> The processor seems to score less than an RPi4 on Geekbench.
The apu2 is an embedded AMD quad core 1GHz SoC consuming 5W. It is not a powerful system by any means and not surprised rivaled by a >1GHz quad core Arm.
The AMD Jaguar cores came out in 2013. On the other hand, the Cortex A53 came out in 2012 so it's still a bit embarrassing for AMD. That was before the AMD renaissance, though.
The Raspberry Pi 4 uses a quad core cluster of Cortex A72 cores, not A53. A72 was released in 2016, but the Pi 4 also has them clocked to run at 1.5GHz. Either way, I don't think it's embarrassing for AMD's 2013 Jaguar to be beaten by cores that are 3 years newer and running at a 50% higher clock speed. I thought Jaguar was pretty cool at the time that it came out, but technology has continued to move swiftly since then.
