Not too long ago a slide could be found around the Internet supposedly identifying the specs for all of Intel's Core X-Series CPUs. It looks like that slide was correct as Intel has now shared it with a press release about the upcoming launch its remaining HEDT processors, including the $1999, 18-core/36-thread i9-7980XE.
That top-end part has a base clock of 2.6 GHz with a boost clock of 4.4 GHz (via Turbo Boost Max 3.0). It also has 44 PCIe lanes off of the chip. In fact, all of the X-Series CPUs above and including the i9-7900X have 44 PCIe lanes, which are all $999+ chips. The Intel X299 chipset can add up to 24 PCIe lanes on top of that, for a total of 68. AMD's soon-to-release Threadripper HEDT CPUs though all have 64 PCIe lanes off of the CPU, and its top-of-the-line 16-core/32-thread Threadripper 1950X only costs $999.
The 12-core/24-thread i9-7920X will be available on August 28 for $1199 while the 14- to 18- core CPUs will be available starting September 25 for $1399 to the aforementioned $1999. The i9-7920X has a base clock of 2.9 GHz; the i9-7940X (14-core/28-thread) has a base clock of 3.1 GHz; and the i9-7960X (16-core/32-thread) has a base clock of 2.8 GHZ. All of these CPUs have a Turbo Boost 3.0 boost clock of 4.4 GHz, with the Turbo Boost 2.0 boost clocks are 4.2 GHz or 4.3 GHz.
