Intel Skylake / Kaby Lake

Yes, I will be amazed if Zen comes out on time. Seems a *very* ambitious undertaking, especially for a company with the limited resources of AMD. Just look at the 390x gpu release to get an idea of what could well happen.

And that would seem a much simpler launch than Zen and all its variants. (new architecture on new process, plus HBM, plus ARM variant)

Or Seattle and Carrizo, both 2014 products. The never appearing Berlin APU.

I get the feeling they have been working on this for a while now. AMD got Jim Keller back in 2012. And since then the BD, PD etc haven't really received a lot of attention. Like perhaps they pulled resources from the bleeding pig around then.

Wow, forgot when Keller came back on board. Maybe someone from the industry can comment on this, but I thought it was 5 years to take a major uarch overhaul from conception to delivery

Haswell has been described as a "5 year journey."

The amount of work they put into it is nothing short of impressive. Extracting better IPC/ST performance out of these chips only gets harder and harder, I'll give the benefit of the doubt to the competition but I don't think they'll match Intel in this metric anytime soon.

Here's to hoping...although, I won't be holding my breath. If Zen turns out to be half of what it has been built up to be by a few people around here, though, I'll be buying one myself.

Yea, well a few people also tend to be shall we say "very optimistic" with every new AMD release. Then reality sets in. But perhaps Zen will be the one that finally does make AMD competitive again.

As far as my own expectations go, I'm sure it will have a much better IPC than what they have now. But that isn't a very high bar. I do think Sandy Bridge performance is well within reach though. While I guess anything is possible, like coming out with a 'Skylake Killer', I find that extremely unlikely. Winning the lottery unlikely.

So, if we are to believe the rumors, there will not be a successor to the 4790K out at launch. That is slightly annoying to me, as I much prefer a to have a maxed/"pre-OC'ed" **90K CPU (and pay a premium for it) than trying my luck with a **70K.

 

[Novacius]

That hasn't anything to do with the names. It was 2600K, then 2700K, then 3770K, 4770K, 4790K and now it's 6700K without the "70" or "90" again.

 

[CakeMonster]

Ok, my bad, I should probably have been more specific. I had forgotten the model naming on the Skylake chips.

My point; The 6700K seems like an obvious successor to the 4770K, being clocked at 4.0/4.2GHz. For comparison, the 4770K is 3.5/3.9GHZ, and the 4790K is 4.0/4.4GHz.

Given that the speeds are usually bumped up 0.1GHz-ish for each generation, and that we are doing a two-generation jump from HW to Skylake, we won't have any successor to the 4790K. For now at least.

The 4790K came out a year after the 4770K, so we will likely have to wait a year to see if there is a successor to the 4790K.

Seems like Intel is clocking the i7 at stock speeds pretty close to what the max is.

Exactly. Whatever comes out for the skylake refresh will be the "successor" to the 4790k. Actually, technically it would only be a "successor" if they come out with another slightly modified architecture special model like devils canyon. I wonder if the TIM for skylake is the supposedly improved one used on DC.

There is no basis for this assumption. If you happen to have a secret source, then go ahead and spill the beans

 

[PG]

Jumping to conclusions based on clock speeds alone is a bad idea, especially at this time.
There have been articles saying how Skylake will be a big jump forward like Conroe.
A new architecture may have very different performance at the same or even lower clock speeds.

 

[alyarb]

does anyone know the number of pipeline stages in skylake?

That was some posting from WCCF Tech, the most reliable source on the internet. Later leaks showed about 15% improvements and similar clockspeeds to Haswell.

I think Brian Krzanich does. And all the engineers that designed the beast.

I'm not buying into the 15% IPC improvements just yet, I wanna see some confirmed benchmarks.

That's basically what the 4790K is.

Agree, if I recall 2 benchmarks showed 15%, the other showed little. I would settle for 10% overall. Actually, I just want to see BDW-C and Skylake released without any further delays.

 

[Dave2150]

Any news of the DDR3/DDR4 support on Skylake?

As I understand it, regular desktop DDR3 will not physically fit in DDR4 slots.

Will there be two versions of some Z170 motherboards, some with DDR3 slots and other versions with DDR4 slots?

Or will some Z170 motherboards feature the 'uniDIMM' slots - which as I understand it, as the laptop style 'SO-DIMM' slots - which can physically fit DDR3 and DDR4 SO-DIMM's?

I'll be moving to regular DDR4 dimms when Skylake launches, though I'm curious as to how the desktop Z170 motherboards will get around this problem.

You know, if Intel wanted to improve IPC they could do so 10-fold. But you'd pay for it with 1/10th the clock frequency. The trick is 15% IPC while maintaining clock speed.
