Ben tears apart a PlayStation 4 Pro and compares it to a recently torn down PlayStation 4 Slim. He also compares it to an Xbox One S he recently tore apart as well and talks about its most glaring omission, the lack of 4K support for its blue ray drive. Like the Xbox One S it has a wireless module outside the main RF Cage but in this case they have 3 antennas on them. Unlike the Xbox One wireless isn’t a separate module it’s just an exposed module on the main board. The Pro4 is notable for its lack of 4K blue ray support and initially appears to be the same system as the original but with a bigger APU (accelerated processing unit). A large copper plane is used for the heat sink as opposed to the steel on the PS4 Slim. The top of the unit looks like its power supply, heat sink, and blue ray drive. There’s twice as much power regulation as the PS4 Slim. There’s a built in speaker beeper like the Xbox One. Ben gives his theory on why dies shrinks every time they do a new revision of a console. After getting the die of the PS4 Pro cleaned up he compares it with the Die of the PS4 Slim. There’s more surface area to pull heat from the chip. The biggest difference between the motherboards of the two systems is that they have a lot more power regulation going on and a larger die that sinks more heat in. The heat sink of the new system is about 30% bigger than the old one. It's longer and a little bit thicker. There’s three heat pipes coming out of a copper core and those heat pipes are going directly to the top of the fins of the heat sink. There’s quite a bit more heat dissipation going on with this unit. Ben compares the power supply of the PS4 Pro with the one on the Slim. There’s a pretty big jump in power consumption on the new system. The 12 Volt rail on the new power supply is 23.5 amps. That is nearly twice as much as the Xbox One S. Finally, Ben compares the Blue Ray Drive of both systems. In comparing both drivese, Ben ge
