 According to the benchmarks on its official website , the Fastra II is faster and more power efficient than its competitors , including the Fastra I and the <unk> <unk> video card . The benchmarks were performed on the Fastra II , the Fastra I , a 512 @-@ core cluster ( consisting of <unk> <unk> ) , an <unk> <unk> <unk> <unk> card on an Intel Core <unk> 940 <unk> , and on an Intel Core <unk> 940 <unk> itself . The Fastra II is over three times faster than the Fastra I in CT slice reconstruction speed . Although the Fastra II consumes more power than the Fastra I , it 's nearly 3 times as energy efficient as the Fastra I , and over 300 times as energy efficient as the 512 @-@ core cluster . The video cards run at 37 degrees <unk> when idle , and at 60 degrees <unk> at full load .
