A couple days ago we reported on the guys over at overclocking.guide having successfully unlocked the RX 460 to the full 16 Compute Units giving RX 460 owners essentially free performance. Early in the leak cycle of the Polaris cards it was believed that the RX 460 would launch with 16 CUs resulting in 1024 Stream Processors, but when it came to the actual launch of the RX 460 we saw the cards come out with only 14 CUs and 896 Stream Processors. This left much speculation around the Polaris 11 based cards not being fully enabled and the possibility of may something along the lines of an RX 465 down the road.
