Intel Pentium vs. AMD Ryzen 3 Performance For Linux Gaming
With the rather CPU limited BioShock Infinite Linux port, the fastest combination was the Pentium G4600 with the Radeon RX 560 while on the Ryzen 3 1200 side there was better performance using the GTX 1050.
Under Counter-Strike: Global Offensive the game at 1080p was limited on the Pentium G4600 by the CPU with about the same performance between the RX 560 and GTX 1050 while under the Ryzen 3 1200 setup the GTX 1050 2GB ended up being much faster than the RX 560 4GB graphics card.
Deus Ex: Mankind Divided even with low quality settings at 1080p wouldn't really be playable with this class hardware, but for what it's worth, the Radeon RX 560 was delivering the fastest results and about the same performance between CPUs.
Dawn of War III with Vulkan has a tough time at 1080p and between the tested Radeon and NVIDIA GPUs saw about the same performance on the G4600 CPU while under the Ryzen 3 1200 there was much better performance with the NVIDIA GTX 1050.
