z2 Go GPU is the choice for power-constrained systems that need large memory capacity and modest compute, particularly console-class integrated designs. The 12 ray tracing cores on the Z2 Go GPU still provide DirectX 12 Ultimate support, but the RX 6550M's 16 ray tracing cores and higher clock speeds give it more ray tracing headroom.

The RX 6550M's nearest rivals in the database all sit within 1.6% of its average score, which confirms its position in a tightly contested performance tier. The Z2 Go GPU has no rival data recorded, so its competitive position cannot be assessed beyond its architectural specifications. The two GPUs occupy different design points within the same RDNA 2.0 family: one a discrete mobile part focused on performance, the other an integrated console GPU focused on efficiency and capacity.
