UEFI is essentially a tiny operating system that runs on top of the PC's firmware, and it can do a lot more than a BIOS. It's not just a BIOS replacement, either.

With a traditional BIOS, you have to be sitting in front of a physical computer to configure it. It can support networking features right in the UEFI firmware itself, which can aid in remote troubleshooting and configuration. It supports Secure Boot, which means the operating system can be checked for validity to ensure no malware has tampered with the boot process. Many PCs still ship with text-mode UEFI settings interfaces that look and work like an old BIOS setup screen. It also means that UEFI setup screens can be slicker than BIOS settings screens, including graphics and mouse cursor support.

UEFI can run in 32-bit or 64-bit mode and has more addressable address space than BIOS, which means your boot process is faster.
