AMD Radeon RX 6600 LE vs NVIDIA GeForce RTX 4060 Ti AD104 Comparison

AMD Radeon RX 6600 LE and NVIDIA GeForce RTX 4060 Ti AD104 occupy different segments of the graphics card market, and the recorded data reflects that positioning clearly. The RX 6600 LE is an active product from the Radeon RX 6000 series, built on the Navi 23 chip with RDNA 2.0 architecture, while the RTX 4060 Ti AD104 is an end-of-life GeForce 40-series part using the AD104 chip with Ada Lovelace architecture. The RX 6600 LE holds a 91st percentile ranking among all GPUs in the database, with an average benchmark score of 70,829 from two recorded tests, whereas the RTX 4060 Ti AD104 has a 50th percentile ranking and no recorded average score, as its benchmark list is empty.

The Verdict

The data presents a clear distinction in intended usage. The AMD Radeon RX 6600 LE is the only one of the two with measurable benchmark results, scoring 69,229 in Geekbench OpenCL and 72,428 in Geekbench Vulkan. These figures place it in the 91st percentile of all GPUs tracked, indicating strong compute performance for its class. The nearest rivals in the database show how tight this competition is: the NVIDIA RTX A3000 Mobile averages 70,140, which is 1% higher, and the AMD Radeon RX 6650M averages 71,768, which is 1.3% higher. The RX 6600 LE sits slightly above the NVIDIA Quadro P6000 and AMD Radeon Pro WX 8200, both of which trail by 1.2% and 1.4% respectively. This clustering suggests the RX 6600 LE delivers consistent, competitive compute throughput.

The NVIDIA GeForce RTX 4060 Ti AD104, by contrast, has no benchmark entries in the database. Its average benchmark score is recorded as 0, and its percentile rank of 50 reflects that lack of data rather than measured performance. The RTX 4060 Ti AD104 is marked end-of-life, while the RX 6600 LE is active, meaning the AMD part remains a current option. For users selecting between these two based on available measurements, the RX 6600 LE is the only choice with verified performance numbers. The RTX 4060 Ti AD104 offers higher raw specifications on paper, including more shading units, higher clock speeds, and greater FP32 throughput, but those specifications are not backed by any recorded benchmark scores in this database. The verdict from the data is straightforward: the RX 6600 LE delivers measurable, percentile-ranked performance, while the RTX 4060 Ti AD104 remains an unverified entry in terms of actual test results.

Architecture Differences

The two GPUs come from fundamentally different architectural generations. The AMD Radeon RX 6600 LE uses the Navi 23 chip, built on RDNA 2.0 architecture, and is manufactured on a 7 nm process at TSMC. The NVIDIA GeForce RTX 4060 Ti AD104 uses the AD104 chip, built on Ada Lovelace architecture, and is manufactured on a 5 nm process, also at TSMC. The 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 Ti AD104 contains 35,800 million transistors on a die size of 294 mm², yielding a transistor density of 121.8 million transistors per square millimeter. The NVIDIA part packs more than three times the transistors into roughly a 24% larger die, reflecting the denser 5 nm process.

The compute architectures diverge as well. The RX 6600 LE has 1,792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. It does not list any tensor cores. The RTX 4060 Ti AD104 has 4,352 shading units, 136 texture mapping units, 48 render output units, 34 ray tracing cores, and 136 tensor cores. The inclusion of tensor cores on the NVIDIA part indicates dedicated hardware for AI acceleration, a feature absent from the AMD specification. The FP32 performance reflects this difference: the RX 6600 LE delivers 8.942 TFLOPS, while the RTX 4060 Ti AD104 delivers 22.06 TFLOPS, more than double. FP16 performance also differs in implementation. The RX 6600 LE achieves 17.88 TFLOPS with a 2:1 ratio relative to FP32, while the RTX 4060 Ti AD104 achieves 22.06 TFLOPS with a 1:1 ratio, meaning it does not gain a throughput advantage from reduced precision.

Clock speeds show the NVIDIA part running higher. The RX 6600 LE has a base clock of 1626 MHz, a boost clock of 2495 MHz, and a game clock of 2045 MHz. The RTX 4060 Ti AD104 has a base clock of 2310 MHz and a boost clock of 2535 MHz, with no game clock listed. The NVIDIA boost clock is only 40 MHz higher than the AMD part, but its base clock is substantially higher, suggesting a different power and frequency curve. Memory architecture is similar in capacity and bus width: both use 8 GB of GDDR6 memory on a 128-bit bus. The memory clock differs, with the RX 6600 LE running at 1750 MHz (14 Gbps effective) and the RTX 4060 Ti AD104 running at 2250 MHz (18 Gbps effective). This results in a bandwidth gap: 224.0 GB/s for the RX 6600 LE versus 288.0 GB/s for the RTX 4060 Ti AD104, a 28.6% advantage for the NVIDIA part.

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark entries between these two specific GPUs. The head-to-head benchmark list is empty, and the win counts for both sides are zero. This absence of direct comparison data means any analysis must rely on the individual benchmark results and specification differences available in the database.

The RX 6600 LE has two recorded benchmarks. In Geekbench OpenCL, it scores 69,229, and in Geekbench Vulkan, it scores 72,428. The Vulkan score is 4.6% higher than the OpenCL score, indicating that the RDNA 2.0 architecture handles the Vulkan API particularly well. The average of these two scores is 70,829, which places the card in the 91st percentile of all GPUs. The nearest rival data provides context: the NVIDIA RTX A3000 Mobile averages 70,140, a 1% higher score, while the AMD Radeon RX 6650M averages 71,768, a 1.3% higher score. The RX 6600 LE outperforms the NVIDIA Quadro P6000 by 1.2% and the AMD Radeon Pro WX 8200 by 1.4%. These margins are small, indicating that the RX 6600 LE competes in a tight performance band around the 70,000 to 72,000 score range. It is not a dominant performer, but it is not a laggard either; it sits in the middle of its immediate peer group.

For the RTX 4060 Ti AD104, there are no benchmark scores to compare. Its average benchmark score is recorded as 0, and its percentile rank is 50, which is the median position. Without recorded test results, the data cannot confirm whether the RTX 4060 Ti AD104 would outperform the RX 6600 LE in compute workloads. The specification sheet suggests it should, given the higher shading unit count, higher clock speeds, and more than double the FP32 throughput, but no measurement exists to validate that expectation. The database records the absence of evidence, and the analysis must respect that limitation. The RX 6600 LE is the only card in this comparison with verified performance data, and its benchmark results show it performing near the level of mobile workstation GPUs and slightly above older professional cards.

Specification Differences

The two cards differ across nearly every specification category, with the exception of memory capacity, bus width, memory type, slot width, bus interface, display outputs, and API support. Both use 8 GB of GDDR6 memory on a 128-bit bus, both are dual-slot cards, both use a PCIe 4.0 x8 interface, both offer 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs, and both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. These shared specifications mean the cards occupy similar physical and connectivity profiles, but their internal designs differ substantially.
