Intel’s new Skylake-X CPUs appear to perform worse than the existing Kaby Lake family of processors. To be more specific, the Core i7-7800X fails to provide better performance than the Core i7-7700K in benchmarks done by folks from TechSpot.
Before we dive into the gaming benchmarks, it’s worth noting that the Skylake-X Core i7-7800X CPU features higher core counts, higher L3 cache, and significantly higher L2 cache compared to the Core i7-7700K. Despite this, the former processor does come with lower clock speeds out of the box.
Some of the games that were tested are World of Tanks, Grand Theft Auto V, PlayerUnknown’s Battlegrounds, and The Witcher 3: Wild Hunt. Based on TechSpot’s findings, it can clearly be seen that the Core i7-7700K is performing better in gaming compared to the Core i7-7800X. Overclocking also tells a similar story. Do keep in mind that both CPUs are paired together with a GTX 1080 Ti graphics card.
According to Overclock3D, the reduction in gaming performance of the Intel Skylake-X processor may be down to the new “mesh” bus architecture that Intel has implemented with this CPU. Kaby Lake CPUs feature Intel’s “ring” bus architecture. That said, one has to remember that the Skylake-X processor may perform significantly better in applications that are well optimised for higher core counts.
Regardless, if you’re a gamer who is eyeing on getting a swanky new Core i7-7800X CPU, you may want to reevaluate your options.
