Intel T6500 vs P7350

Hello,

Since my laptop of several years has finally decided to call it quits (I suspect motherboard failure or some sort of power failure), I've decided to start shopping for a new one.

One set of laptops in particular have caught my eye - the Sony Vaio NW series. They have two models available from the Sony site, the NW 180J and the NW 130J. The 180 is about $150 more expensive, with a few differences: it has a blu ray player (which I won't use), a slightly larger hard drive (I have several external ones already, space isn't an issue), and a different CPU.

The 180 has an Intel P7350, which has a clock speed of 2.0GHz, a front side bus speed of 1066 MHz, and a L2 cache size of 3MB. The 130 has an Intel T6500, which has a clock speed of 2.1GHz, a front side bus speed of 800 MHz, and a L2 cache size of 2MB.

Both are dual core with a 64-bit instruction set.

I intend to use the laptop to play some games (though I'm not a hardcore PC gamer). I will also be doing a lot of programming on it, so being able to handle an IDE plus a browser is important, primarily IntelliJ IDEA, which can be pretty intense on resources sometimes.

I am curious to know how big a difference a slightly slower clock speed but faster bus speed and larger cache will make, and if it's worth the extra money just for that difference. Also, as a purely aesthetic note, the 180 only comes in silver, which I don't like that much.

As a point of reference, here are the Intel pages for the two processors:

T6500 : http://ark.intel.com/Product.aspx?id=39311&code=t6500


Thanks for your help.

edit:
Here is a cnet side-by-side comparison of the two laptops, just for reference:

Quick bump.

Hate to be annoying like that, but I'm hoping to get a response before I go home, since I won't, well, have a computer at home. :( 

Thanks again. :)

I'd go with the one with a clock speed of 2.0Ghz since a drop of 100Mhz isn't going to be enough to have adverse consequences because you do have a higher FSB speed and more cache.

I'd go with the 180 since:

1. it comes with a laptop blu ray player which already makes the difference in price

2. I'm pretty sure the P7350 is faster since it has more cache and a faster FSB which probably means faster RAM (the .1ghz shouldn't make a difference since it has the cache advantage)

3. Since the P7350 is based off a 45nm architecture, it probably consumes less power (versus the T6500 65nm)

4. Larger harddrive (another advance in the price)

5. Since it comes with a blu ray drive, I'm going to assume it has a better integrated/discrete graphics solution and therefore will probably play games better

didn't realize your comparison link... the 180 should still play games better though -- since it has a better CPU

I'd go with the P7350 for one simple reason - all T series CPUs have a 35W TDP, and all P series have a 25W. In a laptop, this is a significant difference.

+1 for the P7350...As others have pointed out, the clock difference is easily compensated by the extra cache and FSB...And like cjl pointed out, has a lower TDP too...
