i5 9400F: + can boost clock of an individual core very high + offers good performance without overclocking - no hyperthreading - upgrade probably requires new RAM and mainboard Ryzen 5 2600: + compatible with next gen of AMD CPUs (upgradable) + good workstation performance o after market cooler, overclocking and 3200 Mhz DDR4 makes it competitive - sup par single-core game performance So basically as long as a game used one thread at 100% and some more CPU cores at low utilization, the Intel will be perfect. On the other hand, if the game uses more than 6 threads with a high utilization the AMD will catch up and overtake. As some pointed out, simulating one large ship may favor high single-core performance, while simulating lots of small ships may favor high-thread-count CPUs. Has any of the players or devs done testing with both options? Is there any definite answer? Maybe I should formulate it differently: When the FPS drop, and the CPU is the bottleneck, how many CPU cores are actually highly loaded?
