Intel Core i9 9900K vs. AMD Ryzen 7 2700X Linux Gaming Benchmarks
BioShock Infinite is one of the older Linux game ports and rendering with OpenGL. At 1440p with very high quality settings it's still a rather CPU bound game on modern hardware. In this instance the Core i9 9900K was 48% faster than the Ryzen 7 270)X for the average frame-rate. The peak frame-rate was 50% higher with the Intel CPU for this game.
During this game, the average CPU power consumption was 213 Watts for the Ryzen 7 2700X and 221 Watts for the Core i9 9900K. In the end though the 9900K had a performance-per-Watt paired with the RX Vega 64 that was 42% more efficient.
When running Dota 2 with OpenGL the average FPS was similar between these processors at 4K.
In this case the Ryzen 7 2700X had slightly better power efficiency.
But when switching over to Dota 2's Vulkan renderer, there was a slight lead on the Intel side.
