Rocket League (Testing):
Oldest PS4s = 130watts while playing (63 dB)
PS4 Slim = 63watts while playing (43 dB)
^ that is crazy.
Not only that it runs like 5-10 degree's cooler as well, while makeing that much less noise.
Thats under half the power usage of the oldest PS4 models.
Also each dB is a doubleing in noise levels, those 20+ dB differnces are HUGE.
(eurogamer did a Xbox One S review, and they had the it at 44-45 dB, this is less noisy)
