Intel Core i9 7900X Linux Benchmarks
With the Parboil workload over OpenMP, the Core i9 7900X comes out in first place, to not much surprise, followed by the AMD Ryzen 7 1800X and Ryzen 7 1700. In fourth was the Xeon E5-2687W v3, a similar ten core + HT CPU but based on Haswell and just a 3.1GHz base frequency and 3.5GHz turbo.
The i9-7900X with Rodinia did very well and is where Ryzen pulled back with falling behind the Xeon E5-2687W v3 and with the OpenMP Streamcluster to the i7-5775C and i7-6800K.
With Numpy, which isn't multi-threaded, the i9-7900X came in behind the i7-7700K and i7-7740X but at least still well ahead of the Ryzen CPUs.
