Last week Tom’s Hardware had the opportunity to sit down with Gigabyte’s technical team in Taiwan and discuss motherboards, energy efficiency and the competition. Gigabyte’s technical team wasted no time in jumping into charts, benchmarks and comparisons with its main competitor, Asus. Gigabyte’s technical manager spent time comparing several motherboards from both Gigabyte and Asus, specifically those that claim good power to performance efficiency ratios. When the slides were shown, the message from Gigabyte’s technical team was obvious: Asus outright lied about its performance figures.

According to Asus’ own documents, motherboards labeled with an EPU logo contain an "Asus Energy Processing Unit." Essentially, these motherboards are supposed to contain components designed specifically to lower power consumption and provide better electrical efficiency throughout — there’s really no logical "processor" involved. Asus claims that EPU motherboards can deliver up to 80.23-percent "power savings" from motherboards without EPU components.
