The x86-64 chip in question is AMD's Jaguar design which was meant to be used in tablets. The only reason the consoles had more power than you'd get in a tablet at launch is because they had 8 cores at high clock speeds while an actual tablet using Jaguar would presumably only have 2. It's been a few years and the ARM64 designs are pretty impressive so if this is a quad core part or better it should be competitive.
