Intel Skylake / Kaby Lake

[throwa]

How does the stock cooler for i5-6400 and i5-6500 stack up? Does it deliver "acceptable" cooling? I was just wondering.

I'm thinking that because the TDP has dropped from 95w to 65w maybe you can "get away" with just the stock cooler once again as was the case with Sandy Bridge some years back.

A while ago sold my i5-2500k rig to someone else, and I never added any aftermarket cooler, I found the "stock" cooler was acceptable for casual gaming. As far as I know, that rig is still humming along despite being 3+ years old, I haven't heard any complaints from it's new owner.

I think the HSF for those is the all aluminum one, it is only good for 65W.

If I put a 6500 into a build, I would use one of the few copper-cored HSFs laying around from Haswell 15 and i7 builds, they are rated to at least 88W.

First Skylake-U Iris™ Graphics 540 results out.

GFXBench Windows OpenGL - 1080p Manhattan 3.1 Offscreen (Top Scores)
- Iris™ Graphics 540 (15W Skylake-U GT3e): 63.5 FPS
- HD Graphics 520 (15W Skylake-U GT2): 39.6 FPS
- Iris™ Pro Graphics 5200 (47W Haswell-H GT3e): 61.2 FPS
- Gefore GT940M: 52.3 FPS

Note that these are the first Iris submissions, so results may improve. Still, 60% faster would be a very nice boost at the same TDP. Damn, I really want a Core i7 Surface Pro 4 now.

Do you have any idea how the 6500u and 6560u do in video editing. 1080p and 4k. Editing and rendering etc. I have a dell xps 13 which is going back because of some issues. There are 6560u iris 540 chips rumoured because they are listed in the manual and on a dell australia partner direct site.

Also, does anyone know when we can expect the 6560u to become more available, I notice only the SP4 has it so far, is there a reason its not in a Dell XPS 13 yet if it clearly looks like it's planned.

Also considering it's cTDP down is 2W higher and lower base clock 2.2ghz vs 2.5. Will that 2W cause the unit to be significantly warmer in most situations.

Thanks

Core i7-6560U has a 100MHz Turbo advantage. This, coupled with the eDRAM, should result in slightly better CPU performance than Core i7-6500U. You can check the impact of Crystalwell (eDRAM) here.

There's plenty of Core i7-6500U benchmark results at NotebookCheck and other websites, but unfortunately I haven't seen a single Core i7-6560U/6650U review so far.

Looks like Intel is having some troubles with 14nm yields so far. To put it in simple terms, Core i7-6560U is based on a bigger chip (2C+GT3 + eDRAM), harder and more expensive to manufacture than the more common mobile Skylake-U models out there. I think availability will improve (early) next year, Apple is expected to use these chips in their next generation Macbook Air.

No. Expect a minor difference in idle or CPU intensive usage scenarios.

What sort of price difference would you expect between the same laptop equipped with 6500 or 6560u. FYI the dell xps 13 config with the 6500u is £1150.

Thanks

It shouldn't cost a lot more. The recommended price for these chips is similar, but the limited availability could lead to higher prices (Core i7-6560U version).

Microsoft is asking £220 more for the Core i7-6650U next to Core i5-6300U variant of their Surface Pro 4, but we're taking about two closely specced Core i7 models here, so probably less than £100.

Slightly off topic question related to availability: I'm wondering how Intel handle the huge number of SKU they have; I don't think it'd make sense to stockpile each of them. So I guess they take orders from manufacturers and produce chips accordingly. I'm wondering how long it takes to fulfill those orders and how yields are impacting that. I'm not sure there's any public information about that whole process, but asking is free

Thanks for posting. That's massive for Celeron, Pentium, Core i3 and locked Core i5/i7 users, a good incentive to upgrade to Skylake. Looks like the Pre-Sandy Bridge era of Intel budget overclocking is (unofficially) back.

It looks like the Saga of the Unlocked BCLK is coming to a bursting conclusion with both ASUS and ASRock enabling overclocking the base clock frequency of non-K Skylake processors. From the looks of it, a simple BIOS trick will enable the overclocking capabilities.

We will update this news article with the links to the BIOSes enabling the BCLK overclocking when they appear on the web. Until then, have a drool over Elmor's 5.8 GHz Core i3 6300 or L0ud_sil3nc3's 4.9 GHz Cinebench R15.

Update #1: Elmor posted a bit more details on the unlocking in the forum. For now the BCLK unlocking is in experimental stage with most obvious drawbacks being the lack of power management functionality and some benchmarks like XTU not working properly. The BIOSes will arrive in the coming days as more fin-tuning is required.

AnandTech has a story on overclocking locked Skylake CPUs too:

http://www.anandtech.com/show/9848/bclk-overclocking-intels-non-k-skylake-processors-coming-soon

What's also interesting is that there does not seem to be a need for motherboards with the Z170 chipset normally required for overclocking. E.g. the cheaper H170 chipset can be used too.

The massive frequency jump from 3.8 Ghz to 5.8 GHz on the i3-6300 was done under extreme conditions though (liquid nitrogen cooling and such). With standard air cooling more modest gains should be expected.

 

[DrMrLordX]

Very interesting! It's sad that the iGPU disables itself unless you do not use the Intel drivers for it once the bclk is overclocked. Those with dGPUs won't mind so much.

 

[LTC8K6]

Except that this bclk deal could easily be ended for you after you've spent your money.

 

[ShintaiDK]

Then we dont have to hear the "price complain" of the Supermicro board anymore

Yes, that's not so good for those using the iGPU. Where did you read this (I did not find it mentioned in the AT article)? No workaround available?

That can probably go in the 'no shit' category. It did get to 4.7 and 4.8 air-cooled.

Screw Core i3, Pentiums will likely assasinate the budget market to AMD.
To make it better, if that is true... RIP unlocked Core i5 and i7. Or even more... if that is true, that means that Xeons will get a big benefit.

 

[njdevilsfan87]

The Xeon E3 chips are available for reasonable prices (ie. 4c/8t E3-1230 v5 for $275). I wonder if those will overclock as well?

It will remain to be seen what's possible. If you could get an i5-6400 up to 4.5GHz, it would really eat into 6600k sales given the $185 vs $275 price difference. 4.5GHz is trivial on the 6600k though, that large a BCLK OC might be challenging.Considering the price difference between the 6700 and 6700k, I don't imagine that sales of the unlocked i7 will be terribly affected.
The Xeons are way more interesting, since you can pick up a 4C 8T E3-1230 V5 for $260, which is less than the i5-6600k. If it is relatively easy to pop that CPU up to 4.5GHz, it would be a pretty good value.

 

[crashtech]

I think the locked i5s would be hurt most of all by widespread i3 overclocking. 6600K will still have its place.

 

[Sweepr]

I think the cheapest Celerons, 4C/8T Xeons, Core i3 6100, Core i5 6400 will benefit the most.

Wow so now cheap i3s can be overclocked too? Thank you, mobo makers

I wish I had an excuse to pick up a cheap i3 to play with but at this point I have too many CPUs/systems and my wallet is already very unhappy with me

Me too.
Even better if MB manufacturers allow BCLK overclocking on cheaper H170 boards.

Looking at Intel's current lineup:

Pre-order prices of the G3900 and G3920 CPUs are $48.26 and $57.75, which is about $6 higher than official prices of the G1840 and G1850 processors.

Celeron G3900 should be a nice little chip to play with. It's clocked at a fairly low 2.8GHz, pushing it above >4GHz means >40% better performance. New king of budget overclocking and worthy Pentium G3258 successor?

Core i3-6100 could become really successful. Looking at Eurogamer and other reviews this little chip is close to FX6300 MT performance at stock and destroys any AMD CPU in terms of per core performance. Jagat previewed what it is capable of with a mild overclock:

At 4.7-4.8GHz on air it will be close to locked Skylake Core i5 level of MT performance.
I don't agree that it will hurt Core i5 sales though. People interested in a 4C/4T CPU will still get one, especially if Core i5-6400 overclocks like its cheaper siblings.

At $250 a 3.4GHz (3.8GHz) 4C/8T Xeon E3-1230 v5 could potentially deliver OCed Core i7-6700K performance (or close to) for $100 less (even more if you choose a cheaper non-Z170 MB).

 

[Arachnotronic]

Sweepr, completely agree. It is now much easier to recommend an i3-6100 (and even the Pentium/Celeron chips) to gamers on budgets if overclocking is part of the mix.

Hope they don't nerf this...
