AMD Radeon RX 6600M vs NVIDIA GeForce RTX 2070 SUPER Comparison

AMD Radeon RX 6600M vs NVIDIA GeForce RTX 2070 SUPER

The benchmark database places the AMD Radeon RX 6600M at the 68th percentile of all GPUs, while the NVIDIA GeForce RTX 2070 SUPER sits at the 65th percentile. However, the direct head-to-head measurements tell a different story, with the RTX 2070 SUPER winning all ten recorded tests. The RX 6600M's higher percentile is a reflection of its average benchmark score across a wider set of tests, not its performance against this specific NVIDIA rival. The data shows a consistent performance gap favoring the older, larger desktop-class NVIDIA card, despite the AMD part being a newer mobile-focused design.

Where Each One Wins

The Radeon RX 6600M does not win a single recorded head-to-head benchmark against the RTX 2070 SUPER. In the ten tests where both GPUs have scores, the NVIDIA card takes every victory. This is not a close contest with mixed results; it is a clean sweep. The RX 6600M's strengths, as reflected in the database, lie elsewhere: its average benchmark score of 23,273 versus the RTX 2070 SUPER's 20,282, and its higher percentile ranking of 68 versus 65. These aggregate figures suggest the AMD card performs better across the entire GPU landscape, likely due to its efficiency in a broader range of lighter workloads or its mobile-oriented design advantages.

For specific use cases, the RTX 2070 SUPER wins decisively. In DirectX 12 workloads, measured by 3DMark Steel Nomad, the NVIDIA card scores 1,651 against 1,495, a 9.4% advantage. For compute-heavy tasks, the gap widens: PassMark GPU Compute shows a 25.3% lead for NVIDIA (7,557 vs 5,646). The largest single margin is in PassMark DirectX 10, where the RTX 2070 SUPER is 34.1% ahead (132 vs 87). The AMD card's best showing relative to its rival is in PassMark DirectX 11, where it trails by only 9.9%. The RX 6600M wins no categories outright, so its "win" is purely statistical: a higher overall percentile and average score against the full GPU population, not against this particular competitor.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The AMD Radeon RX 6600M uses the Navi 23 chip built on RDNA 2.0 architecture, fabricated on TSMC's 7 nm process. It packs 11,060 million transistors into a 237 mm² die, yielding a transistor density of 46.7 million per square millimeter. The NVIDIA GeForce RTX 2070 SUPER uses the TU104 chip with Turing architecture, also from TSMC but on a larger 12 nm process. Its die is 545 mm² and contains 13,600 million transistors, resulting in a much lower density of 25.0 million per square millimeter. This means the AMD chip is physically smaller yet denser, while the NVIDIA chip is larger with more raw transistor count.

The NVIDIA card has more of nearly every compute unit: 2,560 shading units versus 1,792, 160 texture mapping units versus 112, and 40 ray tracing cores versus 28. The RTX 2070 SUPER also includes 320 tensor cores, which the RX 6600M lacks entirely. Both have 64 raster output units. Clock speeds favor AMD: the RX 6600M has a base clock of 2,068 MHz and a boost clock of 2,416 MHz, while the RTX 2070 SUPER runs at 1,605 MHz base and 1,770 MHz boost. Despite the higher clocks, AMD's lower unit counts result in a slightly lower FP32 throughput: 8.659 TFLOPS versus NVIDIA's 9.062 TFLOPS. Texture and pixel rates tell a similar story: the RTX 2070 SUPER achieves 283.2 GTexel/s against 270.6 GTexel/s, but the RX 6600M has a higher pixel rate at 154.6 GPixel/s versus 113.3 GPixel/s, a result of its higher clocks with equal ROPs.

Memory configurations differ substantially. Both use 8 GB of GDDR6, but the RTX 2070 SUPER has a 256-bit bus and 448.0 GB/s bandwidth, while the RX 6600M uses a 128-bit bus and 224.0 GB/s. Both run memory at 1750 MHz with 14 Gbps effective speed. The NVIDIA card also carries more features in other areas: it has dual-slot cooling, a 215 W TDP, and requires both a 6-pin and 8-pin power connector, plus a 550 W suggested PSU. The RX 6600M is an integrated graphics package (IGP) with a 100 W TDP and no external power connectors. Bus interfaces differ too: PCIe 4.0 x8 for AMD versus PCIe 3.0 x16 for NVIDIA. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The largest victory for the RTX 2070 SUPER comes in PassMark DirectX 10, where it scores 132 against the RX 6600M's 87, a 34.1% gap. This is the only test where the margin exceeds 30%. The next biggest margins are in compute and general 3D workloads. PassMark GPU Compute shows 7,557 versus 5,646, a 25.3% lead. PassMark G3D, a broader 3D performance metric, gives the NVIDIA card 18,169 versus 13,929, a 23.3% advantage. PassMark DirectX 12 follows with 67 versus 52, a 22.4% gap. These four tests establish the RTX 2070 SUPER as clearly ahead in sustained, heavy workloads.

The Geekbench results show a consistent but slightly smaller NVIDIA edge. In Geekbench OpenCL, the RTX 2070 SUPER scores 83,358 against 67,765, an 18.7% difference. Geekbench Vulkan yields 90,637 versus 73,740, an 18.6% gap. PassMark DirectX 9 shows a 17.5% lead (223 vs 184), and PassMark G2D, a 2D graphics test, has the NVIDIA card at 878 versus 728, a 17.1% margin. The closest contest is PassMark DirectX 11, where the RTX 2070 SUPER wins 151 to 136, a 9.9% advantage. In 3DMark Steel Nomad, the gap is 9.4% (1,651 vs 1,495), the second-smallest margin. Across all ten tests, the delta ranges from 9.4% to 34.1%, with no test where the RX 6600M comes within single digits of winning.
