Well, we don’t know when the 8 core chip drops yet or even whether it is 14nm++ or 10nm+ for sure yet. We are still waiting. Intel probably isn’t going to say with certainty because it doesn’t want to lose hexacore sales.

14nm++ part would be lower risk in terms of both yields & potential Fmax. The issues that Intel is facing with 10nm really are quite bad.

The downside of having to perfect their current node for longer periods of time while also struggling to develop the next is double the trouble: it means the next node needs to become efficient enough not only to be production worthy, but also to beat a thoroughly perfected previous iteration.

If Intel has been unable to make significant improvements to 10nm yields under the 10nm+ process node; then Intel is in trouble period. Maybe this is why Ashraf Eassa thinks that Intel should be planning a fourth 10nm node. Maybe that node should use EUV, since it seems that SAQP is killing Intel.

Intel definitely seems to have had an issue with moving aggressively to new lithography techniques.

Remember with 22nm, which is probably the last "drama-free" node from Intel, Mark Bohr was talking about how the min metal pitch of 80nm was chosen specifically because it allowed Intel to avoid the hassle of double patterning the densest metal layers.

It was when Intel got it into their minds that they needed to leap ahead and "beat" the rest of the industry to new denser nodes, they started being much more aggressive with the lithography -- SADP at 14nm and SAQP at 10nm.

Had this worked out (and I suspect Intel had a lot of confidence in its ability to get this done), then they could very well have been as far ahead of the rest of the industry that they say they are. But it clearly didn't.

Intel may have been better served by iterating less aggressively with each generation but being able to make more iterations within a certain span of time.

Anyway, whatever Intel is doing just isn't working properly and it's ultimately hurting its ability to release cool new products on time. The moves they did with KBL/KBL Refresh/CFL are certainly nice, but with good planning ahead of time, Intel could've done better in terms of advancing its architectures and processes.

Unlike many of the 'FABs' 1/2 nodes, Intel's 10nm is more aggressive vis-a-vis metal and contacted gate pitches. I guess Intel played a game of win or go home. At the moment, they would be screwed if they were not already ahead of the pure fabs @ 14nm. If Intel is really planning 8 cores at 14nm, then it just to be able to get solid quad cores w/iGPU out at 10+ (maybe a hexacore?). Sad news, so much for promoting a guy to CEO with allot of manufacturing background.

intel has announced official prices, specs and turbo clocks:

https://www.anandtech.com/show/1186...ation-coffee-lake-hex-core-desktop-processors

https://arstechnica.com/gadgets/2017/09/intel-coffee-lake-price-specs-release-date/

The 8700 non-K looks very attractive to me since I'm not interested in overclocking:

Turbo clock = 4.6 GHz, vs. 4.5 GHz for the 7700K, only 100 MHz less than the 8700K . Price per 1,000 is the same, $56 less than the 8700K. TDP is 65 watts!

That should mean no need to delid, and a 120mm air cooler should run silent at idle, quiet under load.

Doesn't a lower TDP mean it will be more likely to throttle down to base clocks during heavy use due to power limits? I wonder if the 8700 can maintain it's turbo clocks while all cores are at full load with the 65W TDP or if there is a lower power limit on the 8700 than the 8700k. I wonder if even 95W TDP is enough for the 8700k to maintain it's turbo clocks while all cores fully loaded.

I hope that CFL isn't like P4 Prescott (PressHOT). That one had so many issues throttling at stock, that they invented BTX form-factor, and the direct side inlet air-duct.

That's possible, we'll have to wait for real-world benchmarks to see. I don't care about CPU-burner benchmarks though, just real gaming ones.

The 7700 non-K does use 10-20 watts less under load than the K in the benchmarks I've seen, and there are allegedly some improvements in Coffee over Kaby.

They posted it in the correct thread mate. The reviews one.

Thanks though.

I cannot believe that there are those who are complaining about board compatibility for 20 odd pages! If you're not happy with that fact buy something else. There are far more important things in life and this certainly won't kill you, jeez.

I could care less for socket compatibility since almost all my mobos never went above the $100 mark, besides what is ~$100 for a new mobo every 3 years?

I hear you. You would think that socket compatibility would be the number one priority amongst users judging by the amount of posts and complaints on this issue.

Personally I always upgrade my motherboard when I do a CPU upgrade too, because I only upgrade my CPU once every few years.

I then sell off my old CPU and motherboard to recoup some of the cost of the new platform.

It's not only about using your old motherboard, it's also about availability, pricing, and the flexibility that comes with being able to buy previous gen hardware at very good prices.

For example, instead of buying a brand new Z370 board I could buy a more budget oriented board for my i5 and use my perfectly good premium Z board in a new Coffee Lake build. Another option would be to buy a proven Z270 board if the new Z370 boards were significantly more expensive.

And that's why the motherboard makers wouldn't want Intel to keep compatibility of Kaby Lake with 300-series boards

I don't know about you, but I'm on my 3rd CPU in the same motherboard. It's not just a new motherboard either, since you need a new Windows license if you change motherboards. Yet another expense.

IIRC, if you tie your windows license to your MS login it can follow you from build to build provided you aren’t using the same key on multiple builds simultaneously.

And it doesn't even require you to do actually manually tie them I believe? Let me know if I'm wrong so I can get that done this weekend.
