According to our friends at HardwareBattle, who as you know are quite accurate when it comes to AMD leaks, The Red Team is planning a major offensive in June.
AMD Radeon R9 490(X) are based on Polaris
AMD’s Radeon 400 series will launch in June. The preview may happen at Computex which starts end of May. However the official launch will take place end of June. So we are probably looking at paper launch at Computex and hard launch with reviews later that month.
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.
What you should know however is that Radeon 490 series will be direct counterparts to GeForce GTX 1080/1070 line, so it may give us some idea on Polaris 10 performance. It’s hard to say if Pascal GP104-based products will be faster than GM200-based cards, but judging from the past they should be. So technically Polaris 10 should also be faster than GTX 980 Ti, but that’s just pure speculation at this point.
Of course we will do our best to confirm this information, but for now treat it as a rumour.
