Default AMD vs. Intel: Battery Life Investigated

Anyone looking to go out and purchase a new laptop is almost certainly interested in a couple things: how much does it cost, and what sort of battery life can you expect? Answering those questions for any specific laptop is simple enough, provided we can get a sample unit for testing. However, it becomes more difficult to answer these questions when you're looking at the big picture -- i.e. AMD vs. Intel laptops. The pricing question is easier: laptops using AMD platforms are (usually) cheaper than equivalent Intel platform laptops. That's simple enough: you're paying more for the Intel brand. But what about battery life?


Considering these systems are as close as we can get to "identical", AMD takes a real pounding in battery life testing. The closest result (the idle test) has the Intel platform providing 20% more battery life, while the best Intel results (DVD playback and heavy web surfing) give about 35% more battery life. Averaging all five results, the Intel-based NV58 delivered 28% more battery life than the AMD-based NV52. Ouch.
