AMD Radeon RX 6600 LE vs NVIDIA GeForce RTX 3050 A Mobile Comparison

Where Each One Wins

The recorded benchmark data splits these two GPUs into entirely different performance strata. The AMD Radeon RX 6600 LE wins the only direct head-to-head comparison available, the Geekbench OpenCL test, with a score of 69,229 against 52,998 for the NVIDIA GeForce RTX 3050 A Mobile. That is a 30.6% advantage for the AMD part. In the database's overall percentile ranking, the RX 6600 LE sits at the 91st percentile of all GPUs, while the RTX 3050 A Mobile ranks at the 44th percentile. This is not a close contest; the AMD card occupies a much higher tier of absolute performance.

The RX 6600 LE also shows a higher average benchmark score of 70,829 across all recorded tests, compared to 8,746 for the NVIDIA part. That average is heavily influenced by the NVIDIA GPU's additional DirectX and 2D tests, which drag its mean down. The AMD card's two recorded scores, 69,229 in OpenCL and 72,428 in Vulkan, are both far above anything the RTX 3050 A Mobile achieves in any single test. The NVIDIA GPU's best recorded result is 11,664 in PassMark G3D, which is still substantially lower than the AMD card's weakest score.

For specific workloads, the RX 6600 LE wins in compute-heavy OpenCL tasks by a clear margin. The NVIDIA GPU does have its own strengths in legacy DirectX tests: it scores 152 in PassMark DirectX 9, 94 in DirectX 11, and 61 in DirectX 10, plus 55 in DirectX 12. These numbers are not comparable to the AMD card's scores because different test suites are involved, but they do show the RTX 3050 A Mobile can execute older graphics APIs. The AMD part has no recorded DirectX scores, so the data cannot confirm whether it would outperform the NVIDIA part in those specific legacy tests. What the data does confirm is that in the one test where both GPUs were measured under identical conditions, the AMD card wins decisively.

Architecture Differences

The two GPUs come from different manufacturers, process nodes, and architectural generations. AMD uses the Navi 23 chip built on RDNA 2.0 architecture, fabricated on a 7 nm TSMC process. The die measures 237 mm² and contains 11,060 million transistors, giving a transistor density of 46.7 million per mm². NVIDIA counters with the GA106 chip on Ampere architecture, built on Samsung's 8 nm process. That die is larger at 276 mm², with slightly more transistors at 12,000 million, but the density is lower at 43.5 million per mm² due to the larger process node.

The memory subsystems differ significantly. The RX 6600 LE uses 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The RTX 3050 A Mobile has only 4 GB of GDDR6 on the same 128-bit bus width, resulting in 192.0 GB/s of bandwidth. The AMD card's memory clock is listed at 1750 MHz with 14 Gbps effective, while the NVIDIA part runs at 1500 MHz with 12 Gbps effective. The AMD card also has a higher boost clock of 2495 MHz versus 1343 MHz for the NVIDIA GPU, and a higher base clock of 1626 MHz versus 1065 MHz.

Compute resources show a mixed picture. Both GPUs have 1,792 shading units, but the RX 6600 LE has 112 texture mapping units and 64 ROPs, while the RTX 3050 A Mobile has only 56 TMUs and 32 ROPs. The AMD card's pixel rate is 159.7 GPixel/s and texture rate is 279.4 GTexel/s, both far above the NVIDIA part's 42.98 GPixel/s and 75.21 GTexel/s. In ray tracing, the RX 6600 LE has 28 RT cores, exactly double the 14 RT cores in the RTX 3050 A Mobile. The NVIDIA GPU does include 56 tensor cores, which the AMD card lacks entirely. Floating point performance is also lopsided: the RX 6600 LE delivers 8.942 TFLOPS FP32 and 17.88 TFLOPS FP16 (2:1 ratio), while the RTX 3050 A Mobile delivers 4.813 TFLOPS for both FP32 and FP16 (1:1 ratio).

Power and physical design differ dramatically. The RX 6600 LE has a TDP of 132 W, requires a single 8-pin power connector, and is a dual-slot card measuring 190 mm in length. The RTX 3050 A Mobile has a 45 W TDP, uses no external power connectors, and is an IGP (integrated graphics processor) with dimensions listed as portable device dependent. The AMD card requires a 300 W suggested PSU; the NVIDIA part lists no such requirement. Both use PCIe 4.0 x8 interfaces and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs also differ: the RX 6600 LE has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RTX 3050 A Mobile's outputs are portable device dependent.

The Verdict

The data clearly separates these two products into different performance classes. The AMD Radeon RX 6600 LE is a desktop graphics card with active production status, released on December 7, 2023. It ranks in the 91st percentile of all GPUs and delivers a 30.6% higher OpenCL score than the RTX 3050 A Mobile. Its 8 GB memory capacity, higher bandwidth, double the ROPs and TMUs, and more than double the FP32 throughput make it the stronger choice for any compute or graphics workload measured in the database.

The NVIDIA GeForce RTX 3050 A Mobile is an end-of-life mobile IGP, released on December 31, 2023. It ranks in the 44th percentile and has an average benchmark score of 8,746, which is less than one-eighth of the AMD card's average. Its 45 W TDP and lack of external power connectors indicate it is designed for low-power portable systems, not desktop performance. The presence of 56 tensor cores gives it a feature the AMD card does not have, but no benchmark in the database measures tensor core performance.

For a desktop system where performance is the priority, the data supports the RX 6600 LE without qualification. For a low-power mobile implementation, the RTX 3050 A Mobile is the only option of the two because it is designed for that form factor. The RX 6600 LE's dimensions and power requirements preclude mobile integration. The verdict is not about which GPU is "better" in a vacuum; it is about matching the hardware to the intended use case. The data shows the AMD card wins every direct comparison, but the NVIDIA part occupies a niche the AMD card cannot fill.

Head-to-Head Benchmarks

The only direct head-to-head benchmark in the database is Geekbench OpenCL. The AMD Radeon RX 6600 LE scores 69,229, and the NVIDIA GeForce RTX 3050 A Mobile scores 52,998. The delta is 30.6% in favor of AMD. This is the largest and only direct comparison available, and it shows a substantial performance gap.

Looking at the nearest rivals for each GPU provides additional context. The RX 6600 LE's closest competitor is the NVIDIA RTX A3000 Mobile, which scores 70,140 and is 1% behind the AMD card. The AMD Radeon RX 6650M scores 71,768 and is 1.3% ahead of the RX 6600 LE. The NVIDIA Quadro P6000 scores 69,986 (1.2% behind), and the AMD Radeon Pro WX 8200 scores 69,870 (1.4% behind). These results place the RX 6600 LE in a tight cluster of high-end GPUs, all within roughly 1.4% of each other.

The RTX 3050 A Mobile sits in a very different competitive neighborhood. Its closest rival is the NVIDIA GeForce GTX 460 v2, which scores 8,743, essentially identical to the RTX 3050 A Mobile's 8,746 (0% delta). The NVIDIA Quadro P2200 scores 8,686 (0.7% behind), while the AMD Radeon R9 M265X scores 8,851 (1.2% ahead) and the AMD Radeon Pro WX 5100 scores 8,863 (1.3% ahead). The RTX 3050 A Mobile's average score is roughly 12% of the RX 6600 LE's average, and its nearest rivals are all older or lower-tier products.

The RX 6600 LE also shows a strong Vulkan score of 72,428, which is higher than its OpenCL score. No Vulkan score is recorded for the RTX 3050 A Mobile, so a direct comparison in that API is not possible. The NVIDIA part has multiple PassMark scores, but none approach the AMD card's numbers. The RTX 3050 A Mobile's best PassMark result, 11,664 in G3D, is still 83% lower than the RX 6600 LE's lowest recorded score. This complete absence of overlap in performance ranges confirms that the two GPUs are not competitors in the same tier. The data indicates the RX 6600 LE is a mid-to-high-end desktop part, while the RTX 3050 A Mobile is a low-power mobile solution with legacy API support.
