Intel Readies the Core i9 Brand Extension
Intel is reportedly giving final touches to a new line of high-end desktop processors under the Core i9 brand extension. Until now, the company used the Core i7 brand extension broadly, to cover both the top-end parts of the mainstream-desktop (LGA115x) segment, and the high-end desktop (HEDT) segment, consisting of the LGA1366 and LGA2011-series sockets. With the advent of the new LGA2066 socket, Intel will be launching two distinct kinds of products - the Core i7 "Kaby Lake-X" quad-core series; and the Core i9 "Skylake-X" 6-core, 8-core, 10-core, and 12-core processors.
The Core i7 "Kaby Lake-X" will include the much talked about Core i7-7740K and i7-7640K quad-core processors (there's no Core i5 Kaby Lake-X). These chips will feature up to 1 MB of dedicated L2 cache per core, which is four times that of the existing i7-7700K chip. The i7-7740K features 8 MB of shared L2 cache; while the i7-7640K features just 6 MB. Interestingly, the i7-7640K also happens to lack HyperThreading, while the i7-7740K features it. The i7-7740K will ship with higher clock speeds than the i7-7700K, with 4.30 GHz core, and 4.50 GHz Turbo Boost. The i7-7640K features 4.00 GHz core, with 4.20 GHz Turbo Boost. The Core i9 series is a whole different beast.
The Core i9 series will consist of four parts, the Core i9-7800X six-core, Core i9-7820X eight-core, Core i9-7900X ten-core, and the Core i9-7920X twelve-core. All chips feature HyperThreading, and 1 MB of dedicated L2 cache per core. The i9-7800X features 8,448 KB (8.25 MB) of shared L3 cache, and comes with clock speeds of 3.50 GHz core, and 4.00 GHz Turbo Boost. The i9-7820X eight-core chip features 11,264 KB (11 MB) of shared L3 cache, clock speeds of 3.60 GHz core and 4.30 GHz Turbo Boost. The Core i9-7900X ten-core chip features 14,080 KB (13.75 MB) of shared L3 cache, and clock speeds of 3.30 GHz, with 4.30 GHz Turbo Boost. Clock speeds of the top-dog i9-7920X twelve-core chip are unknown at the moment, but it comes with 16,896 KB (16.5 MB) shared L3 cache.
The i9-7800X, and the i9-7820X, along with the "Kaby Lake-X" based quad-core parts, feature 28-lane PCI-Express gen 3.0 root complexes, so your 2-card SLI/CrossFire setup will run at just x8 per card. The i9-7900X and i9-7920X feature 44-lane PCIe gen 3.0 root complexes, which enable the 3-way/4-way multi-GPU setups you originally bought any HEDT chip for. Further, the "Kaby Lake-X" quad-core parts feature just dual-channel DDR4 memory interfaces. The entire Core i9 "Skylake-X" series features quad-channel DDR4 memory interface. Socket LGA2066 motherboards will feature quad-channel wiring, with up to 8 DIMM slots, but when a Kaby Lake-X chip is installed, two memory channels are inactive.
Intel is expected to launch most of the Core i7 "Kaby Lake-X" and Core i9 "Skylake-X" lineup in June 2017, with the top-end i9-7920X following on in August, 2017.

What does TPU do all weekend? :ohwell:
Drink Beer? :toast: :roll:
This sounds like a big fail , bar the top two the others are no more appealing then an i7 77ook in many respects yet will have a big markup, i can't see them doing well unless they rejig their entire price list for consumers, that's not going to happen.
I accept the upgrade later route via a shit early chip but how many actually do that, in all honesty most enthusiasts swap whole platforms each time as do average joes so i can't see the point in so many shit( in the context of the motherboards available features not being used) low end chips for a very pricey platform.
None of the multi-CCX chips actually keep up with the i5k or i7k chips... I would wager this problem will persist with the R9 chips will have the same problems.
The i7x and Xeon chips have shown no such weakness aside from the clock scaling when going through the 4-16 core range, maybe the very large chips might have noticeable latency problems in gaming performance, but none of the chips a gamer would buy do. On the other hand, the CCX issue affects the entire AMD gaming lineup outside of the budget sector, and if the IMC problems aren't fixed soon, they are going to be in deep doo-doo.
Due Intel AVX-512 enable now we've got some miracle choice.
+Intel AVX-512 can be 2X AVX/AVX2/AES speed compare to Ryzen 3,5,7,threadripper,naples and all Intel older processors on markets.
+Each core increase L2 cache from 256KB to 1024KB that 4 times from skylake/kabelake 1151 and all predecessor.
+Each core has 1.375MB L3
+Intel Turbo Boost 3.0
Consider Core i9 7920X 3.5GHz 12 Core 24 Thread 16.5MB L3 160watt TDP
12 x 64KB L1 cache 12 x 1024KB L2 12 x 1375KB L3 with AVX-512 support may overkill 16/32 Ryzen part easily.
