Intel Core i7 7740X Preliminary Benchmarks On Linux

Right off the bat we see for some workloads, the Core i7 7740X is barely any faster than the Core i7 7700K. The i7-7740X benefits from a 100MHz higher base clock frequency than the i7-7700K while they both have the same 4.5GHz turbo frequency capability. The i7-7740X also natively supports DDR4-2666 rather than DDR4-2400/2133 of the Kabylake non-X processors.

In non heavily threaded workloads, the Core i7 7740X comes out as the fastest CPU tested, with the Ryzen 7 1800X not having as good single-threaded performance.
