I'm in the market for a new laptop... I haven't been laptop shopping in YEARS and consequently don't know dick about the mobile processors.

What's the skinny on the Intel Centrino Mobiles vs. the Centrino Duos vs. Celeron vs. AMD Athlon 64s vs. AMD Turion 64s and AMD Sempron?

Everything else on the laptops I'm good with, just don't know anything about the processors. Are the Celeron mobiles as crappy as the desktop models? And is a hard drive with 5400 RPM as a S-ATA drive as quick as a regular 7200 RPM drive? I'll be doing some video editing which normally requires a 7200 RPM drive, and I've heard the SATA drives (which have faster read/write than the ATA drives) are good at 5400, but I don't know anything about that either. Obviously, because of the heat generated from a 7200 RPM drive those are hard to find in a laptop.

Generally the "mobile" processors consume less power, which they do (partly) by being slower.

I've heard really good things about the Intel Core-Duo processors from a buddy that does, well, lots of, uhm, "video editing". Says it transcodes in far less time than any CPU he's had to date.

The Core-Duos are outstanding. AMD has a direct competitor called the Turion... it also is a damn fine CPU. The Intel has the best ratings and performance due to onboard cache.

You can't go wrong with either.

FTR, I wanted to buy a laptop w/ the Core Duo, but the laptop I chose (for various reasons including storage, screen, features, etc.) has Turion 64 x2. I am very pleased with the performance of the laptop! dv6040us

You want a mobile Core 2 duo. It's the latest and greatest from Intel so it's gonna cost you some $$$, but it beats anything AMD has to offer while consuming a lot less energy and producing less heat.

Just for the record-

the celeron is a 1/2 way decent processer for a laptop - if you just plan on doing your basic web browsing/DVD burning/digital pictures on the go/email - you dont need very much and can save some coin going that route-

not to say you dont have the cash to buy what you want but others may not

Really? So the Core Duo is a 64 bit dual core processor like the Turion 64 X2?

Yes.

And it is faster in pretty much every benchmark. This is due to onboard cache... it is, IIRC, quadruple the AMD's on-die cache. It's an excellent processor.

AMD's 64-bit memory architecture is better than Intel's due to removal of the memory controller on the CPU... it removes a bottleneck allowing for direct path access to system buses & memory. This allows the CPU to access memory and buses faster than the Intel cpu, which is still bottlenecked by the memory controller. This bottleneck is not readily apparent however, until you work with memory greater than 64GB. The AMD CPU will support 1TB RAM, whereas the Intel maxes at 64GB.

Both CPUs are very good. The AMD systems are slightly less expensive. Despite what some dumbass fanbois may say, you will not notice a difference between the two. Choose a Turion x2 or Core 2 Duo system that has all the FEATURES you are looking for (RAM, XGA, DVD-RW, SATA hdd {storage}, display size, weight, etc). Like I said before, you can't go wrong with either.

Deleted post due to uninformed outdated knowledge of the Yonah arch.

Edit: Ahhh, I see the new Merom is supposed to be full x86-64. My mistake, going off the original Core Duo specs. Bout time they came around. Maybe now we'll finally see some serious price wars in the EMT64 arena.

Looking at these... all comparable as far as I can tell. Main differences are HD size / RAM.

Most of the AMD Turion 64 X2 were lower on memory or had parallel hard drives.

I bought my laptop at CompUSA... have been most pleased. Only complaint = cannot find drivers for the integrated webcam.

<a href="http://www.compusa.com/products/product_info.asp?product_code=339895&Pn=Pavilion_dv6040us_Notebook">link</a>

I bought it on site for ~$1100.
