At their core, both cards share the same fundamental silicon configuration: 4608 shading units, 144 TMUs, 48 ROPs, and an identical base clock of 2407 MHz. This means the underlying architecture and its theoretical parallelism are identical — the real story here is in the boost frequencies. The standard Infinity 3 tops out at 2572 MHz turbo, while the OC variant pushes that ceiling to 2662 MHz — a 90 MHz delta that flows directly into every derived throughput metric.
That clock advantage translates into a 24.53 TFLOPS floating-point figure for the OC against 23.7 TFLOPS on the standard model — roughly a 3.5% uplift. Similarly, texture throughput rises from 370.4 GTexels/s to 383.3 GTexels/s, and pixel fill rate from 123.5 GPixel/s to 127.8 GPixel/s. In practice, these gains are proportional and consistent: you can expect the OC to sustain marginally higher average framerates and slightly snappier rendering of geometry-heavy or shader-intensive scenes, though the gap is narrow enough that it will rarely be the deciding factor in real-world titles.
The OC variant holds a clear, if modest, performance edge in this group. Both cards share the same memory speed, raster hardware count, and DPFP support, so there are no hidden architectural advantages on either side — the difference is purely clock-driven. Whether that 3–4% headroom justifies the likely price premium depends on the user's sensitivity to top-end throughput, but on raw numbers alone, the Infinity 3 OC is the faster card.
