Both the Gigabyte WindForce OC SFF and the Inno3D X3 Gaming OC are built on the same RTX 5080 silicon, and it shows: they share identical base clocks of 2295 MHz, the same 10752 shading units, 336 TMUs, 112 ROPs, and 1875 MHz memory speed. This means the vast majority of their compute architecture is functionally equivalent, and both support Double Precision Floating Point — a feature relevant for professional and scientific workloads beyond pure gaming.
The only real differentiator within this group is the GPU boost clock. The Inno3D X3 Gaming OC reaches a turbo of 2700 MHz versus 2670 MHz on the Gigabyte WindForce OC SFF — a gap of just 30 MHz, or roughly 1.1%. This modest difference cascades into equally small gaps across derived metrics: the Inno3D posts 58.06 TFLOPS of floating-point performance versus 57.42 TFLOPS, and its texture rate of 907.2 GTexels/s edges out the Gigabyte's 897.1 GTexels/s. In practice, differences of this magnitude are below the threshold of perception in any real-world gaming or rendering scenario — they fall well within frame-time noise and benchmark variance.
The Inno3D X3 Gaming OC holds a narrow technical edge in peak performance purely due to its higher boost clock, but this advantage is cosmetic rather than meaningful. Users should not expect any measurable difference in games, creative applications, or even most compute tasks. The decision between these two cards should rest on other factors — form factor, cooling solution, acoustics, and price — rather than these near-identical performance figures.
