How much faster?

[IBMorBust]

Hey, what, precisely, is the speed difference between the following two processor chipsets?:

Intel® Core™ 2 Duo processor T8100 (2.1GHz 800MHz 3MBL2)

versus


Intel® Pentium® Dual Core T2370 processor (1.6GHz 533MHz 1MBL2)

In other words, how much faster, really, is the first?

I'm not using any intensive programs. Just the usual suspects.

Both are new systems, and both will have 1GB RAM and will be loaded with XP rather than Vista.

Is the 8100 10% faster, 20%, 30%...?

Sorry for what may be a naive question in advance.


Thanks a million.

I can't provide de exact % but the first one is way too much faster in every aspect. faster clock, front side bus and even the cache which is 3mb.

i know it looked weird... you have this in the T4x forum and the T6x.... continue there since that's where it should be.

(unless you are talking about desktop CPUs? Which machine are you talking about because you can't upgrade your 533mhz FSB T60 to a 800mhz one, you can only use the 533mhz one also)

Aside from the obvious difference in raw clock speed, the core 2duo is a more efficient processor but the big difference is the level 2 cache - this is huge and will have a big impact.
The fsb speed difference, not as great.
A conservative estimate would be at least >25%

Biggest factor is probably the cost difference between the 2 notebooks.

I think that is impossible to answer, without knowing what you actually do with the machine. I used to tell people that if they just did email, word processing, etc, they could use any processor and not notice the difference, unless they measured the startup time, which still depends more on the disk speed. The web pages have become such machine hogs, with all the advertising content, so the dual core CPU is really a help. One processor can be tied up, and you still have another, but there is no good built-in mechanism for farming processes out to CPUs, so one can be swamped and the other idle. I still think that if you do basic tasks (no big photo or movie editing, full-motion games, big program compiles, etc) The difference will be nminimal.

Thanks for the responses everyone. I appreciate the patience.

This guys claims 10%:

This seems a little confusing to me.
