Both cards share an identical foundation: the same 2407 MHz base clock, 4608 shading units, 144 TMUs, and 48 ROPs. This means the underlying silicon is the same, and any performance delta between them comes purely from how aggressively each card is factory-tuned. The standard Prime and the OC Edition are, in essence, the same GPU running at different boost ceilings.
The real differentiator is the GPU turbo clock: the OC Edition reaches 2617 MHz versus 2572 MHz on the standard Prime — a 45 MHz advantage (roughly +1.75%). This directly cascades into every throughput metric: the OC Edition leads with 24.12 TFLOPS of floating-point performance versus 23.7 TFLOPS, a 376.8 GTexels/s texture rate versus 370.4 GTexels/s, and 125.6 GPixel/s pixel rate versus 123.5 GPixel/s. In practice, a ~1.75% clock uplift translates to a similarly marginal gain in real-world frame rates — noticeable in benchmarks, but unlikely to be perceptible in everyday gameplay.
The OC Edition holds a narrow but consistent edge across every performance metric in this group, and it does so without any architectural compromise since memory speed, shader count, and fixed-function units are identical. That said, the advantage is slim by any practical measure. Users who prioritize maximum out-of-the-box performance should lean toward the OC Edition, while those indifferent to single-digit percentage gains will find the standard Prime functionally equivalent.
