Intel Skylake / Kaby Lake

[Arachnotronic]

Actually, Justinbaileyman, you can do this cheaper than what I had above...no need for the super highly clocked RAM:

I recommend x99, esp. if you're going to use the system for a long time (3+ years) because at some point you'll be able to pick up really cheap, used Xeons on eBay that could give you a viable and cost-effective upgrade path to 8+ cores. This gives the x99 platform far more longevity (at least in theory) than the mainstream ones where it's four cores or bust.

 

[alcoholbob]

Because 5820K is not Skylake ??

Plus I would expect the new Skylake platform to be basically just an evolution of 115X which should be pretty stable.

A lot of X99 motherboards seem to have chipset issues. I tried building an X99 system earlier, went through 3 different motherboard brands (Asus X99 Deluxe, MSI, and a Gigabyte) and not a single one of them would post with any USB devices attached. Seems like the X99 chipset has something wonky going on with USB post if you check newegg reviews alot of X99 mobos have this issue where motherboards just go into endless reboots during post with any USB devices attached, so I just ended up building a 4790K system. If I can't post with any USB devices I can't get into the BIOS so I'm stuck with a 3.3GHz chip I can't overclock--I'm better off with a 4790K.

Not to mention the 6700K will be a 15% speed boost across the board compared to a 4790K. A 5820K is only faster than a 4790K in very specific benchmarks. In many desktop apps and games the 4790K would still be faster than the 5820K.

Going from an Athlon 750K @ 5GHz to Core i7 4c/8t Skylake @ 4GHz will be massive increase of performance for your workload.

Edit: Power consumption vs the 5820K with 4x4 dimms will also be massive

I know it!! I was looking at the i7-4790k at stock vs 760K@5.0Ghz and the 4790K is almost 3 times faster at stock. I am betting it would break 3.5 times faster after being overclocked to 4.5Ghz.Dont know why I was so bull headed to go Intel before but now I just cant stay with AMD and this 760K its just to slow for what I do.I did have a L5639 for the longest time and was a very strong cpu just kinda slow at some things with the older instruction sets. So I am looking for new new new everything and its going to have to last 2-3 years till next upgrade.Also dont need cooling I have a sealed water cooling setup with a 140mm rad from NZXT.

weak sauce. For those who are on haswell, pass except if you need the platform goodies. Everyone else maybe relevant unless you find a low price haswell.

? If you're on non-DC Haswell, you're seeing a 30% jump in performance, not even accounting for room for overclocking.

 

[rickxross]

If u want hexcore now look at used xeon x5650s.

You can get them for ~80 bucks on ebay, lots of companies upgrading their servers and tossing them.

I got one and oced it to 3.8ghz.

Not exactly new, but 6c/12t for pretty cheap.

 

[Justinbaileyman]

X5650 instruction sets are to old for me and pretty sure I mentioned earlier having an L5639 which is the low power TDP version of the x5650 clocked at 2.0Ghz but I had mine overclocked to 3.6Ghz.I got rid of it for a AMD 760K which I thought would be better due to it being newer with newer instruction sets but not really.

As far as the stats go I only found one of yhe the links for 6700k vs 4770k comparable as they have the most consistent variable (the benchmark result from atech
Is cinebench 11 and the other 6700k link is just cinebench).

There we can see a 23% increase in performance. Dollar to dollar the cost of creating a system would not Justify the additional cost of platform costs. Again ill give u the
Tock is solid compared to the previous jumps, however it's better to get in with a DC then jump into a skylake

 

[Justinbaileyman]

Holy crap 23% increase.. Thats huge in my book. Just that much could shave off an extra 15-20 mins of encoding/converting time for me. Keep talking it up just makes my mouth water more LOL.Skylake-K's cant get here soon enough in my eye's.I would go 4790K but I am wanting to go DDR4 for future proofing needs.That DDR4 2400 16GB kit from crucial for only $160 is a steal maybe I should grab that now before the price goes up.

Sure, everyone will have to make their own judgments on whether it is worth the upgrade for them. It would largely depend on your use. I just thought "weak sauce" an odd remark for what looks like a very solid performance increase. And you if you can overclock the 6700k to 4.5 or above. . .

 

[Blue_Max]

Maybe I'll hold out for the new CPU + socket before building the ITX rig I'm just itching to make!

 

[B-Riz]

I am curious on how / if Skylake will improve minimum and average FPS / frame time for all the games out there...

True, however looking at it further (ala I was on mobile now on desktop), I wanted to dig up this excellent article. And This is what I was referring to when I said weak sauce.

^ in case we need to update the Cinebench results


the bump when sandy came to the mainstream platform was significant.

In regards to the initial post, theyre claiming:
Core i7 6700K is:
30,5% faster than Core i7 4770K.
38,4% faster than Core i7 3770K.
50,85% faster than Core i7 2700K.
86% faster than Core i7 965.

However the Atech article shows the Cinebench test (11.5) vs Cinebench test (15) has interesting results when combined and also not accounting for different cinebench setups.

i7 6700K results:10.53
i7 4790k results: 9.23
i7 4770k results: 8.07
i7 3770k results: 7.61
i 2700k results: 6.98
i7 965x results: 5.66

Their is change however again nothing out of the ordinary. Plus it seems like broadwell has not hit the market yet. Are those chips going to be primarily non K and the transition will be from DC haswell to Skylake-K? if it isnt the performance advantage will further drop.

I`m not trying to bash Skylake. However the CPU is not what Skylake is made out to be. Its the platform as a whole that will usher in a new era of computing. As this is the maintstream offering from Intel, the features will drive sales here. The feature set is an extensive revision in itself.

That's why you need to look for the exact same setup and same testing sites for comparison. Few % variation between sites exist.

Also the 6700K results are pre-release samples. You can see even between initial 4770K AT benchmarks and Bench numbers that it improved too and same with 5820K. We'll only see with final retail samples that it stays at 10.5 points or goes to 11 points and have the same 30% gap to the 4770K.

Looking at the agressivelly clocked 35W ''T'' desktop quad-cores I'm quite optimistic about the mobile lineup. Honestly there's no place for 37W dual-cores anymore. I expect:

- High-clocked Y / U 4.5-15W dual-cores with GT2, GT3e graphics.
- Few or no 37W dual-cores. Wide range of 37W quads, fewer 47W GT2 models than Haswell.
- GT3e becomes more mainstream, especially for quad-cores.
- High-end 47W+ quad-cores with GT4e graphics, hopefully at sane prices.
- Maybe its time for a 28W mobile quad-core.

We already know from leaks that:
-Y/Us are up to GT3. Recent leaks indicate "Iris" class(not Iris Pro) for 15W variants. So we can deduct Y only have GT2
-There are no 37W dual cores. The difference to a 28W one is too small
-28W is known as 2+3e, which means dual core Iris Pro

Skylake 4C+GT4e could be available in early 2016.

Three things are possible:
-Only Xeon E3s are getting Skylake GT4e chips. This means Xeon E3 v4 aka Broadwell with Iris Pro P6300 is being cancelled. No confirmation yet. That means this is less likely.
-Broadwell GT3e for mobile not being released. Possible.
-Broadwell GT3e mobile relegated to lower end and Skylake GT3e mobile at the highest end. This makes the least sense.
-Most likely: It's just a nonsense rumor and Skylake GT4e mobile is for Q4 2016.

Financially it makes zero sense to cannabilize their own product lines. You can't have Broadwell GT3e and Skylake GT4e being released at the same time. One's not coming.

 

[jpiniero]

You can't have Broadwell GT3e and Skylake GT4e being released at the same time.

I don't think there's been any suggestion that is happening. Broadwell 4+3e is coming in June; Skylake 4+4e sometime in Q1 2016.

Which leaks? I'm basing my expectations on this:

According to it 15W Skylake-U will have both GT2 and GT3e versions. That's right, Iris Pro. There's no sign of 35-45W dual-cores yet, I hope they restrict dual-cores to Y/U SKUs.

Where did you see GT3e Xeon E3 v4?
They won't be released at the same time, desktop GT3e Broadwell-K will be out by June in LGA form, that won't stop them from launching a workstation BGA-only GT4e Xeon E3 v5 in early 2016 if it's available by then.
They could very well limit the number of Xeon E3 v4 SKUs and focus on Xeon E3 v5, just like they did in desktops with Broadwell-K and Skylake.

Right. Recently they said "Iris" for 15W, which suggests non-e but I guess they can always designate "Iris" for e models too just with higher model. Say, Iris 7100 for 15W GT3 and Iris 7300 for 15W GT3e.

You missed what I said again. Iris Pro P6300.

They are not going to launch two replacement models within 9 months of each other. OEMs complained before about 12 month launch being too short, let alone 9. It's simply not happening. ~12 months is the optimum time for squeezing out every dollar and not making the product stagnant.

That's only true if the intend to launch a GT3e Xeon E3 v4. They could very well release a limited number of Xeon E3 v4 SKUs given that Xeon E3 v5 is not that far from launch by now.

Just because workstations will receive a BGA-only 4C+GT4e Skylake in Q1-2016 it doesn't mean desktops and mobile will get the same treatment, they might not replace 4C+GT3e Broadwell there till mid-2016.

Yes, Iris Pro P6300. What do you think the "P" stands for? Obviously its the Broadwell generation. Also the link points out GT3e Broadwell.

http://www.cpu-world.com/news_2014/...s_of_Intel_Xeon_E3-1200_v4_v5_processors.html

Actually the CPU-World does seem to clarify what Intel might be doing. BGA Xeon? What the heck?

The same article mentions Intel will introduce GT4e Xeon E3 v5 at the beggining of 2016. Strange but not impossible. Note that GT2 versions of Xeon E3 v4 might be replaced by GT2 Xeon E3 v5 after a shorter amount of time than the Iris Pro variants we're talking about.

I still think they will limit the number of v4 models to avoid such a mess.

Ugh this is frustrating. Just as I was finally dialing in on building my 5820k/x99 rig, these benches leak and f* everything all up. HEDT being 1-2 generations behind is really getting on my nerves. I want more than 4 cores but with this Skylake performance increase it makes it moot..AGGHGSKFjbdsKHFA!

Behind what and a performance increase in one benchmark? What about real world usage? Will Skylake magically give you 10FPS+ in GTA V? Will it encode x264 15min faster than a 4770K?

The leap-frogging certainly does make it more difficult for a consumer to feel like they've successfully bought cutting edge tech in too many ways at the same time. I agree with you, it is a bit disappointing and frustrating all at the same time.

On the flip side though, the reason this happens in the industry is because it lowers cost, which means it ultimately results in a lower purchase price. So you can take some solace in that. Were all the next-gen hardware stars aligned such that you could get the best of everything or anything all at once then your purchase price would be significantly inflated for each of those items.

HEDT is 1-2 generations behind the mainstream desktop cores. Its 1 generation now with broadwell, and will be 2 generations behind when skylake drops.

I dont care about games, I care about the performance in Adobe Premiere Pro/After Effects/Encoding/decoding/editing video etc etc. Cinebench is a good indicator of MT performance, which is what I need.
