A: The NVIDIA GeForce RTX 2060 SUPER scores 2011, beating the AMD Radeon RX 6600's 1492 by 25.8%. This is the largest single-test margin between the two cards in the head-to-head data.

Q: Which card wins in DirectX 11 performance?

A: The AMD Radeon RX 6600 wins the PassMark DirectX 11 test with a score of 152 versus the RTX 2060 SUPER's 130, a 16.9% advantage. This is the RX 6600's largest winning margin among the benchmark suite.

Q: Is the RTX 2060 SUPER stronger in compute workloads?

A: Yes, narrowly. The NVIDIA card scores 6721 in PassMark GPU Compute, which is 2.5% ahead of the AMD card's 6554. The RTX 2060 SUPER also dominates the Geekbench OpenCL test by 62.5% (76957 vs 28850).

Q: Do both cards support the same modern APIs?

A: Yes, both report DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. However, only the RTX 2060 SUPER includes Tensor Cores (272), while the RX 6600's RT core count is 28 versus the NVIDIA card's 34.

Q: What are the physical size differences between the two cards?

A: The AMD Radeon RX 6600 is shorter at 190 mm (7.5 inches) and slightly taller at 110 mm (4.3 inches) but thicker at 40 mm (1.6 inches). The RTX 2060 SUPER measures 229 mm (9 inches) in length, 113 mm (4.4 inches) in height, and 35 mm (1.4 inches) in width.

Architecture Differences

The two cards come from different manufacturing generations and process nodes. The AMD Radeon RX 6600 uses the Navi 23 chip built on RDNA 2.0 architecture at TSMC's 7 nm process, while the NVIDIA GeForce RTX 2060 SUPER uses the TU106 chip on Turing architecture at TSMC's 12 nm node. This node difference is stark: the RX 6600 packs 11,060 million transistors into a 237 mm² die, yielding a transistor density of 46.7M per mm², whereas the RTX 2060 SUPER crams 10,800 million transistors into a much larger 445 mm² die, for a density of just 24.3M per mm².

The memory subsystems differ significantly in bus width and bandwidth. Both cards have 8 GB of GDDR6 memory, but the RX 6600 uses a 128-bit bus delivering 224.0 GB/s, while the RTX 2060 SUPER employs a 256-bit bus for 448.0 GB/s — exactly double the bandwidth. Memory clock is identical at 1750 MHz (14 Gbps effective).

Core configurations are also markedly different. The RX 6600 has 1792 shading units, 112 TMUs, and 64 ROPs, with 28 ray tracing cores. The RTX 2060 SUPER has more of everything: 2176 shading units, 136 TMUs, 64 ROPs, and 34 RT cores, plus 272 Tensor Cores that the AMD card lacks entirely. This explains the NVIDIA card's higher theoretical pixel rate of 105.6 GPixel/s and texture rate of 224.4 GTexel/s, though the AMD card actually posts higher rates: 159.4 GPixel/s and 279.0 GTexel/s respectively, driven by its much higher boost clock.

Clock speeds favor AMD decisively. The RX 6600 runs at a 1626 MHz base and 2491 MHz boost, with a 2044 MHz game clock, versus the RTX 2060 SUPER's 1470 MHz base and 1650 MHz boost. This clock advantage helps the RX 6600 reach 8.928 TFLOPS of FP32 performance, while the RTX 2060 SUPER manages 7.181 TFLOPS.

Power requirements also diverge. The RX 6600 has a 132 W TDP with a 300 W suggested PSU, while the RTX 2060 SUPER draws 175 W and requires a 450 W PSU. Both are dual-slot cards with a single 8-pin power connector, but the AMD card uses PCIe 4.0 x8, whereas the NVIDIA card uses PCIe 3.0 x16.

Where Each One Wins

The AMD Radeon RX 6600 is the pick for legacy API workloads. Its 16.9% win in PassMark DirectX 11 and 4.1% win in PassMark G2D (889 vs 854) show strength in older or lighter rendering paths. The RX 6600 also claims the higher average benchmark score (19036 vs 18093), suggesting it edges out the RTX 2060 SUPER in overall mixed-workload balance.

The NVIDIA GeForce RTX 2060 SUPER dominates modern and compute-heavy scenarios. It wins 3DMark Steel Nomad DX12 by 25.8%, Geekbench OpenCL by 62.5%, and Geekbench Vulkan by 12.6%. Its PassMark G3D score of 16462 beats the RX 6600's 15096 by 8.3%, and it also wins DirectX 9 (218 vs 197), DirectX 10 (111 vs 95), and DirectX 12 (61 vs 51) tests. The GPU Compute margin is slim but real: 6721 vs 6554, a 2.5% NVIDIA lead.

For ray tracing, the RTX 2060 SUPER's 34 RT cores versus the RX 6600's 28, combined with Tensor Cores for AI acceleration, give it a structural advantage in this area, though no dedicated RT benchmark is present in the data.

Head-to-Head Benchmarks

The biggest NVIDIA win is in Geekbench OpenCL, where the RTX 2060 SUPER scores 76957 against the RX 6600's 28850 — a massive 62.5% gap. This is the single largest delta in the entire dataset and suggests the NVIDIA card has a substantial advantage in compute-heavy OpenCL applications. The second-largest margin is the 3DMark Steel Nomad DX12 test: 2011 vs 1492, a 25.8% NVIDIA lead that indicates better performance in modern DX12 workloads.

The RTX 2060 SUPER also wins Geekbench Vulkan by 12.6% (77402 vs 67623), PassMark DirectX 12 by 16.4% (61 vs 51), DirectX 10 by 14.4% (111 vs 95), and DirectX 9 by 9.6% (218 vs 197). Its PassMark G3D score of 16462 beats the RX 6600's 15096 by 8.3%, and the GPU Compute lead is 2.5% (6721 vs 6554).

The AMD RX 6600's wins are fewer but notable. In PassMark DirectX 11, it scores 152 versus 130, a 16.9% advantage. In PassMark G2D, it wins 889 to 854, a 4.1% margin. These wins suggest the RX 6600 has an edge in older DirectX 11 titles and 2D rendering tasks, potentially benefiting from its higher clock speeds.

The Verdict

The data clearly favors the NVIDIA GeForce RTX 2060 SUPER for users prioritizing modern, compute-heavy, or DX12 workloads. Its 25.8% lead in 3DMark Steel Nomad DX12 and 62.5% lead in Geekbench OpenCL are the standout performance deltas, and it wins 8 of the 10 head-to-head benchmarks. The RTX 2060 SUPER also offers double the memory bandwidth (448.0 GB/s vs 224.0 GB/s) and Tensor Cores, making it the more capable card for ray tracing and AI-accelerated tasks.

The AMD Radeon RX 6600 appeals to a different profile. It has the higher average benchmark score (19036 vs 18093) and wins in DirectX 11 and 2D performance. Its lower TDP (132 W vs 175 W) and smaller physical footprint make it the more efficient and compact option, and its higher boost clock (2491 MHz vs 1650 MHz) delivers strong rasterization in legacy APIs. Users focused on DirectX 11 gaming or constrained by power and space should favor the RX 6600.

For everything else — DX12, compute, Vulkan, and overall benchmark wins — the RTX 2060 SUPER is the data-backed choice. The verdict is not close on modern workloads: the NVIDIA card leads by double digits in the most demanding tests, and its 63rd percentile rival list includes the RTX 4050 Mobile and RTX 2000 Ada Generation, while the RTX 2060 SUPER's nearest rivals include the RTX 3060 Mobile and Radeon Pro 5700.
