===Switch to Xeon===
Although SGI continued to market Itanium-based machines, its more recent machines were based on the Intel [[Xeon]] processor. The first Altix XE systems were relatively low-end machines, but by December 2006 the XE systems were more capable than the Itanium machines by some measures (e.g., power consumption in FLOPS/W, density in FLOPS/m<sup>3</sup>, cost/FLOPS). The XE1200 and XE1300 servers used a cluster architecture. This was a departure from the pure NUMA architectures of the earlier Itanium and MIPS servers.

In June 2007, SGI announced the Altix ICE 8200, a blade-based Xeon system with up to 512 Xeon cores per rack.<ref>{{cite press release| title = SGI Unveils Ultra-Dense SGI Altix ICE Blade Platform Purpose-Built for High-Performance Computing| publisher = SGI| date = June 26, 2006| url = http://www.sgi.com/company_info/newsroom/press_releases/2007/june/altix_ice.html| access-date = November 26, 2007| url-status=dead| archive-url = https://web.archive.org/web/20071022072329/http://www.sgi.com/company_info/newsroom/press_releases/2007/june/altix_ice.html| archive-date = October 22, 2007}}</ref> An Altix ICE 8200 installed at New Mexico Computing Applications Center (with 14336 processors) ranked at number 3 on the TOP500 list of November 2007.
