Page "Silicon Graphics" Paragraph 53

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 use a cluster architecture.

This is a departure from the pure NUMA architectures of the earlier Itanium and MIPS servers.
