Performance-Per-Watt & How The Raspberry Pi 2 + Pi Zero Compare To Old NetBurst CPUs

After starting to run some Raspberry Pi Zero benchmarks this weekend, I'm back today with more benchmarks. In this article is also an interesting comparison showing the performance of the Raspberry Pi Zero and Raspberry Pi 2 against old "Northwood" Pentium 4 and Celeron processors from the Socket 478 NetBurst days. The many results in this article also include power consumption and performance-per-Watt metrics for this $5 ARM single board computer.
