All Four GPU's were AMD's HD7970 (Reference Design) and were cooled with LN2 to achieve the clock frequencies. The Core/Memory Clock for all 4 GPU's was maintained at 1610Mhz/1930Mhz at its peak during the Vantage Benchmark in which they accumulated a total score of 83000 Performance Points/ 98000 GPU Score which is impressive.
The Benchmark Setup consisted of a Sandy Bridge-E Core i7 3960X Processor running at 5.6Ghz, Rampage IV Extreme X79 Motherboard, 8Gigs of DDR3 Memory and powered by two Antec True Power Quattro 1200W PSU's.
Following are the benchmark results:
3DMark Vantage Performance Preset:
4-Way HD7970's @1610/1930Mhz - 83761 Performance Marks/ 98278 GPU Score
3DMark 11 Performance Preset:
4-Way HD7970's @1530/1880Mhz - 32728 Performance Marks/ 46628 GPU Score
3DMark 11 Extreme Preset:
4-Way HD7970's @1470/1850Mhz - 17423 Extreme Marks/ 17742 GPU Score
Unigine Heaven DX11 Extreme Preset:
4-Way HD7970's @1550/1950Mhz - 7521.175 Score
Judging these benchmarks one thing's for sure, These 28nm GPU's are beasts in overclocking. Sapphire has already confirmed 1335Mhz Core clocked HD7970 variants with watercooling to be available soon after the launch on 9th January 2012.
