Architecture Differences

The architectural divide between these two mobile GPUs is substantial. The AMD Radeon RX 7600M is built on the RDNA 3.0 architecture, part of the Radeon RX 7000 series, and uses the Navi 33 chip with the codename "Hotpink Bonefish." In contrast, the AMD Radeon RX 6550M employs the older RDNA 2.0 architecture from the Radeon RX 6000 series, built on the Navi 24 chip.

Both GPUs are manufactured by TSMC on a 6 nm process node, but their transistor budgets differ dramatically. The RX 7600M integrates 13,300 million transistors on a 204 mm² die, resulting in a transistor density of 65.2M per mm². The RX 6550M is a much smaller chip, with 5,400 million transistors on a 107 mm² die, giving a density of 50.5M per mm². This represents roughly 2.5 times more transistors on the RX 7600M.

The core configurational differences are equally stark. The RX 7600M has 1,792 shading units, 112 texture mapping units, and 64 render output units. It also includes 28 ray tracing cores. The RX 6550M comes with 1,024 shading units, 64 TMUs, and 32 ROPs, along with 16 ray tracing cores. This gives the RX 7600M a 75% advantage in shader count, 75% more TMUs, and double the ROPs.

The memory subsystems also reflect their different positions. The RX 7600M uses a 128-bit bus with 8 GB of GDDR6 memory, while the RX 6550M uses a 64-bit bus with 4 GB. The RX 7600M's effective memory speed is rated at 16 Gbps, whereas the RX 6550M's memory runs at 18 Gbps effective. Despite the higher memory clock on the RX 6550M, the wider bus on the RX 7600M gives it significantly more bandwidth.

The bus interface also differs: the RX 7600M connects via PCIe 4.0 x16, while the RX 6550M uses PCIe 4.0 x4. The RX 7600M has a slightly higher TDP at 90 W compared to 80 W for the RX 6550M, though both are integrated into mobile devices with no external power connectors and are classified as IGP slot width.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical. Neither has tensor cores, and both are listed as Active in production status with the same release date of January 3, 2023. Their predecessor is Polaris Mobile for both, and neither has a listed successor.

Head-to-Head Benchmarks

The database contains a direct comparison between these two GPUs using the Geekbench OpenCL test. In this benchmark, the AMD Radeon RX 7600M scores 63,775, while the AMD Radeon RX 6550M scores 42,536. The RX 7600M wins this head-to-head with a delta of 49.9%, meaning it is nearly 50% faster in this compute workload.

Examining the nearest rivals for each GPU puts this performance gap in context. The RX 7600M sits just 0.1% below the AMD Radeon RX 9060 XT LP (which scores 63,830) and the NVIDIA CMP 30HX (63,842). It is 0.1% above the AMD Radeon Pro Vega 56 (63,693) and 0.7% below the AMD Radeon Pro WX 9100 (64,212). This places the RX 7600M in a tight performance cluster among desktop-class cards, which is notable for a mobile GPU.

The RX 6550M, by contrast, sits among a different set of rivals. It is 0.2% above the Intel Arc A530M (46,614) and the AMD Radeon RX 5600M (46,601). It leads the NVIDIA RTX A2000 (46,043) by 1.4% and the NVIDIA RTX 5880 Ada Generation (45,972) by 1.6%. The gap between the two AMD mobile GPUs is far larger than the differences within their respective rival clusters.

The RX 7600M's raw compute advantage is clear from the FP32 throughput figures: 17.27 TFLOPS versus 5.816 TFLOPS for the RX 6550M. This is a 197% difference in theoretical peak performance. The pixel rate of the RX 7600M is 154.2 GPixel/s, compared to 90.88 GPixel/s for the RX 6550M, and the texture rate is 269.9 GTexel/s versus 181.8 GTexel/s.

The RX 7600M also has a distinct advantage in ray tracing resources with 28 RT cores versus 16 on the RX 6550M, though no dedicated ray tracing benchmark scores are recorded in the database for either GPU. The OpenCL score remains the only direct head-to-head measurement, and it decisively favors the RX 7600M.

Where Each One Wins

The AMD Radeon RX 7600M is the clear winner in overall compute performance. Its OpenCL score of 63,775 is 49.9% higher than the RX 6550M's 42,536, and it wins the only recorded head-to-head benchmark. The RX 7600M also dominates in memory bandwidth with 256.0 GB/s versus 144.0 GB/s, which benefits memory-intensive workloads such as high-resolution texture streaming and large data sets. Its 8 GB VRAM capacity is double that of the RX 6550M, making it better suited for modern games and applications with higher VRAM requirements.

The RX 7600M's larger shader count (1,792 versus 1,024) and higher FP32 throughput (17.27 TFLOPS versus 5.816 TFLOPS) give it a substantial edge in general-purpose compute and traditional rasterization workloads. Its 28 RT cores versus 16 also suggest better ray tracing performance, though no direct RT benchmark is recorded. The RX 7600M's 89th percentile ranking versus the RX 6550M's 85th percentile reinforces its higher standing in the overall GPU hierarchy.

The AMD Radeon RX 6550M does have its own advantages, though they are narrower in scope. It has a higher base clock (2000 MHz versus 1500 MHz) and a higher boost clock (2840 MHz versus 2410 MHz), as well as a higher game clock (2560 MHz versus 2070 MHz). Its memory runs at a higher effective speed (18 Gbps versus 16 Gbps), and its memory clock of 2250 MHz exceeds the RX 7600M's 2000 MHz. The RX 6550M also has a lower TDP at 80 W versus 90 W, which could translate to lower power consumption in constrained mobile chassis.

In terms of competitive positioning, the RX 7600M sits alongside higher-end desktop and workstation GPUs like the AMD Radeon Pro Vega 56 and the AMD Radeon Pro WX 9100, while the RX 6550M competes with mid-range options like the Intel Arc A530M and the AMD Radeon RX 5600M. The RX 6550M's higher clock speeds may give it an edge in lightly threaded or latency-sensitive workloads, but the RX 7600M's overwhelming resource advantage makes it the superior choice for demanding applications.

For users prioritizing compute performance, memory capacity, and bandwidth, the RX 7600M is the unequivocal pick. For those needing lower power draw and higher clock speeds in a smaller package, the RX 6550M offers a more modest but still viable option. The database shows one clear win for the RX 7600M and none for the RX 6550M in direct comparison.
