One of the biggest concerns about Polaris 10 has been whether or not it will be a true replacement for Fury X. With the latest leaks out, most of the information points to about 100W TDP with 2304 shaders and clock speeds around 1050Mhz. Compared to Nvidia’s Pascal GP104, this doesn’t sound very competitive, leading to concerns that Nvidia would dominate the high-end. With the release today of AMD’s more detailed roadmap, our concerns have been laid to rest.
The new official roadmap offers a bit more detail than the one AMD showed back at Capsaicin. The new one offers more detail around Polaris 10 and 11, with both chips working to replace the entire Fury and 300 series lineup. This means the top Polaris 11 chip will offer enough performance to at least match, if not exceed Fury X. This should be competitive enough against GP104. If the 2304 shader report is true, AMD has truly revamped GCN 4.0 into something that is significantly superior to GCN 1.0 while cutting power consumption at the same time.
The layout for Polaris compared to the current lineup also suggests there will be no rebrands for the 400 series. It suggests that Polaris 10 will go from about 490X to 480 while Polaris 11 will fill in 470X down to at least 460. With how well small die low power Polaris 11 has done, rebrands don’t really make any sense. Finally, Vega will drop in 2017 with HBM2 and not in late 2016 as some have hoped.
With the improvements AMD has done, I am really looking forward to what Polaris and GCN 4.0 will bring to the graphics landscape.
