Which Intel is stubbornly not giving us without going to their enthusiast platform.

You a doctor yet ?

That's what x99 is for I guess...

Indeed, I currently have a a 6core x79 chip Prime stable at 4.6GHz and I'm thinking, do I need this CPU power? Seriously considering going for Skylake and then probably only upgrading once 6 core chips come to the mid range socket (presumably in 2 gens times as you have to suspect that the Skylake die shrink isn't going to have it without major design rework). Then subsequent upgrades will just be when they add more cores as the days of +50% preformance improvements from IPC & clock rate boosts are long gone.

Were you expecting more? We've not had anything but small IPC increases since Sandybridge in 2011.

I was!

I suppose it means I can save my disposable for GPU upgrades, because there's no way I'm replacing my current mobo and chip for this.

stick with your 6 cores until dx12 is in the wild...in case the extra cores really help.

What's the timeline for that?

Skylake should perform better on high end MB this time as no onboard VRM so good power and VRM on the board are critical.

Is this it? A 10-15% performance improvement over current DC chips? What else does Skylake offer other than a performance improvement that is minimal?

I was quite looking forward to a new system build when these come out, but it seems pointless unless I'm missing something obvious (which is more than possible).

10-15% IPC increase is quite solid over the 4790k IMO. It's more that we've had between two desktop mainstream CPU's for quite a few years. It's most likely the biggest jump we've had since Sandybridge.

We also get the vastly improved Z170 chipset - which has PCI-E v3 lanes from the CPU to PCH, giving much more bandwidth for PCI-E SSD's, compared to what Z97 can offer.

At the moment if you want to take advantage of a PCI-E SSD to it's fullest extent, you need a x99 system. Z170/Skylake will mean you don't

Also we are yet to see how well these Skylake CPU's will overclock - they may be absolute monsters! It's a good sign that the base clock is 4Ghz on the 6700K - which hasn't decreased from the 4790k, despite the new 14nm process.

You know my feelings on clockspeeds.

However I think 7nm InGaAs will really fly. What a shame they insist on milking the last drops out of silicon. I wonder if it will be possible to hold on til 2020 with Sandy...

If you compare Haswell with Skylake in terms of instructions set, then they are identical. Skylake was meant to have AVX 512 instructions set but these won't be available in the consumer chips. Although Xeons would have some of these. I wonder if this means that Skylake-E would feature AVX 512.

Cannonlake on the other hand packs quite a lot of these new instructions.

I'm assuming Cannonlake is the die-shrink of Skylake?

Yeah it is.

But why Intel would introduce new instructions in the die shrink remains unclear. From this perspective, it makes Cannonlake more attractive.

Orangey · 24 May 2015 at 15:32

I think I read somewhere that Skylake-E will have 512 disabled in the microcode.

This is disappointing if true

Atleast Skylake-E should feature new instructions as these high end cpus would be used for more tasks than just gaming.

Guys why all these speculating threads!! what ever Intel offer always its moan moan moan.

U all want 50% increase for less money, using less power!!! Wait and see. If Skylake does not reach your expectations or criteria to part with your cash don't change. All these threads are so no need when moaning about perspective unconfirmed performance occurs.

Yes let's not discuss upcoming CPUs :confused:

In quite happy to invest my money in other hardware that will give me more of a boost. I'm actually looking forward to the VR headset battle that's due to take place amongst manufacturers.

Knowing that the system I built 2 years ago will still be holding its own for another 2 years isn't a bad thing!

Hope, you testing/tested one at least

I agree guys with IPC increase. From current benchmarks we know around 5-15%, its really not bad. Single core seems very strong overall. Cinebench score is awesome for stock 4c/8t CPU.

If we didn't spend half our time speculating, what would we talk about a lot of the time
