ThinkStation is a brand of professional workstations from Lenovo announced in November 2007 and then released in January 2008. They are designed to be used for high-end computing and computer-aided design (CAD) tasks and primarily compete with other enterprise workstation lines, such as Dell's Precision, HP's Z line, Acer's Veriton K series, and Apple's Mac Pro line.

HP Z is a series of professional workstation computers developed by Hewlett-Packard. The first-generation desktop products were announced in March 2009, replacing the HP 9000 xw series. The product line expanded to mobile with the announcement of ZBook in September 2013, replacing HP's EliteBook W-series mobile workstations. The Z workstations mainly compete against Dell's Precision workstations, Lenovo's ThinkStation and ThinkPad P series workstations, as well as Apple's Mac Pro and MacBook Pro.
