”That being said, I only had a couple other performance problems on the Core i9 7900X. In AIDA64, the FPU Mandel test would not bump up all the cores into action while running at stock speeds. The only way to get a true result in the test was to manually bump the CPU cores up to the Turbo Boost speed in the BIOS. In one of the game tests, the Skylake X i9 7900X delivered a lower level of FPS when compared to the Broadwell-E and Haswell-E processors. Throw in the other few odd results and we can chalk it up to an immature processor. Overall, the Core i9 7900X delivers significant performance margins over just about anything on the market right now. Now, when I looked at the overall performance of the Kaby Lake X Core i7 7740X, I got just what I expected, with some performance outliers that did not resolve out with even more benchmark cycles. I saw some results that should have seen it outperform the socket 1151 Core i7 7700K during both the stock and overclocked testing, but it still fell a little bit short. Overall, with the larger socket and dual channel DDR4 2666MHz support, it can get the job done”
