PowerPC 970
When Apple introduced the Power Mac G5, it stated that this was a five-year collaborative effort, with multi-generation roadmap.This forecast however was short-lived when Apple later had to retract its promise to deliver a 3 GHz processor only one year after its introduction.The PowerPC 970 can fetch and decode up to eight instructions, dispatch up to five to reserve stations, issue up to eight to the execution units and retire up to five per cycle.The buses also carry addresses and control signals in addition to data so only a percentage of the peak bandwidth can be realized (6.4 GB/s at 450 MHz).Furthermore, the northbridge chips available to interface the 970FX to memory and other devices were not designed for portable computers, and consumed too much power.Its minimum (idle) power was much too high, which would have led to poor battery life figures in a notebook computer.[citation needed] IBM announced the PowerPC 970MP, codenamed "Antares", on July 7, 2005, at the Power Everywhere forum in Tokyo.Its features were a 533 MHz DDR2 controller that supported up to 8 GB ECC memory, a 8x PCIe bus, integrated four-port Gigabit Ethernet with IPv4 TCP/UDP offloading, USB 2.0 ports, a Flash-interface.
