In real life computer works at full power only in a small part of time, frequently the processor and video card consume much less electric power then the declared in the maximum characteristics.
AMD representatives attempted to prove that such powerful configuration using the Radeon HD 4890 and Phenom II X4 955 Black edition in the daily activity can be more economical than their predecessors or less productive analog. According to AMD, the video card radeon HD 4890 in the rest state consumes 60 W - this is one and half times less than the Radeon HD 4870. The processor phenom II X4 955 Black edition due to the more economical setting of intermediate energy states can consume not more than 42,1 W at the frequency of 800 MHz - this up to 14% less than the energy consumption of phenom II X4 940 Black edition model.
As you see, in all intermediate energy states the processor phenom II X4 955 Black edition is more economical than its predecessor. Actually, the combination of processor phenom II X4 940 (3.0 GHz) Black edition and radeon HD 4770 video card in the rest state consumes 7 W more power than the combination of processor phenom II X4 955 (3.2 GHz) Black edition and video card radeon HD 4890. Certainly, this arrangement will changes under load, but we cannot fail to recognize the superiority of new high end AMD processor in the energy-economy sphere. Related Products :
