AMD Radeon RX 6600 LE vs NVIDIA GeForce RTX 4060 AD106 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the NVIDIA GeForce RTX 4060 AD106 has no benchmark scores listed in the database, while the AMD Radeon RX 6600 LE has two recorded results. The AMD card achieves an average benchmark score of 70,829, which places it in the 91st percentile of all GPUs tracked. The RTX 4060 AD106, by contrast, has an average benchmark score of 0 and sits at the 50th percentile, indicating that no direct head-to-head measurements exist in the current dataset.

The RX 6600 LE's OpenCL score is 69,229, while its Vulkan score is 72,428. These two results bracket the card's average, with Vulkan showing a 4.6% advantage over OpenCL in the card's own results. The nearest rivals in the database provide context for the RX 6600 LE's standing. The AMD Radeon RX 6650M leads the RX 6600 LE by 1.3%, with an average score of 71,768. The NVIDIA RTX A3000 Mobile trails the RX 6600 LE by 1%, scoring 70,140. The NVIDIA Quadro P6000 is 1.2% behind at 69,986, and the AMD Radeon Pro WX 8200 is 1.4% behind at 69,870.

Because the RTX 4060 AD106 lacks any recorded benchmarks, the database cannot show which card wins in any specific compute test. The absence of scores for the NVIDIA card means the win count stands at zero for both sides in the head-to-head section. The data reveals a clear disparity: one card has substantial measurement history, the other has none. This makes any performance comparison impossible from the recorded metrics alone. The RTX 4060 AD106's 50th percentile ranking and zero average score suggest the database has not yet captured results for this part, possibly due to its end-of-life production status or a gap in data collection.

Architecture Differences

The two GPUs come from different architectural generations and use different manufacturing processes. The AMD Radeon RX 6600 LE uses the Navi 23 chip built on RDNA 2.0 architecture, fabricated on TSMC's 7 nm process. The NVIDIA GeForce RTX 4060 AD106 uses the AD106 chip with Ada Lovelace architecture, fabricated on TSMC's 5 nm process. The process node difference is significant: 7 nm versus 5 nm, which affects transistor density and efficiency.

Transistor counts differ substantially. The RX 6600 LE contains 11,060 million transistors on a die size of 237 mm², yielding a transistor density of 46.7 million transistors per square millimeter. The RTX 4060 AD106 contains 22,900 million transistors on a smaller die of 188 mm², achieving a density of 121.8 million transistors per square millimeter. The NVIDIA chip packs more than twice the transistors into a smaller area, a direct consequence of the denser 5 nm process.

Shader and compute resources diverge sharply. The RX 6600 LE has 1,792 shading units, 112 texture mapping units, and 64 raster output units. The RTX 4060 AD106 has 3,072 shading units, 96 TMUs, and 48 ROPs. The NVIDIA card has 71% more shading units but 14% fewer TMUs and 25% fewer ROPs. Ray tracing cores also differ: the AMD card has 28 RT cores, while the NVIDIA card has 24 RT cores. The RTX 4060 AD106 additionally includes 96 tensor cores, a feature the RX 6600 LE lacks entirely, as its tensor core field is null.

Clock speeds show a mixed picture. The RX 6600 LE has a base clock of 1626 MHz and a boost clock of 2495 MHz, with a game clock of 2045 MHz. The RTX 4060 AD106 has a base clock of 1830 MHz and a boost clock of 2460 MHz, with no game clock listed. The NVIDIA card starts higher at base but boosts slightly lower at peak. Memory clocks differ as well: the AMD card runs at 1750 MHz with 14 Gbps effective, while the NVIDIA card runs at 2125 MHz with 17 Gbps effective.

Compute throughput numbers reveal the NVIDIA card's theoretical advantage. The RTX 4060 AD106 delivers 15.11 TFLOPS of FP32 performance, while the RX 6600 LE delivers 8.942 TFLOPS. The NVIDIA card is 69% higher in raw FP32 throughput. FP16 performance tells a different story: the RX 6600 LE achieves 17.88 TFLOPS at a 2:1 ratio, whereas the RTX 4060 AD106 achieves 15.11 TFLOPS at a 1:1 ratio. The AMD card actually leads in FP16 throughput despite its smaller shader count, thanks to the 2:1 ratio that doubles its FP16 rate.

Pixel and texture rates favor the AMD card. The RX 6600 LE produces 159.7 GPixel/s and 279.4 GTexel/s, while the RTX 4060 AD106 produces 118.1 GPixel/s and 236.2 GTexel/s. The AMD card leads by 35% in pixel rate and 18% in texture rate, driven by its higher ROP and TMU counts combined with a higher boost clock.

The Verdict

The data cannot support a performance verdict between these two cards because the RTX 4060 AD106 has no recorded benchmark scores. The RX 6600 LE stands as a measured product with an average score of 70,829 and a 91st percentile ranking. The RTX 4060 AD106 shows a 50th percentile ranking and an average score of zero, which indicates missing data rather than a literal performance of zero.

From the architectural specifications, the RTX 4060 AD106 appears designed for higher raw compute throughput, with 15.11 TFLOPS FP32 versus 8.942 TFLOPS for the AMD card. The NVIDIA card also uses a denser 5 nm process and includes tensor cores for AI workloads. However, the AMD card counters with higher pixel and texture rates, more ROPs, more RT cores, and a higher FP16 throughput of 17.88 TFLOPS versus 15.11 TFLOPS.

The production statuses differ: the RX 6600 LE is listed as Active, while the RTX 4060 AD106 is End-of-life. The release dates show the AMD card launched on 2023-12-07, and the NVIDIA card on 2024-03-31, making the RTX 4060 AD106 the newer product by about four months. Both cards share the same memory configuration of 8 GB GDDR6 on a 128-bit bus, though the NVIDIA card has higher memory bandwidth at 272.0 GB/s versus 224.0 GB/s.

The power draw favors the NVIDIA card on paper: 115 W TDP versus 132 W for the AMD card, both with a suggested 300 W PSU. The RTX 4060 AD106 uses a 1x 12-pin power connector, while the RX 6600 LE uses a 1x 8-pin connector. Both are dual-slot cards with identical display outputs of 1x HDMI 2.1 and 3x DisplayPort 1.4a. API support is identical across DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

From the recorded data, the RX 6600 LE wins in the only category where direct measurements exist: benchmark scores. Its average of 70,829 and 91st percentile ranking give it a clear statistical presence, while the RTX 4060 AD106 has no scores to compare. The RX 6600 LE also wins in pixel rate (159.7 GPixel/s versus 118.1 GPixel/s), texture rate (279.4 GTexel/s versus 236.2 GTexel/s), FP16 throughput (17.88 TFLOPS versus 15.11 TFLOPS), ROP count (64 versus 48), RT core count (28 versus 24), and TMU count (112 versus 96). Its production status of Active means it remains available, and it has recorded dimensions of 190 mm length, 110 mm height, and 40 mm width.

The RTX 4060 AD106 wins in raw compute specifications. Its FP32 throughput of 15.11 TFLOPS exceeds the RX 6600 LE's 8.942 TFLOPS by a wide margin. It has 3,072 shading units versus 1,792, giving it 71% more shader processors. The 5 nm process node and 121.8M / mm² transistor density show a more advanced manufacturing technology compared to the 7 nm and 46.7M / mm² of the AMD card. Memory bandwidth favors the NVIDIA card at 272.0 GB/s versus 224.0 GB/s, and its 17 Gbps effective memory clock outpaces the AMD card's 14 Gbps. The RTX 4060 AD106 also includes 96 tensor cores, which the RX 6600 LE does not have. Its TDP of 115 W is lower than the AMD card's 132 W, and its base clock of 1830 MHz is higher than the RX 6600 LE's 1626 MHz.

The use-case split follows the data. For workloads that rely on pixel throughput, texture filtering, FP16 compute, or ray tracing core counts, the RX 6600 LE shows an advantage in the recorded specifications. For workloads that emphasize FP32 compute, shader count, tensor core acceleration, or memory bandwidth, the RTX 4060 AD106 has the specification advantage. The lack of benchmark data for the NVIDIA card prevents any confirmation of real-world performance, so these wins remain theoretical based on architecture and specification differences alone. The RX 6600 LE's measured results and active status make it the only one of the two with verified performance in the database.
