The new, ultra-compact Vnopn K1 does without a fan and has no moving parts, which helps keep its form factor down. Vnopn has equipped the K1 with an AMD processor too unlike many other PCs of its size.

Frankly, a 6 (!) year old CPU with outdated performance (half that of an Intel J4105 despite similar power requirements) is hardly worth mentioning. And to top it all off, this isn't even a lot cheaper than its Intel-based competitors.
These ancient APUs could be old unsold inventory being written off which meant fire sale prices and yet the price of these mini PCs are not much cheaper than competition.
