So now we have an LGA Skylake "K" @ 95 TDP after all. And the Broadwell unlocked LGA is only rated at 65 W TDP. Then what's the point with the Broadwell one, when they are released almost at the same time?

Also, Skylake-U already at the end of 2015Q2. Broadwell-U will have less than a 6 months life span? I wonder how many OEMs will create models based on Broadwell-U, which soon will be ending up on the discount shelves when Skylake-U is released just a few months later.

I'm getting more confused with every Intel release schedule update.

Seam to me that Broadwell is the worst Intel release of the last 5-6 years.

The point is to unlock the part that they ll want to get rid of at this time...

Yeah, but I'm thinking as a consumer. What's the point for me? Do you think the unlocked 65 W Broadwell can reach higher frequencies than the 95 W Skylake-K?

 

[AtenRa]

Broadwell is compatible with socket 1150, Skylake is not.

 

[mikk]

65W for Broadwell-K is a hint that this is aimed for AIO devices because of the GT3e GPU. Skylake-K should have a faster CPU but this is probably a 4+2 SKU.

That might be a good thing. If it's 65W at speeds similar to current speeds, that could make it a monster overclocker. Especially if they don't back down from the 4.0GHz base clock of the 4790K.

 

[Fjodor2001]

Because of the 14 nm problems you mean? Heat/ClockFrequency issues and similar that has been mentioned lately?

Can that really be fixed by an uArch change in Skylake? I'm wondering how much of an improvement we can expect going from Broadwell to Skylake.

 

[mikk]

Broadwell-K being 65W only and the new arrival of Skylake-K could be because of frequency scaling issues on Broadwell-K, see here: http://www.bitsandchips.it/9-hardware/5162-rumor-broadwell-k-consumi-eccessivi-ad-altre-frequenze

That does not make any sense though, if Skylake is 95 watts, it cant be less efficient than Broadwell, so either Skylake is clocked sky high (not likely), or Broadwell K is meant for AIO as someone else suggested and is not clocked that high.

 

[Fjodor2001]

Broadwell is compatible with socket 1150, Skylake is not.

Ok, so they kept one Broadwell desktop model just to not break the promise of LGA 1150 compatibility on Broadwell. :sneaky: Otherwise they could just as well have skipped along to Skylake directly.

Interesting link, but this brings up the question;

If Broadwell-K is pinned for low frequencies because at high frequency it draws an unexpectedly high amount of voltage, does that mean the 95W Skylake-K CPUs have such a TDP just because the process makes it necessary while it may have similar clocks to Haswell-K, or is the 95W TDP suggestive of having a higher-than-average performing K-SKU?

 

[Fjodor2001]

No Skylake U Core M 4.5 W TDP by the way. How come?

I'm not sure about 95W. Haswell-K is below 95W.

Because Skylake-Y is aimed for such a low TDP not Skylake-U. For some reason Y-models are missing in this Roadmap. Maybe Intel separated it for fanless SKUs because Cherry Trail-T is missing too, only Braswell.

 

[witeken]

This roadmap seems flat out wrong to me.

Braswell will not launch in Q2, but in H2. Skylake-U will likely not launch in Q3, but Q4 (maybe at the very end of Q3, but then it's still misleading).

I know Haswell-K is below that I'm asking because Im not sure if ts either 95W is needed to keep frequency similar to status quo with the "unexpectedly power hungry at high freq" design , or the 95W is because they are jumping some frequency up from the norm.

It's from VR-Zone. They are usually correct when it comes to roadmaps.

I thought roadmaps were pretty much subject to change at the drop of a hat?

Surely that there will be locked parts for the usual consumer, as for ocking dont know whose better but it s more easy with available multipliers than using all the old tricks like bus ocking.

Skylake will be without FIVR.

 

[elemein]

Skylake will be without FIVR.

Meaning the extra TDP is to make up for the lack of FIVR?

Thats too bad.

 

[frozentundra123456]

So where are the quad core mobile chips? Those are what I am most interested in actually. Since BW and SKL seem to focus on igpu, I was hoping for a "full power" mobile chip with a stronger igpu.

I agree though, not sure this roadmap is at all accurate. If true though, having Skylake K at 95W looks promising, but would they really have BW K and Skylake K available at the same time?

No FIVR = more MHZ.
