I've always believed Hyperthreading has not been used in any modern games since the testing with Total War.

However I do see people saying HT has helped their FPS in games like BF3 etc.

Can anyone prove (I dont want speculation here) than HT helps with gaming.

I know the i7 has more cache than the i5 and thats what I always believed to help with the fps difference. But if I am wrong I want to know it.
 
Thats what I always thought. I could understand if the app / game used HT in its coding. But if every game can take use of HT then suddenly I might start specing the i7 in gaming rigs :p
 
If it will work when the extra threads are needed then surely it would be a big help in more modern games like Crysis and BF3 where the threads can be used. Or is the difference so small because its not a physical core mean its not worth it?
 
While he hasn't got any figures he has given proof, or at least near enough proof. Its a better example than your speculation Martini, unless you have any figures?

And what you said is the percentage gain isn't worth the value. But going by what I've read from your 2 posts.

The current value of a i5 on OcUK is £200 when not on a deal
The current value of an i7 on OcUK is £260.

Your saying that the £60 difference is not worth whatever fps difference there is between the 2 CPU's?
 
I would digress by what you mean as normal? I mean I know its a high price but it is still the RRP at OcUK currently :p

I would be interested in seeing Moogleys test results I have to say

But even though Wucked is using a different CPU than the later gens the fact that he got better results from having HT turned on is what interests me :)
 
Thank you for that Wucked :)

@ Martini sure his core for core performance is lower so I understand the HT is getting used then, but whats the difference between that and a modern i7's threads being used in modern games when paired with high end GPU's.
 
We've seen times where the i5 has become "bottlenecked" because of its 4 core limit. An i7 I would hazard a guess to, provided the games do support the multi-threads like Crysis, BF3 etc, would do better in.

Would you disagree with that?
 
Ahhhh ok. Apologies I thought you were getting accross the i7 would be no benefit. And I know it would be no benefit while the i5 was not hitting 100%. But I see now you mean the same thing I mean.

Although thats interesting stuff on Crysis, I thought it did well on PD because it could max out all its cores, though I was surprised the i7 did not do better.
