MacBookPro: 2.8 GHz Core Duo VS I5 2.53 GHz

[fabbione]

Hi All,

I've a very urgent question for any of you!!
I'm going to buy a new MacBookPro and I discovered the new I5/I7 processors.
I've found on the net some benchmarks of the new I7 (2.66 GHz) versus the 2.8 Core Duo: it seems that the gain in terms of speed is about 50%...
(MacBook Pro 15-inch Core i7 Benchmarked: It's So Fast - Macbook pro core i7 benchmark - Gizmodo)

But what about I5 (2.53 GHz) vs 2.8 GHz dual core?

Bye

Bare Feats should have this info for you shortly, but I wouldn't expect huge gains.

The Core iX chips' appeal isn't that they are hugely faster, its that they are more efficient. There's a difference. Yes, you'd generally some some speed pickup, but not "blow the doors off" difference. It's more about the overall smoothness of operations rather than raw speed.

The primary place you'll see any difference at this point in time will be video encoding, but only with apps that have been optimized for multiple cores.

You'll not notice any difference in your typical everyday tasks, i.e. mail, browsing, listening to music, watching a video, etc.
