Is AMD Radeon RX 490 based on Polaris GPU architecture, or will it be the first graphics card powered by Vega 10? This was the question raised after the latest detail of AMD's upcoming graphics card surfaced.

Is it Vega 10 or Something Completely Different?

Back in July, claimed there's another AMD graphics card scheduled for release before the year ends. But since the two FinFET GPUs earlier announced by AMD, Polaris 10 and 11, has already been released, the mysterious graphics card was believed to be the first from Vega, AMD's next GPU architecture.

Why was it believed to be a Vega graphics card? First, AMD already released 'the most powerful configuration of the Polaris 10 GPU,' "Radeon RX 480". Therefore, unless AMD comes up with bigger GDDR5X RAM and other Polaris features, "Radeon RX 480" remains to be the last Polaris 10 graphics card.

Then, leaks supporting Vega architecture showed up. The first connected it with HBM2 while the second was for its release date. revealed that "Radeon RX 490" is a Vega 10 graphics card to be released by Q4 of 2016. The same report reveals that "Radeon RX 490" will be powered by HBM2 technology. Later, during AMD's Investor Presentation, it was reported that AMD will come up with Vega by 1H of 2017.

Questions about "Radeon RX 490" Features

As mentioned earlier, there are only two kinds of Polaris graphics card, Polaris 10 and 11. No one mentioned about having Dual Polaris 10 until recently when Usman Pirzada of first reveal about it. Apparently, Radeon RX 490 will be released by December.

Now this opens up a few questions about the credibility of Radeon RX 490. First, it is really the first graphics card under Vega architecture, or will there be Dual Polaris 10? Second, if Vega indeed will have the first HBM2 technology and will be released next year, what is the memory of "Radeon RX 490"?
