How does that projected number, 40TFlop, correspond to the manufactoring process of 10 nm? I have forgotten the maths behind die shrinks (the correlation between process shrink to amount of transistors and power consumption). Could a shrink from 28nm (today) to 10 nm really allow an increase of around 20 x the processing power that we today get from a 100W GPU? |
Its roughly 8-9 times more transistors from 28nm to 10nm. So you could get a 8-9 times increase in raw gpu performance just by putting 8-9 28nm Gpus on the wafer, theoretically. But there is no math for that anymore the development isn't as straightforward as it once was.
It also depends on architecture. There are many transistors who have not really something to do with flop performance this comes from the cores. And I doubt Nvidia needs 9 times more of everything. So they probably target to put a higher percentage of transistors to use for flop performance than in current Gpus. Its possible to have a 20 times increase tflop performance from 28nm to 10nm it all depends on the architecture the wafer quality etc. Could be anywhere really without inside knowledge its impossible to say. Nvidia always reached roughly their goals. So a 30-40 Tflop 100-120 Watt Gpu from 2019-2022 can be expected.
