AMD Radeon Pro 490 to be faster than GeForce GTX 1070?

We're still not quite sure what to make of all these rumors, there are whispers that a Radeon RX 490 card will be released very soon but part of me feels there are way to little details to make this genuine. Either way, WCCF Tech claims the card is a go but is still not sure whether it's based on Polaris or the new Vega architecture. If it's real it's probably going to be a dual-GPU Polaris. Maybe we'll learn more at AMD's December 13 press event.

AMD Radeon RX 490 Expected Details:

The card will target the 4K resolution and be the go-to graphics card for VR.

Top cards will have a bus width greater than 256 bits.

It will be based on either a dual-GPU Polaris 10 design (rumor) or Vega 10.

Its going to be close to the price point of the Nvidia Geforce GTX 1080.

Then there's also a rumor that AMD is working on a Radeon Pro 490, which is believed to end up in the next-generation Apple Mac Pro. It's a bit weird to have two products with such a similar name, but there seems to be clarity here that the Radeon Pro 490 will be based on the Vega architecture.

There are also some leaked Radeon Pro 490 performance figures, which are probably not too credible. The source claims the Pro 490 will be clocked lower than the RX consumer parts, so a best-case scenario is probably something close to GTX 1080 performance. So not that great really considering the rumored launch date is almost a year after the launch of the GTX 1080. Then again, I have my doubts about this leak.
