Benchmarks I
The HG10 and H75 combo gains a slight advantage over Raijintek’s Morpheus in 3DMark due to a higher memory clock. The increase in performance availed by a reduction in thermal throttling is evident when compared to the reference cooler.
Bioshock Infinite reveals a similar narrative to 3DMark. The HG10 and H75 deliver virtually identical performance to the Raijintek Morpheus. What's really telling is the performance improvement over the also-overclocked reference card, most likely due to no thermal throttling.
Noise output is higher than the Raijintek Morpheus since the fans bundled with Corsair’s H75 have a wider RPM range and higher starting RPM. Interestingly, idle and load noise were identical, and the fact the H75 funnels heat straight out the back of the case is the reason for this.
The Raijintek Morpheus, on the other hand, expels all the heat inside the case which causes other components to heat up and require higher fan-speed operation. But even so, the Morpheus remains quieter at full gaming load. Both aftermarket solutions are way, way better than the reference cooling with respect to noise.
Power consumptions exhibits behaviour we also observed with Nvidia’s GeForce GTX 780 Ti. That is, under stock-clock speeds power consumption declines due to lower operational temperatures and reduced fan speeds. At overclocked load, we see the reverse scenario: power consumption increased because thermal constraints are removed and thus allow higher clock speeds.
