When comparing MinnowBoard Max vs The Parallella Board, the Slant community recommends The Parallella Board for most people. In the question“What are the best single-board computers?” The Parallella Board is ranked 18th while MinnowBoard Max is ranked 29th. The most important reason people chose The Parallella Board is:
The Parallella Board makes use of the Epiphany III coprocessor which is invisible to the OS unless directly addressed through its APIs. It currently boasts 32 gigaflops from its 16-core variant with a promise of 100 gigaflops for a 64-core model which will be available in the future.

Pros
Pro Completely open source
MinnowBoard is a non-profit backed by Intel. meaning it gets advice for its architecture by Intel. But all hardware and software parts, including all drivers are completely free and open source.
Pro USB 3.0 available
The MinnowBoard Max has 2 USB ports, one of which is a USB 3.0.
Pro Great for hacking away
Other than releasing all drivers as open source, Intel has also made the schematics of the board available to download. This way, hackers can give it a try and build anything they want without restrictions.
Pro Amazing performance because of the Epiphany coprocessor
The Parallella Board makes use of the Epiphany III coprocessor which is invisible to the OS unless directly addressed through its APIs. It currently boasts 32 gigaflops from its 16-core variant with a promise of 100 gigaflops for a 64-core model which will be available in the future.
Pro Low cost Xilinx Zynq FPGA development
Although not a beefy FPGA, the price is right
Pro Excellent many-core RISC architecture
High performance, energy-efficient floating point capable, general purpose RISC cores
Pro Great board for programmers to experiment on different platforms
The Parallella is a great board for programmers to experiment programmin on ARM, FPGA and the Epiphany architecture in one compact package.
Pro Completely open source
Parallella uses open source hardware. The drivers are released as open source as well. All the details about the board designs and schematics can be found on GitHub.
Pro Ships with open source development tools geared towards Epiphany development
Parallella ships with several open source tools geared towards developing for the Epiphany architecture. Some of these tools include a C compiler, Eclipse, OpenCL SDK/compiler and runtime libraries.
Cons
Con Multi-USB hub almost a necessity
Because it has only two USB ports, one of which to be used for charging, a multi-USB hub is needed to connect a keyboard and mouse which are the absolute minimal external devices to be able to use and configure the MinnowBoard.
Con No official OS images have the kernel with GPIO enabled
Although this is not the board's fault per-se, no official OS image has enabled support for GPIO. But if the kernel is compiled from source, it can be compiled with GPIO and PWM enabled.
Con Not great for media streaming
The Parallella board was built to give everyone access to a mini-supercomputer. It's strength lies in the Epiphany which makes it great for parallel computing and image processing, unfortunately it's not good with media (audio and video) streaming.
Con Requires dedicated software development
Since it uses a different architecture than most boards, out-of-the-box software is not compatible with it. Instead, there's a huge GitHub repository with official ports of popular software compatible with the Parallella Board.
