Quick CPU question .....

[Boney]

I am looking into buying a laptop and was wondering how much performance difference there was between the two cpus.


An "yonah" single core at 1.66Ghz
and an turion 64 at ........ 1.80 Ghz

Would they be about equal ?

And for the turion - for $100 more i can upgrade to a 2.2Ghz ..... would that be a significant improvement performance wise to justify the upgrade cost?

For the most part Turions are the equivalent of Dothan's at the same clock. Since Yonah does not really improve on Dothan that much I'd say that the 1.8GHz turion will be quite a bit better. Battery life, of course, should be better on Yonah, and this is specially true if the Turion is an ML part rather than a lower-voltage MT.

I have a 2.2 ghz MT turion in my laptop my friend has the 1.8ghz MT turion in his lappy and we switched cpu's for a day. I think mine was slower and he said his was much faster so. I would go with the 2.2ghz > 1.8h=ghz IMHO

i am so confused

Also comparing a turion to a turion is way different than comparing a yonah to a turion.

Clock for clock yonah and turion are pretty equal, so the turion would have slightly better performance in CPU intensive tasks. Depending on the configuration, the yonah will probably get a little better battery life.

The only benchmarks I know of show Core Duo hanging in there with the big boys, i.e. the leading desktop CPUs at the time. Have not seen any benchmarks using the two specific CPUs that you mention, at those clocked speeds. Sorry.

If you need 64-bit computing, or if you intend to upgrade to 64-bit Windows Vista, your choice is easy: the AMD 64-bit CPU, or wait for Core 2 Duo (due August). If battery life is more important to you, then the Core Duo, & a Centrino notebook in particular, should have a marked advantage. One of the reasons Intel did not implement 64-bit extensions on Core Duo was because it would have cost them on battery life.
