From the article at Anandtech

At the same switching speed, Intel's 22nm 3D Tri-Gate transistors can run at 75 - % of the operating voltage of Intel's 32nm transistors. This results in lower active power at the same frequency, or the same active power at a higher performance level. Intel claims that the reduction in active power can be more than 50% compared to its 32nm process.

Whatever it is, the TDP is down to 77W. SB 32nm is 95W, and so was Nehalem (LGA1156 45nm), so that looks promising because there was no real TDP improvement from 45 to 32nm, and it's significant from 32 to 22

All this talk of IB is getting me somewhat excited to see how it turns out. Of course I am not going to go out and buy one on release day but, I will be carefully watching OCer's on the webs to see what they have to say about OC'ing these chips.Also, I really don't think that Intel would make chips that aren't overclockable considering that they now offer CPU insurance. They also ARE selling an unlocked multiplier so that is also another indication that they don't ave any intention on "dumping" the overclocking community. I really will not be suprised if I see people pushing their chips beyond 5GHZ. Maybe a 5.5GHZ OC will be somewhat normal. :Big Grin:

FSX Nirvana! :Nerd:Well, we can only cross our fingers and hope, and, yes, I'll be waiting for Ivy... I just need a way to squash my FSX needs right now -.-

Intresting!

1. If voltage is 75%, power is (75%) ^ 2 = 56%
2. Now IB TDP = 77W / 95W SB TDP = 81% of SB TDP, therefore
3. IB Gate Count = 81% / 56% = 145% SB Gate Count <-- That's pretty spectacular!
4. Check calculation: 32 nm / 22 nm = 145%, assuming constant chip size in mm2.

Ya think he read the thread? Lol. Proof that there is terrible, terrible advice on the forums and you have to be careful who you listen to.

No one here, including me of course, knows for a fact how much better IB will be, so don't jump the gun guys. I don't think PCIe 3.0 is gonna have that huge of an impact. It's certainly not going to double your FPS especially with complex addons (more CPU demanding).If that's the case I may very well skip IB altogether and wait for Haswell if IB doesn't overclock at least to 6GHz, which is quite unlikely.Time will tell.Wether someone should wait or not at this point is up to each one. Keep in mind that IB will be released by April, but what about Kepler? That could leave you waiting till the summer

I agree. If it doesn't OC to at least 6, then I'll wait. Maybe until:http://www.zdnet.com...14-or-2015/7065

Well one thing for sure, this thread helped me make up my own mind on how to advise people! I recommend a Sandy Bridge i7 2600K or 2700K, a good ASUS MB, and OC the snot out of it right now.Then when IB comes out, if (and only if) it is worthwhile, swap out just the CPU (plus the MB if it is deemed to be beneficial), for the best IB to come. SB resale demand and value should still be high.Kepler? Don't know, for no one really knows enough about it yet to even speculate intelligently. anyway, the 580GTX is all that anyone needs (and then some) for maximum FSX performance.Fortunately I wisely made the right decision for SB and the 580 GTX over a year ago, so what was the right decision for then, also proves (to me) to still be the best decision for now!It's a no brainer.Kind regards,PS: Why not the i5 2500K? Because certain upcoming software that may be better than most think likes hyperthreading, that's why.

@jahman--the big question in my mind is how heat dissipation is affected by the 3D matrix. I haven't seen any good discussion of how heat conduction pathways from the center of the matrix might affect cooling, operating temps, and thus overclockability. I suspect this is going to be a winner...but we really don't know for sure just yet . (null)

Guys, I want to remind you this thread is about helping Aamir choose the hardware, not an Ivy Bridge discussion thread.Please just keep it about his needs. There are couple of threads on IB (or a new one if you so desire). But I would suggest we all hold off speculating what is going to be or not. It's of no real use. Of course, it's only a suggestion. ^_^

Aamir, only you know how soon you need a proper desktop. You can always wait for something better when it comes to computer hardware.There is nothing stopping you from putting in an Ivy Bridge later if you get a SB now on a mobo with PCIe 3.0 support.If it was a new architecture (haswell) around the corner I would recommend to hold off as its so close and it does not support the same socket.If you were buying a laptop I would recommend to hold off as most if the improvements with Ivy Bridge are more to the benefit of Laptops.Stick with a GTX580 for now.Enjoy your new build whenever it happens

So true... :/Thank you, Mr. moderator...

Kepler? Don't know, for no one really knows enough about it yet to even speculate intelligently

The Kepler roadmap was recently leaked, good stuff there... Might wait. April is the release date, in time for my B'day :D

#####?The dood is on a laptop and "money is no object".

Umm, yeah, I needed it for school? I've never had the need for desktops 'till now. It's no slouch either, SB i7 2.2GHz.. But FSX demands more -.-

We simply don't know enough performance wise as it applies to FSX. I don't think anymore video card above the 580 GTX will enhance FSX (due to its hardwired limitations), faster CPU yes, GPU no

Well, if it's that much more powerfull than Fermi it may allow us to run 4xSGSS with decent performance in clouds.
