Intel Broadwell Thread

[Qwertilot]

Seems to hit rather more than 41 in the UX305:
"You do not have to hold the device, so even though it can get to over 47°C (117°F) between the display and the top of the keyboard, the palm rests and keyboard never get warm at all."

"Of course, if you are using the UX305 in your lap, it would be very uncomfortable as well, so watch out for that."

Entirely rational trade off for more performance in a notebook of course, esp as you need to thrash it for a while to get there which most won't with this sort of thing. Just not a trade off you could afford in a tablet form factor. You'd have to drop the performance.
(or up cooling somehow.).

Hence (as the review says) the yoga 3 ending up non trivially slower, even with a rather higher binned version of CoreM.

Would be amazing if the macbook didn't work well

what about the T300 Chi

Surface temperature when completely idle is relatively uniform on both the front and back at about 30 degrees C. Under heavy loads for an extended period of time, we were able to record surface temperatures as high as 43 degrees C on the right side of the tablet. In contrast, the opposite end of the tablet experiences almost no temperature change. Thus, expect one side to feel much warmer than the other even during regular use.

The similarly equipped ThinkPad Helix 2 does not experience as steep of a temperature gradient under load as the temperature rise is more evenly spread. The Core i5 Surface Pro 3 gets even warmer than our two Core M-5Y71 models despite the Microsoft tablet having an active cooling solution.

43c is not awful under heavy load. similar to ipad air 2.

Tablet portion of the device is 7.6mm thick and 12.5 inches. this is ambient temperature of 24c basically inline with the chart i posted above.

Assuming a 7.6mm thick device with 12.9 inches temperatures should be lower than 43c. This is also a WQHD display vs 1080p in the ux305 - to the extent that changes temps.


edit---- I would also point out that the IPAD Air 2 reaches 43c but the ambient temperature in the room is 21.1c vs the 24c for the asus t300 test.

All I want to know is if there will be a 4790k equivalent... a 5790k I guess...

Probably not. I think everyone would be really surprised if that happened. Maybe someone will get an unlocked Broadwell chip to beat DC with fancy cooling, but for the average enthusiast, no. Looks like Skylake-K is what we'll be looking for to decisively exceed a 4790K.

Bleh... So should I build a i7 4790k mini ITX build or wait for skylake? grrr....

Start a build thread in General and you'll get great advice. I happen to think Devil's Canyon CPUs are pretty nice still, and it's not clear when unlocked Skylake will be out. So I personally would just go for it, but honestly it depends on the usage case and what you are running now.

 

[DrMrLordX]

The 4790k is a great CPU. Most of its true potential is still untapped; sadly, that may be the case for a long time since so much of its performance is only accessible via AVX2 and/or using the HD4600 chip via OpenCL.

But even without AVX2 and with an un-utilized HD4600 it's still very, very fast. It will hold its value for awhile yet.

 

[ShintaiDK]

Broadwell-D products showing up.

The most noticeable tho, 4 DIMMs on a MiniITX.

Isn't the non-K version of Skylake supposed to be released first? Who knows how long we have to wait in that case...

 

[crashtech]

Anyone like me with a 4790K or better is sitting tight for the foreseeable future. I was hoping there would be something interesting to to with my Z97 board because I actually like to upgrade just for the fun of it, but not to go backwards in performance.

Unless I could also sell my R9 290 and still keep at least identical performance with Intel's latest Iris Pro, which seems highly implausible.

 

[CakeMonster]

Yep, I'm stuck with a Z87 and 4770K which doesn't even get past 4GHz. Still I have no more worthy upgrade alternatives than you. I just itch even more for it

I've thought long and hard about the 6-8 core alternatives for the last couple of years but I always drop it because 1) I have HT already 2) Its usually 1-2 years behind the mainstream platform 3) I don't like wasting money even though I can afford it.

A few benchmarks results from the new Macbook Pro (28W Broadwell-U).

CB15 OpenGL
Apple MacBook Pro Retina 13 inch 2015-03: 34.01 FPS
Apple MacBook Pro Retina 13 inch 2013-10: 20.77 FPS

CB15 Multi-core
Apple MacBook Pro Retina 13 inch 2015-03: 321
Apple MacBook Pro Retina 13 inch 2013-10: 261

CB15 Single-core
Apple MacBook Pro Retina 13 inch 2015-03: 126
Apple MacBook Pro Retina 13 inch 2013-10: 106

We could observe a CPU performance gain of approximately 19% to 23% (single thread, multithread) over the Intel i5-4258U Haswell processor used in the precursor. Therefore, it is comparable with the performance of Intel's i5-4200U CPU (TDP: 47 watts). (?)

In the OpenGL test, representing the system's graphics performance, the present solution has an edge of roughly 64% over the Iris Graphics 5100 in the precursor.

It will be at least 10nm, if not 7nm before a worthwhile upgrade for you comes along. Sorry to spoil your optimism

Buzzkil!

Are you implying that IPC increases will be even smaller on 14, 10, and possibly 7nm than what we have had since Sandy Bridge?

After all there has been a real (though not impressive) gain, along with general platform improvements. I could easily imagine upgrading before 7nm with the current speed of IPC gains.

 

[ShintaiDK]

IPC gains will be about the same more or less. What I guess he says is, you dont upgrade for 5-10% performance.

Looking on the 5960X, I would like to see cache expanded in the mainstream. 50% increase. So its up to 6 and 12MB. That may be the best way of getting a fast boost.

7nm would be my bet. My 4770 will stay with me for a looong time.

But, but...MorphCore! WCCFTech told us Skylake would be big and disruptive

But, but... greedy Intel toke it off the roadmap after they saw that they wouldn't have any competition from the ----ty Bulldozer architecture.

Yeah, they probably missed that the Bulldozer roadmap is coming to an end in favor of Zen...

Whoa! Did I read that right? Iris 6100 is improved by 60% over Iris 5100 in the new 13" rMBP?

In the OpenGL test, representing the system's graphics performance, the present solution has an edge of roughly 64% over the Iris Graphics 5100 in the precursor. Intel's HD Graphics 5500 in the ThinkPad X1 Carbon is outperformed by approximately 20%.

This is for the OpenGL test in Cinebench R15.

 

[coercitiv]

Whoa! Did I read that right? Iris 6100 is improved by 60% over Iris 5100 in the new 13" rMBP?

It also beats the HD 5500 in the Carbon X1 by a whopping 20%. Wait, what?!

That's what happens with selective reading.

The reason I had a O_O reaction is because perhaps I should see if Apple makes a Broadwell Mac mini (as designated by my thread in the Apple section) especially if also the SSD will be faster.

 

[Sweepr]

Windows notebooks with the same iGPU (HD5000) managed to outperform last year's Macs @ CB11.5 OpenGL.
Same could be happening here so they're not directly comparable.

Macbook Air 13 2014: 16.51
Lenovo ThinkPad X1 Carbon Touch (Haswell-U): 18.67 FPS
Asus AsusPro Advanced BU401LA (Haswell-U): 24.76 FPS
