I've been putting off buying a laptop for almost two years because I've been waiting for the 32nm CPU's to come out. I'm a bit confussed here though, hopefully someone can clarify. It's seem that the top 2 (best performance) 32nm CPU's are the i7-620M, and the i5-540M, but they both only have 2 cores (w/ integrated graphics). I have it in my head that the more cores, the better (for games and running multiple applications at the same time), but is that the case here? Since the i7-620M has a higher clock speed then any of the Core-i7 mobiles. I thought that these new 32nm would offer better performance then the 45nm? Will Intel release any 4-core 32nm CPU's soon, for those of us who prefer to have a discrete GPU; say AMD's Mobility 5800 series? My main concern is, what will offer me better performance, the older 45nm 4-core CPU's, or the new 32nm 2-core (w/ integreated graphics) CPU's. (Plus a discrete GPU) How does the i7-620M(32nm), compare to the i7-920XM and i7-820QM? Here are the links of the CPU's I'm refering to: http://www.intel.com/consumer/products/processors/corei7-specs.htm http://www.intel.com/consumer/products/processors/corei7-extreme-specs.htm If anyone can clear this up for me that would be great. Thanks. Mike.
less nm means less wattage needed to be used, and maybe faster speeds; but that is not the only reason why. i think you should get yourself a new laptop, if thats what you want to do. just keep in mind although the 'extreme' chips are good, they are WAY expensive, generally.
Yeah, that was one of the reasons I'm staying away from the 45-nm CPU's, there has been CPU's with clock speeds way over 2.00Ghz for a long time, and the only 45-nm that has a near clock speed of that is the "extreme" one, and that cost $1000+ to upgrade on most sites. I guess I can wait a bit long till the 4-core 32nm come out, but I heard that might be next year, or maybe I'll wait for some benchmarks on the new 32nm's.
