core 2 duo 1.73 vs core duo 2 ghz?

I am looking for a spare computer and wanted to just pick one up at Compusa. Initially I was just going to get the dv6426us because it's just $650, but then I looked a bit more and saw the dv6345us which is $850.

What is better a core 2 duo with lower ghz or a core duo with higher??

If the core 2 duo is better is it worth the $200?

Usually I like to go all out, but now I'm just looking for a spare computer, but still would like to be as good as possible for as little as possible...

Thanks!!!

 

Well... real world performance they'll perform pretty much the same. They both have 533mhz FSB, 2mb l2 cache. The Core 2 Duo is newer and more efficient but the higher clock speed of the Core Duo makes up for the slightly less efficiency. Uhh yeah, I'm thinkin performance would be about the same to tell you the truth. I'll be Da***d if you notice the difference between the two.

 

A higher number is better. Ghz is (basically) a measure of how fast a computer can process data. For instance a 1 Ghz machine is 1 Ghz slower than a 2 Ghz machine.

 

lol. sort of...

ghz doesn't really matter any more. the architecture is what counts. architectures are labeled: pentium 4, core duo, athlon 64, core 2 duo, that sort of thing.

a core 2 duo with a slightly lower clockspeed will match a core duo with slightly higher clock speed. pretty simple. at equal clock speeds, a core 2 duo gets like 15% extra performance at 15% reduced power draw, or something like that. maybe 10%. still, thats enough to basically equalize performance between the two, with the added benefit of less power consumption of the core 2 duo.

you could also run a 64 bit operating system with the core 2 duo (which would only be a benefit if you chose to do that)

so is that worth $200? maybe, if you care a lot about power consumption (battery life) or if you are thinking about upgrading to a 64 bit operating system or if you want to use 4 GB of ram in the future.
