Intel Skylake-X and Kaby Lake-X CPUs to launch on Intel's LGA 2066 socket

Intel's i5 7640K and 7740K are likely to be part of their Kaby Lake-X lineup

 
A few days ago the rumours started flying around that Intel was creating new Kaby Lake CPUs to combat AMD's upcoming Ryzen processor lineup. Now it seems that these rumours are indeed true, but not in the way that many expected. 
 
These rumours prompted some additional research into older Intel CPU leaks, with previously leaked roadmaps suggesting that Intel would be releasing 112W Kaby Lake-X series CPUs on their upcoming LGA2066 socket alongside their new Skylake-X lineup. These CPUs were rumoured to be quad cores like their Z270 equivalents, 
 
Intel's Kaby Lake-X CPUs were rumoured to be quad cores like their Z270 equivalents, with featuring higher TDPs and clock speeds than their recently released Kaby Lake-S counterparts. 
 
Recently, Canard PC released specification of Intel's upcoming i5 7640K and i7 7740K, showcasing some improvements in stock CPU clock speeds and the addition of Hyperthreading to the i5 model. It is likely that the addition of Hyperthreading means that Intel are planning to remove other features from the CPU like AVX decode support, just like Intel has recently done with their hyperthreaded Kaby Lake CPUs.

Intel Skylake-X and Kaby Lake-X CPUs to launch on Intel's LGA 2066 socket

 
Intel's Kaby Lake-X CPUs will offer similar features to their Kaby Lake-S counterparts, though the CPU's integrated graphics processor will be disabled.   

With a TDP of 112W Kaby lake-X CPUs will have higher clock speeds than their desktop LGA 1150 counterparts and may potentially have more overclocking headroom. This CPU will likely be the entry level CPU for the LGA 2066 platform, giving its users the opportunity to upgrade to a CPU with more cores and PCIe lanes at a later date. 

The Kaby Lake-X CPU is said to only support dual channel memory, whereas the Skylake-X CPUs will support Quad-channel memory, making Kaby Lake-X CPUs limit the potential of future X109/LGA 2066 motherboards.

Some early reports have stated that Ryzen has very similar IPC to Intel's modern CPU architectures, which means that Intel CPUs may not offer the best per-core CPU performance moving forward. This gives AMD a huge opportunity to regain some market share from their rival and presents Intel with their first true challenge years. Ever since Sandy Bridge Intel only needed to compete with themselves and their previous generation products, but now it look like the CPU market will be returning to true competitiveness.
