Wrong. Centrino's have 1mb L2 cache, compared to P4 or P4-M's 512kb. Therefore, they are faster even though their rated speeds are lower. Centrino 1.4Ghz is about equivalent to P4/P4M 2.2Ghz in terms of performance. Power-wise, Centrinos are DESIGNED to consume very low power, it'll last around/more than double the time a P4M can last. Of course, all of this comes for a higher price.
besides HDD will be the bottleneck in laptop so going for P4 doesn't make sense.
Its true HDD's are slower(because of rpm) in laptops. But just because of that doesn't mean P4 won't help compared to a Celeron. P4 is far superior to a celeron, its got added instruction sets, added cache. Try using same system config with 2 equal speed celeron and a P4 to play games, encode/rip movies, and you'll see difference right away.
As far as notebooks with AMD Athlons are concerned, I could see only HP/Compaq having one (Dell, IBM dont have any?)
That's cause alot of ppl these days like big name stuff, big companies prefer to buy products from established companies. Even though AMD has caught up with Intel in terms of performacne these last few years, Intel has always been the bigger company, and so more ppl use their products. Around a year ago, there's also been rumors that Intel in a way forced some PC manufacturers to use their processors instead of AMD. True, rumors aren't always true, but I think its very possible.
Thanks. Now a major decision - The mobile Athlons are roughly $50 (more on some models) cheaper than an equivalent P4 - So do the Pentium-M actually give better (battery) life than the mobile Athlon XPs? And what about the heatsink problems? Does the mobile Athlon have the same heatsink problems as the desktop models do?
It really depends what you intend on using the laptop for, some appz better iwht P4, some better with AMD. You probably won't be doing much gaming anyway, cause most laptops have integrated video cards. WHen u say heatsink problem, do you mean crushing core on the Athlon's? If so, then I wouldn't see it happening unless you really intend on opening up the laptop. Battery life will be around same, don't always trust the listed battery life in the specs. Faster processors will always consume more power.
