I thought Skylake Y would be 4W. Disappointing.

Hope there's an AnandTech podcast.

Maybe they are allowing for a bit more performance (better turbo/less throttling)? I mean considering the power the rest of the system uses, I think I would give up 0.5 watts on the cpu for better performance.

Edit: actually, and I have said it before, unless you have money to burn, or your company is providing the device, this whole Y line does not make sense to me. They have some really nice looking products, but the performance is simply too low for the >1000 cost. Now if they would put core Y in something like surface pro 3 for 500.00, it would sell like hotcakes.

4.7ghz at 1.38v spikes to 1.4v under some loads.

Seems stable. 10 passes of real bench so far.

72-79c temps under max load on quiet fan profile
1.4V on a 14nm core? Doesn't that worry you at all?
Temps are great but still, that vcore cannot be good for the health of that chip on the longer term...

They come with 1.3v on them stock.

Temps are cool.

The bios doesnt say the voltage is high

Well if 1.3V is stock then 1.4V is not a big jump. That is around 15% higher power draw with the same clocks (rough est.) and if you count in the OC then you are looking at about 35% or so higher power draw Vs stock. I thought that default voltage is lower than that, but if intel specced it at 1.3V then it is perfectly fine.

Yeah, a Lenovo Helix with Core m for 1900 euros is outrageous.

Can't wait to try the 72 EU + EDRAM part.

Entry level Surface Pro 3 uses Haswell-Y so I guess Core M is a strong contender for the Surface Pro 4 entry level model. Core i3 6100U is another possibility since a previous leak mentioned no Core M inside the Surface Pro 4.

Performance will be subpar with the A9.

As a fan of the iPad I really hope Apple's idea of a Surface Pro competitor is not an oversized iOS device at premium prices with a stylus attached. I don't see Apple selling it for less than $800-1000 and at these prices the Skylake Core i3 Surface Pro 4 would be a much better productivity device.

You might even be able to buy a cheaper Core M (Skylake Y) convertible device running Windows 10 from the likes of ASUS and others.

Is 1.3 the XMP voltage with the feature that boosts all cores to 4.2GHz? I found yesterday that there was a lot more heat than I expected from what I thought was stock voltages when in fact enabling these features had increased the voltage considerably to around 1.3v. Re-setting to default gave a lower voltage and much lower temps.

Why is it disappointing? If they can make it run faster @ 4.5W, while still keeping it fanless that's a good thing, ...or?

This is of course assuming they've managed to improve performance/clocks @ 4.5 W compared to 4 W.

So at what performance level would you consider the Y series to make sense? You do realize it's 4.5 W TDP right and has the main benefit of being possible to make fanless, so how much can we expect from it?

Or is it more that you would like to see it priced lower given its performance?

The word from Intel and ASUS was recommended to stay under 1.45 volts.

So I wouldn't worry about 1.4v

IDK why but going from 32nm to 14nm and we are using almost the same voltage now as with SB. But from what I've seen and experienced it's pretty hard to kill a CPU.

I have killed 2 and they deserved it

I just wanna see it more mainstream, in cheaper designs.

BTW, Sweepr, great job with all the news and stuff.

My board gives me 1.224v for a 4.2 OC on all cores (Turbo off, manually set to 4.2). I use the "Normal" vCore setting in the BIOS. So I assume that is stock.

System seems 24.7 stable, been on Arma 3 for a few hours and i can tell ive got a much faster system. FPS drops are much less severe and the FPS is much more stable in the town areas.

4.7ghz Skylake is like a 5ghz Haswell so im happy with the uprade from a semi stable 4.3ghz 4770k!

I am happy with my upgrade from a 4770 non-k Haswell also.

On earlier builds I've had troubles with setting a max voltage while still allowing the CPU to downclock and downvolt whenever its possible. I've had to at times lock the CPU to a voltage and constant clockspeed, causing me not to get any power saving benefits. If I didn't, then it would overvolt like crazy compared to what I told it to in BIOS. Is this still an issue in 2015?

I don't have that issue but I use an offset voltage. So basically I apply something like +.125volts to the CPU (I forget the exact number)and when it clocks up it stays stable because I applied enough but when it idles it drops to somewhere around 1.6ghz and just over 1.1v. If you set a constant voltage manually you don't get that power savings at idle.

That looks about right for the stock voltage from what I remember. With this board when I set XMP, it asks me if I want to make additional CPU optimisations to give a 4.2 turbo on all cores, I believe it adds the voltage just so it can be sure that it will work on weak chips. Not that I expect any of these chips to be that weak.

Perhaps one of the most eagerly awaited possibilities of Thunderbolt 3:

Intel says Thunderbolt 3 will bring external graphics to laptops





The lines between desktop and notebook computers are getting thinner and thinner. Intel has announced plans to bring its enterprise-class Xeon processors to notebooks, and offer unlocked, overclockable K series processors for notebooks later this year. Want even more power in your notebook? How about an external graphics card?

Intel says notebooks that feature Thunderbolt 3 ports will be able to connect to external graphics docks. This lets you use a high-power graphics card with your notebook while powering up to two 4K displays (in addition to your laptop display).

Thunderbolt 3 uses a USB Type-C reversible connector. That one tiny Thunderbolt 3 port can be used to connect a docking station that lets you output video to multiple displays, connect an external hard drive, keyboard, mouse, headphones and Ethernet cable. And since Thunderbolt 3 can handle up to 100 watts of power, you can also charge your laptop through its Thunderbolt port at the same time.

Intel is showing off a sample graphics dock with an AMD Radeon R9 M385 graphics card at IDF in San Francisco. But we could eventually see third-party graphics docks that let you add your own graphics card. This could let you buy high-performance graphics cards designed for desktop computers and use them with your notebook. And it could also let you upgrade in the future when you’re no longer happy with that card’s performance

Core i5 6600T Geekbench 3 Score
http://browser.primatelabs.com/geekbench3/3243697

First Geekbench submission of this 35W T model is ~25% faster @ MT than the best Core i5 4590T score (also 35W) and about on par with some locked 84W Haswell Core i5s. Skylake is bringing substantial performance boosts at lower TDPs.

Better IPC + higher stable clocks, nice to see a Haswell user satisfied with the upgrade.
