Apple has announced a Dual-1.8GHz version of the Power Mac G5, and cut the price of its entry-level single-1.6GHz Power Mac.

The new model offers dual-1.8GHz PowerPC processors, each with an independent 900MHz frontside bus that Apple claims "provides for more than 14GBps of bandwidth for fast throughput to main memory".

The G5 addition reflects the popularity of dual-processor models. Apple vice president of hardware product marketing Greg Joswiak said: "Our customers told us loud and clear that they love dual processors, so now two of the three Power Mac G5 models feature lightning-fast dual processors."

The Power Mac G5 line-up now includes three models: dual-processor 2.0GHz and 1.8 GHz machines, and a single-processor 1.6GHz model.

The company has also lowered the price of the single-processor 1.6GHz. Joswiak added: "With the entry-level model now starting at just £1,399, the Power Mac G5 line-up is more affordable than ever."

The dual-processor 1.8GHz G5 costs £1,899, and the price of the single-processor 1.6GHz model has been reduced from £1,549 to £1,399.

The dual-2Ghz Power Mac G5 remains £2,299. All prices including VAT.

Upon the G5's launch in June Apple claimed it was the "world's fastest personal computer", a claim recently dismissed as being "misleading" by UK TV-ads watchdog ITC .

Apple said its G5s offered the world's highest system bandwidth, highest bandwidth memory, and the fastest PCI interface available on a desktop.
