Not ideal.

I'm more annoyed about the effort to replace the motherboard rather than the cost. :p
Haha. I feel your pain. Frankly, I hope there's a good reason for this, even though if memory serves, Intel almost always release new cpus with new chipsets. Power delivery is definitely a compelling reason for such a change.

I'm wondering if the more properly thought out Z390 will support IceLake. If so, win! If not, boo hoos.

Edit, oops.

You mean Z390? Nah, the entire 300 series have one CPU family and that's CFL, I'm betting. I'm sure there'll be some sort of abstract reason for ICL to need a 400 and 500 series, both shared with its successor.

I'd put it at 50/50. If CFL uses a new socket (which I haven't seen info about) then it'll probably work with IceLake, if we don't get a new socket till Icelake, then it'll be a one off. Which is unfortunate. I've usually skipped sockets that are only good for one generation because I typically upgrade my CPU at a later date. Of course, in the land of incremental updates - that may not matter anymore.

We indeed heard very little about this new socket. Then again, what is there say other than the number of pins?

Yep, you can pick a CPU and be happy with it for a long time.

"No,Coffee Lake CPU is not compatibilble with 200 series motherboards."

ASRock's Twitter posts have just been removed.
"In previous leaks, we confirmed that their would be a new socket known as LGA 1151 V2 which is pretty much the same thing but has a slightly different electrical pin configuration. This means that current LGA 1151 socket boards are not able to support Coffee Lake chips and the same would be true for 6th and 7th generation CPU support on the upcoming 300-series platform which is built entirely for Coffee Lake processors."

Intel didn't like the negative press covfefe (bad meme)

The compatibility mystery deepens (although no effect on me).

Rumor: Intel's next-generation Coffee Lake Core i3-8300 packs 4C/8T at 4 GHz



http://bbs.ngacn.cc/read.php?tid=12156869&page=3

Double the amount of cores/threads of the current Core i3 lineup if true (at least higher end models). That's Core i7-6700K level performance. Also indicates Intel expects Core i5-8400 to perform better (6C/6T @ 3.8-4.0 GHz Turbo).

Edit: Grain of salt required, could be fake

Intel's next-generation Coffee Lake Core i3-8300 packs 4C/8T at 4 GHz
A new i3, with 4C/8T, and 4.00Ghz stock? Sign me up, well, if the price is $140 or less. Sounds like a decent chip, if you don't care about forward-thinking plans (otherwise, get a Ryzen 7 1700.)

I mean, AMD's closest competitor, the Ryzen 5 1400, with 4C/8T, and not as high a clock speed, is like $155-170.

If this i3 could come in at $140 or less, then we may have an AMD / Intel mid-range CPU price war on our hands, folks.

Plus, this i3 would really rock for 1080P @ 60FPS gaming rigs, way more so than the G4560. Although, it will probably still be twice the price of the G4560, and not be a drop-in replacement, which I think is a mistake.

Maybe Intel and their OEMs and mobo vendors, just didn't want the added verification expense of insuring a proper upgrade ability of existing Socket 1151 boards, to CFL-S.

Edit: I'm going to go out on a limb here, and predict that these new CFL-S i3 CPUs, WILL NOT have "Turbo", that will remain an i5/i7/i9(?) feature.

I'm also going to predict that if the higher-end i3 CPUs are 4C/4T, then either the lower-end i3 CPUs, will be 4C/4T, and there's a very good chance we will see some 4C/4T Pentium CPUs, and possibly even some 2C/4T Celeron CPUs.

IMHO, "dual-core" (without HyperThreading), is dead, for modern games and applications and OSes. CFL-S should cement that.

If this is true, Core i7 7700 users (me) will feel very bad.

That doesn't make sense. 4c/8t CPU will probably have the same (very similar) performance as 6c/6t i5 in both ST and MT tasks. So why on earth would someone buy i5 if it has the same perfromance as $50-$100 cheaper i3. It would be a shot in the leg, unless it's priced the same.

If there is i3 in 4c/4t configuration though, there might be more people who would go for more expensive i5. But majority of users would still go for i3, since it would be great for everyday use, gaming and some business tasks (just like i5 is today), and they would end up in similar situation as it is now with G4560, which outsells all i3 SKUs combined

I really don't believe an i3 will be 4c/8t. Makes no sense at all. How would they then market the i5?

i3 = 4c
i5 = 6c or 4c/8t
i7 = 6c/12t

I'm pretty sure Intel does not want to do this.

There is a difference though. In an application/code with lots of parallelism, Hyperthreading gain is 1.3x. 6 cores would be 1.4-1.5x. So there would still be a difference, just much smaller than 2C/4T vs 4C/4T. And the i5 will have Turbo.

Worse, because the biggest gains for applications are still in the 2C/4T - 4C/4T range. Core i3 would suffice for everything.

Edit: I'm going to go out on a limb here, and predict that these new CFL-S i3 CPUs, WILL NOT have "Turbo", that will remain an i5/i7/i9(?) feature.
Yea, it makes sense. Otherwise it'll be too close.

What they can do it raise prices somewhat. Because people would justify Core i3 is THE chip to get, it would increase their ASPs.

Core i3 7100 - $117
Core i3 7300 - $138-147
Core i3 7320 - $149-157
Core i5 7400 - $182

They can do this:

Core i3 8300 - $155
Core i3 8320 - $165
Core i5 8400 - $182

Or, they can get rid of the 8320, and price the 8300 at $162. I think the i3 8100 would still be 4C 4T and be priced at the $11x range.

What I'd like to see.

Core i3 9100 - $167

Updated roadmaps out guys! Some interesting tidbits I got (first look):

Intel 2017-2018 DT Roadmaps









http://bbs.pceva.com.cn/thread-140322-1-1.html


- There will be 6 consumer Coffee Lake-S SKUs at launch (including both 4C+GT2 and 6C+GT2), we already know the specs for four of them - considering the 6C+GT2 die covers both Core i5 and Core i7 lineup, two Core i3 models make sense, both should be 4C+GT2 (Core i3-8300 above and another one?)
- Production window for CFL-S 4+2 and 6+2 is the same, ww34-41 2017 - which means August 21 to October 9
- Up to 24 PCIe 3.0 lanes
- 95W (enthusiasts), 65W (corporate / mainstream) and 35W (low power) TDP SKUs, as expected
- KBL-R PCH = Z370 = high-end chipset, which launches first and apparently won't get replaced by a Z390 in early 2018 as Dr.MOLA indicated
- CNL PCH = Rest of the 300 series, including programmable quad-core audio DSP, Gen 2 of USB 3.1, Wifi-AC, SDXC 3.0 and Thunderbolt with DisplayPort 1.4 - even H110 will be replaced

That's a very feature rich chipset. It looks awesome. Integrated Wireless**, updated USB 3.1 standard, better audio controller, Integrated SD card controller, support for Next Gen Optane Memory*

*It seems extremely early considering. Are they going to introduce next gen Optane Memory 6 months after the first one? Or is it going to be like first one where chipsets came months before the sticks? I guess it can work if they feel the first one didn't work out for them. Low power idle mode and support for caching on a secondary drive would be great. Along with increased capacities and throughput.

**The WiFi functionality needs a CRF(Companion RF) chip. From the Wireless AC 9560 datasheet: https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/dual-band-wireless-ac-9560-brief.pdf

The Intel® Wireless-AC 9560 adapter is a CRF(companion RF module) supporting the 1st generation integrated Intel wreless 802.11ac solution comprised of CNVi3 and a CRF
Footnote about CNVi says:
CNVi; Refers to the integrated wireless IP portion residing in the SOC/PC
So partial wireless functionality. That means decreased cost on the "card" side. That's great.

Integrated SD card controller means additional BoM reduction. I hope the "quad core audio DSP" is an IA core variant! Time to ditch ARM there, they are already doing that on some other areas.

The leaker (royalk) seems to think CNL PCH also supports future Cannon Lake-S CPUs, but we know this SKU was canned a long time ago. I wonder if he got confused with Ice Lake-S. I speculated about ICL-S compatibility for socket LGA 1151 with CNL PCH back in June.

I was more interested in coffee lake but not interested enough to change my mobo since I just got it last year. On a side note my brother wants a new PC so I could always give him my mobo and get new stuff..I gotta stop buying stuff like this.

Cannonlake is also IMVP9. Yes, I guess he got confused. It's too bad they had so much trouble with both 14nm and 10nm processes. That chipset and 10nm Cannonlake a year ago would have been formidable in the marketplace. 8 core with 40EU Gen 10 GT2 would have been a proper replacement for enthusiast users(K chips) and everyone else.
