Don't know if it's been posted, but..

http://www.overclock.net/t/1568357/skylake-delidded



Some rough measurements assuming the package is 37.5mm*37.5mm as are 1156/1155/1150 CPUs, gives around 120mm^2 for the die.

Lynnfield: 296mm^2
Sandy: 216mm^2
Ivy: 160mm^2
Haswell: 177mm^2

That's tiny, and they're asking $350 in i7 form for that. I guess the 14nm process and additional R&D are getting ridiculously expensive at this point.


Guy is also reporting much better temperatures / higher clocks doing the usual thermal paste change and black adhesive removal after delidding.

Don't forget, at least half of that is the useless for a lot of us IGP. That means we are really paying $350 for a 60mm2 die. :sneaky:

The "higher costs" argument is propagandist BS.

"gross margin of 62.5%" <<< way way higher than Apple's >>>
http://www.intc.com/releasedetail.cfm?ReleaseID=922294

Intel can easily sell us a $299 6-core Skylake-K but they won't because there is little competition. We just have to wait patiently until 5820K's successor shows up for a slight premium.

It's appalling they still keep cheaping out on solder and use $3 TIM:

"Intel fixed the Haswell problem by implementing its Next-Generation Polymer Thermal Interface Material (NGPTIM) on Devil&#8217;s Canyon, which resulted in a temperature decrease of more than 10% in our testing. That still doesn&#8217;t deviate from the point that any form of polymer TIM is, almost certainly, less thermally conductive and effective than the solder that HEDT chips use."

No wonder so many reviewers are hitting 80-90C at full load on even Corsair H100/110 and Noctua NH-D15. For someone planning on running distributed computing, rendering, encoding where the entire CPU will be loaded to 99% for hours at a time, this is a big deal. Skylake-E is bound to follow in the footsteps of HW-E with proper solder.

Interesting, in the games tested by Eurogamer Core i5 6600K (Skylake-S) provided a larger performance per clock performance gain than Core i5 4690K (Haswell) compared to Core i5 2500K (Sandy Bridge).

Core i5 6600K vs Core i5 4690K (same 3.5-3.9GHz base/turbo)
- 17.3% faster @ The Witcher 3
- 11.4% faster @ GTA V
- 10% faster @ Battlefield 4

The turbo is not the same according to some reviewers. Some report that Skylake is able to clock all the cores at maximum boost on certain boards. Since there isn't many Z170 motherboard reviews to know which boards are allowing this, it's hard to make conclusive remarks if the comparison of stock vs. stock Skylake vs. Haswell/IVB/SB is apples-to-apples IPC comparison.

Secondly, you continue to cherry-pick data to suit your viewpoint.

Not all games were tested on Ultra with high levels of AA. Some games were only tested on High and with FXAA. If someone is using a GPU as powerful as Titan X OC at 1080P, they could easily use DSR at 1080P instead of playing Shadow of Mordor at 126.6 on 2500K or 132.7 on a 6600K.

Actually breaking down all of those benchmarks reveals that besides GTA V, that was tested without AA (in other words a useless real world test again), 6600K is not an upgrade for gaming over 2000/3000/4000 series CPUs. That is because in all cases even a stock 2500K is > 60 fps.

It gets even worse since many 2500K/2600K CPUs can do 4.5-4.8Ghz overclocks, 3770K can do 4.5-4.7Ghz too.
http://www.eurogamer.net/articles/digitalfoundry-2015-intel-skylake-core-i5-6600k-review

In other words, what I keep saying is still true:

It's still better to get an even faster GPU, get a 2nd GPU, get a larger SSD, get a better/bigger/more modern FreeSync/GSync monitor rather to upgrade to Skylake. All of those upgrades are more beneficial for gaming. For example upgrading from a 22-24" 1080P monitor to a 27-32" 1440P one is a way better upgrade than moving from SB/IVB/HW to Skylake.

Besides, how many gamers have a 980Ti/Fury X or Titan X level of GPU? For most gamers with 2500K-4790K, unless they already have a GPU that powerful, Skylake upgrade is a waste of $ for gaming; and again showing us a comparison of stock SB/IVB/HW against Skylake isn't a real world scenario for many of us running those CPUs at 4.5Ghz+.

Also, with DX12 gaming, we could start to see even more games start taking advantage of 6-8 cores.

I agree with IDontCare's post but I think I am also on board with waiting for Skylake-E. For a bit more $ than i7-6700K, it'll be 2 more cores that are bound to come in handy. If someone is building a new rig now for school/work and cannot wait for Skylake-E, 6700K is a great choice and of course better than 4790K.

Yea, that deal sounded too good to be true and it was. That was definitely a typo.

Ya, sorry that was a type. Glad you guys caught that.

It's $450 but it doesn't change the main theme. The overall price of X99+5820K vs. Z170 board+6700K could be fairly close at places like MicroCenter. For those gamers who have access to this store, the decision isn't as easy.

Canada had the Asrock X99M for sale for $140 CDN (~$106 USD+tax) for more than a month. 5820K regularly sells for $499 CDN which is just $50 more than 6700K, but since it's been out for so long, it's not hard to find them on Craiglist/Kijiji for $420-430, less than what the i7-6700K costs.

For someone in the US, it's going to be even easier to find 5820K+X99 boards given how long they've been on the market and how competitive US prices are.

This is the ram i got
http://www.newegg.com/Product/Product.aspx?Item=N82E16820233831

Wondering if i should bump it up a little.

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231902

I havent had a chance to go over reviews in details but what i have skimmed over higher frequency memory doesnt seem to make much difference on something like handbrake.

Not sure about a workstation, as for gaming it do make quite a difference, you should at least take the 2666 one if it's a gaming rig.

Umm..... cherry picking data? You mean like those 3 or 4 heavily multi-threaded games you examine in post after post "proving" the superiority of hex cores? I do agree with you though, and I have been saying it for a while, that Intel definitely needs to bring out a mainstream hex core on the most current architecture and platform. They could certainly afford the die space with 14nm and the minimal improvement from generation to generation shows they have pretty much wrung all they can out of quad cores.

I rarely do any gaming. Last 2 games i played was command and conquer Tiberium Wars and a little bit of Resident Evil Revelations. I might do some gaming if i find something i can get into. Ill see whats available while waiting for the darn cpu

The "higher costs" argument is propagandist BS.

So is purely equating die area with total cost. Patterning 14nm features with 192nm light is easy right? Doesn't increase cost at all... right?

For those of us that are terrified to delid, is there any risk of the TIM drying out over time? I usually like to keep a build for 3-5 years or longer now that IPC improvements are basically stagnant and the cheap paste worries me a bit.D:

Since there isn't many Z170 motherboard reviews to know which boards are allowing this, it's hard to make conclusive remarks if the comparison of stock vs. stock Skylake vs. Haswell/IVB/SB is apples-to-apples IPC comparison.

If that was the case Digital Foundry would most certainly mention it, mostly because it would not represent what a 'stock' Core i5 6600K delivers, so basically you're just guessing without any concrete evidence. And it's not hard to make conclusions about performance per clock, Hardware.fr did test them at a fixed 4GHz and Skylake was 12% faster than Haswell and 23.8% faster than Sandy Bridge (overall from 8 games).

Secondly, you continue to cherry-pick data to suit your viewpoint.

Yesterday you accused me of using low-resolution 640x480 benchmarks to prove Skylake is faster. We have at least 3 reviews now (Hardware.fr, Eurogamer and Hardware Canucks) where Skylake manages to outperform Haswell by the usual Intel tock margin in some of the latest CPU intensive games at 1080p. If that's cherry picking then the 3-4 game list you vomit in all posts to prove Haswell-E is better for games is what? Lol.

Not all games were tested on Ultra with high levels of AA. Some games were only tested on High and with FXAA.

You mean Skylake won't be faster than Haswell in GPU-limited situations? What a shocker, who would have guessed.

Actually breaking down all of those benchmarks reveals that besides GTA V, that was tested without AA (in other words a useless real world test again), 6600K is not an upgrade for gaming over 2000/3000/4000 series CPUs. That is because in all cases even a stock 2500K is > 60 fps.

What did you say again? Oh yes, even when OCed Core i5 2500K will barely match a stock Core i5 6600K in CPU-intensive games, and that's before Skylake overclocking comes in.

Eurogamer
Core i5 6600K vs Core i5 2500K (3.5-3.9GHz vs 3.3-3.7GHz base/turbo)
- 25.8% faster @ The Witcher 3
- 31,7% faster @ GTA V
- 25% faster @ Battlefield 4

Hardware.fr
- 44.1% faster @ Crysis 3
- 40% faster @ X-Plane 10
- 28.8% faster @ Arma III

It gets even worse since many 2500K/2600K CPUs can do 4.5-4.8Ghz overclocks, 3770K can do 4.5-4.7Ghz too.

So does Skylake, Eurogamer managed 4.5GHz out of their Core i5 6600K sample. Difference will be lower but it's still there.

In other words, what I keep saying is still true:

It's still better to get an even faster GPU, get a 2nd GPU, get a larger SSD, get a better/bigger/more modern FreeSync/GSync monitor rather to upgrade to Skylake. All of those upgrades are more beneficial for gaming. For example upgrading from a 22-24" 1080P monitor to a 27-32" 1440P one is a way better upgrade than moving from SB/IVB/HW to Skylake.

I mostly agree with this, but there are situations where the improved IPC does help improve the gaming experience. Also for the second time, some people simply want to upgrade, even if that doesn't make 100% sense from an economical POV considering the actual benefits. I personally love buying new high-end GPUs even though I still use a 60 Hz 1080p monitor. And don't forget framerates don't tell the whole story.

Per Intel (IIRC), cost/mm^2 normalized for yields at 14nm are ~30% greater than 22nm. This means that from a cost perspective, the 120mm^2 Skylake is akin to a ~156mm^2 22nm part if yields were equivalent.

Haswell 4C/GT2 is 177mm^2, so once 14nm matures it should be slightly cheaper to make than a Haswell 4C/GT2.

Intel has to be smart. Apple and Samsung "could" sell their flagship phone devices for $400 instead of $700. The profit margins on those are pretty substantial.

Intel needs their server revenue. The desktop is dead.. they can't afford to be giving out 6-8 core parts for a small group of people who represent a small amount of their revenue when it could take a big bite out of their higher priced server parts.

Yeah I wish they had 8 core parts for $500 but I can see why they don't. It's not smart business.

Those charts above are a bit misleading. Crank the 2600K up to 4.5 GHZ instead of it's stock settings and repeat the test. I admit I'm tempted by an upgrade even though I don't need one. If that 6700k had a soldered IHS I might just bite.

It's not misleading to compare stock configurations. There was nothing mentioned about an overclocked parts comparison. If you are going to clock the 2600k to 4.5Ghz you may as well clock the 6700k to 4.5 and compare too.

What i would have really like to see is some benchmark at the same clock of 5820k vs 6700k

I've been reading reviews for the last hour.

I'm going to have to say I'm disappointed. I'll be staying on Lynnfield, the longest I've stayed comfortably on a system.

Intel Skylake / Z170 Rapid Storage Technology Tested - PCIe and SATA RAID *updated*



]The takeaway here is that PCIe RAID is here! There are a few tricks to getting it running, and it may be a bit buggy for the first few BIOS revisions from motherboard makers, but it is a feature that is more than welcome and works reasonably well considering the complications Intel would have had to overcome to get all of this to perform as well as it does. So long as you are aware of the 3.5 GB/sec hard limit of DMI 3.0, and realize that 4K performance may not scale like it used to with SATA devices, you'll still be getting better performance than you can with any single PCIe SSD to date!

If you are talking about the default TIM, I'm pretty sure that stuff is going to last for the life of the CPU.

If you asking about user-applied TIM post delid, welllll that's another story, though pump-out is the greater risk there.

Is desktop dies, PC gaming dies too. And with that the beginning of a Gaming crash happens since Mobile is a pretty inmature industry and console one are slowly dying. Unless a new tech appears to revive some industries, at best we might get Core i7 Hexa Cores on Cannon Lake.

I don't think the Intel TIM is "cheap paste," exactly, but it is a compromise that we as enthusiasts can't help but hate. Certainly it is designed with good longevity over many heating and cooling cycles. I haven't noticed any significant degradation in thermal performance of my 4790K in the time I've owned it. Given the decent OC figures most reviewers have posted with SKL, it would not surprise me if the unlocked versions use the improved TIM that debuted with Devil's Canyon.

that is not true
6700k has only GT2 graphics, which occupies only 30-40mm^2

that is 40% or more of the die, we could have 2-4 more cores at the same die area, meaning sub $300 6 core or sub $400 8-Core CPUs.
