AMD Radeon R9 490X to launch in June, Radeon Pro Duo on April 26?

Two new AMD video card rumors hit the web. First up VideoCardz came across a rumor that April 26th will be the availability date of AMD's long-delayed Radeon Pro Duo dual-GPU video card. Reviews may hit the web a bit sooner but given the $1,499 price tag there will likely be little consumer interest in this card.

Next the site writes that AMD is planning to launch its Radeon 400 series towards the end of June, with perhaps an early preview at Computex in late May.

If the source is correct, the Radeon R9 490(X) will be based on Polaris 10 but there's still a lot of uncertainty about the performance level of these cards.

What’s more, Radeon R9 490X will be based on Polaris 10. It means there won’t be any Fiji to R9 490 rebranding. This leaves us with two possible scenarios. Either Fury X is faster than Radeon R9 490(X) Polaris 10, and Fury series will be offered alongside Radeon R9 490 line till Vega 10 becomes available, or Fury X is slower than Polaris 10 and it may be used for Radeon R9 480 series instead.
