Both the RTX 5070 Ti Phoenix-S GS and the RTX 5080 Phoenix share an identical base GPU clock of 2295 MHz, meaning neither card holds an advantage at its guaranteed sustained frequency. However, the 5080 Phoenix pulls ahead under boost conditions, reaching a turbo of 2617 MHz versus 2482 MHz — a 135 MHz gap that reflects a more capable power and thermal headroom, allowing the 5080 to sustain higher frequencies during demanding workloads.
The more telling performance story lies in the raw compute resources. The 5080 Phoenix fields 10,752 shading units, 336 TMUs, and 112 ROPs, compared to 8,960 shaders, 280 TMUs, and 96 ROPs on the 5070 Ti. This translates directly into the headline figures: the 5080 delivers 56.28 TFLOPS of floating-point throughput versus 44.48 TFLOPS — roughly a 27% advantage — and a texture rate of 879.3 GTexels/s against 695 GTexels/s. In practice, this means the 5080 handles geometry-heavy scenes, complex shaders, and high-resolution rendering pipelines with meaningfully more headroom before hitting a GPU-bound ceiling.
The 5080 Phoenix also edges ahead on memory bandwidth potential with a faster GPU memory speed of 1875 MHz versus 1750 MHz, which feeds its larger shader array more efficiently. Both cards support Double Precision Floating Point, making them equally capable for GPGPU or compute workloads that require DPFP. Overall, the 5080 Phoenix holds a clear and consistent performance advantage in this group across every major throughput metric, with the gap being most significant in raw compute and rasterization capacity.
