core duo vs specific core 2 duo

I know there are plenty of core duo vs. core 2 duo comparisons on the web, but most seem to compare the high end processors (2MB cache vs. 4MB cache). I am deciding better a Intel® Core™ Duo Processor T2250 (1.73GHz) notebook and a $100 more expensive Intel® Core™ 2 Duo Processor T5500 (1.66GHz) notebook. Both have 2MB cache. I was wondering if there is a big performance or other gain with the more expensive Core 2 Duo (ie should I spend the extra $100).
Thanks for your help.

 

The performance should be about the same...the only real difference between the two processors is that Core 2 is 64bit (which you may or may not care about) and that it might work a little faster when encoding/decoding media like HDTV, videos, and large music files. Worth $100 extra? Only if you need the 64bit.

 

The main difference is that they use different cores. Core 2 Duo is based on Merom, which is 64-bit, and in processor intensive applications, is roughly 10% faster than Core Duo. The T5500 has a slightly larger FSB of 667 MHz, but the extra clockspeed of the Core Duo helps it gain back some performance. They should perform similarly.

64-bit is something that isn't really available in the consumer program market, and it will take a few years to become the normal. Persoanlly, I wouldn't pay an extra $100, but thats just me. Someone else may see a $100 as a resonable price.

 

In terms of performance, the nominally slower T5500 might be slightly faster on account of the faster FSB (667MHz against 533MHz) and the internal improvements, but you would need a stopwatch to see the difference.

However, unless you need the 64bit capability of the C2D I would keep the $100 towards more RAM and/or a faster HDD which will give a noticeable improvement in performance when you want your computer to step up a gear.

The extra $100 isn't worth it, unless you absolutely have to have 64-bit capability. Any performance increase is negligible.

 

The difference will hardly be none, considering most versions of Vista are 32 bit.

 

Thanks!
I don't need 64bit right now, so I'll keep the $100 can go with the core duo.

 

Right now, I have a Core Duo T2400 1.83ghz in my laptop and it is enough for my needs. I can rip, burn, watch a DVD, and run several apps at the same time with no slowdown at all. Its great, the first gen core duo cpu's are still good, of course if you can opt for the core 2 duo's.

core 2 duo t5500 out performs the core duo t2400 by about 13% to 48%. depending on what application u are running. just a little stat for jo noggin

 

Core 2 duo is only worth the price jump on the desktop version, which has a considerable leap in performance from its counterpart.

 

48%!!!!! where did you find that stat?
