Quote:Going into this review, we suspected Kaby Lake-X wouldn't be anything too impressive, mostly because these quad-core CPUs have no place on a high-end desktop platform that they can't fully drive. The fact that they provide weaker performance and greater power consumption than the original Kaby Lake processors only adds insult to injury.
These performance issues could be blamed on the X299 board we used and motherboard manufacturers sure appear to be somewhat of a scapegoat for this sloppy release. That said, the Asrock X299 Taichi appeared flawless for me when testing the higher-end 7800X, 7820X and 7900X CPUs.
After recording such odd results I looked around to see what other reviewers found during their testing. Mixed results are the norm with Kaby Lake-X being slower for the most part across a range of hardware. However, the confusing power consumption figures I recorded haven't been seen by everyone.
...
Here we are five weeks later and I'm confident in suggesting that you shouldn't buy a Kaby Lake-X CPU. Glad to have that off my chest.
