Both cards share an identical base GPU clock of 2295 MHz, meaning out-of-the-box frequency is not a differentiator. However, under sustained load the Asus ROG Astral RTX 5080 pulls ahead with a turbo clock of 2640 MHz versus 2512 MHz on the Inno3D RTX 5070 Ti iChill X3 — a roughly 5% boost clock advantage that reflects the 5080's wider thermal and power headroom, and that Asus's ROG Astral cooling solution can sustain those clocks more aggressively.
The more significant gap lives in raw silicon. The RTX 5080 fields 10,752 shading units, 336 TMUs, and 112 ROPs against the 5070 Ti's 8,960 / 280 / 96 — roughly a 20% wider execution engine across the board. Combined with a faster memory bus speed (1875 MHz vs 1750 MHz), this translates directly into the headline numbers: 56.77 TFLOPS of floating-point throughput and a texture fill rate of 887 GTexels/s for the 5080, versus 45.02 TFLOPS and 703.4 GTexels/s for the 5070 Ti. In practice, that ~26% compute and texture advantage means noticeably faster performance in shader-heavy workloads, ray tracing, and AI-accelerated rendering pipelines. The pixel rate gap (295.7 vs 241.2 GPixel/s) similarly favors the 5080 in high-resolution rasterization scenarios.
Both cards support Double Precision Floating Point, which matters for GPGPU and professional compute tasks rather than gaming, so neither holds an edge there. Overall, the RTX 5080 has a clear and consistent performance advantage in this group — not from any single dramatic spec, but from a broader execution unit count and higher sustained clocks that compound into a roughly 20–26% lead across compute, texturing, and fill rate metrics. The 5070 Ti iChill X3 is no slouch, but users who prioritize peak throughput will find the 5080 meaningfully faster.
