Power Measurement Results In Ups And Downs
As you can see, the Enhanced Halt Mode makes a huge difference in our tests. Only 23 W power loss in idle mode makes the new P4-570 shine much brighter than the old P4-560 with its 38 W loss.
Also notable are the amazing results for AMD's latest 90 nm Winchester Athlons, considering that these are not much slower than the Intel top models in terms of gaming performance.
Under maximum load, the new P4 fulfils its "destiny", reaching a higher thermal loss than ever before: it is the most energy-demanding desktop processor. Again, it's interesting to see what AMD is able to do at 90 nm: high load does not cause the new chips to run hot at all.
