Intel Core i7 7800X X-series - Pros & Cons

strong single and dual-core performance
superior out of the box clock speed makes
performance we can make safe and accurate speculations

lacks support for the maximum 44 PCIe lanes
no desktop CPU as fast as the Core i9-7900X
There has been no official price drop from AMD
Intel has not officially dropped the prices of the older processors
only the top CPU came direct from Intel
early adoption is rather unsafe on its own
Discrete voltage control
Skylake-X degrade game performance clock-for-clock compared
in particular is heavy on power draw
there is no real knock-out blow for the mainstream Core i7 chips
