Earlier this week, Oculus opened pre-orders for systems and configurations that it believes will deliver an acceptable VR experience. Overall, it’s probably best if consumers hold off on pre-ordering VR equipment — but since we’ve spent most of our time discussing the GPU side of the equation, the CPU deserves some love as well.
Jason Evangelho of Forbes sat down with AMD to talk about its processor support for VR and whether the company’s FX and APU families can drive headsets like the Oculus Rift. The good news is, they absolutely can, even if the current version of the Oculus hardware tester claims otherwise.



Originally, AMD told Forbes that there were a variety of AMD FX processors that could handle VR, as well as some of the highest-clocked APU processors. The company has since walked back its APU claims, however, and is now saying that only the FX chips have been validated. If you have an eight-core or six-core AMD CPU with a base clock no lower than 3.9GHz, you should be good to go with VR.
The fact that AMD is still validating VR on its APUs doesn’t mean those chips can’t handle the technology, but it may be difficult for them to do so. Even AMD’s upcoming A10-7890K, with a supposed 4.1GHz base clock and 4.3GHz boost clock isn’t all that powerful compared to Intel’s Core family. Since AMD CPUs can’t match the single-threaded performance of Intel chips, which is why AMD positions its multi-core offerings against Intel processors with a lower core count. According to Oculus’ recommendations, the minimum Intel chip you should use is a Core i5-4590. That’s a 3.3GHz quad-core with a 3.7GHz Turbo clock, 6MB of L2 cache, and no Hyper-Threading.
