i7 and i7 2nd gen.... what is the difference

post #1 of 6
Thread Starter 
I have a q9300 and was waiting for the die shrink on the i7 to 22nm
So I could upgrade... and then then the second year, I get to upgrade again to the newer chipset, and then skip the next two years of the next die shrink...

When is 22nm coming?
Do I have to wait another entire year?

How much faster is an i7 2nd gen than the first i7...

Please help... just post the right articles for me to read or whatever... I feel heart broken. smile.gif

Ivy bridge will be out in 2011, late 2011, just wait it will be well worth it ivy is supposed to be 20 percent faster then sandy. Your quad is still a very capable chip anyways.

Ivy Bridge is 22nm and should be out sometime in 4Q of this year.

As for your other question, the second gen core i3/5/7s are roughly 15% faster than than the first gen, clock for clock, core for core. They also tend to clock higher, of course.

my bad i have a
q9650
I think by late 2011 the dollar will be collapsing frown.gif
i hope i can afford one....

another real quick question... how much faster is a second gen i7 than my q9650?
the only real positive i see is how they render video better... but i like what I have... I think i may buy another motherboard for now and put some better ssd's on a custom controller... i have three ssd in raid 0 now... but i could upgrade just the hard drives now and rest later

9650 vs a 2500k, the 2600k is about $100 more expensive but better in multithreaded apps (8 threads instead of 4).

Looks like 2nd gen is maybe 30-45% faster depending on your usage, though to be fair those aren't tat the same clock speeds (to be double fair the i5s easily go to 4.5, and some people have gotten them to 5.0 on air).
