Both cards share the same foundation: identical base clocks of 2280 MHz, the same 3840 shading units, 120 TMUs, 48 ROPs, and matched memory speeds of 1750 MHz. This tells us they are built on the same silicon with the same memory subsystem, meaning any performance gap between them is entirely a product of how aggressively each card is factory-overclocked.
The key differentiator is the boost clock. The Gaming OC reaches 2625 MHz under load, while the Ventus 2X OC tops out at 2527 MHz — a difference of 98 MHz, or roughly 4%. This gap flows directly into every derived throughput metric: the Gaming OC delivers 20.16 TFLOPS of floating-point performance versus 19.41 TFLOPS, a 315 GTexels/s texture fill rate versus 303.2 GTexels/s, and a pixel rate of 126 GPixel/s versus 121.3 GPixel/s. In practice, a ~4% compute advantage rarely translates into a dramatic difference in frame rates, but it can matter at the margins — particularly in GPU-bound scenarios at higher resolutions or with demanding visual settings.
The Gaming OC holds a clear, if modest, performance edge in this group. Both cards support Double Precision Floating Point, which is largely irrelevant for gaming but useful for light compute workloads. If raw throughput is the priority, the Gaming OC is the stronger choice; the Ventus 2X OC trades that small clock speed advantage for what is typically a more compact or cost-optimized cooling design — though that distinction falls outside the scope of these performance specs alone.
