The slide leak, from VideoCardz, shows a slightly more detailed, product orientated, GPU roadmap.

It shows that both the Radeon Fury Series and Radeon 300 Series will be replaced by Polaris 10 and Polaris 11 GPU based products later this year. There does not appear to be a Fury replacement in 2016 and it will not happen until the Vega/HMB2 arrives.

The Polaris 10 ‘Ellesmere’ and Polaris 11 ‘Baffin’ look to cover all of the Radeon 400 Series products. Polaris 10 will be for the likes of the R9 490X, 490 and 480 models. Cards such as the R7 470 and R9 470 models will likely feature the Polaris 11 GPU. The  slide confrims the GCN 4th gen, HEVC encode and decode, HDMI 2.0 and DP 1.3 connectivity.

It looks like AMD is doing something radical with the Radeon 400 Series and bringing in a pure Polaris lineup rather than just rebadging old tech and hoping that no-one will notice. Polaris has already scored a role in the Apple Mac Computers and the PS4K.  It is also expected to score refreshes of the Xbox One and new Nintendo console.

The roadmap does seem to show speedy progress, with Vega/HBM2 coming hot on the heels of Polaris and then the mysterious Navi with ‘Nexgen memory’ arriving in 2018.  The AMD Vega, first architecture with HBM2, will arrive next year so not 2016 as expected. This roadmap clearly says there is no Vega this year.
