Intel Broadwell Thread

[Phynaz]

what we know is planned for Broadwell.

What do we know is planned Broadwell? Yesterday you said there wasn't going to be a desktop variant at all. Your track record isn't so great.

I said Intel abandoned desktop with Broadwell, which is true except for the single token SKU they released because they had to keep the promise of an 1150 upgrade path.

Do you know of any other Broadwell desktop parts on the roadmap, high frequency and TDP variants in particular?

And they did keep their promise, LGA1150 users will be able to buy a socketed version of the fastest Broadwell out there (likely in Core i5 and i7 versions). While the competition is stuck with 3 year old Vishera and a refresh of last year's APU @ desktops Intel will have a killer HTPC chip with 65W Broadwell-K and the long awaited Skylake-S later this year. Doesn't sound like abandoning the desktop to me.

I recall spending a good number of posts trying to convince you of that very same thing in a recent broadwell thread. But now you're going to try to White Knight this thread like you have some insight into Intel's roadmap?

Broadwell-E.

 

[Fjodor2001]

Broadwell-E.

Not on 1150.

 

[DrMrLordX]

We'll all learn a great deal about Broadwell Iris Pro when people start buying and overclocking them. We don't have enough information to go on yet. Maybe if they gave us some frequency vs. voltage charts for Broadwell across a wide range of frequencies and voltages then we'd have something. The whole thing is a little weird, but hey, they parts are gonna be available in a few months, so we'll get all the answers we need then.

You're deflecting. You claimed you know the plan for Broadwell, I made no such claim.

Latest roadmap:

Please let us know where you find the 1150 desktop Broadwell SKUs, apart from the 65 W TDP one with Iris Pro.

 

[Phynaz]

Oh, so now you're moving goalposts that Broadwell has to be on a specific socket for it not to be "abandoned".

Please tell us what frequencies Broadwell is going to be released at, since you claim there won't be "high frequencies" (whatever that means).

Is that even an Intel slide?

What other socket do you think mainstream Broadwell desktop CPUs will be released on?

We know it cannot be high frequency 4 C, since it's only 65 W TDP and also has Iris Pro consuming power. Look at how the Broadwell U CPUs have performed so far, then draw conclusions from that.

It's well established that unlocked CPUs run above the published TDP. So the 65W figure tells us only about the intended usage scenario, and nothing about maximum clockspeed.

That said, my hunch is that enthusiasts with Z97 boards are going to be disappointed with Broadwell-K.

 

[Sweepr]

I don't see this as Devil's Canyon successor, just another product intended for different users. Lower clocks will probably hurt CPU performance @ stock but there's always overclocking and some people might take advantage of that massive GT3e iGPU. Users with Devil's Canyon and discrete graphics should wait for 95W Skylake-S later this year.

 

[crashtech]

And buy another motherboard...

Sure, but why would they rate the chip at a much lower TDP and frequency than it is capable of?

It would be like Intel rating the 4770K at 65 W instead of 84 W TDP, and setting the base frequency at ~3.0GHz instead of 3.5 GHz.

As has been mentioned, 4770R has a 65W TDP. These 65W Broadwell-K CPUs would seem to be the 4770R's successor. The wild card is the unlocked multiplier. Just a guess, but if you could somehow unlock a 4770R and disable the IGP, it might just act like a 4770K. So it's not entirely farfetched to presume that the Broadwell-K would have at least some overclocking prowess. How much remains to be seen.

What would lead us to believe Broadwell-K should have better overclocking potential than 4770K?

The Broadwell U chips released so far have been shown to have problems reaching high turbo frequencies. So that indicates the opposite for Intel 14 nm.

 

[ShintaiDK]

Broadwell U chips turbos much better than Haswell.

Users with Devil's Canyon and discrete graphics should wait for 95W Skylake-S later this year.

Unless Skylake clocks much faster (very unlikely) or has a big IPC increase (possible but unlikely given the recent releases) it won't be meaningfully faster than either DC or BW with overclocking taken into account. Broadwell-K will probably be more expensive given the edram, but any savings would get eaten by having to buy the more expensive DDR4.

 

[jpiniero]

It can hold it's turbo more/better, but the max clocks are lower.

 

[Enigmoid]

Clocks are the same if not higher.

 

[ShintaiDK]

The i3s without turbo is the most noticeable.

+100Mhz at 15W, +500Mhz at 28W.

 

[mikk]

I don't think so.

Saw my first Broadwell Laptops in the wild today. They had two broadwell models in the local Costco that I go to. I think they were the 15 watt U models, i5 5200u and 4xxxU. They were kind of generic looking models though, so could not say much. They also had an AMD FX-7300, but it seemed overpriced compared to the Broadwell models.

The device that really appealed to me though, was the Acer Switch 10. Really cool looking, the tablet part came off easily and was small enough to handle, and the overall size was nice. It was on sale for 279.00. Too bad Cherry Trail is delayed and wont bring more cpu improvements. The only reservation I would have with the device is the kind of marginal performance.
