It is important to note that the GCN/radeonsi Radeons are very different to the earlier parts. For the 7850/Pitcairn parts there is kernel modesetting support but no 2D or 3D acceleration because all acceleration depends on glamor-egl and LLVM. If you're after acceleration for now it is <= Haswell for Intel (excluding Bay Trail) or <= Northern Islands for Radeon.
