para ser de gama extrema le faltan núcleos y solo soporta 64 gigas de ram,alto precio para lo que es


Excellent

Es el mejor procesador de cuatro núcleos que se haya fabricado hasta la fecha 2018/01/27


Good

3 years ago.

Probably one of the worst possible solutions for anyone building a PC. It's rather expensive, offers practically no performance over the i7 7700K while equally priced Ryzen 7 1700 beats it almost everywhere, including in some games.


Poor

18 months ago.

Kaby Lake-X CPUs is probably one of the Intel's most embarrassing release ever for their HEDT platform. Requires X299 motherboard and only offered 16 PCIe lanes whilst being only little better than i7-7700K.
