They wanted to get new desktop Iris Pro models out, both R and the new unlocked LGA C models. The Skylake version with 4+4e probally isn't ready yet.
I'm actually kind of surprised they aren't skipping Broadwell for the desktop entirely with the Skylake launch being to close. But I guess they can get the desktop parts to system builders who were already using Broadwell compatible motherboards and now they can advertise them as having the newest generation Intel processor.
Not necessarily. "95W" is a "standard" TDP class / category. Haswell and Ivy Bridge were initially "95W" too.
You're correct that ivy bridge had 95w placeholder TDP( meaning 95W class). But this looks like a final TDP, not merely a placeholder. We have the exact specs for each sku.
I'm confident it will be truly 95.
If that's true, and the final characterized TDP of SKL desktop K CPUs is 95W, then what does that mean for the 14nm process? Why has TDP gone UP, from Ivy to Haswell, now to SKL?

What it means is that the power curve of 14nm was optimized for low-power parts, and 14nm is less efficient at high frequencies. We really, really need new node processes optimized for high performance, but we aren't getting them.
I thought that the particular hit to the voltage / performance curve was said to be a "one time thing", upon the adoption of FinFET. Now, we're seeing it happen with every shrink?

The good part is that Intel's 14nm could potentially be beaten by TSMC's 16nm FinFET, which will have a dedicated high performance node. The same is true if Global Foundries makes a high performance dedicated version of Samsung 14nm FF.
We haven't "seen" anything yet. Everything being discussed here is just speculation on rumors.
.
On LGA 1366 validation time difference between Xeons and the consumer Bloomfield was only one quarter.
Examples:
i7-920 launched Q4 2008 --> http://ark.intel.com/products/37147/Intel-Core-i7-920-Processor-8M-Cache-2_66-GHz-4_80-GTs-Intel-QPI
Xeon X5550 launched Q1 2009--> http://ark.intel.com/products/37106/Intel-Xeon-Processor-X5550-8M-Cache-2_66-GHz-6_40-GTs-Intel-QPI
Eh, no. The drive currents aren't even close to make that happen. You'll continue to see sub-3GHz (max) stuff from the foundries while Intel will still be pushing >4GHz stuff from their node.
That was a theory on this forum, but new evidence suggests 14nm doesn't clock as high as 22nm. Even at the same 65W tdp, Broadwell Iris Pro has a slightly lower turbo than Haswell Iris pro. Same is true for SKL vs DC.
Those are the same die. Current HEDT is using a different die than mainstream DT.
Current Design breakdown is roughly:
Ultra Mobile
Mobile/Desktop
Server/HEDT
Old 920 era breakdown was:
Mobile
Desktop/1-2P Server
4P Server
When they went to fully integrated desktop parts (ie on board PCIe), HEDT/1-2P Server had to merge in with 4P Server functionality wise.

IIRC Intel has varying 14nm nodes for low to higher power (besides TDP isn't a good metric for determing actual power consumption) while TSMC and Samsung only have one version for everything. I think its to show that the K parts have a higher threshold for overclocking which these parts seem to have.What it means is that the power curve of 14nm was optimized for low-power parts, and 14nm is less efficient at high frequencies.

The same is true if Global Foundries makes a high performance dedicated version of Samsung 14nm FF. Intel may still have an advantage in mobile trash that they have to give away for free, but they're going to be facing hard competition from ARM in that arena. Try as they might, they've been unable to break into smartphones with anything but a handful of marketing demos.
The numbers of this graph is certainly NOT Cinebench R15 and certainly NOT ST.
It is Cinebench R11.5 MT.
And in order to show that, they dropped max turbo clocks by 200Mhz compared to DC.I think its to show that the K parts have a higher threshold for overclocking which these parts seem to have.
Exactly. In the new 14nm era, less is more.And in order to show that, they dropped max turbo clocks by 200Mhz compared to DC.
Wow amd is that far behind huh? top end 5.0ghz barely even with i5 3.5ghz skylake.
Hee hee, will there be a 6771 that runs at 3.5Ghz to 4.1GHz? I clearly remember buying a 4770 non K base at 3.4GHz, and a 4771 for an extra $30 had an earth shattering base of 3.5GHz was also available. Guess which one I went for? Can't see anything here, have a 5930K in my gaming box. For SNB sure. IVB why not. Haswell eh.
