Could the Rock Pi 4 aims unseat the Raspberry Pi 3 Model B+ as the top contender in the cheap computer world? This ebook offers a hands-on review, along with performance benchmarks and specs so you can see if it’s the right board for you.

From the ebook:

The days of sub-$100 computers being too slow to do anything useful are long gone.

Arguably it was launch of the Raspberry Pi in 2012 that proved to the wider world that cheap computers could be capable machines.

Since the release of the $35 board, an army of imitators have borrowed its name, with the hope of capitalizing on the world’s insatiable appetite for the Raspberry Pi, today one of the world’s best-selling computers.

One of the latest rivals to jump on the Pi bandwagon is the Rock Pi 4, a board whose specs roundly trounce the Raspberry Pi. But does that technical superiority make the Rock Pi a better computer? That very much depends on what you want to do with the board and your expertise using Linux and single-board computers.
The performance of the Rock Pi 4 certainly outstrips that of the flagship Raspberry Pi 3 Model B+ (as you can see in the benchmarks below), but it also lags behind the Raspberry Pi in several important respects.
