So... did AMD announced what was their new goal regarding MANTLE? they promised to state it today... unless it was just vapor like 98% of their stuff lately.
My opinion: once the original plan failed, AMD will maintain now Mantle as a kind of internal API for experiments and so, will do a pair of public announcements and occasional demos just to say the API is alive and well, and then will leave it die silently until finally no one remember it.
The title and main text are a bit incorrect. The author posted an update explaining that "
the 20 percent improvement was in addition to the frame-rate increases that Microsoft has disclosed previously". I.e. it is a 20%
extra improvement on top of the >50% improvement from DX11-->DX12. The total improvement was >80% over DX11.
As stated before DX12 will be faster than Mantle and will introduce new stuff is not in Mantle. In this case the extra 20% is from using the "
new ExecuteIndirect feature". Note as well that the demo used an Intel Core i7 4770R (with Iris Pro graphics 5200 installed), which invalidate certain ruminations made before about Intel graphics in this same thread.
