DDR4-4268 WOWZERS. There is hope for the next couple years DDR4 will keep taking off and memory/timing overclocking will be a thing again .

Launch schedule of mobile Intel Skylake processors



www.cpu-world.com/news_2015/2015081801_Launch_schedule_of_Intel_mobile_Skylake_processors.html

Instead of delaying they pushed forward some models. Looks like Surface Pro 4 will be ready for an October launch.

Skylake notebooks will appear in September

This didn't happen during IDF 2015 keynote but we did want Intel did show some notebooks. Nothing too special, just something a bit something sexy as a Skylake U Dell XPS 13 successor or a new RealSense camera based tablet.

Intel had a separate big session talking about gaming. Two VPs showed up with two gaming notebooks from EVGA, MSI but with vague details. It is a bit like aliens we know they exist and they will come soon, but at the moment we are "not ready" for the secret.

Our industry sources have told us that we should see some Skylake U and H based notebooks in September. The sales and availability will happen in later part of September for many customers.

In other words we expect that everyone will introduce their new designs at Berlin based IFA consumer electronics show that takes off in first days of September 2015.

Which OEM will be the first?

New presentation: Power Optimization in Intel® Graphics Technology, Gen9

SoC-Level Improvements = More Power For Graphics!
1.Aggressive power reduction in the CPU cores and elsewhere
2.More Intel SpeedStep® technology domains: System Agent and EDRAM I/O
3.Memory-side eDRAM
4. Double throughput of LLC miss handling

G.skill is showing off new memory at IDF. Does anyone think this stuff is even worth it? Seems like all the super fast memory is not available in 2x8GB either.


Insanely fast (and probably expensive), too bad there's no 2 x 8GB version.

Has Intel disclosed L1 read/write numbers? Haswell has enough of resources to pump VMOVDQA's at very nice rate and enough to sustain FMA. Now question is, can you really push Skylake core without AVX512 instructions? Without input from Intel, anything is speculation at this moment.

Read and write appear similar between haswell and skylake for L1 with skylake hitting closer to peak.

You sure that Skylake's caches are fully inclusive?

Unless intel has changed things the LLC is always inclusive. Other caches are also inclusive though there may be exceptions at points in time.

Can those building Skylake systems start a separate thread please. This 4000 post long thread about everything Skylake related is getting a bit preposterous.

Core i7 6700K and Core i5 6600K owners can you please post your overclocks, voltages and cooling used? Oh and don't forget the CPU-Z Validation link/printscreen. We should do a ranking like other forums do.

Everybody waiting for 6700K... I ordered a 6600K, haha. Will probably resell for a 6700K at some point in the future but I mostly game anyway so I'm not sure if about 1.5 frames per second is worth $100 anyway.

Also got this headed my way:
http://www.newegg.com/Product/Produ...27889&cm_re=gtx_980_ti-_-14-127-889-_-Product

And this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16824260239
Which was a slickdeal off dell a couple days ago for $774 w/ 300$ dell gift card

OH JOY NEW BUILD

Will post pictures.

I am in no hurry so I will wait for 6700k and I know what my build will be. Asus Maximus VIII hero, 6700k, 16GB gskill or corsair(availability) ddr4 3000 memory, Samsung 256GB SM951 M.2 SSD on the PCIe 3.0 slot and of course my SLI 970s.

We should probably do this in a separate thread so they don't get lost in hundreds of pages of arguments.

Looks right to me.. Skylake beats Devils Canon i7 in single thread.. (Thanks Edrick).

Single thread scores look good but I'm getting low multithread scores, they vary each time but the highest was less than 3000. It was only using 60% of my cpu at the time. Might just be a Skylake Multithreaded bug that needs ironing out.

It gives dual core non ht chips the same score ST and MT.

Processor power settings?

Is that for me? If so it definitely is not the case, every other test can make full use of all the cores and whilst on a medium overclock Asus suite reports that in extreme cases the CPU can draw over 116W. From what I can see all power settings are completely unlocked.

So...NCIX (Canada) has the 6700k listed now as pre-order for $469 CDN (4790k is $439 CDN, so not a horrible gouge)

The kicker is this: "This item is not yet available but you can pre-order this now. We will ship this product shortly after its estimated arrival date of 10/02/2015"

And it gets worse, Intel is binning for Canada:

"INTEL® CORE™ I7-6700K Processor (8M Cache Up to 4.10 GHz) FC-LGA1151 Retail Box" - Those Canucks will never miss that 100mhz drop - even if they complain, tell them Intel uses American Ghz which are stronger due to the exchange rates.

:biggrin:

Thanks to AMD for being so poor, so absolutely awful, that Intel has been able to essentially sit still with no real innovation. We all suffer when there's no competition.
Except that you seem to forget that ARM architecture exists, you are also ignorant of the fact that the pc market is shrinking so Intel has to keep innovating to prevent a total collapse; except for those things you also seem not to have read the previous dozen pages and news about IDF, from IoT, to Skylake architecture. So here's a spoiler for you: Skylake is not - NOT - the same architecture as Haswell. Skylake is the work of a skilled, well funded team that worked five years to improve what is already superb (so with their time and bugdet, the Skylake team did not do nothing and did not intentially cripple the architecture; that would be very bad if Intel management allowed such drain of money). The result is improved power, improved performance, efficiency, overclocking and more.

You know guys, I seriously think Intel just f* up big this time.
I mean that i5 is on par with a much faster Haswell chip, it has much better graphics than an equal EUs count only for the bandwidth... and we are not going to see L4 in mainstream Skylake?

How big would a 128/64MB, 14nm eDRAM be? Some 40 to 20mm2 and it could easily improve BOTH the CPU and GPU.
Plus they wouldn't even need to make the die bigger to include it: just cut the IGP some 20/30% and get back that performance with the cache alone, while probably having same power consumption, one die only and a handy L4!

I'm not an engineer (still) but something fishy: either that's lack of competition right there or just complacency.

I can just hope current Xeons with eDRAM are such a huge succes that they implement it on all the line and mainstream part as consequence, still it's a sad looking affair from a desktop user perspective.
I'm quite sure 14nm DRAM doesn't exist. And Intel already said there would be more SKUs with eDRAM. But that will be on the SKUs where it makes sense, so not the slow GT2, but GT3 and GT4.

Edit: for some reason I ended up 100 pages behind, on page 60.
