My friend has a Core 2 Extreme based computer and was wondering if performance would be gained if upgraded to regular core i7/corei5 (not extreme edition).

There are a lot of variables involved, such as which Core 2 Extreme, which Core i7/i5 you're thinking of using.


The Core i5, probably not.  The Core i7, probably...  but again, it depends.  It depends on which applications, games, and other parts of the system.


Here is a link to Tom's CPU Charts, which gives very clear and specific benchmark information regarding performance differences between current Intel CPU's.

The top-of-the-line Core 2 Extreme is the QX9770. This CPU scores 5005 on PassMark's CPUMark, an excellent measure of CPU "horsepower" which is arguably the best benchmark for comparing the performance of different CPUs.

The top-of-the-line Core i7 Extreme is the 6 core i7-980X. This superb CPU scores 10098 -- more than double the QX9770. But since your friend isn't interesting in the "exteme" i7's, whether or not an upgrade would provide a processing power boost depends on exactly which mode of the Core 2 extremes he has, and which Core i7 he's considering. A Core i7-920 scores 5580, an i7-950 scores 6284, and an i7-965 scores 6786 on PassMark ... so if he has the QX9770 I'd say it's not worth the cost of an upgrade. But if he has one of the lower-performance Core 2 Extremes it may be worthwhile. For example, a Core 2 Extreme QX6800 only scores 3610 on PassMark.

None of the i3's or i5's come close to the Core 2 Extreme performance.

Note that a lower-cost (non-extreme) version of the Core i7 hex-core CPU is expected this fall, which will likely have excellent performance (I'd guess ~7500 - 8000 on PassMark) for ~ $500.

Your friend should simply look up his current CPU and any CPU's he's considering as an upgrade on PassMark and compare them:  http://www.cpubenchmark.net/cpu_list.php

... one  other thought:   The above simply addresses CPU performance.    Don't forget that the overall performance of a system depends on much more than just the CPU  ==> especially if this is a gaming system.    The performance of the graphics processor(s), hard drives, etc. can make a huge difference in the overall performance.    Your friend could be very disappointed if he built a Core i7 hex-core system with the superb 980X, but used a low-cost graphics card.    You have to consider all of the elements when building a high-performance system.

He already has a high end graphic card, so no worries about the other components. As far as the cpu goes he exactly have the Core 2 Extreme X9100 he has the core i7 920 in mind, since it scores quite better than the Core 2 Extreme 9770 the upgrade from 9100 to core i7 920 should yield more than a marginal performance boost

Agree -- the X9100 scores 2280, vs 5579 for an i7 920.

That's a very nice bump in performance.
