IBM will announce a new G3 processor at the Microprocessor Forum that runs from October 15 to 19 in California.

The five-day event will debut the 750FX. This new G3 chip will improve on the power consumption, performance and price of its predecessors the 750CX and 750CXe, announced earlier this year and used in Apple's iBook and iMac machines.

IBM has said that the 750FX would feature improved bus utilization, memory management and reliability.

The 750FX is expected to continue the strategy of implementing an on-die cache. The 750CX and 750CXe designs have a 256KB on-die cache, which allows chips to be designed without external cache connections – permitting ease of packaging and lower pricing.
