As for stacked Ram. A 14nm PS4 Apu is small and cool. |
This is an error most people make. Actually, the situation is exactly opposite of what you think. A 14nm APU might dissipate only 60% of the heat of a 28nm APU (assuming leakage problems can be solved which greatly increase as the process scale decreases) . However the heat density is now much higher, because the die size of the 14nm APU is considerably smaller than the 28nm APU. Cooling becomes more critical the smaller the die surface is, because you have "less surface area to dissipate heat".
