At the core, both GPUs share the same fundamental silicon configuration: identical 6144 shading units, 192 TMUs, 80 ROPs, and a matching base clock of 2325 MHz — confirming they are built on the same RTX 5070 die with no architectural shortcuts on either side. The memory subsystem is also a dead tie at 1750 MHz, meaning bandwidth-related workloads like texture streaming or framebuffer throughput will be indistinguishable between the two.
The only meaningful performance divergence comes from the boost clock. The Gigabyte WindForce OC SFF is factory-overclocked to 2542 MHz, while the Palit Infinity 3 targets 2512 MHz — a 30 MHz gap that cascades into small but consistent leads across every throughput metric: 31.24 TFLOPS vs 30.87 TFLOPS in floating-point, 203.4 GPixel/s vs 201 GPixel/s in pixel rate, and 488.1 vs 482.3 GTexels/s in texture throughput. In practice, this translates to roughly a 1% performance delta — noticeable only in synthetic benchmarks, not in real gaming frame rates.
Both cards support Double Precision Floating Point, which matters for compute and professional workloads rather than gaming. Overall, the Gigabyte WindForce OC SFF holds a marginal but factual performance edge in this group, driven entirely by its higher factory boost clock. For a pure performance-on-paper decision, it wins — but the gap is narrow enough that thermal behavior, power delivery, and cooling efficiency (factors outside this group) will likely have a greater real-world impact than the 30 MHz difference.
