"i5" is just a name. What you're asking is whether we can get new 8 core Intel chips for the price of an i5, to which the answer is obviously no wink.gif

The 6 core Coffeelake (2018) is for laptops on a further improved 14nm+ and comes with 128MB L4 like the 5775C 6MB L3 / i7-6785R 8MB L3

http://www.fool.com/investing/2016/08/19/intel-corporations-kaby-lake-for-desktops-looks-li.aspx
"The first such derivative technology that Intel is announcing (or, at the very least, bothering to brand for investors' sake) is 14+. This is a technology that includes enhancements to both the transistor as well as the metal stack to yield a performance improvement of 12%."


http://www.guru3d.com/articles-pages/core-i7-6950x-6900k-6850k-and-6800k-processor-review,10.html
33.95 stock and 3.2ghz ram vs 34.64 stock and 3.2ghz ram or 40.74 at 4.8ghz and 3.2ghz ram vs 44.01 at 4.32ghz and 3.2ghz ram
Another site shows 4ghz vs 3ghz gained 22% in handbrake with faster ram. Perhaps a 4C/8T Kabylake can match a 6C/12T Zen in multithreaded apps if core, ram, and IPC are lower?

My current Asus Z170 VIII Ranger has RAM timing problems where it takes good 20 seconds to boot if I use XMP RAM profile. It also has that I219-V intel ethernet which makes Windows download and install an old ethernet driver and overrides any newer driver I install.

Can't wait to sell this board ASAP.

Am I the only one who is interested to shove my i7 6700K into new Z270 motherboard? I have zero interest in this Kabycrap CPUs.

I agree with you on this. Skylakes hit 4.2Ghz boost on 1 core, but in reality 4.6Ghz is like 99% guaranteed on 4 cores. They could hit 4.4Ghz base 4.6 boost with losing less than 1% of their yield, and from what i gather the silicon is pretty cheap once the fab is running anyways.

I also doubt intel is having stock issues so i don't think it'd hurt them to run a fab more. Silicon is the cheap part, the fab isn't.

There is certain stuff called wearing out of CPUs. Intel don't wanna degrade theirs CPUs by overclocking, and Intel doesn't like to distribute high end heatsinks with theirs CPUs. In fact, one of Intel's advantages is energy efficiency in comparison to AMD.

Intel clocked 4790K close to the limit, and it caused problems. Actually it caused massive problems, when normal users used normal heatsinks for non OC work. High end overclockers delided and didn't notice, but when you look at HW seller pages, and forums, you'd see lot of posts when users received CPU that had problem on normal clocks.

Headroom is there to ensure durability. Removing headroom would only cause problem to end user, and to Intel. Intel is trying to reduce durability problems by using certain internal stuff on SKY, to ensure longer durability by playing with power. But playing it dangerous might hurt Intel's sales and Intel's reputation.

Frankly when Intel would use full headroom, I'd do underclocking.

I'm definitely waiting for Zen, but these intel chips look tasty. Any word on a release date?

Same here, win win situation. If Zen is good intel will need to lower prices. If not it may be worth it to build Zen because of price/perf.

I wonder if Intel doesn't count on "i7-7700K has highest FPS" theory.

Folks if i7-7700K has turbo up to 4.5 GHz, then how would look like KB-X?


Actually these names are giving me headashes for the same reason as when Rorona met Gil, she said "I'm troubled, I can't shorten his name." (Too bad PS3 Atelier games were not released on PC as freeware.) Shortening kabbylake is trouble. Nearly nothing sounds right. SKY was easy.

Now I can ask a question to myself: Upgrade from 4790K devil's canyon (4,7 OC) or still wait?

Arggghhh!!
