Intel roadmap update: Skylake alongside Broadwell, Broadwell -E Q1 2016

That's certainly true, but how many cores can it be spread across. Is it auto chosen or do we get to choose how many cores can be used by it?

DX12/Mantle spread load across more cores. So having more cores could be beneficial in the future. I.e 6/12 core/thread CPU might have long legs VS similarly priced 4/8 core/thread CPU.

DirectX 12.

Mantle.

http://www.firaxis.com/?/blog/single/why-we-went-with-mantle

DX12 does spread the load over more cores ye, I didn't say it didn't.

I said it reduces core usage, due to being much more efficient.

The only DX12 benchmark I've seen so far is the one during Siggraph 2014, where they demonstrated that the CPU used 50% less power running dx12 compared to running the same benchmark on dx11:

Video of the benchmark:

The Microsoft attendant there talked about how DX12 drastically reduces the CPU overhead, removing the bottleneck of a slower CPU from the equation.

For example, Mantle shows the best performance increases on APU's, and low performance CPU's.

Seems to be DX12 is all about reducing the CPU overhead, that bottlenecks APU's and weaker CPU's in desktops etc.

Would be cool if they released this demo to the public

+1

DX12 and Mantle are both massive progression. Hopefully over the next few years we'll see all cores being utilized. I have a feeling 8 core will be the next standard like 4 core has been for years. Overhead removed for gaming and GPU's able to reach max potential.

Dying light could sure use DX12 or Mantle

Getting some weird slowdowns in outdoor areas now..

Yeh I really do wonder when Intel will be force to release a mainstream 6/8 core.

I very much doubt they'll release one before Zen comes though.

opethdisciple · 31 Jan 2015 at 18:22

Im dissapointed that the next chips (Skylake and Broadwell) are still 4 cores.

Jokester · 31 Jan 2015 at 18:24

In all likelihood it'll also mean Skylake's successor will be 4 core only on the mainstream socket.

WingZero30 · 31 Jan 2015 at 18:31

Reading through the wccftech article, I found the highlighted part confusing regarding Skylake unlocked processors:

http://wccftech.com/intel-2015-2016...adwell-kseries-q2-broadwelle-arrives-q1-2016/

The story gets more interesting with the next update which is in regards to Skylake. For some time now, we have assumed that Skylake-S and Skylake-K will be two different series however the roadmap has summed it entirely different. As seen, Skylake-S series is featuring three different tiers of chips. The 65W and 35W will be the standard mainstream design for the platform which will feature a locked multiplier and will be compatible with the LGA1151 socket featured on the Z170 series motherboards. The third tier are the 95W unlocked chips with the “K” moniker that means that Skylake-S will be an unlocked design from the start and no need for the K-Series would be required for later on. We can expect a refresh in the future but it’s a breath of fresh air

Does this mean that unlocked Skylake cpus won't be called Skylake-K anymore or would these be just called 'Skylake-S unlocked' ??

Lol the terms are getting confusing :confused:

Yeah it looks like Skylake '14nm' > Cannonlake '10nm' are both on LGA1151 and 4 cores 8 threads. So whatever comes after will very likely feature more cores.

Some are predicting that sometime after, the successor to these will be BGA SOC's. I guess if that's true small form factor might become main platform, with traditional big tower desktop becoming even more niche. I'm sure some form of LGA socketed chips would exist but with less choice. Nvidia said that with Pascal and beyond everything is going to shrink as well. Maybe from 2017 and beyond there will be big changes with traditional large desktop PC's becoming less and less common. I don't mind tbh, if they can shrink it down and take up much less space while giving high end gaming performance I'm all for it :-D

. As long as I can change GPU's that is

Yeah I read that as you did. From the start Skylake will be unlocked meaning there's no need for a 'K' moniker. Maybe the motherboard will dictate if a chip can be unlocked. In a tier, so low end / business chipset HXX 1151 No multiplier changer. Higher end ZXX 1151 chipset offers full multiplier unlock. Something like that..

My brain hurts! Lol

Coming from my last PC build in 2004 and the one I’m on right now you may as well show me a field of tulips. Right so if I was getting a good system in time for Win10 release and wanted on the new stuff I take it this skylake is the way to go. Puzzled you say its only quad cores as I had set my sights on at least six. Wanting to get a new system to get back playing some games as the 2004 build that has done me proud gave up the ghost on the game front 2007-8. Think the last game I played on it was BF2 Project reality mod. Poor thing started getting Blue screen of death after an hour or so playing so gave up on games.

Hoping later in the year to spend £1200-£1500 on getting something to play Elite and Dayz and a few others. Bought a split new car last year so it put the old PC on the back burner but happy now to wait till Q4 this year. Having only used a single core AMD Athlon 64 all these years on XP anything is going to be a huge Jump for me.

WingZero30 · 31 Jan 2015 at 19:21

Going by the roadmap if Broadwell-E is being released in Q1 2016, then it's likely that Skylake-E may get released one year after in Q1 2017. So there would be almost 1.5 year gap between mainstream and high-end Skylake releases.

Perfect_Chaos · 31 Jan 2015 at 20:25

Seen some mention that pcie4 will be needed for hbm gpu's, i don't think it'll be needed for a few years though. Don't think that's coming till Skylake-e either.

It looks like it might end up going that way. I personally can't see them releasing
a high-end Skylake with 6 and 8 cores soon after releasing Broadwell-E.

Things could change thought if AMD is set to give Intel some real competition
next year especially at the high-end desktop market.

Then we could see Intel releasing a fully unlocked clocked high-end
Skylake-E with 6 and 8 cores.

On the roadmap, the TDP of Haswell Refresh (HSW-Refresh) K version is listed as 95W. However 4790k and 4690k have TDPs of 88W??

Good spot, maybe they just rounded them up weirdly?

Or maybe there's some more Haswell Refresh chips to come before Broadwell?

My last desktop was similar to yours probably (3200+/x800xt/2gb/WD Raptor) and although I got a Core 2 Duo laptop in the meantime I couldn't game on it as it just got stupidly hot.

I went to the system in my sig over the course of Aug/Sep 2014 (waiting for the 970) and was blown away as expected.

I think I will probably look to sell and get a Skylake rig as my intention is too keep more current, more often and I just know I won't be happy on DDR3 when DDR4 is mainstream.

Broadwell will have to be very good to tempt me.

Of course if we ever see -E ITX I might have more choices to make.

Remind me again, what platform is Broadwell-E coming on? X99? Or a brand new one. Currently looking at a CPU/mobo upgrade, and this has thrown a spanner in the works!

My current Desktop. AMD Athlon 64 3400+ at 2.40GHz and 1.5 GB RAM on win XP. NVIDIA Geforce 6800GT 256Mb.

Built by a local Shop with the wee sticker saying Built Nov 2004. To be fair it’s not really let me down apart from the odd times its died on me only to come back to life over a few days with reinstalling the OS. I expect MS windows has come on a lot and a lot easier to keep in shape
