I was looking at Motorolas website for G5 info (I know, it's not going to be there, I can still hope though ) Starting from our guess that the G5 is going to be related to the MPC8540 I looked for info on it. I found this : http://www.motorola.com/mediacenter/news/detail/0,1958,568_322_23,00.html Some of the more interesting stuff "The MPC8540 integrates dual gigabit ethernet controllers, a 10/100 controller, a 64-bit PCI-X controller operating at up to 133MHz, a DDR memory controller, a 4-channel DMA engine, a multi-channel interrupt controller and a DUART serial interface." DDR, PCI-X, and gigabit would work great for a new powermac. Anyone know what a "DUART serial interface" is? "The MPC8540 integrates 256KB of on-chip L2 cache, a coherency module that connects the core and memory controller to processor peripherals, and introduces a revolutionary non-blocking crossbar switch fabric called OCeaN (On-Chip Network). Leveraging the concepts of the RapidIO interconnect standard, OCeaN enables full duplex port connections at 128Gb/s concurrent throughput and independent per port transaction queuing and flow control. " "MPC8540 will be manufactured using the advanced HiPerMOS 7 (HiP7) 0.13-micron copper fabrication process technology." "600MHz - 1GHz, with power consumption expected to be 6.5W at 800MHz" "As the first RapidIO-enabled processor, and first processor to utilize the powerful e500 core" I wonder what other products will use the e500 core? G5, anyone? "About Motorola's e500 Core Announced in June 2001, Motorola's e500 high performance core is the first core from Motorola to implement the enhanced PowerPC "Book E" instruction set architecture."
