This is the chip AMD will be using in the notebook segment, Polaris 11, and its performance is, as expected, around 50% of the RX 470, because it has, well, 50% of the grunt. The problem, though, is price. With an MSRP of $110 (no reference editions so there will be variations between board partners, like the RX 470), and some RX 470s at $190, that's a 58% price difference for a 100% increase in performance. Even more troubling is the existence of the older and FAR more capable R9 380X, like the PowerColor PCS+ Radeon R9 380X DirectX 12 AXR9 380X 4GBD5-PPDHV2E 4GB 256-Bit GDDR5 PCI Express 3.0 CrossFireX Support A… , which packs over 3x the performance of the RX 460 while carrying a $150 price tag (or $170 without rebate), making it both faster and less expensive than even the RX 470.
Anyway, the RX 460 looks good, but until that price tag is around $90, or half of the RX 470's price, I can't recommend it, not when you'll have to make details compromises in even World Of Warcraft. Granted you could say that this card wasn't meant for 1920x1080, but this is 2016, 1920x1080 displays, and televisions, are dirt cheap, there should be no lower resolution targeted. In laptops this chip will do nicely because 1920x1080 is still sadly on the rarer side, but as a desktop variant it doesn't make any sense to have 1600x900 or 1680x1050 as your target resolution.
