***Official Intel Haswell Thread***

Yeah, 4.5-4.6 on Haswell will match a 5GHz SB and 4.8 will def pass it, but it would be so close that is it really worth the effort?..

I way i see it so far is if you have a good clocking SB or IB CPU that can do 4.8g there is no advantage getting a Haswell that will only do 4.4 to 4.5g

The added on board voltage regulation and higher TDP kind of tells you its a hotter running chip, unless you get a good chip that will also do 4.8g then you will see a slight improvement. the thing is on every new release from intel with the integration on die of M/B features they will get hotter and slower for sure.

there will be chips that break the average with good overclocking ability but it will be more of a rare thing than common place. these CPU's by there nature are designed for integrated systems run at stock and i suspect 99% of sales for haswell will end up running stock using the onboard GFX.

Its a shame that the true enthusiast socket 2011 is showing its age as this would now have to be the socket of choice for true overclocking. its a shame intel duped everyone into believing haswell was the next great overclocker, as it seems pre production CPU's touted by intel led everyone to believe the hype surrounding haswell as good clocking CPU's
 
Didn't Intel state that Ivybridge is 10% faster than Sandybridge, and now Haswell is 10% faster than Ivybridge, does this reflect the various benchmarks in reviews...? I haven't really had a good look at reviews yet.

So a 4.4GHz Ivybridge = 4.8GHz Sandybridge, 4.4GHz Haswell = 4.8GHz Ivybridge.

It's funny how spoilt sandybridge made us, most Haswells will do 20%+ overclock and we're all abusing it for being rubbish.

This is true, we all want more from each release


So a 4.4GHz Ivybridge = 4.8GHz Sandybridge, 4.4GHz Haswell = 4.8GHz Ivybridge.

Iam not sure it quite scales like that, but its not far off! thing is a 4.4ghz haswell seems like its going to have to be a good chip to be stable at 4.4ghz

heat is the issue, and voltage to get stabilty at 4.4ghz could be high, which inturn means more heat, and yea summers coming we hope!

So does that make a 4ghz Haswell as quick as a 4.8ghz Sandybridge?

Not really, the 10% speed improvement is quoted for stock speeds under ideal conditions taking turbo boost etc into account. Not quite so simple once you start overclocking as you dont get a perfect scaling of performance gain with increased frequency. From reviews I've seen it looks like you need around 4.2-4.4 on haswell to match 4.8 on SB.
 
There is of course the +10% heat they seem to have introduced :P

Not going to stop me jumping on it when boards are available that I want. my i7 950 is abysmal for overclocking. The extra power Haswell will give should be nice for my rendering, even if x79 is better, Im not sure the extra cost is worth it. Also, haswell boards are sexy.
 
ivybridge is roughly 200mhz quicker than sb and haswell if roughly 200mhz quicker than ib

seems that's about right to me

so 4.6ghz haswell = 4.8ghz ivy

and 4.6ghz haswell = 5ghz sandy

4.6ghz on ivy = 4.8ghz sandy

Buckster mate we got 2 gaming pcs that take from socket over 1100w easy.
Who cares about power drawn when you are buying almost 300f worth of cpu anyway ??

And no 4.4 Is not enough to pass 5ghz sandy it cant even match it....
In cinebench single core 4.8ghz haswell pulls out 2.10 Where Sandy at 5ghz pulls 2.02
my 2500k@5ghz

So by looks of it 4.6-4.7ghz haswell will be 1:1 with 5ghz sandy in singe core games. Not to mention 4770k got bit more internal cache if i am not wrong.


edit. Forgot 4770k link :P

^^ all I'm saying is if you are building a system now - Haswell is a no-brainer

as good performance as previous (give or take) - at much lower power :)

in this country - if you had 2 PCs like yours at 5.0 gig - and they were on under load for 15 hours a day- you'd use up about £145 a year less in electricity :)

thats quite a saving - not enough to upgrade for it - but its impressive none ht less

This sounds about right. I think for anyone with even an average clocking Sandy Bridge CPU Haswell isn't worth the upgrade.
