Central Processing Unit
The PS3 uses the Cell microprocessor, which is made up of one 3.2 GHz PowerPC-based "Power Processing Element" (PPE) and six accessible Synergistic Processing Elements (SPEs). A seventh runs in a special mode and is dedicated to aspects of the OS and security, and an eighth is a spare to improve production yields. PlayStation 3's Cell CPU achieves a theoretical maximum of 230.4 GFLOPS in single precision floating point operations and up to 100 GFLOPS double precision using iterative refinement for the solution of linear equations. The PS3 has 256MB of Rambus XDR DRAM, clocked at CPU die speed.

Famous quotes containing the words central and/or unit:
“But when the self speaks to the self, who is speaking?—the entombed soul, the spirit driven in, in, in to the central catacomb; the self that took the veil and left the world—a coward perhaps, yet somehow beautiful, as it flits with its lantern restlessly up and down the dark corridors.”
—Virginia Woolf (1882–1941)
“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
