Laptop CPUs - 3 to compare

A couple laptop CPUs to be compared, if you would be so kind. (Where do you guys learn all this stuff?)

Contender #1:
Intel Core 2 Duo E6850 3.0 Ghz 4mb cache - 1333mhz FSB
Contender #2:
Intel Core 2 Duo QUAD Q6700 2.66 ghz 8mb cache - 1066mhz FSB
Conteder #3:
Intel Core 2 Duo EXTREME X6800 2.93 ghz 4mb cache - 1066mhz FSB

This paired up with dual 8700 GTs GDDR3 512mb and 4GB of ram

What CPU is the better choice? Maybe you can see why a newbie like me is confused.. they all have different speeds, cache sizes, and FSBs whatever those might be. That's also in price order. The EXTREME is 500 bucks more than the QUAD, 750 more than the other Duo.

Thanks, as always!

 

none of them are laptop cpu's.
some manufacturers are actually putting desktop cpu's in laptops .. and if that's the case go for Q6700 and overclock it , you will get lower benchmarks currently over the Xtreme , but future applications and games will support multy-core better and you'll get better proccessor

don't forget that by using desktop cpu's in a lappy you will have :
1. very low battery life
2. heavier laptop (since components will not be designed to be light)
3. hotter operation (smaller place)

but you will be able to :
1. enjoy a better system overall since desktop components have better performance/$
2. ability to upgrade components easily.

cheers

 

These are all desktop processors. But the best of the lot is probably the Q6700 (for the quad core), though I think the other two may be pretty close.

 

The quad is the best. The E6850 is also good, with the fastest un-clocked speed and fastest bus, but don't try it with a laptop. And if you're going to spend the money of the extreme you might as well buy two quads

 

Hmmm.. Thanks for the replies.

Now would something like this overheat often, if it is in fact a desktop CPU in a laptop? Should I get one of those laptop coolers? My friend has one he puts under his alienware, its some sort of extra fans contraption thing.

 

Desktop CPUs will absolutely kill the battery life of a laptop. I have no clue how the C90 or high end Sagars deal with the battery usage.

 

With teh quad under full load be prepared for the laptop to burn though your legs or desk or whatever the laptop is on. I have a quad Core in my PC and to keep it cool my case had 5 120mm fans, 1 200mm fan & the Heat sink weighs 790grams. In a laptop I can't imagine you ever havaing that much air flow or surface area to disipate the heat.

Id estimate the cores would be over 70 degrees most of the time and under load I can't see how in a laptop you could stop it going over 100 and casuing it to trottle. Also under load teh CPU is capable of drawing 135watts of power per hour so to translate that a 9cell laptop battery would have 80 - 90 watts. So you would probably be looking at 40 min of battery life and that is not including the power draw of other components.

If you want teh fastest laptop you can get the Quad core is it. But you might aswell build a deaktop and save yourself some money. Beacuse you get no battery life anyway, its probably going to keep overheating and its is going to weigh nearly as much as a desktop anyways. :s

 

So in other words... it's really not worth it to get a crazy good laptop!

I guess I can get a really good desktop and a pretty good laptop instead.

 

I've given up on gaming on my laptop. I will just buid a very high spec desktop. for everything non gaming all current laptops are fine
