At their core, both the Gigabyte WindForce SFF and the Inno3D X3 Gaming OC are built on the same RTX 5080 silicon, sharing identical base specs: a 2295 MHz base clock, 10752 shading units, 336 TMUs, 112 ROPs, and 1875 MHz memory speed. This means the vast majority of their raw compute infrastructure is equivalent out of the box.

The meaningful divergence lies in the boost clock. The Inno3D X3 Gaming OC reaches a 2700 MHz turbo versus the Gigabyte WindForce SFF's 2617 MHz — an 83 MHz advantage. While that gap sounds modest in isolation, it translates directly into higher derived metrics: the Inno3D edges ahead with a 58.06 TFLOPS floating-point throughput versus 56.28 TFLOPS, a 907.2 GTexels/s texture rate versus 879.3, and a 302.4 GPixel/s pixel rate versus 293.1. In practice, these differences represent roughly a 3% performance uplift across compute-heavy and rendering workloads — noticeable in sustained GPU-accelerated tasks or when pushing high frame rates at 4K.

The Inno3D X3 Gaming OC holds a clear, if modest, performance edge in this group, entirely owing to its higher factory boost clock. The Gigabyte WindForce SFF is not meaningfully slower for typical gaming use, but users prioritizing peak theoretical throughput — particularly in GPU compute, 3D rendering, or competitive high-refresh gaming — will find the Inno3D's higher turbo ceiling the more capable card on paper.

Comparison Summary & Verdict

Both cards are built on the same Blackwell architecture and share identical memory, ports, TDP, and feature sets, making them very evenly matched at their core. The differentiating factor is the Inno3D GeForce RTX 5080 X3 Gaming OC, which pulls ahead with a higher GPU turbo clock of 2700 MHz versus 2617 MHz, yielding a better pixel rate, texture rate, and floating-point performance of 58.06 TFLOPS. The Inno3D also adds RGB lighting for builders who value visual flair. The Gigabyte GeForce RTX 5080 WindForce SFF, slightly larger in dimensions, delivers the same foundational experience with a cleaner, no-RGB aesthetic. If maximising out-of-box boost performance and illuminated aesthetics are priorities, the Inno3D is the stronger pick; if a understated look is preferred and the small clock delta is inconsequential, the Gigabyte remains a fully capable choice.
