True, but more apps are being multi-threaded these days, even games. Of course each generation's going to be better per single core performance, or they'd end up like AMD. wink.gif

Thought I'd share my small list of Cinebench benchmarks. It's more like a 17.86% loss, not 5.2%.
LEAD Technologies Inc. V1.01

Some people can get their 980X's to 4.5GHz or even higher at 1.4V's. I'm limited on my 3770K overclock to 4.8GHz until it gets de-lidded (if ever). That's with a dedicated 4x120 rad loop with 8 Noctua NF-P12's in push/pull at 7V's and a Maingear Epic T1000 on it with temps not going over 86C during Prime95 Blend. biggrin.gif

Or since people are so fond of car analogies, you're gaining 10% more horse power and 15-20% better MPG every year!

Eh how do you know a 4.2ghz clock 4570k is same as a 5ghz 2500k?

He must be assuming a roughly 20% improvement clock for clock ... that would give you the numbers he is talking about.

It will likely be closer to 15% from IVY to HASWELL, a 15% increase clock for clock would be 4.83ghz.

oops he is talking the old sandy bridge so yes it will posibly be closer to 5.4ghz assuming a 30% increase in performance clock for clock from sandy to haswell

on a low end his 20% is very possible as well smile.gif not a bad improvement

With the sale of my current golden 2500K and motherboard i think stepping up to haswell will be reasonably cheap for the gains.

Which means the Ivy-E 22nm die shrink could easily lead to 2 more cores & more clocks while staying at the same TDP.

The last time Intel Die-shrinked their 130W Enthusiast Platform:

Bloomfield i7-965 , 45nm, 3.2 Ghz Quad Core 130W, 263 mm^2, LGA1366 $999(Tock)

Gulftown i7-980X , 32nm,3.33Ghz Hexcore 130W, 240 mm^2, LGA 1366 $999(Tick)

This Time:
Sandy Bridge-E , 32nm , i7-3960X 3.4Ghz Hexcore, 435 mm^2, 130W LGA2011 $999(Tock)

Ivy Bridge-E, 22nm, i7-49XXX 130W? LGA 2011(Tick):

See a trend? I see that Intel have plenty of room to add at least two cores to the IB-E die while still reducing die size compared to SB-E, the TDP will likely stay the same while the IB-E chip get a higher stock clock than its SB-E counter parts.

Because Intel's Enthusiast lineup don't care/focus on about IGP performance or power consumption improvement, it is highly likely that Intel add cores again on a Enthusiast level die shrink while also adding clocks, the price & TDP though will likely stay the same.

Technically speaking you are spot on with the above, but with the $2k XEON E5-2687W being a 8core 3.1ghz I just can't see a $600 overclockable equivalent (or near enough) appearing in 6 months time. I would love to be wrong however biggrin.gif

I am fine with my two i7-3770k and quite happy I sold my 2500k few weeks ago.

Hi, thanks for replying to me. I may wait for Kaveri and see it's performance too, before I buy something.

Did any one of you crunch any numbers?

Lame was about a Haswell 5% increase
Blender was about a Haswell 7% increase
Winzip was about a Haswell 7% increase
Luxmark was about a Haswell 5% increase

You guys calling this a 10% or 15% IPC increase need to step back and do some math. When you crunch the numbers this thing is a turd. If they really did remove x87 and translate it to SSE now, Skyrim and Super Pi are going to end up like that other company that doesn't do x87 and has to translate.

If this is the best Intel can do with a tock they either stopped caring about us enthusiasts or they've ran out of room to grow.

Although the lack of Haswell-E makes a lot more sense now. It might clock better but a Haswell die is larger than an Ivy die, so they're going to make more money selling Ivy Bridge E than they would Haswell-E, and the performance isn't anything above meh.

I wouldn't be surprised if Haswell-E ended up cancelled, but Intel is probably going to want to slap $1000 price tags on reject Xeons so it's probably still on.

Because IB is about 10% faster than SB, and haswell is about 10% faster than IB.

So 4.2 + 21% = 5.08

This guy gets it =)

And like I said earlier you're getting a decent performance boost, along with using far less power.
