AMD Radeon RX 6600M vs NVIDIA GeForce RTX 5060 Comparison

The Verdict

The benchmark data separates these two GPUs cleanly. The NVIDIA GeForce RTX 5060 wins all 10 recorded head-to-head tests, with an average benchmark score of 26331 against 23273 for the AMD Radeon RX 6600M. That is a 13% overall advantage for the NVIDIA part, and the individual test deltas range from a modest 22.3% in DirectX 9 to a decisive 142.7% in 3DMark Steel Nomad. The RTX 5060 also sits at the 72nd percentile among all GPUs, while the RX 6600M sits at the 68th. For a desktop gamer building a new system, the RTX 5060 is the clear pick from a pure performance standpoint. The RX 6600M, however, is an end-of-life mobile part with a 100 W TDP, no power connectors, and portable-device-dependent outputs. It belongs in a laptop or a compact system where its lower power draw and integrated form factor matter more than raw frame rates. If you are upgrading a desktop, there is no contest in the data. If you are choosing a mobile GPU, the RX 6600M remains a capable option but the RTX 5060's benchmark lead suggests it will age better.

Where Each One Wins

The RTX 5060 wins every recorded benchmark, so the use-case split is not about which GPU wins specific tests. It is about which GPU fits the physical and power constraints of the build. The RTX 5060 is a dual-slot, 145 W card requiring a 300 W power supply and a single 8-pin connector. It is 241 mm long, 111 mm tall, and 40 mm wide. That makes it a standard desktop card for a mid-tower or larger chassis. The RX 6600M, by contrast, is an IGP (integrated GPU) class part with no power connectors, a 100 W TDP, and no listed dimensions. It is designed for portable devices where the system board provides power and cooling. So the practical split is: the RTX 5060 wins for desktop gaming, ray tracing, and high-resolution workloads. The RX 6600M wins for thin-and-light laptops or mini PCs where the 100 W TDP and lack of external power connectors are advantages. In every pure performance metric, the RTX 5060 is ahead, but the RX 6600M occupies a niche the RTX 5060 cannot physically fill.

Architecture Differences

The two GPUs come from different generations and design philosophies. The RTX 5060 uses the GB206 chip on a 5 nm TSMC process, with 21,900 million transistors on a 181 mm² die. That works out to a transistor density of 121.0M per mm². The RX 6600M uses the Navi 23 chip on a 7 nm TSMC process, with 11,060 million transistors on a 237 mm² die, for a density of 46.7M per mm². The RTX 5060 packs nearly twice the transistors into a smaller die, which explains its higher compute throughput. The architecture is Blackwell 2.0 for NVIDIA versus RDNA 2.0 for AMD. The RTX 5060 has 3840 shading units, 120 texture mapping units, 48 ROPs, 30 ray tracing cores, and 120 tensor cores. The RX 6600M has 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores, with no tensor cores listed. The RTX 5060's FP32 throughput is 19.18 TFLOPS, more than double the RX 6600M's 8.659 TFLOPS. The RX 6600M does have a higher FP16 rate at 17.32 TFLOPS via a 2:1 ratio, while the RTX 5060 matches FP16 to FP32 at 19.18 TFLOPS. Memory also differs: the RTX 5060 uses 8 GB of GDDR7 on a 128-bit bus with 448.0 GB/s bandwidth, while the RX 6600M uses 8 GB of GDDR6 on the same 128-bit bus but with only 224.0 GB/s bandwidth. The RTX 5060 runs on PCIe 5.0 x8, the RX 6600M on PCIe 4.0 x8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5060 has a 145 W TDP versus 100 W for the RX 6600M, reflecting the performance gap.

Head-to-Head Benchmarks

The largest win for the RTX 5060 comes in 3DMark Steel Nomad DX12, where it scores 3628 against 1495 for the RX 6600M. That is a 142.7% delta, meaning the RTX 5060 delivers more than 2.4 times the performance in this modern DirectX 12 test. This is the most important number in the comparison because it represents a current-generation workload. The second-largest gap is in PassMark GPU Compute, where the RTX 5060 scores 10899 versus 5646, a 93% delta. This shows the RTX 5060's advantage extends beyond graphics into general-purpose compute, likely driven by its tensor cores and higher FP32 throughput. In Geekbench OpenCL, the RTX 5060 scores 112787 versus 67765, a 66.4% delta, and in Geekbench Vulkan it scores 113321 versus 73740, a 53.7% delta. These two tests confirm the RTX 5060 leads across different compute APIs. In PassMark G2D, the RTX 5060 scores 1154 versus 728, a 58.5% delta, indicating faster 2D operations. PassMark G3D shows 20891 versus 13929, a 50% delta. The legacy DirectX tests show smaller but still consistent wins: DirectX 10 gives 127 versus 87 (46% delta), DirectX 11 gives 200 versus 136 (47.1% delta), DirectX 12 gives 77 versus 52 (48.1% delta), and DirectX 9 gives 225 versus 184 (22.3% delta). The DirectX 9 result is the smallest gap, suggesting the RX 6600M is relatively less disadvantaged in older API workloads, but it still loses.
