No those blocks are not licensed by Arm (in those SoCs, they do offer the IP recently), every vendor mostly has their own designs. Again they have nothing to do with Mali nor any GPU for that matter.

Again you're using the argument of a non-power optimised development board, using higher frequencies than used in mobile, in open-air or cooler if you chose to, using broken drivers in a use-case where the true power would be 1/50th.

Like what exactly is your point here? Again we can go break any "15W" Intel chip and make it use 35W. Does it mean anything? No, it's just random numbers thrown around.
