Armed with an extra 32 shaders (taking total count from 480 up to 512), the card, as expected, shows roughly a 6 per cent performance increase across most gaming benchmarks.
What's more interesting, though, are the associated temperatures and power-draw numbers.
According to the review, the 512-core card hits 94°C after just five minutes of Furmark stress testing, and power consumption rises right the way up to 644W. That's an incredible 204W (50.9 per cent) more than a standard 480-core card.
Something wrong with the numbers? Or is this early power-hungry sample just not ready for public consumption?
Who knows, but we feared the worst on seeing the card's two eight-pin PCIe power connectors.
