So the power requirements have gone up by 34-50% in a single generation. Doesn't come as a surprise though.
At the same time, this power increase was to be expected considering the design of the chip itself and the performance it has on offer. The chip delivers an 8x performance boost in AI workloads while being 5 times more efficient.
A recent Gigabyte Server roadmap also showcased how CPUs, GPUs & APUs are getting close to the 1KW power barrier. AMD certainly has the most power-hungry chip of all but the red team has also invested in a host of chiplet and packing technologies that allow them to significantly reduce power requirements.
Having chips stacked and packaged together also helps to reduce the relative
Bits/Joule cost. So far, advanced packaging has alone provided a 50x reduction in communication power compared to when these chips were all stand-alone and put far to each other across the board.
Though efficiency is not a linear progression-like performance. Based on CPU & GPU efficiency trends, we are starting to see the progress flattening out so while achieving "Zettascale" performance in the next 10 years or so will be achievable, it will come at a
significant efficiency cost.
