Both cards share an identical base GPU clock speed of 2295 MHz, meaning they start from the same foundation under standard load. The real divergence appears under sustained boost conditions: the ProArt RTX 5080 reaches a turbo of 2617 MHz versus 2452 MHz for the ProArt RTX 5070 Ti — a roughly 6.7% higher ceiling that, combined with its substantially larger shader array, translates into meaningfully wider headroom during demanding workloads.
The 5080′s advantages compound across every throughput metric. Its 10,752 shading units versus 8,960, 336 TMUs versus 280, and 112 ROPs versus 96 collectively represent around a 20% wider execution pipeline. In practice, this shows up in raw compute: the 5080 delivers 56.28 TFLOPS of floating-point performance against 43.94 TFLOPS — a ~28% gap that matters significantly for GPU-accelerated rendering, AI inference, and simulation workloads. Its texture throughput advantage (879.3 GTexels/s vs 686.6 GTexels/s) follows the same proportion, meaning higher-resolution and more texture-heavy scenes are handled more comfortably. The 5080 also edges ahead on memory bus speed (1875 MHz vs 1750 MHz), which helps feed that larger shader array without bottlenecking. Both cards support Double Precision Floating Point (DPFP), making neither meaningfully superior for professional FP64 tasks on that criterion alone.
The ProArt RTX 5080 holds a clear and consistent performance advantage in this group across every measurable dimension — compute throughput, texture fill rate, pixel output, and memory speed. The 5070 Ti is not uncompetitive in absolute terms, but users prioritizing peak rendering or compute performance will find the 5080′s ~20–28% wider pipeline a tangible, real-world difference rather than a marginal one.
