The clock difference is somewhat enormous when looking between the two, at more than 100MHz faster on the higher-end model. This isn’t just the PCB and VRM – it barely is, in fact – it’s the boosting behavior from the silicon quality and the cooler quality. A higher-end cooler with lower operating thermals allows the GPU to hit higher frequencies at lower voltages, pursuant to NVIDIA’s Boost 4.0 stepping. The silicon quality difference is somewhat apparent, if you go back to our first two OC stepping charts in this review.
