View Full Version : Worth Waiting for Skylake?
I'm planing to start a new build since it's been five years since I built my current rig and I was wondering: would waiting for the 6th gen Skylake processors be worth it? Also I heard that they're only making it in the watered down S series, is that true?

Broadwell desktops cpus will still be on socket 1150 and skylake should be on 1151. If that helps you make any decisions. I like the idea of having a socket with more to come. Usually intel will keep the same socket for the following "tock" update. If any of this anecdotal opinion is wrong please correct.
Also there was some new xeons released such as http://cpuboss.com/cpu/Intel-Xeon-E5-1428LV3 e5-1428l v3 If you were going to be impulsive i would NOT recommend them if you want some future proofing through the rest of the year. Lots of neutered features/clocks for a couple of extra cores.
Socket 1150 and 1151 won't be interchangeable. There is a 1pin difference between the two which will result in a rearranged pin set. Not to mention they're supposed to run of different chip sets no less.

The best broadwell cpu will be the 5775C and other than the Iris Pro graphics, it's nothing special. Speed is only 3.3ghz, the L4 DRAM was halved to 64MB, L3 was cut to 6MB, and TDP is capped at 65W. Skylake is definitely worth waiting for.

More info:
Skylake is expected to support both DDR4 and DDR3 (will depend on motherboard slots for which you can actually use), will support 20 PCIe 3.0 lanes (Skylake Xeons will support PCIe 4.0) and the performance increase is expected to be similar to the increase of going from a Pentium 4 to a Core 2 (Prescott to Conroe, specifically). Max RAM increased from 32GB to 64GB also. Will also support SATA Express and have a max TDP of 95W.
All of this is likely, but none has been confirmed. As things are looking right now, there will only be 2 Broadwell CPUs (i7-5775C and i5-5675C) that aren't BGA (soldered to the motherboard) and neither are anything to get excited about.
So what's the estimated arrival date for SkyLake? Sounds like nothing else is worth buying between now and then unless you get a good deal on old hardware...

I'm guessing early fall. I believe intel said it would be Q2 2015 which has now begun but things are pretty quiet so I might have to put some stock into the reports that its going to be delayed. I've read in the past that this 14nm process was a "bitch" and well they really don't need to. A 4790k still sells for 340$ even though a FX-8350 sells for half and is a very close competitor in benchmarks (by far a better value) and probably a better performer in boinc or very close again but better value. I think i'll probably end up buying a used 4790k or 8350 when you guys upgrade to skylake and then buy your skylakes a couple years later.

No, I will not sell you my real estate. I'm building a resort up there and the reservations from Kickstarter Backers alone have already proven profitable.
@MindCrime - take a good look at which benchies you reference for the i7 vs AMD's latest. Unfortunately for us, AMD is very close in everything except pure crunching - look at the Physics score of each CPU, that will equate to what BOINC will use. Not to say AMD's are bad, but credits won't be as good as Intel, and you'll burn significantly more watts for the lesser amount of credits. So if you live in an area with high electric cost at all, then the AMD route just isn't a competitive option. If you live in a rural area where electricity is still somewhat inexpensive, the AMD looks better...

What DrPop said. AMD simply doesn't come very close to performing computations as fast and efficiently as Intel...BOINC or not.

And believe it or not, Intel got that capability from HP!

Some underground engineering sample testing seems to be showing Skylake has a 19.2% performance improvement over Haswell, clock for clock. :-o

NICE! It would be great if they are working on some real gains for the desktop area again! :)

I agree, it'd be nice if they could increase my desk top's size with out taking up more space. Time and space bending desk anyone?
Yeah, I just meant that all their focus (rightly so for business reasons) has been on the mobile sector for several years now. We haven't seen any *real* gains since i7 Sandy Bridge territory was covered. They started work on S.B. in 2005, demoed it in 2009, and released i7 S.B. in early 2011.
Be nice if we could see another jump like that, being 4 years later.

Question, I'm looking at a 5960x build with;
Swiftech H240-X CPU Liquid Cooling kit
ASUS X99-Deluxe/USB3.1
G.SKILL Ripjaws 4 series 16GB memory.
This will replace my AMD x6 machine. Crunching and gaming is the key. I know it's pricey so is there any reason to wait for Skylake?
John P. Myers

No. 5960X is better than Skylake, but Skylake will be cheaper. And it may be 6 months before any Skylake availability.
Skylake will still have just 4 cores / 8 threads, right? Even with almost 20% improvement - and we'll have to see how much of that actually materializes - no way it could beat a 5960X with double the cores. What a whomping CPU! :D

And the more recent results are showing only about 3% improvement :mad:

Looks like the final numbers are in. The Skylake 6700K beats a 4790K by 9% at stock speeds specifically on compute alone.
And for how much less power? :)
John P. Myers
08-05-15, 01:38 PM
Definitely uses less power unless you're using the iGPU. Then it uses about the same or a little more. Issue is all the testing i've seen is total system power, which includes an additional 2W from the chipset itself and every test seems to try to max the cores and iGPU, instead of just the cores.

I just ordered a Sager Laptop with a i7-6700k Skylake, they have the CPU's in stock & I should have it in about 3 weeks ... :D ... It's to replace my 9 year old Q6700 Sager Laptop ...
1 Sager NP9778 Special Gaming Laptops
nVIDIA GeForce GTX 980M 256bit w/8.0GB GDDR5 (w/ G-Sync)
Intel® Core™ i7-6700K Skylake (4.0~4.2GHz) w/8M L3 Cache - 4 Cores - 8 Threads
IC Diamond Thermal Compound - CPU + GPU
32GB (4x8GB) DDR4L/2133MHz Dual Channel Memory
256GB Samsung SM951 M.2 PCIe Solid State Drive (up to 930MB/s Write/1170 MB/s Read - 72K IOPS Write/122K Read)
1TB SATA3 6Gb/s 7,200 RPM Hard Drive
Nice laptop! Looking forward to your review.
My Laptop will be delayed until about the end of October, I was alerted by Power Notebooks that several new & improved hardware items will become available the middle of October & at my request I asked them to delay the order on my Laptop until those items would be available. One of the Items is a new nVIDIA GeForce GTX 980 (without the M) version GPU for laptops which would bring the speed of the video card up to par with a desktop GTX 980 or very very close to it anyway. A new & faster Samsung 950 Pro PCIe 3.0 x4 NVMe M.2 SSD Harddrive is also available ... :D
I just didn't want to get the Laptop knowing it was already outdated before I even got it ... :)

Nice! I have a Samsung SM951 NVMe M.2 SSD (http://www.samsung.com/semiconductor/insights/news/14041) (the 950 Pro will look about the same) which gets about 2 GB/s write, but that new 950 Pro with 2.5 GB/s is much nicer :D
I'm holding out for the i7-6700T... looking forward to replacing my old HTPC/Cruncher with something WAY more capable!
So I finally got around to considering my next build thanks to Newegg's persistent holiday emails and I saw that Skylake finally came out not too long ago. So has anyone gotten one yet? Is the price worth it? Should I wait for more versions to come out at better price points? Bla bla bla?

NewEgg got me as too. I was looking at the Skylake but I pulled the trigger on the x99 that I was talking about in the other thread. I went with the 5930k and the x99 Sabertooth. Finished it last night. The prices NewEgg is kicking around are enticing. Not sure on your budget but believe me you'll be happy with the x99 platform. It replaced my AMD t1100.
IDK about the X99, it looks pretty pricey. Not to mention the wattage. I already purchased a 760 Watt PSU so I'm limited by that. I'm planing to put an SLI setup so I'm not sure about loading it much more. I'm debating an i5 6600 or an i7 6700. I don't plan to overclock so I don't think the K series is worth the premium. Or is it?

my main personal rig is i5 3570k 4c4t. Worked out great for a few years now, but as I log more boinc hours I wish it had hyperthreading

Especially with an sli set up. Have at least 6 threads if its a cruncher too.

My current rig is about six years old now. It has an i5 750.

Yeah your psu is going to be running hard with 2 gpu's so limiting the watts on your cpu is understandable. I liked the 2 extra cores on the cpu. The 6 core 5820k is $390.00 at NewEgg but uses more power. It seems your set to run to gpu's on that psu so keeping the watts down looks like the right choice. Getting a new rig is fun and you'll be happy either way you go.

What GPUs do you plan to run?
Even if you don't plan to OC, I would kick in the extra few bucks for the K series. You get a few hundred extra MHz without doing anything, and I'm guessing the K chips are selected on their higher quality.

I plan to get two GTX 960s. The real difference between the K series and the regular one is that the K series CPUs are "Unlocked" meaning you can over clock that B*#ch to your hearts content. The regular ones have little to no overclocking support. I also noticed the K series has a higher power consumption. If it really is the same chip, why is that?

Not only are they unlocked they are usually a higher quality chip. Extreme series and xeons are the top bin, then you get enthusiast i7, i5, then mainstream, low end. Basically the higher performance or cost chip, from Intel, you get a higher quality chip. I believe the k series falls under enthusiast while non k will be mainstream. IMO its slightly lower quality but could be the same or negligible.

Looks like the Skylake CPUs only support 16 PCIe lanes? Probably not an issue if you plan to run 2 GTX 750Ti's, but could impact GPU app performance on multiple GTX 980's/Titans/Tahitis on some projects like Einstein. No worse than than a i7-3770, but bummer for a new chip.
