AMD Radeon RX 6600M vs NVIDIA GeForce RTX 5060 Mobile Comparison

The benchmark data for the AMD Radeon RX 6600M and the NVIDIA GeForce RTX 5060 Mobile presents a clear hierarchy, with the NVIDIA part securing a decisive victory across every single test in the head-to-head comparison. The AMD Radeon RX 6600M, an end-of-life product from the Radeon RX 6000 series, is positioned against a current-generation GeForce RTX 50-series part that is still in active production. The data indicates a significant generational performance gap, and the following analysis details the specific margins of victory, architectural underpinnings, and resulting use-case scenarios for each mobile GPU.

Head-to-Head Benchmarks

The most substantial performance disparity appears in the modern DirectX 12 and compute-oriented workloads. In the 3DMark Steel Nomad DX12 test, the NVIDIA GeForce RTX 5060 Mobile scores 3013.5, which is a 50.4% improvement over the AMD Radeon RX 6600M’s score of 1495. This indicates that the RTX 5060 Mobile is vastly better equipped for the latest gaming APIs, effectively doubling the performance of the older AMD part in this specific stress test.

A similar, though less extreme, trend is visible in the PassMark DirectX 12 benchmark, where the RTX 5060 Mobile's score of 87 is 40.2% higher than the RX 6600M's 52. This consistency across different benchmarking suites suggests that the NVIDIA architecture provides a substantial advantage in low-level, multi-threaded graphics workloads. In the older DirectX 10 and DirectX 11 APIs, the lead narrows but remains firmly in NVIDIA's favor. The RTX 5060 Mobile scores 119 in the DirectX 10 test (26.9% ahead) and 168 in the DirectX 11 test (19% ahead of the RX 6600M's 136). These results show that while the gap is smaller in legacy APIs, the GeForce part still holds a commanding lead.

Compute performance, as measured by the PassMark GPU Compute test, shows the RTX 5060 Mobile achieving 7607, a 25.8% advantage over the RX 6600M's 5646. This is a notable margin for tasks that leverage general-purpose GPU processing. The Geekbench results corroborate this strength, with the NVIDIA GPU scoring 96969 in OpenCL (30.1% ahead) and 96451 in Vulkan (23.5% ahead of the AMD's 73740). These numbers point to the RTX 5060 Mobile being the superior choice for any application that offloads parallel processing to the GPU.

Even in the synthetic 2D test, the RTX 5060 Mobile leads. The PassMark G2D score of 876 is 16.9% higher than the 728 achieved by the RX 6600M. The narrowest margin of victory for the NVIDIA GPU is in the PassMark DirectX 9 test, where it scores 203 versus the AMD's 184, a 9.4% difference. In the overall PassMark G3D score, the RTX 5060 Mobile’s 18852 is 26.1% ahead of the RX 6600M's 13929. With a perfect 10 wins out of 10 head-to-head benchmarks, the data is unequivocal: the RTX 5060 Mobile is the faster GPU in every measured category.

The Verdict

The data points to a single, clear conclusion: the NVIDIA GeForce RTX 5060 Mobile is the superior performer for nearly all use cases. It wins every benchmark in the comparison, often by significant margins. For users prioritizing raw gaming performance, particularly in modern DirectX 12 titles, the RTX 5060 Mobile is the definitive choice, as its 50.4% lead in Steel Nomad demonstrates. Its advantages in OpenCL and Vulkan also make it the better option for creative professionals or anyone relying on GPU-accelerated compute.

The AMD Radeon RX 6600M, despite its age, is not without merit. Its average benchmark score of 23273 is actually slightly higher than the RTX 5060 Mobile's average of 22435, a quirk of the averaging methodology that includes different benchmark suites. However, this is a statistical anomaly that does not reflect the head-to-head results, where the NVIDIA GPU wins decisively. The Radeon's nearest rivals, such as the AMD Radeon R9 M290X and the NVIDIA P106-100, are all several generations old, indicating that its performance class is now in the entry-level or legacy segment.

Therefore, the recommendation from the data is straightforward. The RTX 5060 Mobile is the pick for anyone who wants the best available performance in gaming and compute tasks. The RX 6600M, while a capable performer in its own right, is outclassed by the newer NVIDIA part. The data suggests that the RTX 5060 Mobile is not just a refresh, but a substantial step up in performance, making it the logical choice for a new system. The AMD part should only be considered if the system is already in hand and the user is not prioritizing the performance levels demonstrated by the GeForce GPU.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The AMD Radeon RX 6600M utilizes the RDNA 2.0 architecture on a 7 nm process from TSMC, with a die size of 237 mm² housing 11,060 million transistors. In contrast, the NVIDIA GeForce RTX 5060 Mobile is based on the newer Blackwell 2.0 architecture, manufactured on a 5 nm process, also by TSMC. This results in a smaller die of 181 mm² but a much higher transistor count of 21,900 million, leading to a significantly higher transistor density of 121.0M per mm² versus the AMD's 46.7M per mm².

These architectural differences lead to distinct processing capabilities. The NVIDIA GPU has a much higher number of shading units, with 3328 compared to the AMD's 1792. However, the AMD part has a higher number of texture mapping units (112 vs. 104) and render output units (64 vs. 48). In terms of ray tracing, the RTX 5060 Mobile has 26 RT cores, while the RX 6600M has 28, but the NVIDIA GPU is the only one of the two with 104 tensor cores, which are essential for AI-accelerated features like DLSS. The AMD GPU's FP32 performance is rated at 8.659 TFLOPS, while the NVIDIA GPU is higher at 9.684 TFLOPS. The AMD part does have a higher FP16 rating of 17.32 TFLOPS (2:1 ratio) versus the NVIDIA's 9.684 TFLOPS (1:1 ratio), but this advantage is not reflected in the benchmark results.

Memory architecture also differs significantly. Both GPUs have 8 GB of memory on a 128-bit bus, but the AMD RX 6600M uses GDDR6 at 14 Gbps effective, yielding a bandwidth of 224.0 GB/s. The NVIDIA RTX 5060 Mobile uses faster GDDR7 memory at 24 Gbps effective, which provides a substantial bandwidth advantage of 384.0 GB/s. This 71.4% increase in memory bandwidth is likely a major contributor to the NVIDIA GPU's superior performance in high-resolution and texture-heavy workloads. The power characteristics also diverge, with the AMD GPU having a TDP of 100 W and the NVIDIA GPU a much lower TDP of 45 W, a significant efficiency improvement for the newer part.

The AMD Radeon RX 6600M does not win a single benchmark in the provided data. Its narrowest deficit is in the PassMark DirectX 9 test, where it trails the RTX 5060 Mobile by only 9.4%. This suggests that for very old games or applications using legacy APIs, the performance gap is less pronounced, though the NVIDIA GPU still holds the advantage. The RX 6600M's only statistical point of parity with its rival is its higher overall average benchmark score of 23273 versus the RTX 5060 Mobile's 22435, but this is due to the inclusion of different tests in the average and does not reflect a performance win in any direct comparison. Based on the data, the RTX 5060 Mobile is the definitive choice for all performance-critical tasks.
