SB vs. IB

Cythx · 18 Apr 2012 at 13:33

I'm in the middle of building a computer and have all my parts besides the CPU, which I'm now carefully considering.

Since this is a gaming PC and I do not use many productivity apps, I will not really benefit from HyperThreading, so an i7 is a waste for me, and I will be going with an i5.

The choice is now narrowed down to an i5 3570k or i5 2500k.

From what I hear, the i5 3750k won't be that much more expensive, maybe £10-15 or so. However, if the 3750 does not come out within 10 days, I will not be able to use my 10% off voucher. So it could be £30-35 more expensive.

I will almost certainly buy an i5 3570k if it comes out within the next 10 days, how likely is it that it will come out within 10 days?

If it does not come out within the next 10 days, and I end up needing £30 more for it. Is it worth it? From what I hear, I will be paying the extra £30 for: lower power consumption, better iGPU and better performance per clock but a possibly lower max overclock which makes it difficult to gauge which would be better when I finish OC'ing them.

Is there anything I am missing or are the above 3 factors the only benefits I will see from IB? FYI I won't be using QuickSync, which is improved, so it's not really a benefit to me.

EDIT: Say the IB can't overclock as far as SB. Will a 4.4 Ghz i5 IB be less likely to bottleneck me than a 4.7 Ghz i5 SB in the future, when I upgrade to 680 SLI or other high end GPU setups? Or are they really the same in terms of which will last the longest without bottlenecking future GPUs.

Andrew Moore I think it is from OCUK, said Intel have mentioned nothing about the early release. I think the release date with be 28-29th.

The ivy bridge CPUs (including the i5 3570K) are expected to arrive on Monday, so you should be able to use your voucher with this new CPU.

Also, on launch day you can expect a wave of in-depth reviews (including a lot of focus on overclocking) so you should be able to make your decision then with the facts in your hand.

Some people are saying it'll be a week earlier than others, what reliable sources did people have to assume it'll be out a week earlier than initially thought?

The new info was from CNET and their unnamed sources.

TomsHW also wrote an article announcing the release date being move earlier by a week. If these are true, I'll deff. be buying a 3570k.

OCUK staff have said they received an email from Intel saying they are not releasing early

I thought they said they didnt get a response either way?

Will an overclocked 3570k last me longer than an overclocked 2500k in terms of bottlenecking multi-monitor multi-GPU setups?

Most likely yes, but we can't really confirm this until we see a good spread of overclocking results on release silicon.

I'm sure a OCUK staff member confirmed that Intel emailed them to say that they had made no announcement regarding early NDA lifting. However, if that is how they worded it, it isn't a denial, merely a statement that they haven't officially said anything...

No, I definitely read that they had a response from them. I tried to find the post but couldn't amongst the large amount of IB threads.

Just get a sandy bridge chip and overclock it:

1. It's cheaper.
2. You can order them now.
3. At a good overclock you really aren't gonna see a difference between SB and IB. Especially if SB clocks better as has been shown in early reviews.

Here is the thread in question and here is what it said exactly:

Andrew Moore said:
Ive had an email from Intel confirming that NOTHING has been said about an early release or at least nothing confirmed. Sorry guys!

So basically he is saying that Intel are saying nothing - so certainly not a denial.

Cythx · 18 Apr 2012 at 21:45

2. Is invalid, I won't be using the PC for at least 2 weeks anyway.

1 is true, but would the SB honestly last longer in terms of bottlenecking performance on multi-monitor/multi-gpu setups?

Andrew Moore · 18 Apr 2012 at 21:46

Intel were in for a meeting today, no early release on the product. Potentially reviews, that is it.

I would not recommend this, firstly points 1 and 3 are just assumptions. Just wait a week or so more and then choose, not point rushing into buying something and then regreting it.

1 is hardly an assumption. I'll buy you an Ivybridge processor if it's cheaper than it's sandy bridge equivalent.

Can't say fairer than that. Cheers for setting us straight

Good to hear about the possibility of early reviews though, I for one am looking forward to seeing how the i5 3570K overclocks.

The estimated price between the 2 chips is £10-15 its not like its going to be a deal breaker....
