So what sort of power requirements will come with these new ultrafast mobile GPUs? Here is one more area where things have improved over the GeForce Go 7950 GTX. Maximum power use should be somewhat lower (37W compared to 44W for the 8800M GTX, and a few watts lower for the 8800M GTS), and minimum power requirements should also be lower - we were told the 8800M GTX sitting idle at the Windows desktop consumes 4.7W. VP2 will increase power requirements slightly when watching movies, but only up to around 7.2W. While the idle power consumption isn't particularly high, the fact of the matter is that battery life is extremely important for many laptop users, and battery life will still suffer compared to IGP laptop offerings.
