ARM64 plus single 3d 2d and audio codec GPU acceleration.
When you are not doing much it can load files more from a cache on one of the SD cards 4*256gb.
The space usage does not take up the full space 920gb for throughput efficiency and longitevity. It also operates on the 2 lower cores and a lower GPU range use the lower 2 GBs much as possible plus a secondary single SD 1 GB swap.
In the fast lane all six upper cores are in gear the 2 GB eco ram is cached and their is a fixed 3 GB swap cached so with some compression and some caching management it will work roughly the equivalent to a 16gb system and the CPU does compression quite well for efficient arm working.
The arm chip being energy efficient and small could do up to 4GHz and use the case to cool. It could focus the the heat effort more to the effort of codec acceleration processors without heating on more unecceserary processes and places and the 10 GB ram should have eco standard and turbo mode.
Upto 12 tflops low precision calculations and 1.2 tflops 32 bit.
Basically like the new Nintendo with better upscaling at the cost of more watts. Unreal engine 5 can be adapted to such a platform with the right range of compression and reductions.
That's what a reasonable 5nm ARM mini PC could achieve at 1.2 and with gate all around you could be taking upto 4.8 GHz cooler and 8Tflops 32 bit and 94 tflop low calc.
With optical acceleration a few more years later you could be talking 0.5 + peta flops low calc. At that rate you can do a lot more touching up beyond standard upscaling.
Go five years after this and full optical processing could be more mainstream and 700 tflop 32 bit and 12 peta flop low calc pin chips could be in systems. Games will be so powerful even on mini systems size will be less important.
