These loads typically require special advanced materials, active cooling, or both for the structures to survive the environment.
The heat and particle exhaust must be handled in steady state with specialized tiles and active cooling.
That is because such a complex process may require temperature stabilizers and active cooling, which can't be mounted into a small sized host.
Originally, video display controllers were fairly low power devices without any need for active cooling.
The ion laser tube produces a lot of waste heat and requires active cooling.
Therefore studies often plan on "active cooling", where coolant circulating throughout the vehicle skin prevents it from disintegrating.
There was no active cooling, and at least the 0511.2 variant tended to overheat and halt after several hours of operation.
However the period between July and August corresponds with the warmest months on the northern hemisphere so active cooling might be necessary.
Hence effective active or passive cooling for spent nuclear fuel is required for a number of years.
I have serious doubts the new chip could handle that, at least not without active cooling and much worse battery life.
