DESC: With two dual-core processors, at speeds up to 2.5GHz per core, the Power Mac G5 Quad doubles the punch of its dual-processor predecessor. Do the math: Quad-core processing means four Velocity Engines and eight double-precision floating-point units for blistering performance of up to 76.6 gigaflops. That means you can manipulate mountains of images or miles of footage. Crunch enormous data sets. Encode HD video or high-bit-rate audio. All at speeds you never imagined possible.
