If you’re not a geek or nerd, you should probably stop reading right now.<\/p>\n

I upgraded my computer to an Intel Core i5 processor last year, and it’s been good. For Christmas I decided to help Derek upgrade his computer, and since he plays games and needs a fast CPU I planned to get him a Core i7. However, after doing some research he found that the Core i5 that I have is better for gaming, and the Core i7 is better for compiling and other tasks that I do a lot of. <\/p>\n

So we swapped; I got the Core i7 and gave him my Core i5.<\/p>\n

The main difference in the Core i5 and the i7 is that hyperthreading is enabled on the i7 and not on the i5. So with 4 physical cores, the i7 can sometimes run up to 8 separate threads. It is interesting to see the Task Manager Performance page, with 8 virtual processors:<\/p>\n

\"8<\/p>\n

Derek learned that for gaming, most programs can’t take advantage of more than 4 cores, so the overhead of hyperthreading actually slows it down. <\/p>\n

The Windows 7 performance rating only moved from 7.4 to 7.5 for CPU, and nothing else changed. And the difference is most likely just from clock speed — the new i7 runs a little faster than the i5 I did have. The performance rating apparently doesn’t use multiple cores, or at least not that many.<\/p>\n

I’ll see over the next few days as I compile and do other processor-intensive programs if there is any noticeable difference.<\/p>\n","protected":false},"excerpt":{"rendered":"
