It appears there will be four new 14nm chips; the Core i7-6800K, the Core i7-6850K, the Core i7-6900K, and the Core i7-6950K. All four chips are compatible with existing LGA2011v3 motherboards (after BIOS update) and have an unlocked baseclock and a 140W thermal envelope. Availability is slated for Q2 2016.
The Core i7-6800K and i7-6850K are six-core chips, with HyperThreading enabling 12 logical CPUs, and 15 MB shared L3 cache. The i7-6800K is clocked at 3.40 GHz, with a 3.60 GHz Turbo Boost frequency. The i7-6850K is a notch above, with 3.60 GHz core, and 3.80 GHz Turbo Boost frequency. The slide doesn't mention if either of the two parts feature a limited PCIe root complex, like the one on the i7-5820K.
As we move up the lineup, there's the Core i7-6900K. This is an eight-core chip, with HyperThreading enabling 16 logical CPUs, and with 20 MB L3 cache at its disposal. Its core is clocked at 3.20 GHz, with a rather healthy 3.70 GHz Turbo Boost. At the very top of the lineup, is the Core i7-6950X. Intel's first consumer 10-core chip, with HyperThreading giving your OS a whopping 20 logical CPUs to deal with, this chip features 20 MB L3 cache, and is clocked at 3.00 GHz, with 3.50 GHz Turbo Boost.
