Note that Ising computers are quite special-purpose machines and can't (easily) solve general purpose computing problems.
The most known/hyped of them a couple of years ago was the D-Wave "quantum computer".
The machines can (approximately) solve useful NP-hard problems like routing, scheduling, resource/portfolio allocation, protein folding etc.
