I don't think it is a placeholder price. Placeholder prices are usually extremely high. This looks plausible here.

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.

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...

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).

That graph is wrong, at least for client workloads.

http://ixbtlabs.com/articles3/cpu/sandybridge-core-vs-lynnfield-p1.html

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.

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?

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.

FC is flip chip. LGA is land grid array. The 14c I have no idea on, but it might be a generational code of some kind or node. IE, search for FC-LGA12C and you'll find a bunch of IB and HW parts.

It's not wrong just using different benchmarks, for example Tom's Hardware 2015 CPU charts gives for Total Time:

I7-975 EE (3.33/3.6) 1854
I7-2600K (3.4/3.8) 1678 10.6%, about 8.2% clock adjusted
I7-2700K (3.5/3.9) 1638
I7-3770K (3.5/3.9) 1523 7.6%
I7-4770K (3.5/3.9) 1385 10%

A) I never claimed Haswell has greater gains - check my post.
B) Every 'graph' is wrong in a sense since there is no industry standard workload. Which also means every graph is right, according to the workload used.

The simple point that I was making is that there are two types of IPC with an SMT core. In Intel's case, with HT on and with HT off.

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-order-pricing-for-intel-haswell-e-desktop-processors-revealed/

is that the normal turn around?

If Computex has manufacturers showing off new motherboards - is there something that could leak if Intel doesn't announce more info at Computex? (Alpine Ridge for example?). Would the OEMs and motherboard makers want to have Skylake CPUs to demo, or would Intel force them to wait?
 
Why are we discussing broadwell in skylake, thread?

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.

DDR3L and LPDDR3....not plain DDR3. Not official though.
 
Apparently Apple skipped Broadwell-H.

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.

There were rumours of quad-core Skylake with Iris Pro 'GT4e' graphics launching as soon as Q4 or early 2016. Perhaps that's when the big refresh will happen.

In Intels current graphics driver a new GPU naming scheme appeared and I'm pretty sure it belongs to Skylake.
