Skylake Clockspeeds and benchmarks!

[Dave2150]

This been posted?

4-8% over Devil's Canyon.

These benchmark results were posted and debunked a while ago - it's just kitguru doing another clickbait article, for more views/money.

Still waiting for new leaks/benchmarks!

 

[Dave2150]

Do you have a link to the debunking?

Not to hand, though a simple glance at the 4790k scores show them to be inaccurate.

These are the same cpu monkey benchmarks from a week or two ago, somewhere in this thread.

The 4790k scores only 805 points in Cinebench R15, which is incorrect. Lookup any of the official 4790k reviews from Anandtech, ,Tomshardware and other reputable websites and it scores 850+ at stock, depending on the memory used.

If they can't even get the 4790k scores right, what are the chances they are accurate with the unreleased Skylake scores...

 

[Dave2150]

That's not really debunking. That's within the scope of difference you'd get due to different setups.

All you have to do is look at any benchmark thread and ypu'd get different results.

Many users setup their systems incorrectly - or use cheap memory that runs at lower speed and higher latency - in my opinion it's best to stick with the most reputable review sites, when seeking a benchmark score for a given product.

Hopefully we'll see who's right soon, when the benchmarks arrive

I'll be picking one of these up as a HTPC upgrade/downsize when they release, quite nice specs

More Z170 motherboards are showing up!

I still can't believe the Killer NIC lived on as a chip.

_____________________

I'm considering replacing my gaming SSD stripe with something newer when Skylake launches, two M.2 slots would be nice.

Yeh I'd never go near a Killer NIC, I'm sticking with intel.

I'll also be getting some nice PCI-E SSD's to go along with my Skylake build, hopefully there's more choice out by August/September

 

[Dave2150]

Are we ever going to get a decent leap in terms of cpu's? We seem to be getting 5% little baby steps every generation.

The leaked benchmarks right above your post show a 15% increase in IPC in cinebench and CPU 3D Mark Score.....

Though these benchmarks are weeks old, already posted here and have bee debunked on various forums already.

Asus Z170 Pro:

 

[Dave2150]

As patiently as I am waiting for Skylake-E, these motherboards are tempting me to upgrade from lga 775 to i7-6700K lol

I considered waiting for Skylake-E, though I've pretty much decided to get a 6700-k/Z170 combo, as I don't want to wait 12-24 months for an upgrade.

Z170 is a huge improvement from Z97 - We're getting 36 PCI-E V3 lanes with it (16 lanes from CPU, 20 lanes from the PCH. That will be good enough for me.

 

[Dave2150]

As things stand it appears I have four options with regard to Skylake as this is the definite architecture I want to upgrade to next.

1) Buy i7-6700K platform this year and sell some of my 775 stuff to recoup some of the cost.

2) Buy Skylake-E when it releases, sell the Z170 but keep DDR4 ram

3) Have two separate desktops; one with i7 6700K and the other one housing Skylake-E. (i7 6700K desktop can perhaps go to one of my family member)

4) Wait it out until Skylake-E and then sell some of my 775 stuff.

Too many choices

Yeh I'm thinking something similar - I'll probably go with 32GB DDR4 (4x8GB) for my 6700K/Z170 setup, just so I have 4 dimms ready for Skylake-E quadchannel memory. I don't fancy getting 4GB dimms at this point in time, too dated.

I'll expect that 32GB kit to last me 5-6 years minimum, making it good value for money.

The only issue could be if Intel make Skylake-E have hex-channel ddr4, not sure how likely this is - I saw the new xeons will use it, and Skylake-E is derived from Xeons, so who knows

 

[Dave2150]

Use the 5930k all the stuff you do will thrive on a hex core

I agree with this - if you already bought a brand new 5930k, then it would make sense to use it......

Skylake has the potential to be faster for games than Haswell-E (unless running Quad-SLI), as not many games use more than 8 threads. Games usually prefer higher IPC and higher clockspeeds. Though the difference between the two would be tiny.

For video editing though Haswell-E will be the best performer.

 

[Dave2150]

When is this due out then? August? Any idea on pricing?

Trying to decide what to upgrade first, my GPU or CPU.... I think a a 980ti/390x will benefit me a lot more though, as I plan on going to 3440x1440 in the next few months.

August/September. Pricing should be the same as the 4790k - maybe a extra £10-20 for the first week or two, early adopter tax.

Skylake will have I3's, I5's, I7's etc, and will completely replace and obsolete the curent socket 1150 Haswell lineup.

We should see a 10-15% IPC increase over Haswell, plus we're getting 36 PCI-E v3 lanes (16 for GPU, 20 for PCH, for storage/IO), compared to the pathetic 16 we get from Z97 currently.

 

[Dave2150]

I would imagine most will be DDR4, some DDR3 and a couple will be 2slots of one and 2slots of the other but you can only use one type.

The first boards featuring 2xDDR3 and 2xDDR4 slots were featured at Computex, though only supporting the H170 chipset (the non-overclocking chipset).

Biostar Hi-Fi series H170Z3 and H150Z5:



Haven't seen any exclusively DDR3 boards yet, or any Z170 boards featuring DDR3/DDR4 slots.

 

[Dave2150]

20 lanes of PCIe 3.0 from the PCH, but how does the PCH link to the CPU?

I get the feeling we'll see the CPU lanes used up for SLI/Xfire as usual, then all the usual stuff hanging off the PCH (SSDs, HDDs, GbE, Audio, USB3.0, etc) all connected by DMI, which is basically PCIe 2.0 x4. Yay bottlenecks.

I'd recommend reading the opening post of the thread, plus countless other posts in the thread, where it's explained that the Z170 chipset (PCH) upgrades the link to the CPU to PCI-EV3 (DMI 3.O) - enabling Z170 to have 20 fullfat PCI-E v3 lanes direct to the CPU.

So, 16 lanes for GPU's, and 20 lanes for everything else, which is a huge improvement from Z97 - enabling multiple PCI-E SSD's full bandwidth at the same time as GbE transfer, USB3 etc etc. No PCIe -2 bottleneck, that's reserved for Z97, Z87 etc etc.

 

[Dave2150]

Thanks, I missed that.

Even so, DMI 3.0 is still only equivalent to PCIe 3.0 x4.

So you're still putting 20 lanes of devices, plus all the other stuff, down a 4 lane link.

I don't think I like intel using PCIe lanes as a product stack differentiator. It means we're still going to need PLX chips for 3/4way SLI.

Doubling the DMI transfer speed to 8GT is still a solid upgrade over Z97 - it will still enable multiple PCI-E SSD's to be used in conjunction with high speed USB3, SATA3, GbE etc.

I don't think we know conclusively that the DMI 3.0 link is only 4 lanes wide yet - so we may be in for a surprise if this got upgraded to 8 or more lanes.

Woot - more benchmark reuslts! Found these posted on Anandtech, credit to the poster there for spotting them:

Sisoft Sandra:
6700K - http://www.sisoftware.eu/rank2011d/show_run.php?q=c2ffcee889e8d5e0d5e0d8efdbfd8fb282a4c1a499a98ffcc1f9&l=en
4790K - http://www.sisoftware.eu/rank2011d/show_run.php?q=c2ffcee889e8d5e0d5ecd8e8dcfa88b585a3c6a39eae88fbc6fe&l=en

Core i7 6700K (up to 4.2GHz):
Multi-Media Integer 390,86Mpix/s
Multi-Media Long-int 181,37Mpix/s

Core i7 4790K (up to 4.4GHz)
Multi-Media Integer 328,08Mpix/s
Multi-Media Long-int 144,12Mpix/s

6700K is 19% faster with Multi-Media Integer
6700k is 25.6% faster with Multi-Media Long-int

Perclock results (Individual results section of the links above)

Core i7 6700K: 79,73Mpix/s/GHz
Core i7 4790K: 67,42Mpix/s/GHz

I7 6700K = 18.25% faster per clock.

So, there we have it, another confirmation of the 15% IPC increase - looks like you were wrong, Boomstick

 

[Dave2150]

Is there any indication that 66/6700 K IHS would be soldered ?

Haven't seen anything on this yet. I suspect they won't be soldered though. The lack of a IVR should help temperatures a lot also

 

[Dave2150]

So about 20%, for ivy bridge users an 25% 30% for Sandy Bridge users. That might just be ebough for to upgrade although I'm tempted to wait for Zen and see what that offers first its not like CPU's are becoming increasingly bottlenecked by the latest games.

Depends what your currently using tbh.


As a X58 user, I'm not prepared to wait for Zen/Skylake-E. I'll go with a 6700k and I'll probably keep it for many years. I doubt games will benefit from more than 4 cores for quite a few years again, given how things developed.

 

[Dave2150]

Those numbers are just about high enough to justify an upgrade from SB for me, but ultimately the decision will come down to overclocking potential; really keen to see what people get out of Broadwell, so we have some idea what kind of headroom Intel's 14nm process currently has.

We've seen 4.5ghz on Broadwelll (5775c) so far, though it was with a toasty 1.4V on air. No details of the temperatures etc were given.

 

[Dave2150]

Hopefully by the time Skylake-E arrives, DDR4 should be much cheaper

DDR4 is cheap as chips already - 2400Mhz 16GB kits (2X8GB) are going for £120.
