In short, the difference is speed. Our regular VPS platform delivers enough computing performance for most business needs, at a lower price. The platform is built on incredibly reliable, high-quality hardware and a battled hardened technology stack we've been running for well over a decade. High Performance Virtual Servers are built for intensive computing. High-spec hardware includes Ryzen 9 CPUs (which are so new that they have only been available in our Dedicated Servers for a few months), and the platform is managed via a newly-built virtualisation layer. It’s an entirely different platform built for a more demanding audience.
