History
Predecessor(s)	Pentium

Intel Core is a line of multi-core (with the exception of Core Solo and Core 2 Solo) central processing units (CPUs) for midrange, embedded, workstation, high-end and enthusiast computer markets marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets.

The lineup of Core processors includes the low-end Core i3, mid-end Core i5, high-end Core i7, and enthusiast Core i9 series.

In 2023, Intel announced that it would drop the "i" moniker from their processor branding, making it "Core 3/5/7/9". The company would introduce the "Ultra" branding for high-end processors as well.^[1]
