XPS ("Extreme Performance System") is a line of consumer-oriented high-end laptop and desktop computers manufactured by Dell since 1993, formerly part of Dimension, and since 2008 a standalone brand.

In the early 1990s, Dell primarily targeted its products at businesses rather than consumers. In early 1993, Dell executives met to address how to pursue the emerging consumer market in the US (led by Gateway 2000, later known as Gateway), and decided to launch a new product line to compete with Gateway. At that time, Dell's annual revenue was less than $500 million, and founder Michael Dell was still directly involved in key decisions. Vernon Weiss, the product manager, led the project and managed product marketing, while Brian Zucker oversaw architecture and engineering.

In September 1993, the first two products in the XPS line were announced, initially as part of the Dell Dimension series. The first generation XPS systems were available in both desktop and tower configurations. The earliest known XPS PC, the Dell Dimension XPS 466V, was released in 1994. The new product line achieved commercial success, garnering significant media attention. For example, an XPS was featured on the cover of the October 1993 issue of PC/Computing.

From 1997 to 2001, the XPS line lost its leading position in the market as Dell steadily grew and the market continued to evolve over time. Dell then revamped the XPS line in 2005 to compete with Alienware (then a separate company) and Falcon Northwest. Correspondingly, Dell split its home desktop system into two lines (Dell Dimension and XPS), its consumer notebooks were also split into two lines (Dell Inspiron and XPS). Shortly thereafter, on March 22, 2006, Dell acquired Alienware, a move they had been considering since 2002. Alienware maintained its autonomy in terms of design and marketing, but access to Dell's supply chain management, purchasing power, and economies of scale lowered its operating costs. The new XPS line initially had the same specifications as those offered by the Alienware division.

In 2008, Dell introduced the "Studio XPS" line, which it marketed as a performance computer line, while Alienware was advertised for gaming. On June 2, 2009, the M18z gaming laptop was introduced as the first Alienware/Dell joint-branded system.

In January 2025, Dell announced its intentions to gradually phase out their existing lineup of computer brands in favor of a singular brand simply named as "Dell" as part of the company's shift towards the next generation of PCs with artificial intelligence capabilities. The XPS brand (as well as the Inspiron brand) would be supplanted by the Dell laptop line designed for play, school and work, which includes the Dell, Dell Plus and Dell Premium series.

The 2024 Dell XPS 8960 features Intel's 14th-generation i3, i5, i7, and i9 CPUs. It has two slots for DDR5 memory, for a maximum of 64 GB. This is the first time Dell refreshed this XPS desktop using the same name, but some internal changes.^{[citation needed]}
