Coming to the Pegasos this summer will be processor cards sporting the Motorola 7447 running at 1 GHz or more. The 7447 is the latest in the 4th generation (G4) PowerPC lineup from Motorola, offering an improved performance base over the previous generation (G3) series of processors.

In addition to a larger cache, the 7447 offers more pipelines, an improved front side bus (FSB) and most of all, a SIMD unit called the Altivec. What Altivec offers is a dedicated on-chip vector engine, capable of delivering over a Gflops (billion floating point operations per second) while remaining affordable to the average user.
