Intel's Core i7 & i5 Kaby Lake X  Specs & Prices

Moving further down the food chain we have Intel's small, two SKU,  Kaby Lake X family. It includes a quadcore hyperthreaded i7 part dubbed the 7740K and a quadcore i5 part that lacks hyperthreading dubbed the 7640K.

The Core i7 7740K represents a sidegrade to Intel's Core i7 7700K in terms of specs, but the company hopes that its presence on the more feature-packed X299 platform will attract more enthusiasts to it.  It runs at base clock speed of 4.3GHz, a meager 100MHz higher than the 7700K,  and a boost clock speed of 4.5GHz matching that of the 7700K. It also has the exact same amount of L3 cache, which is 8MB. Although sadly it is rated at a noticeably higher TDP of 112W. It's also priced the same as the i7 7700K at $339.
