XPS desktops are a family of consumer-oriented high-end desktop computers under the XPS brand, manufactured by Dell Inc..

Early models

XPS Hxxx series (1996/97) A system that came out circa 1996/97. It contained an Intel Pentium II (Klamath) CPU, EDO DRAM, and an i440FX chipset.

XPS Dxxx series (1997) A system that came out in 1997. It contained an Intel Pentium II (Klamath) CPU, SDRAM, and an i440LX chipset.

XPS Rxxx series (1998) A system that was introduced in 1998. It contained an Intel Pentium II (Deschutes) CPU, SDRAM, and an i440BX chipset.

XPS Txxx series (1999) A system that was introduced in 1999. It contained an Intel Pentium III CPU, SDRAM, and an i440BX chipset.

XPS Bxxx series (2000) A system that was introduced in 2000. It contained an Intel Pentium III CPU, 128 MB of RDRAM, an ATi RAGE graphics card, and an i820 chipset. An "r" suffix was used for Socket 370 versions, while no suffix was used for Slot 1 versions. Later models (especially the "R" series) had a built-in DVD drive.

XPS Gen 2 (2003) Included a Pentium 4 processor with Hyper-Threading Technology (3.4 GHz, 800 MHz Bus); Microsoft Windows XP Professional; 400 MHz dual-channel DDR SDRAM (400 MHz); Support for SATA and IDE hard drives; one AGP Slot; four PCI slots; Sound Blaster Audigy²; and Dell Wireless Keyboard and Mouse. The video card included was ATI Radeon 9800 Pro (AGP x8). It was powered by a 460-watt proprietary power supply and featured decorative LEDs on the front of the case which the user could change the colors of in the BIOS.

XPS Gen 3 (2004) The base configuration had a Pentium 4 processor at a speed of 3.0 GHz or higher; 512 MiB of DDR, 400 MHz RAM; a single 80 GB 7200 RPM hard drive; an ATI Radeon X800 XT graphics card; and a Sound Blaster Audigy² audio card. It came pre-installed with Windows XP Home Edition.

XPS Gen 4 (2004)

The base configuration had a Pentium 4 processor at a speed of 3.0 GHz or higher; 512 MiB of DDR2, 533 MHz RAM; a single 160 GB 7200 RPM hard drive; an NVIDIA GeForce 6800 graphics card; and a Sound Blaster Audigy² audio card. It came pre-installed with Windows XP Home Edition.

XPS Gen 5 (2005) Used a Pentium 4 HT processor with 512 KiB, 1 MiB, or 2 MiB of L2 Cache. It could support up to 8 GiB of DDR2 memory at 533 MHz or 667 MHz.

XPS 200 series XPS 200 (2005) The XPS 200 used a small-form-factor case, making it much smaller than the XPS 400. It was aimed at being a 'low-impact machine', meaning that it was intended to blend in better with a room's features. Despite the XPS name it was more of a multimedia computer than a gaming machine. It did not use full-size PCI slots. This model was available from late 2005 to the end of the third quarter of 2006, before being replaced by the XPS 210.

XPS 210, aka Dimension 9200C (2006) The XPS 210 replaced the XPS 200 in 2006, with an upgrade to the Intel Core 2 Duo processor line. It was also sold as the Dimension 9200C outside of the United States. Alongside the 9200 (a rebranded XPS 410) it was the final desktop in the Dimension line, which effectively made an XPS unit the last in the Dimension family.

XPS 400 series XPS 400, aka Dimension 9150 (2005) This model was available during late 2005 and the first half of 2006. It was replaced by the XPS 410, which was nearly identical except for an optional Intel Core 2 Duo processor and slightly different audio and video card options. It was rebranded outside the United States as the Dimension 9150, which was replaced with the Dimension 9200.

XPS 410, aka Dimension 9200 (2006) The former intermediate model of the XPS series and bigger brother to the Dimension E520. It featured a base configuration of an Intel Core 2 Duo processor. A 2.4 GHz Core 2 Quad was also available as an option. Other base options included the NVIDIA GeForce 7300LE; 7200RPM SATA-300 hard drive; and dual-channel DDR2 RAM. The case was nearly identical to that of the Dimension E520, with an additional 3.5-inch drive bay which made the case physically taller. The power supply was also slightly more powerful than the Dimension E520 (375 W vs 305 W, respectively and has an added six-pin PCIe power cable). The XPS 410 replaced the XPS 400, and was itself replaced by the XPS 420.

XPS 410 units were also sold as the Dimension 9200 in some countries. Released in 2006, the Dimension 9200 (as well as the Dimension 9200C, which was a rebranded XPS 210) was the final desktop in the Dimension line, effectively making an XPS unit the last in the Dimension family.

XPS 420 (2007) This model featured similar components to the XPS 410, but it used different case designs and had new features. This was Dell's media-based computer featuring the Dell Xcelerator (a simple and effective Video Recorder), and an LCD screen in the case, running Windows Vista SideShow. As usual with the 4xx line of XPS, it did not allow for SLI Graphics. The XPS 420 added support for 45 nm Core2 Duo/Quad/ and Extreme CPUs up to the QX9650.

XPS 430 (2008) Similar to 420, but with DDR3 RAM and without the LCD on the computer chassis.

XPS Studio 435/435T/435MT These model numbers were used for the first Studio XPS desktops (see below).

XPS 600 series XPS 600 (2005) Originally the flagship, prior to the introduction of the XPS 700 series, the XPS 600 featured an Intel dual-core Pentium D 950 processor; dual Nvidia GeForce 7900GTX in SLI mode; a 7200 RPM SATA hard drive; and dual-channel DDR2 RAM. The case design had not changed significantly over the past several generations, with the large aluminum plate on the front.

XPS 630, aka 630i (2008) The XPS 630/630i filled the gap between the media-oriented XPS 420/430 and the high-end XPS 730x. It featured a Dell-modified Nvidia NForce 650i chipset which supported both SLI and CrossFire configurations, but lacked ESA certification (the only ESA-certified component was Dell's "Master Input/Output" (or "MIO") printed circuit board). At one time it came standard with an Intel Core 2 Quad Q6600 CPU and dual Nvidia GeForce 8800GT graphics cards.

There was no physical difference(s) between the 630 and the 630i. A marketing concept applied an "i" suffix to designate systems installed with an Intel chipset, with intention to use an "a" suffix for systems with an AMD chipset, but since Intel-based chipsets were the only models ever sold, this designation held no significance. Instead, AMD-based units were later sold under the 625 model number.

Issues with the XPS 630 included problems with the chassis fan control; chassis LED lights; non-shipment of the LightFX 2.0 lightshow control software; limited PCIe slot configuration (8,8,1,1; OEM Nvidia 650i SLI motherboards also offered the 16,1,1,1); constant HDD LED activity; and a reliability issue due to a problem inherent in the Nvidia 650i SLI chipset that could surface when overclocking with 4 or more gigabytes of RAM. The problems resulted in PC PRO revoking their 'Recommended' award. The July 22, 2009 release of a Softex Media Plug-in provided some of the features originally advertised in LightFX. BIOS updates were issued to patch the constant HDD LED activity. Some owners bypassed the aforementioned problems by swapping out the Dell-modified NVidia 650i motherboard with OEM motherboards such as the EVGA nForce 780i SLI FTW. The motherboard had 8 lanes wired for each PCIe slot, which could restrict performance if using a single high-performance graphics card. Performance was equivalent to other systems with NVidia 650i chipset motherboards when using two graphics cards in SLI mode.

XPS 625 (2009) A version of the XPS 630 but with AMD Phenom II chips and ATI Graphics.

XPS 700 series XPS 700 (2006)

Targeted at the gaming community, the XPS 700 featured the Intel Pentium D Extreme processors with speeds up to 3.7 GHz with dual Nvidia GeForce 7900 GTX GPUs in SLI mode; a 7200 RPM SATA hard drive; and dual-channel DDR2 RAM. It was advertised as being overclockable but actually was not. Dell would later offer a free upgrade program, providing an XPS 720 motherboard to XPS 700 owners so that these machines could be overclocked with the BIOS.XPS 700 Motherboard Exchange Program The aluminum case featured a distinctive "leaning" design. It used a significantly larger power supply (750 W or 1 kW) than the smaller 200/400/600 series models to accommodate higher-end video cards and overclocked CPUs. Unlike its forerunners, it used a BTX motherboard, thereby limiting possible upgrades.

XPS 710 (2006) The XPS 710 featured the new Intel Core 2 Duo and Core 2 Extreme processors, as well as Core 2 Quad processors. Other features included dual NVIDIA GeForce 7950 GX2 in Quad SLI mode; a 7200 RPM SATA hard drive; and dual-channel DDR2 RAM. Like the 700 it was eligible for the 720 model motherboard upgrade program, though not for free.

XPS 720, XPS 720 H2C (2007) The XPS 720 was announced on November 24, 2007. A H2C edition was available, along with a Red Special Edition. All came with a 1 kW power supply.

The H2C edition included dual-stage radiator cooling technology, and a motherboard capable of overclocking its quad-core Intel Core 2 Extreme QX6800. It came standard with dual NVIDIA GeForce 8800GTX cards running in SLI for $6,780. It also used slightly higher quality parts than other XPS classes, and at the time it was one of the most powerful pre-built PCs available by a significant margin.

XPS 730 H2C (2008) Like the 720 H2C edition, the 730 H2C used H2Ceramic cooling, a high-performance cooling system, which was ideal for gaming and overclocking. Its motherboard, the NVIDIA NForce 790i Ultra, was capable of overclocking its quad-core Intel Core 2 Extreme QX9770 up to 3.64 GHz. It used Dual channel DDR3 SDRAM.Dell XPS 730 Desktop Gaming PC – Product Details There was also a choice of colors at some outlets. The basic model specs were an Intel Core 2 Extreme Processor QX9650 (3.46 GHz Overclocked); dual 1 GiB ATI Radeon 3870 X2 Crossfire X graphics cards; 2 GiB RAM; and 1 TB 7200rpm dual HDDs. The base price in the UK was £2,499.Dell XPS 730 Desktop Gaming PC – Product Details

XPS 730X, XPS 730X H2C (2008) Released on November 16, 2008, the XPS 730X was essentially an XPS 730 with a new Intel Core i7 CPU and Intel X58 chipset. The XPS 730X H2C was a higher-end version which used H2Ceramic cooling and often shipped with factory-overclocked Core i7 Extreme Edition processors. The 730X also integrated Alienware's AlienFX and a new theatre lighting system. It supported Tri-Channel 6 GiB of DDR3 RAM. The graphics card was either a dual or single NVIDIA GeForce GTX 285, or a single ATI Radeon HD 4870 X2. It originally shipped with Windows Vista, but eventually offered Windows 7 near the end of its availability.

Dell internally discontinued these models in its US online store on August 1, 2009, and cancelled any remaining orders after August 15, 2009. It has been mentioned that this was done to focus more attention on customers seeking gaming computers, such as Alienware.

XPS Tower 8000 series

XPS 8100 (2010) Model 8100 was released in 2010. It was a mid-range, all-purpose PC aimed at home users. It had a Core i5-650 processor, 4 GiB of DDR3 RAM, 1 TB of storage space, and an NVIDIA GTS 240 graphics card as standard.

XPS 8300 (2011) Model 8300 used Intel H67 socket 1155 based Sandy bridge CPUs, such as the i5-2320 and i7-2600K, and an 0Y2MRG (DH67M01 TB0420) motherboard.
