Short answer: A VPS is a virtual slice of a physical server with guaranteed RAM and shared CPU; a dedicated server is the whole physical machine. Choose a dedicated server for sustained heavy CPU, large RAM or compliance needs; otherwise a VPS is cheaper and far quicker to scale.
VPS vs dedicated server explained
A dedicated server gives you all the cores, memory, disks and network port of one machine, with no neighbours and full hardware control, including RAID choices and the BIOS. It takes hours to days to deliver, upgrades mean a hardware swap, and prices start around $60 per month for older hardware.
A VPS shares a host with other customers but isolates memory and disk. It provisions in minutes, can be resized and snapshotted, and costs a few dollars a month. Dedicated-CPU VPS plans narrow the performance gap by reserving cores for you.
Rules of thumb: below about 16 vCPU and 64 GB of RAM a VPS is usually the better deal; above that, or when you need consistent disk I/O for big databases, GPUs, special hardware or single-tenant compliance, rent a dedicated server.

Frequently asked questions
Is a dedicated server more secure than a VPS?
It removes hypervisor-level risks from other tenants, but most breaches come from the software you run, which is the same on both.
