25W Xeons? That's neat. Can these fit into 11.6" laptops? Or will I have to wait for when they come up with 18W Xeons?

Excellent slides. I just want the release date of these Xeon beauties. Sad that the announced GT4e models are BGA.

Do someone knows if there is confirmation that non-K Skylake can be successfully overclocked via Base Clock? Because Xeons E3 V5 appeal depends a lot on that.

Let me just mention that Sandy and Ivy Bridge Xeons couldn't be overclocked at all, while their respective "locked" consumer counterparts could be overclocked 4 bins. What I'm saying is, even if non-K Skylake can be successfully overclocked via Base Clock, I don't expect that Xeons can be.

I understand what you are saying. However, intel just stubbornly seems to be trying to force the market to 1000.00 plus devices that have performance not that much better (or for coreM, probably worse) than my old work laptop from like 2009. Just not sure how many are willing to pay for that, especially since there are android tablets, cheap windows tablets, and smartphones that can do most of what an ultrabook or expensive 2 in 1 can do.

So if we want to compare 2009/2010 1st gen chips vs the 2015 5th gen broadwell chips (I am assuming skylake will be even better but we do not have numbers yet)

Effectively 35w 2010 chips get similar cpu performance to 4.5w core m, and core m has better graphics, ssd speeds, and battery life in a thinner form factor with less weight.

So the i5s 35w chips of 2010 1st gen i series were getting 2.14 to 2.44 multi thread in cine bench 11.5 according to anandtech bench. The single thread scores were 0.88 to 0.98. Now they had i7s back then but they were only dual cores for the 35w parts so all you gain were 2mbs more l3 cache and 133 or 266 mhz bumps.

The i7 quads back then were getting 2.8 to 3.0 in chinebench for the 2009 45w quads. Anandtech has in its bench a 2010 model i7 740qm which was a newer stepping compared to the 2009 models and thus turbo worked slightly better it got 0.95 single thread and 3.19 multithread in cinebench.

------

Core M broadwell since we have not seen any skylakes in the wild gets 1.11 single thread and 2.23 multithread in the passively cooled dell venue 10.8" tablet and 0.96 and 2.29 in the Asus Zenbook ultrabook which has better cooling but a lower model core m with less turbo and thus less single threaded performance.

The 47w i7 quads with broadwell are getting about 1.7 in single thread and over 8 in multithread in cinebench 11.5. Anandtech has not done any reviews yet but this is taking info from other sites.

------

Now if we compare 4.5 watt core m either broadwell y or skylake y vs the 1st gen 18w ultrabook chips it is night and day better on the core m as evident by this video

https://www.youtube.com/watch?v=Jat_P_UXMCA

Now the laptop on the left is a 11.6" timeline x 1st gen with i5. I used to have the same laptop with the i3 model and I say the i3 model is barely faster than baytrail in performance from a user perspective and this was including me doing an ssd upgrade and upgrading the ram to 4gbs. The i3 did not have turbo so the i5 could do 50% faster single thread due to a difference of 666 mhz turbo compared to the model I am familiar with.
The acer also had a horrible keyboard that was okay on a netbook but wen they used the same tech on anything 13 or bigger it truly sucked. And do not get me talking about the touchpad.

So, ETA to actual i7-6700 (non-K) availability in the US market? First week of October?

Yes, around end of Sept to First week of October.

Even though Intel Corp. has formally introduced code-named “Skylake” microprocessors for desktop computers, many of such central processing units are still not available. Apparently, Intel only intends to start their sales to end-users in late September.

It is not a secret that Intel’s latest CPUs for enthusiasts that feature unlocked multiplier – the Core i7-6700K and the Core i5-6600K – are in tight supply and are not available everywhere. According to sources with knowledge of the matter, shortages of “Skylake” microprocessors are conditioned by the fact that Intel had to unveil them earlier than it originally planned, which means that chip giant had to change its internal production schedules for such chips.
The family of mainstream “Skylake” processors for desktops will formally hit the markets in the U.S. and Europe on the 27th of September, reports CPU-World. Availability of such chips should be somewhat better than the current availability of unlocked microprocessors, but given the current shortages and pre-orders at retailers, it will take some time before all “Skylake” chips will be readily available at all times.

Europe got them since sept. 1st tho.

Only T models lacking. Else you can buy all models:
http://geizhals.at/?cat=cpu1151

Yes, I was jealous of Europe few hours ago. But I luckily managed to order one i7-6700K out of 5 that showed up at Amazon at its MSRP + tax about 1-2 hours ago, arriving between Sept 18 - Sept 22. Not jealous anymore

Still have to wait for the first week of Oct to build.

Wasn't aware of that one. However, since for Haswell the 4 free bins were removed, on both Xeons E3 and consumer line you were limited to MultiCore Enhancement. So they are equal in that regard at this moment.
Overclocking by Base Clock is not limited on Xeons, nor think they can do so. On LGA 2011 you can do it even on Dual Socket platforms, but Motherboard support is extremely limited. And the Base Clock doesn't go very high since you're forcing a LOT more components than on Uniprocessor platforms, so the headroom sucks anyways. Since Skylake decoupled a few critical things from Base Clock, it is extremely interesing what are the possibilities now. That's why I'm spamming around anxious for confirmation on that being possible.
Remember, since several generations ago (Westmere) that we don't know if they use the best bins for Xeons. They could potentially overclock more than consumer parts, and we would be back to the golden Socket 939 Opterons era.


Seems to be the physical size limitation of LGA115x again. Specially the IHS takes up a lot of space.
How much bigger would Skylake 4C-GT4 be vs Broadwell 4C-GT3? Skylake 4C-GT2 is 122mm^2 according to this, but without info on Broadwell 4C-GT3 die size nor on Skylake 4C-GT4 is hard to speculate. Besides, Intel said that it could be coming at a later date, didn't said that it was impossible.


Also, there seems to be a sort of mirror of Intel Ark with unreleased parts. Xeon E3-1245V5 here, price seems to be 321 U$D, part number CM8066201934913 (Only one result in Google, that one). Newegg has the Xeon E3-1246V3 for 290 U$D, which is nearly at MRCP.
Main differences when compared to Core i7 6700 (Since they're around the same price) are: Xeon Base Frequency is 3.5 GHz vs 3.4 GHz, it Turbos a bit less at 3.9 GHz vs 4 GHz, TDP is 80W vs 65W (But chances are that real power consumption is around the same), it supports ECC, the GPU Device ID is 0x191D (Intel HD Graphics P530) vs 0x1912 (Intel HD Graphics 530), and curiously the Ci7 6700 has vPro while there is no data on that site about the Xeon having it, but chances are it does got it.

It may not be the die size itself. But the layout.

Broadwell-C



We know the Core arrangement in the current Skylake dies are different than previous. 2 core pairs on each side of the L3.

CM236 Chipset is near identical to Z170. Only claimed differences according to previous slide is that CM236 supports USB OnTheGo on Port 1 and is missing SSIC (Which I suppose that its for Alpine Ridge) on Ports 2 and 3. I think both slides are missing those two features from each other.

Launch schedule of Intel Xeon processors

In addition to these products, Intel is readying workstation versions of Skylake processors. Skylake server CPUs for dual- and multi-socket servers are not one their 5 quarter roadmap yet, but we will see quite a few new Broadwell-based server products in the next two quarters.

Xeon E3-1200 v5 series for single-socket workstations will be released in the forth quarter of 2015. The processors will be a part of a new Greenlow platform, that will also include C236 series chipset. The CPUs will be built on Intel's latest Skylake microarchitecture and fit into socket 1151.

www.cpu-world.com/news_2015/2015091601_Launch_schedule_of_Intel_Xeon_processors.html

Not a lot of new info except what we already knew, as of now server 'Skylake-EP/EX' or whatever it is called (Purley Platform) is a 2017 product.

That i5-6400 in particular looks delicious, seems like a prime candidate for a $700-$800 budget gaming box.

"2 weeks" can't pass soon enough......

I'm assuming you mean the i5-6500? It is only $15 more than the 6400, and gets you 500 Mhz more base speed (that's half of a gigahertz, btw), and 300 Mhz more boost speed. It's by far the price to performance leader, in my opinion, if you aren't overclocking.

I'm interested to see how the temps are on these new Skylake chips, the non-OC ones I mean. Haswell seemed to run a little on the hot side for some reason, so I'm wondering if Intel "fixed" this with Skylake.

I sold a 2500k-based rig to a family member, when I still had it it always ran cool as far as I can remember. I just left the stock cooler on it and it's still humming along today. Even though there was heavy heavy gaming on it, the stock cooler was more than sufficient for my non-OCed 2500k.

Sandy bridge was amazing for the low-heat operation, ahead of it's time.

So far it's looking better than Sandy bridge for me. I've gone from a 2600k to a 6700k with very similar coolers and I'm getting idle temps around 28c on the 6700k vs around 36c on the 2600k both at stock speeds. The CPU temps are not much higher than ambient in the case which is awesome. Haven't had time to test load temps yet.

Also my power usage numbers look like this:

2600k+z77 mobo: 80w idle, 300w under load (witcher 3 gameplay)

6700k+z170 mobo: 55w idle, 240w under load

All other components besides CPU, ram and mobo are unchanged.

I really don't understand this at all. I'll be upfront about that. Could someone please explain to me how these chips can be so much stronger with regards to voltage than chips built on older nodes? I always though that Haswell shouldn't really be run above 1.3v. Now all of the sudden that's stock voltage? I'm just very confused on this and frankly wonder if the chip will die semi-young. Not trying to spread FUD, just wish to understand and gain confidence in this chip. I always run mine stock anyway.
