After reading various posts and websites I am a bit confused.

1) Is the i5 a crap version of the i7?

2) Is Intel going to phase out the i7 once the i5 is released?

3) Is the i7 better at overclocking than the i5? I have seen posts
where people have been able to overclock the i7 extreme to between
4.5 and 5.5 Ghz with water cooling. From what I have read the i5
will be coming out in 2.66GHz, 2.80GHz, and 2.93GHz versions and
Intel say you should be able to overclock the 2.93 version to 3.4
which isn’t much really.

4) Can you get Sata 3 motherboards for the i7?

5) Should I get an i7 extreme before they get phased out?


Here are some of the comments I have seen

“A Core7 IS the Ferrari of CPUs, A Core5 is a BMW”


“Dam, I was going to get a i7 920 in like 2 weeks, does this mean I
have to wait until September to get a worse CPU for more money?
Or should I just buy a 920, and hope it doesn't break?”

“I bet that the i5 will not overclock as well as the i7, due to
its rumored higher BCLK of 250 MHz, hope I'm wrong”

“The added knowledge that the cheap i5 boards get Sata3. I
guess early adapters must feel very angry now with their expensive i7
motherboards. And why do we need another socket for the i5”

“Spec wise the i5 look virtually identical to i7. They have a
tad lower QPI I believe though, and perhaps less instruction sets? Is
the motherboard going to be the main distinguishing factor b/t the
two?”

“I'm guessing they are going to put clock controls on these
chips to limit how high they can go? Also they seem to be more or
less the same price as the i'7's! same price for a lesser chip?”

“You'll find it MUCH MORE DIFFICULT to clock-double an
integrated northbridge and CPU. Either the Northbridge won’t
handle it, or it will send your PCI/PCIe slots out of whack.”

No, its not a crap version, its just the consumer version -> Ci7 is essentially server grade hardware.

ad 2)
No, Lynnfield is marketed under the same Ci7 brand as bloomfield. They only thing that might happen is that the lower end Ci7 bloomfields get phased out. But thats no problem at all, cause UP (Uni Processor) Xeons just fit in every S1336 Mobo

ad 3)
knoone knows, but first clocking test showed that lynnfield can reach the same bclcks as Ci7. With the higher turbo multis you maybe can clock it even higher.

ad 4)
Yes but only with 3rd party controllers, Gigabyte already showed its P55 with sata3.

ad 5)
forget the extreme, its only worth it if you for LN2/Cascade. For air a 920 is more then enough, and a 940/950 for water (but a 920 is also enough for water).
