NeoGAF verfied user: NX CPU is noticeably better then PS4 and Xbox One CPU

[silvergunner]

The Playstation 4 has a performance boost over the Xbox One as it uses GDDR5 RAM, which is a lot faster than the DDR3 RAM in the Xbox One. Because modern games require shifting through a lot of assets stored in RAM, a performance boost there is a major advantage.

Although the Xbox One is clocked slightly higher, both systems dynamically clock themselves upwards when required (just like modern PCs).
