Toshiba's 18.4-inch Qosmio G55 laptop uses a quad-core processor--but not the Intel or AMD variety.
The "Quad-Core HD Processor" used in the Qosmio G55--due mid-July--is based on the SpursEngine which is derived from the Cell Broadband Engine, a multicore chip architecture jointly developed by IBM, Sony, and Toshiba. The Cell architecture, in turn, is derived from IBM's Power Architecture. Today, IBM uses the Cell processor in a line of blade servers.
The four processing elements inside the chip have a clock frequency of 1.5GHz, while boasting a relatively low power envelope of 10 to 20 watts. Typical mobile Intel processors have a power envelope of 35 watts.
The SpursEngine can deliver up to 48 GFlops (billion Floating point operations per second) or 12GFlops per processing element. Every element has 256KB of integrated memory, according to Toshiba. And the processor excels at high-definition video encoding and decoding of MPEG-2 and H.264 (MPEG-4) streams.
