Asus makes unexplained improvements to EPU

From 58 to 80 percent savings


This week Asus issued yet another press release about its EPU, or Energy Processing Unit, which has suddenly gone from 58.6 percent to 80.23 percent in CPU power savings, despite the same components and hardware being used.

Asus is relying on an IC to do the switching between four and eight power phases which, in contrast to Gigabyte's D.E.S. system, only gives you two modes. D.E.S., on the other hand, is more flexible as it will go from two to as many power phases as there are on the motherboard.

Asus also makes some rather ridiculus statments in the press release. "A Single EPU motherboard is able to save 33,000 watts of electricity after one year´s continuous operation – about 20.7423 KG of reduced CO2 emissions. If 10 Million EPU motherboards are shipped, 207,430,000 KG CO2 can be reduced. In essence, ASUS helps the Earth grow the equivalent of 17,285,833.33 trees in a year." We're not sure that reducing your power usage on your computer really can equate to counting trees, as trees do a lot more than just reduce CO2 in the atmosphere.

Nonetheless, we hope Asus can clarify this mystery for us, as the press release does no such thing. Even more curiously, the P5E3 Deluxe/WiFi-AP@n motherboard on the global website has the updated numbers, while the exact same model on the UK website still has the old numbers. We're not sure we trust Asus on this one, especially as no new BIOS update has been issued this year, and there's no mention of any EPU enhancements in the latest BIOS update for this board.

Take a look at the screenshot below, the insert is the new updated number shown on the Asus EPU mini site.
