Tech Report looks into Mantle, even deeper. Yes, hardy har har.
In Mantle's case, according to Riguer, AMD has lowered the abstraction level in some areas but "not across the board." DICE's Johan Andersson described the traditional approach as "middle-ground abstraction," where a compromise is struck between performance and usability. Mantle, by comparison, offers "thin low-level abstraction" that exposes how the underlying hardware works. Riguer boiled it down further by comparing Mantle to driving a car with a manual transmission—more responsibility, but also more fun.
