AMD Ryzen 5 2600 / Ryzen 7 2700 Benchmarks On Linux, 9-Way Ubuntu CPU Comparison
While in the Stockfish chess benchmark, Intel Coffeelake CPUs were much faster, with even the i5-8400 beating out the Ryzen 7 2700X in this C++11 chess benchmark.
OpenSSL was another test case where Intel's current micro-architecture is still doing better than Zen+ with the i5-8400 running just behind the Core i5 8400, even with this OpenSSL benchmark configuration being multi-threaded.
With the POV-Ray multi-threaded ray-tracer, the Ryzen 7 2700 was beating out the Core i7 8700K by a few seconds while the Ryzen 5 2600 was just seven seconds slower than the 2600X.
The Ryzen 5 2600 and Ryzen 7 2700 understandably do better than the X models when it comes to their performance-per-Watt and thermal performance.
