So I have a HTPC that I use for light gaming, with the performance target of 1080@60. I recently had a 2200G in there, which was fine, and I got decent FPS at FarCry 5 (below). I chose this game to be the defacto benchmark because of how CPU sensitive it is. I bought a 2600 (non-X), and installed it, and my FPS sucks! Min, Avg, and Max are down significantly. Thinking its a compatibility issue, I upgrade my chipset drivers, bios, graphics drivers, install Ryzen Master, etc.. Still the fps sucks. And yes, I made sure vsync wasn't on, game settings were the same, radeon settings same, etc..
In Open Hardware Monitor, I see the 6 cores with Max freq values of 3900mhz, so I know they are hitting their listed top speed. CPU Utilization is 100%, and GPU utilization is close to 100% too. All clocks and temps appear to be fine. In Cinebench R15, R20, and wPrime 1024, my 2600 gets similar scores to other 2600, although a few % points lower.
How is my lowly 2200G, and especially my ancient I3, crushing my 2600?
