[hpsdr] NVIDIA Jetson Nano SBC - YouTube video

[Shirley Márquez Dúlcey]

Cost. The Odroid is $79 with 4GB RAM (the only version currently
available) and the NVidia is $99 if you can get one at list price.
(Supply is currently limited and resellers that actually have stock
are marking them up. You can get them at list price directly from
NVidia but their shipping charges are higher than some other sources.)
A Mini ITX motherboard plus an i7 CPU will cost much more. Even
combining that motherboard with a cheap Intel processor like a Pentium
will cost quite a bit more.

Some ballpark numbers (price reference: Newegg):
Motherboard: $80 (Mini ITX isn't a bargain, Micro ATX can be had for around $55)
Current i7 processor (i7-8700): $300
Current Pentium processor (G4400, about to be discontinued): $65
Alternate more recent Pentium processor (G5400): $75
4GB DDR4 RAM (one DIMM): $20

So even with the cheap processor it's $165, and the case and power
supply are also going to be more costly than the ones for the single
board computers.

The Jetson Nano looks really promising for DSP applications. Although
its four Cortex A57 cores at 1.43 GHz are nothing special (the
Odroid's four A73 cores at 1.8 GHz has that easily beat), the 128 CUDA
compute units on the GPU offer massive floating point math capability.
