More Skylake details

Recommended Posts

Just for everyone's information -- it looks like the first Skylake chips and motherboards will be out August 5th, and priced about 10% higher than Devil's Canyon.

I wonder how soon the first FSXMark11 results will be available?

Thanks for posting that James. Right on time, I will be building my new rig right about then.

Is it worth waiting for Skylake when you compare to these 2 processors?

 

Intel® Core™ i7-5930K Processor (6-cores, 15MB Cache, Overclocked up to 3.9 GHz w/ Turbo Boost)

ntel® Core™ i7-5960X Processor (8-cores, 20MB Cache, Overclocked up to 4.0 GHz w/ Turbo Boost)

Considering those currently go for $632.51 and $1,028.99, respectively, while the i7-6700K is priced somewhere below $400.00, yes, it is worth waiting.

Can't wait to see the overclocking performance of these chips.  Hopefully the thermal paste is such that they will stay cool out of the box using a descent heat sink.

Are these guys going to be cold solder [epoxy solder] between die and heat sink? Or crappy old thermal paste we can de-lid?

I don't expect to see any thrilling increases in performance over previous generation CPUs. The processor chip industry hit a brick wall several years ago, and I am not convinced that they have found a way to knock it down yet.

I heard 15% increase Chris.
 
I'm on a 3770k though, so hopefully a decent improvement.
 
I read this morning that it is crappy tim not solder. Not 100% verified yet though.

Small die, and paste.

Voltage regulators no longer on the chip though...

Remember Intel’s FIVR (Fully Integrated Voltage Regulator) innovation that was something of a hype back before Haswell was released? Well we have just received some technical documents which suggest that Intel is abandoning the FIVR design.

 

 

 

Intel recon it's the most significant processor for a decade.

Well, we will just have to wait and see. All I know is that if my i5 2500k powered PC had not suffered a motherboard and GPU failure last July, I would probably still be using it now (with a new graphics card).

I wonder what 15% translates to compared to my 2500K ? (not sure if that increase is compared to the latest and greatest chips today).

So i2500K to Skylake (at the same clock speed) will be about a 35% increase in speed.  Pretty good in my book, not to mention the increase in ram speed (or throughput) from moving to DDR4.  I think the key will be "at the same speed".  I am currently running my 2500K at 4.8GHz.

I am pretty sure they will oc to about 4.5 as the turbo goes to 4.2 down from 4.4 on the 4790k.   These are  smaller chips with most likely high heat.  Some of that 35% would be lost due to lower oc's in my opinion.  I am at 4.9 ghz on my four year old 2700k; I suspect if you are at 4.8+ ghz on sandybridge technology; you may get 15-20% as the oc would be less.  If your min fps at a heavy airport is 23..you may get 3-4 fps more in the heavy situations.  I guess we have to see how they oc; SB was so big due to the ipc gains as well as the oc headroom they gave.

 

DDR 4 will be slow to get the benefits in the first 6 months to a year as the ram speeds are slower and timings are less than good ddr3 sticks that are in the market, but we can hope for some bigger ipc gains....alot of these early reports vary from 6% single thread from haswell to the link in this theard with higher results for skylake...who knows.   I am enjoying my sim in the current set-up though, so no rush I guess!

So just stick with what I have for now.  God I hope my overclocked chip hangs on.  Just so I know, what are the options if it goes ? Is there a drop in that will work with my current LGA1155 MB and Ram ?

lol; I am in the same boat!  My vcore on load still stays at 1.35-1.36 so I am lucky.  I only manage a one hour flight once a week, so my rig has not had much use over the years though!  Think you can use your ram; think Skylake has a new socket set, so you may need a new mb though.

It's a new socket, so yes, a new board is required. Socket 1151. Z170 chipset.

 

Some vendors have already shown off their boards.

Hopefully with the voltage regulators not on the chip they might be more thermally efficient than you think.

You'll also need new memory (DDR-4 instead of DDR-3).

Some mb's on the new chipset allow ddr3; which may even be faster as the initial ddr4 sticks maybe not the best; they will improve in quality and selection 6-12 months from release of SL when ddr4 becomes more mainstream.

Lets hope; if they oc to 4.6 then they may make some decent headroom with their ipc advantage!

If you google the full set of leaked specs mentioned in that clip, you'll find that Skylake does dramatically better in some tests, but shows a much smaller improvement (or, in a few cases, even worse performance) than Devil's Canyon in others.

I also note that Barron's, in reviewing Intel's 2Q results, is now predicting that manufacturing issues will cause Skylake will be delayed to 4Q at the earliest, although Intel hasn't said anything about a delay.

The percentages just don't impress me these days. As far as I am concerned, there is little incentive for even i5 2500k owners to upgrade if they have healthy overclocks and stable systems. You can talk about DDR4 RAM and fancy new chipsets all day, but I still say that the processor manufacturing industry is at a virtual standstill, and has been for quite some time. In fact, the Intel Sandybridge line was probably the last processor iteration that even comes close to "revolutionary" status. Everything since then has been evolutionary at best. My i5 4690k powered system is only a year old, and yet it feels more like a "warranty replacement" for my failed i5 2500k PC (purchased back in 2011) rather than a big leap forward in processing power.

 

Not that it matters to me. If CPU performance continues to rise at its current rate, I will not have to think about another system upgrade for several years :smile:

Not that it matters to me. If CPU performance continues to rise at its current rate for the next few years, my i5 4690k will be a decent performer for some time to come :smile:

 

 

I agree with you on all of that.  Will keep on dusting and cleaning my processor and mb for some time to come.  I will keep my eyes abreast on how skylake oc just to keep my techie side at bay! :)

Unless one needs lots of processor threads there has been no CPU improvement worth getting excited about for years now.  ShouId Skylake buck that trend I'll be thoroughly suprised and delighted. It's almost sad that my two years old 4.5ghz 4770k system is still 'top shelf' perfomance wise in the quad core arena.  Even more sad is that the conroe i5 laptop I got over 5 years ago is still worthy; I wonder if it will instantly flunk the Win10 "free for lifetime" test :lol:.

Intel have announced that they have postponed the switch to 10nm due to technical fabrication issues. Intel say they will instead extract more speed from 14nm. They don't say how they will do that.

 

As for the Skylake benchmarks, yes, some are high some are lower. so perhaps we need to consider which one of those benchmarks [if any] are applicable to performance for we gamers?

More's law is under threat.

 

First it was performance doubling every 12 months, then 18 months then two years. Now, with the delay to Cannonlake 10nm, it's the second time the 2 year cycle has failed.

 

Intel say the delay to Cannonlake is caused by the increasing difficulty of building transistors that small.

 

To address the lack of chips in the pipeline, Intel say they will release Kabylake 14nm chips. based on Skylake. Kabylake will be tweaked and faster Skylake I believe.
