Core 2 Duo vs Core i5?

post #1 of 12
Thread Starter 
I went to a friends house and he had the 2011 Core i5 Macbook with Intel 3000M Graphics, and mine is the 2010 Model with the Core 2 Duo and the Geforce 320M. We could both open the exact same amount of heavy applications before seeing some lag. So how much better is the i5 MBP CPU than the Core 2 Duo in the previous generation, because it really doesn't seem so much better.

I think they are comparable because the i5 in the MBP is a dual core as well. I don't see it as being a benefit if your thinking of upgrading.

Other things might have come into play as well, such as how much RAM is on each laptop, and what speeds.

Try doing something that involves encoding and is measured objectively.

You'll see the difference.

The i5 is a hyperthreaded dual core, which means it has 4 threads. That plus the faster architecture of the iX series make the i5 a faster CPU, probably twice as fast overall.

Of course. 4 threads means its 2x as fast

It really isn't THAT much faster. More or less use less energy and is a little faster due to the architecture. Hyperthreading will help with certain programs and such.

Ofc not, upgrade isnt worth it for me. His PC can barely run CSS on that crappy Intel card, but the 320m runs it great. Hell, 3000M even lags on MW2 on lowest possible settings with 620x480.
post #9 of 12
Wasn't the 3000M supposed to be comparable to the 9400m?

If so it's haulin' ass, the 9400m in my late 08 15 inch MBP is amazing

I think you are thinking about the i7's hyperthreading. Hyperthreading on the i7 will not help as much in real life applications because simply put, no normal day to day program will use up to 8 threads.

Hyperthreading on a dual core, however, will scale the cores up to 4 threads, which programs and games can fully utilize.
