AMD Radeon Pro W6600M vs Intel Arc A550M Comparison

AMD Radeon Pro W6600M vs Intel Arc A550M: the database shows a clear overall winner, but the two mobile GPUs serve different priorities. The AMD part wins both recorded benchmark tests, with its largest margin coming in Vulkan workloads. The Intel part, despite a higher raw FP32 ceiling, trails in the actual measured OpenCL and Vulkan scores. This makes the W6600M the safer choice for cross-API compatibility and peak performance, while the A550M offers a lower power envelope that can matter in thin-and-light designs.

Where Each One Wins

The AMD Radeon Pro W6600M wins every recorded head-to-head benchmark in the database. In Geekbench OpenCL, it scores 56,140 against the Intel Arc A550M's 49,894, a 12.5% advantage. The gap widens dramatically in Geekbench Vulkan, where the AMD card posts 67,652 versus 49,580, a 36.5% lead. For any workload that leverages Vulkan, whether that is modern game engines or compute APIs, the W6600M is the decisive pick.

The Intel Arc A550M, by contrast, does not win a single recorded test in this comparison. However, its value lies elsewhere. The A550M carries a 60 W TDP, which is one-third lower than the W6600M's 90 W. In a mobile context, that power difference can translate into thinner chassis, quieter cooling, or longer battery life under sustained load. The data also shows the A550M has a higher texture rate (262.4 GTexel/s vs 227.8 GTexel/s) and more shading units (2048 vs 1792), which suggests it may handle certain fill-rate-bound or shader-heavy tasks better in theory, though the benchmark results do not confirm that in practice.

For users who prioritize raw compute and graphics API performance, the AMD Radeon Pro W6600M is the unambiguous winner. For users who need a lower-power mobile GPU that still delivers respectable performance, the Intel Arc A550M is the more efficient option, even if it loses every measured test here.

Head-to-Head Benchmarks

The two recorded benchmark tests tell a consistent story. In Geekbench OpenCL, the AMD Radeon Pro W6600M scores 56,140 against the Intel Arc A550M's 49,894. That 12.5% lead is substantial but not overwhelming. OpenCL is a general-purpose compute API, and the AMD architecture appears to extract more real-world performance from its 7.290 TFLOPS FP32 throughput than the Intel part does from its higher 8.397 TFLOPS figure.

The Vulkan result is where the separation becomes stark. The W6600M posts 67,652, while the A550M manages only 49,580. The 36.5% delta is more than three times the OpenCL gap. This suggests the RDNA 2.0 architecture in the AMD chip has a significant driver or hardware efficiency advantage in Vulkan workloads. For users running Vulkan-based games or compute applications, the W6600M is not just faster, it is in a different performance class.

The average benchmark score reinforces this. The W6600M averages 61,896, which places it in the 89th percentile of all GPUs in the database. The A550M averages 49,737, good for the 86th percentile. While both are above the median, the W6600M's percentile ranking is meaningfully higher, reflecting its stronger overall position relative to the entire GPU landscape.

Looking at the nearest rivals for each card provides additional context. The W6600M is nearly identical to the AMD Radeon 8050S (62,108, a 0.3% deficit) and slightly ahead of the NVIDIA GeForce RTX 4090 (60,347) and Intel Arc Pro A60 (60,326), both by 2.6%. This means the W6600M competes with some very high-end desktop parts, despite being a mobile IGP. The A550M, on the other hand, sits in a tighter cluster, within 2.6% of the AMD Radeon RX 6800 XT (48,477) and just behind the RTX 5070 Ti and RX Vega 64. The A550M's performance neighborhood is more crowded, and it does not have a clear edge over any of its nearest rivals.

Specification Differences

The two GPUs differ in several key specifications. The AMD Radeon Pro W6600M uses a Navi 23 chip built on RDNA 2.0 architecture at TSMC's 7 nm process. The Intel Arc A550M uses a DG2-512 chip on Xe-HPG architecture at TSMC's 6 nm process. The process node difference is small, but the transistor counts are not: the Intel chip packs 21,700 million transistors on a 406 mm² die, while the AMD chip has 11,060 million on 237 mm². This gives the Intel part a higher transistor density at 53.4M per mm² versus 46.7M per mm².

Clock speeds also diverge. The AMD part has a base clock of 1224 MHz and a boost of 2034 MHz. The Intel part has a much lower base of 900 MHz but a slightly higher boost of 2050 MHz. The memory clocks are identical at 1750 MHz with 14 Gbps effective speed.

The compute unit counts favor Intel in raw numbers. The A550M has 2048 shading units, 128 TMUs, and 64 ROPs. The W6600M has 1792 shading units, 112 TMUs, and 64 ROPs. This translates to a higher texture rate for Intel (262.4 GTexel/s vs 227.8 GTexel/s) and a nearly identical pixel rate (131.2 GPixel/s vs 130.2 GPixel/s). The FP32 throughput also favors Intel at 8.397 TFLOPS versus 7.290 TFLOPS, and FP16 follows the same pattern at 16.79 TFLOPS versus 14.58 TFLOPS.

Power consumption is a major differentiator. The Intel Arc A550M has a 60 W TDP, while the AMD Radeon Pro W6600M draws 90 W. This 30 W difference is significant for mobile designs. Both are listed as IGP slot width with no external power connectors, and both use PCIe 4.0 x16. Display outputs are portable device dependent for both.

Architecture Differences

The architectural split is fundamental. AMD's RDNA 2.0 is a mature, gaming-focused design that emphasizes ray tracing and compute efficiency. The W6600M includes 28 ray tracing cores, which is a high count for a mobile GPU. Intel's Xe-HPG architecture, found in the Alchemist generation, is Intel's first serious attempt at discrete-class mobile graphics. It includes just 16 ray tracing cores, a notable deficit.

The transistor budgets tell a story of different design philosophies. Intel's DG2-512 die is nearly twice the size of AMD's Navi 23 at 406 mm² versus 237 mm², with nearly double the transistors. Despite this, the AMD part wins the recorded benchmarks. This points to a significant efficiency advantage in RDNA 2.0's execution, at least in the tested workloads. The Intel part's higher theoretical FP32 and texture rates do not translate into better Geekbench scores, which suggests driver maturity or scheduling inefficiencies in the Xe-HPG architecture.

Both GPUs support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. There is no difference in API support. The production status for both is end-of-life, and neither has a recorded launch MSRP in the database. The AMD part has a release date of June 7, 2021, while the Intel part has no recorded release date. The AMD part's predecessor is FirePro Mobile, while the Intel part has no predecessor listed.

The power envelope difference is the most practical architectural consequence. The 60 W A550M draws 33% less power than the 90 W W6600M. In a laptop, that can mean a smaller cooling solution or a larger battery budget. However, the benchmark data shows that power savings come at a significant performance cost, especially in Vulkan. The choice between these two is effectively a choice between peak performance and power efficiency.
