i5 vs i7 (1156) w/no HT

post #1 of 13
Thread Starter 
Is there any reviews like this anywhere. I know everyone says if you don't need HT go i5. But I'm just curious if for example, you took an i5 quad and an i7 quad (1156 chips). Put them both at 4ghz and turned HT off on the i7.

Would they bench pretty much the same. Or is the i7 superior in other ways.

I'm asking this because I assume it will be similar to the new 2500 vs 2600. Just trying to get an idea if HT is really the only difference between the two.

If anyone is interested I'm down to turn off HT and run a couple benches vs an i5. Of course mine is 1366 but whatever.

Well, the 1366 chips use a completely different architecture, so that would be an unfair comparison, but I'd also be interested to see how an i7-8xx at 4GHz with HT off compares to an i5-7xx at 4GHz.

Ok yah I just added that in there for the hell of it. But the question still stands. I guess its not as common knowledge as I thought.

I'm sure someone on here will know; it hasn't been very long since this was posted to be honest.

The 1366 with HT off is just a little bit faster then the i5 760. That is mostly due to Better mbs and ram.

The 1366 is the highend socket.. With that comes the better mbs ram etc..

Just like Ivy Bridge will get better stuff then Sandy Bridge.

They are Marketed at 2 different kinds of pc users.

my guess is they would probably be the same (since no one seems to be giving you your i5 vs i7 no ht answer)

I have the 870, and I'm down to do cinebench 11.5 at 4ghz with ht off.
mobo, ram, and such will vary the comparison, but not by much.

Sandy Bridge is the name of the micro architecture.

Ivy Bridge is a die shrink(to 22nm) of Sandy Bridge. They're not two different platforms much in the same way Westmere is just a 32nm die shrink of Nehalem with some cache memory improvements. Its all on the same platform unless Intel changes something.

This. It's likely that at least the first few Ivy Bridge chips will be on the same socket as Sandy Bridge (1155).
