    As the title says. I am looking for an average or mean battery life gain by using a 25 watt P series 2 core vs a 45 watt quad core cpu? Also how big a difference in temperatures would each run? The sager NP8662 is adding the t9900 and the p9700 (3.06ghz 35 watt + 2.8ghz 25 watt) They both have IDA which means the 2.8ghz P series will run a single core at 3.0ghz if an application is single threaded, and all for only 25 watts. But i am babbling now. I just really need to know the average battery life savings of 45w quad vs 25 watt twin core.

    What will you be doing? The power usage difference will be small at idle, but much greater at load. Also give some idea of your other specs.

    15.4" screen 1680 x 1050, 4GB OCZ 1066 DDR3 RAM, 256GB OCZ Vertex SSD, 1GB Geforce GTX 260m, Vista Ultimate x64 SP2, Echo Indigo IoX express card Sound, 8x DVD-RW DL w/ lightscribe, bluetooth and a/b/g/n wireless

    I will be using this computer for web browsing, emails, AIM/MSN, School purposes such as Word, Excel, PDF's, Research on encylopedias on cd rom, Medical dictionaries on CD-ROM, Then few certain games I love to play alot, WoW, Warcraft 3, Diablo, Diablo 2, Starcraft, and soon Starcraft 2 and Diablo 3, U torrent for downloading music, tv episodes, dvd's, blu rays to play on my plasma via HDMI output, games, apps and anything else thats free. I also occasionally rip my own dvd's or audio cd's to FLAC.

    I am interested in the q9000 cause I know 4 cores always beat 2 cores (when a program has the required threads) and I got a hold of the KN COP program which gives me a lot of control to utilize all 4 of the cores with full power. But I do need battery power when I'm at school. If the 2.8ghz P9700 with IDA to boost it to 3.0ghz when using 1 core running at 25 watts gives me a decent edge over the 45 watt quad core beast Then I will go with it. Some of my classes are very warm with no a/c and its summer time. I would say the rooms easily getr to 85 degrees ambient. I'm thinking the 25 watt tdp will save me on overheating in hot rooms tat the quad core might not handle. So any ideas on battery gains on those 20 watts?

    None of the programs you use will actually benefit from a quad core, except for the ripping.

    Even then, how much are you going to be ripping while you're on the road or out...
