a RX 465 with a reasonable price is what AMD needs to compete again in the low-midrange sub $150 , sub 75W TDP mark. The RX 460 struggles even against the older GTX 950.
It would also showcase the new driver improvements (about +3% I believe) since reviews don't tend to go update after a major driver release.
It's not going to happen. AMD is just too far behind Performance to TDP wise. This market is dominated by the need to be able to run both quietly and with only the 75W of power a PCIE connector provides. What AMD needs more is to differentiate their gpu's and give better value-added services versus Nvidia. Their recent patch was a good step forward in that aspect.
