AMD Radeon RX 6600S vs NVIDIA GeForce RTX 3050 Ti Mobile Comparison

Where Each One Wins

The benchmark data splits cleanly in favor of the AMD Radeon RX 6600S. Across every recorded head-to-head test, the AMD part takes the win: eight tests, eight victories. The NVIDIA GeForce RTX 3050 Ti Mobile does not claim a single benchmark in the database comparison. That makes the use-case split straightforward: if the workload is covered by the benchmarks recorded here, the RX 6600S is the stronger pick.

The RX 6600S wins by the largest margins in legacy DirectX 9 workloads, where it scores 176 versus the RTX 3050 Ti Mobile's 120, a 31.8% gap. DirectX 11 also favors AMD heavily, with a 105 to 76 result, a 27.6% lead. For newer API workloads, the margin narrows: DirectX 12 shows a 56 to 49 result, a 12.5% gap, while the Geekbench OpenCL test shows a 66,435 to 57,915 result, a 12.8% lead. The AMD card's smallest win comes in GPU compute, where it scores 4,879 versus 4,305, an 11.8% advantage.

For the RTX 3050 Ti Mobile, the practical takeaway is that it remains competitive in modern API scenarios but falls behind in legacy and general compute tasks. Its PassMark G3D score of 10,093 sits well below the RX 6600S's 12,649, a 20.2% deficit. The G2D score tells a similar story: 498 versus 647, a 23% gap. The NVIDIA part's best relative showing is in DirectX 12 and OpenCL, where the deficit shrinks to roughly 12-13%, suggesting it is less outclassed in newer, compute-oriented workloads.

FAQ

Q: Which GPU wins more benchmarks in the database?

A: The AMD Radeon RX 6600S wins all eight head-to-head tests recorded. The NVIDIA GeForce RTX 3050 Ti Mobile records zero wins.

Q: How large is the performance gap in DirectX 12?

A: The RX 6600S scores 56 in PassMark DirectX 12, while the RTX 3050 Ti Mobile scores 49. That is a 12.5% lead for AMD.

Q: Where does the RTX 3050 Ti Mobile come closest to the RX 6600S?

A: The smallest gaps are in PassMark DirectX 12 (12.5%) and PassMark GPU compute (11.8%). In both cases, the AMD part still wins, but the margin is far narrower than in older DirectX tests.

Q: Are both GPUs limited to 4 GB of memory?

A: Yes, both use 4 GB of GDDR6 on a 128-bit bus. The AMD part has a higher memory bandwidth at 224.0 GB/s versus 192.0 GB/s for NVIDIA.

Q: Which GPU has the higher average benchmark score in the database?

A: The NVIDIA part has a higher average benchmark score of 12,940, despite losing every head-to-head test. The RX 6600S averages 10,629. This reflects the different benchmark suites each card was tested with, not a contradiction in the head-to-head results.

Q: How do the two GPUs rank against all GPUs in the database?

A: The RTX 3050 Ti Mobile sits at the 53rd percentile, while the RX 6600S sits at the 49th percentile. Their nearest rivals also differ: NVIDIA's closest match is the GTX 1660 SUPER at 0.4% behind, while AMD's closest is the Radeon R9 M275X at 0.4% ahead.

Head-to-Head Benchmarks

The recorded head-to-head data shows a consistent pattern of AMD dominance, but the magnitude varies significantly by test. The largest single win for the RX 6600S is in PassMark DirectX 9, where it scores 176 against the RTX 3050 Ti Mobile's 120. That 31.8% gap is nearly triple the margin seen in DirectX 12. DirectX 11 follows closely, with AMD leading 105 to 76, a 27.6% difference. DirectX 10 shows a 81 to 60 result, a 25.9% lead.

The 2D performance gap is also substantial. The RX 6600S scores 647 in PassMark G2D, while the NVIDIA part scores 498, a 23% deficit. In 3D performance, the PassMark G3D test shows the RX 6600S at 12,649 versus 10,093, a 20.2% lead. The RX 6600S also wins the OpenCL compute test with 66,435 points against 57,915, a 12.8% margin, and the GPU compute test with 4,879 against 4,305, an 11.8% margin.

The narrowest victory for AMD is in DirectX 12, where the RX 6600S scores 56 and the RTX 3050 Ti Mobile scores 49, a 12.5% gap. Notably, this is the only test where the NVIDIA part scores above half of the AMD result. Across all tests, the RTX 3050 Ti Mobile's relative performance is worst in legacy DirectX 9 and best in modern API and compute tasks. This suggests the NVIDIA architecture handles newer workloads proportionally better, even though it still loses every matchup.

Specification Differences

The two GPUs differ in nearly every core specification category. The RTX 3050 Ti Mobile uses 2,560 shading units, while the RX 6600S uses 1,792. Despite fewer shading units, the AMD part has more texture mapping units (112 versus 80) and more render output units (64 versus 32). The NVIDIA part has 20 ray tracing cores and 80 tensor cores, while the AMD part has 28 ray tracing cores and no tensor cores.

Clock speeds strongly favor AMD. The RX 6600S has a base clock of 1,700 MHz and a boost clock of 2,000 MHz, with a game clock of 1,881 MHz. The RTX 3050 Ti Mobile runs at a 735 MHz base and 1,035 MHz boost. Memory clocks also differ: AMD runs at 1,750 MHz (14 Gbps effective), while NVIDIA runs at 1,500 MHz (12 Gbps effective). This contributes to the bandwidth difference: 224.0 GB/s for AMD versus 192.0 GB/s for NVIDIA.

Rates and throughput favor AMD across the board. The RX 6600S delivers 128.0 GPixel/s and 224.0 GTexel/s, while the RTX 3050 Ti Mobile delivers 33.12 GPixel/s and 82.80 GTexel/s. FP32 throughput is 7.168 TFLOPS for AMD versus 5.299 TFLOPS for NVIDIA. FP16 is a bigger split: the AMD part reaches 14.34 TFLOPS with a 2:1 ratio, while NVIDIA manages 5.299 TFLOPS with a 1:1 ratio.

Power and interface also differ. The RX 6600S has an 80 W TDP, while the RTX 3050 Ti Mobile has a 75 W TDP. The bus interface is PCIe 4.0 x16 for NVIDIA and PCIe 4.0 x8 for AMD. Both are integrated into portable devices with no power connectors and no dedicated display outputs listed.

Architecture Differences

The architectural split is fundamental. NVIDIA uses the Ampere architecture on a Samsung 8 nm process, while AMD uses RDNA 2.0 on a TSMC 7 nm process. The die sizes are similar but not identical: NVIDIA's GA106 chip measures 276 mm² with 12,000 million transistors, while AMD's Navi 23 measures 237 mm² with 11,060 million transistors. Transistor density slightly favors AMD at 46.7M per mm² versus 43.5M per mm².

The NVIDIA chip is built around its tensor core design, which powers features like DLSS, while the AMD part has no tensor cores at all. Instead, the RX 6600S relies on a higher count of ray tracing cores (28 versus 20) and a markedly different compute layout. The AMD architecture achieves higher FP16 throughput through a 2:1 ratio, effectively doubling its FP32 rate, whereas NVIDIA runs FP16 at a 1:1 ratio with FP32.

Memory architecture is identical in capacity and bus width, but AMD's higher memory clock yields a 16.7% bandwidth advantage. The RX 6600S also has double the ROP count, which explains its much higher pixel rate (128.0 GPixel/s versus 33.12 GPixel/s). The texture rate advantage is similarly lopsided: 224.0 GTexel/s versus 82.80 GTexel/s.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates differ by roughly eight months, with NVIDIA launching in May 2021 and AMD in January 2022. Both are end-of-life products. The NVIDIA predecessor is GeForce 20 Mobile, while AMD's is Polaris Mobile.

The Verdict

The data is unambiguous: the AMD Radeon RX 6600S wins every recorded benchmark against the NVIDIA GeForce RTX 3050 Ti Mobile. The RX 6600S's advantages are largest in legacy DirectX 9 and 11 workloads, where it leads by 27% to 32%, and smallest in DirectX 12 and compute tasks, where it leads by 12% to 13%. Anyone prioritizing modern API performance will find the AMD card still ahead, just by a narrower margin.

The RTX 3050 Ti Mobile is not without merit. Its tensor cores enable NVIDIA-specific features, and its higher average benchmark score (12,940 versus 10,629) plus 53rd percentile ranking indicate it competes well against the broader GPU field. But in direct comparison, the RX 6600S simply produces higher scores across the board.

For a buyer choosing between these two specific mobile GPUs, the RX 6600S is the stronger performer in every test recorded here. The RTX 3050 Ti Mobile's best case is a workload that leans heavily on DirectX 12 or OpenCL, where it trails by roughly 12%, rather than the 20-32% deficits seen elsewhere. The AMD card's higher TDP (80 W versus 75 W) is a modest trade for the performance it delivers. Based strictly on the database measurements, the RX 6600S is the pick for anyone who wants the higher benchmark scores, while the RTX 3050 Ti Mobile remains the choice only if NVIDIA-specific features or its broader average score ranking matter more than direct head-to-head results.
