The Pantera Pico PC has an x86/x64 based Intel processor, while the Raspberry Pi has an ARM-based chip. Although ARM-based chips are aimed towards mobile devices like smartphones and tablets, it has made its way to tiny desktop computers as well. Yet, one of the the biggest advantages an Intel based computer has, for the average user, is software compatibility: Most desktop applications (apps) are designed for/towards x86/x64 chips. Meaning, there will be many for-desktop software that will not work on the Raspberry Pi.
Depending on your use case, there may be some of your regular Windows software that may have a workaround on the Pi, though definitely not as readily and easily on an x86/x64 Intel-based chip like on the Pantera Pico PC.
