If it can hit stock 4.2 then I doubt its a suicide run at 4.8 but it might involve custom water to get 4.8. If it does 4.8 on air or aio water I'm getting this on release.
We dont know at what voltage that 4.8GHz was obtained, could be a suicide run so lets wait and see.
"fc-lga14c"
Well, most tests are done with HT on. This graph isn't going to match what is essential an effective 'IPC' per core w/SMT that you'll find in lots of review sites.
Most users aren't looking for SPECint_rate scores for single core w/o HT and single core w/HT type results - so PC enthusiast sites don't run those kind of tests (at least I haven't seen that lately).
Yeah, what is that? A search for it also turns up Broadwell at NCIX.
I'm thinking the 14 must be nanometers, and not anything to do with the chipset.
That graph is wrong, at least for client workloads.

With Nehalem the tests are all over the place. It gets a lot in memory bandwidth sensitive applications sure, but that's much less common in client workloads than in server. In those that represent mostly core enhancements, the gains are often only 5%. In RWT some reported that in code that are core-bound and show architectural differences, it can be close to nothing and even slower.
Sandy Bridge was more consistent, and greater overall. The bigger jumps are not from Wolfdale to Lynnfield(which in the Toms test has a 2% disadvantage due to clocks)/Bloomfield but to Sandy Bridge.

Same on here, although with 4 cores/HT off/Turbo off/Same clocks: http://www.anandtech.com/show/8426/...view-core-i7-5960x-i7-5930k-i7-5820k-tested/2
Even if you normalize for clocks, the biggest gain is from Nehalem to Sandy Bridge, not Ivy Bridge to Haswell.

Still saying Haswell has greater gains?

Already listed and launching in August? Something is weird here.
Haswell-E prices leaked/had pre-order prices around mid-July. Released late August, reviews out around then.. http://www.zdnet.com/article/pre-ord...sors-revealed/
That article is from last year. Haswell-E is already released.
He knows that. He was asking if the timing of pre-order/release/review would be similar.
It is not under water but with a much more extreme cooling solution, he could had displayed 6GHz as wel,l but i guess that it had to stay realistic.
The "leaker" didnt pay attention to some details, expressely that 14nm require higher voltage than 22nm, and that on air 1.419V is not enough to sustain 5GHz unless the 14nm process has a perfect voltage/frequency curve up to 5.0, wich is dubbious since the 22nm has terrible caracteristic above 4.0 with the 4770K requiring 50% more power to get to 4.4 from 4.0...
All this rather look like an orchestrated marketing campaign if not a damage control campaign...
What about the memory controller on Skylake, I hear a while ago that Skylake will have a memory controller that will let it support DDR3 (not DDR3L) and DDR4, is that actually true? or it is confirmed by Intel?
PS. i'm looking for that article.
Oh I see.DDR3L and LPDDR3....not plain DDR3. Not official though.
Given that the necessary Broadwell chips are not yet available, the new 15-inch MacBook Pro and 27-inch iMac still have Intel's fourth-generation Haswell processors. Based on the average product cycle for the MacBook Pro and iMac, Apple may choose to skip Broadwell processors and use next-generation Skylake processors for the next versions of the notebook and all-in-one desktop computer respectively. Those models are unlikely to be released until late 2015 at the earliest.
In Intels current graphics driver a new GPU naming scheme appeared and I'm pretty sure it belongs to Skylake.
Intel® Genuine Intel® CPU 0000.
Leak: Skylake-Y, Skylake-U, Skylake-H, Skylake-S Models and Launch Date
http://benchlife.info/intel-skylake-replace-broadwell-start-from-q3-05202015
Skylake-Y, Skylake-U, Skylake-H and Skylake-S will arrive as soon as September 2015.
And now we know why Apple skipped Broadwell-H.
And ASUS's statement about Skylake + Windows 10 notebooks by Q3 makes sense.
That's quite a bit sooner than I was expecting, especially Skylake-H.
