Where Each One Wins

The benchmark data points to a clear split. The RTX 5070 Ti is the stronger part overall, beating the RX 6600M XT in the single head-to-head test by 63.8%. The RTX card also holds large compute advantages across the board: 4.4x the shader units, 2.5x the TMUs, 1.5x the ROPs, more than twice the RT cores, a 3.5x memory bandwidth advantage, and a larger FP32 throughput.

The RX 6600M XT still has its own territory. It is a mobile part with a 120 W TDP and no external power connectors, which fits IGP form factors. It also has a higher boost clock relative to its base (a 16.8% boost versus 6.8% on the RTX), and its memory clock is closer to its core clock. For applications where the power envelope and the mobile form factor are the primary constraints, the RX 6600M XT remains a coherent choice.

The Verdict

From the recorded data alone, the NVIDIA GeForce RTX 5070 Ti is the pick for workloads that are sensitive to raw performance, ray tracing, and memory bandwidth. It leads by 63.8% in the single head-to-head test, holds a 49,957 point average score advantage, and is in the 86th percentile of all GPUs. The AMD Radeon RX 6650M XT is a lower-power, IGP alternative: it is for systems where power, physical size, and a separate power connector are not viable. The database's recorded measurements show that both are credible options, but they are targeting different segments.
