According to AppleInsider, Steve Jobs will announce and most likely will be showing the new PowerMac G5 later this month at Apple's annual developers conference.

The new Power Mac G5s will sport a completely new motherboard design utilizing DDR 400 RAM as well as AGP 8x graphics, FireWire 800 (FireWire 2), and USB 2.0, sources said. "In the box" connectivity among the news systems is based on Hypertransport -- a universal chip-to-chip interconnect developed by AMD and partners -- which provides 64-bit addressing and will replace Apple's multilevel bus architecture found in current systems. This royalty-free technology sports a low manufacturing cost and is capable of transferring data at up to 12.8 Gigabytes per second.

Despite of early rumours that Apple was looking into AMD's 64bit technology for the new Macs, it's almost a fact that they will make use of IBM's 64 bit PPC 970 processor instead. Last but not least, although G5s are expected as soon as July, a new Macintosh OS 'Panther' that takes advantage of the 64bit system won't be available until this September.
