JEMC said: If what AMD said is true, the Nano will be slower than a 290X. The Nano uses 175W and Fiji offers "50% higher performance per Watt" compared to 290X. Given that the 290X uses 290W, the maths say that Nano uses 60% of the 290X total power (175/290 = 0.6) plus 50% more performance per Watt = 0.6 x 1.5 = 0.90 So Nano gives about 90% of the performance of a 290X. |
But the slide says "up to 2X higher performance per watt". Shouldnt it be more powerful than the 290x
