The M90p is a big improvement over the M58p when it comes to idle power, beating it by 14W, a 34% improvement. It also is more frugal on load, when asleep and turned off altogether. Given how much performance it packs, its energy efficiency is superb.

The ThinkStation E20 tower which has a similar processor to the M90p actually runs neck and neck with the older M58p despite because its power consumption is hampered by a Nvidia Quadro graphics card.

While the M58p has fairly fast processor in the Core 2 Duo E8400, it is no match for a Core i5. The M90p and ThinkStation E20 both hand the M58p a resounding defeat in every test except file archiving with WinRAR. The M90p also used less power during the tests than both of the other machines.
