Sandy or Ivy

With all the deals and things on sandy bridge, I was really considering updating my amd cpu/motherboard to intel. I was just wondering if it would be a bad idea to jump onto the sandy bridge bandwagon when ivy bridge is so close? I know people have thrown around estimates of a15-20% performance increase and to me that sounds good in theory, but will you see much of it in practice? ( I have a 6990 and I like to throw settings as high as they will go, until performance suffers noticeably.)
 
If you'll be upgrading to a top of the line dual GPU from either nVidia or AMD's next generation cards before upgrading your processor from SB and don't want to be bottlenecked by PCIe 2.0, you should wait for Ivy.

Other than that, a 2500K (OCed) should be sufficient for the next 2-3 years
 
I would personally like to hold on to the 6990 for a bit, so unless the new dual gpus (or high end single gpus) are priced similarly or better and trash previous benchmarks I think I will hold on to it for a while.
 
wait for ivy bridge in the first half of 2012.
 
Most z68 boards will adapt to pcie 3 with a BIOS upgrade. The current sdb chips are going to be viable for many years to come. We just barely go to where code 2 duo and quad are just getting slow

You can wait until ivy but I can almost bet that they are going to be no more than 7-10% more powerdul.a die shrink isn't what makes them faster, albeit cooler and less power hungry. The real power gains are going to come from.more cores smaller process, and software engineered to use that many cores.
 
Exactly. Their is no reason Sandy wont be good enough for quite some time... Ivy is just the next stepping stone... Just like Thuban to Bulldozer... oh wait....

Which CPU do you currently have?

Do you know that other people have thrown around estimates closer to 5%?
 
i have went from 990x to 2600k, to now the 3960x, i must say i like the 2600k because of 5ghz quietly, yes the 3960 will also but alot more cooling needed hence noise, both 1155 and 2011 will support ivy, so really just if u want a 6 core hog or not, im thinking going to 2700k, i like the small chip less heat same ghz oc can be achieved, less wattage less cooling needed less noise
 
I don't understand what all this pining for IVB is about. It's just a die shrink of SDB? This isn't a tick, it's a tock. It's not a Core to Nehalem, or a Westmere to Sandy Bridge.

So if we're going 3D 22nm, we're going to see higher clocks at given TDPs, which is irrelevant to anyone even mildly overclocking SDB anyway, unless you're counting your power bill pennies.

Assuming equal clocks, and ever so slight architecture tweaks, what people seem to be saying is: Wait 4 or 5 months so you can buy a die shrink with single digit IPC increases.

What am I missing? Is there some leaked architecture information I've completely passed over?
 
Current 3900s have no future imo. They are going to release something better later, I think that the 2700s are a better choice.
 
ivy bridge will fit 1155, ivy bridge-e will fit 2011, its just same as sandy 4 core smaller die 6 core bigger die remake of 1156 and 1366, downfall to sandy -e is its very hott 130 watt, takes more cooling to achieve high clocks versus the sayyyy 2600k on the 1155 95 watt, both can and mine both has ran 5ghz, however the 2600k much cooler

I mostly heard the generic 10-20% increase statement. I have hear much lower and higher estimates though, none of which I really choose to believe.



It seems that ivy is not a major step, thus I will just go to microcenter tomorrow and get my computer sandy.
 
We don't even know what ivy is capable of.

I heard it's 10% better stock, and less then 5% better when oc. I have heard that occing still has a similar threshold, what is true...nobody knows.. Just ask yourself is it worth the wait?

Yeah, Intel has said 20% but that is considering performance increases with the integrated graphics also. They haven't said anything (publicly) about clock for clock without graphics being considered but many think it will be single digits like usual.

Even if that's true, Sandy Bridge CPUs won't just magically grow a PCI-E 3 controller. You'll need an Ivy Bridge chip for PCI-E 3 support at the very least.

You'll easily double your processing power :D
 
I just picked up an i5 after reading this thread. Although I wish I'd done so months ago =/

thanks!

Which ones won't? I'm thinking of an ASUS, but these days it seems even their cheapest z68 at $120 is good for overclocking. Will it be able to handle pcie3?

PCIE 3.0 support and chipset with native USB 3.0. That's enough for me to wait those 5 months.
 
There are 2 z68 boards out now B3 (old ones) and (G3). G3 supports pic-e 3.0. So look for one of those, then should you decide to get an ivy you will be pic-e 3.0 ready.

Are they going to continue making new processors for the 1155 platform?
