Of course they will. Intel is selling quad cores on X299. You think they'll let you have PCIe lanes on 6-cores?

Thanks AMD! I hope I can use the 6 core on my Asus z270i Strix. If I have to buy another mobo then I'll just upgrade to a Ryzen system instead. tongue.gif

Coffee Lake is a new platform, Z370. Gotta buy a whole new system. So CL new build, Ryzen and drop in Ryzen+ and Ryzen2 and Ryzen 3 when you feel like it(on the same board thanks AMD) or go SLX with the gimped 78XX witht the same I/O as CL(lol).

the 6c 6t unlocked chip I don't see who would want to get that when there are other options

It'd be the 2500k of coffee lake, such cpu's have been extremely popular in the past

and the 6c12t is going to be fighting against the LGA 2066 hex and Ryzen 5 at the same time.

Ryzen 5 isn't much competition when the MT perf is trading blows w/ ryzen 7 8c16t and ST perf is way ahead of everything ryzen

Need it to be able to hit 4.5GHz + all core for the 6 thread parts unless there's a double digit improvement in IPC over Kaby Lake.

i5-8600K or i7-8700k could be worthwhile purchases if there's overclocking headroom. ~ +11% like Kaby Lake would not be impressive (4.5GHz -- 5GHz is ~ 11%).

The locked i5-8400 is likely dead on arrival since 2.8GHz is a really low locked base clock.

Incredibly happy for x299 users that were planning on getting a i7-7800X though.

I believe as far as pricing goes it'll likely be $350 for the i7s and $250 for the i5s , so it comes down to motherboard cost.

btw, unlike X299 that caught pants down by threadripper. These chips is most likely a planned release, Intel probably has this chip ready for Zen. (since Zen has been make known to feature 8 core long long time ago, so I guess Intel has planned this chip to complete against it)

Actually, most rumours out yesterday suggest it is compatible with Z270 and some Z170 chipsets.

4 / 6 * 95W is approximately 64W ( 63.3333 )

A Xeon E3-1280 V5 ( A top binned Skylake ) runs at 3.7ghz using 80W. A lower binned 14nm++ quad core can run at 3.7ghz using only 64W.

A Xeon equivalent of the E3-1280 should clock a little higher with the same voltage at 64 TDP. 3.9ghz 64W 4C/8T Xeon?

Wonder if Intel will go "well, we increased the cores by 50% so we also need to increase price", or if they will finally bring the price back down to $320 for the top model due to competition. Tired of this $420 nonesense.
