Mercury News: Microsoft leaks details on Xbox Next "For gamers, the new Xbox will be impressive, giving them the ability to play fast-action, realistic 3-D games on a high-definition TV set. Microsoft's emissaries have told industry developers and publishers that the next Xbox will be ready to launch in fall 2005 with the following specifications:
• Three IBM-designed 64-bit microprocessors. The combined power of these chips means the Xbox Next will have more computing power than most personal computers. The chips are used in Apple Computer's high-end G5 PowerMac machines now.
• A graphics chip designed by ATI Technologies with speeds much faster than its upcoming R400 chip for the personal computer. This chip will help the next Xbox to display games with the resolution of high-definition TV.
• Compatibility with the original Xbox, which is based on Intel and Nvidia chips, isn't guaranteed. Microsoft is concerned it would cost too much money in hardware or in licensing fees to enable the Xbox Next to play old Xbox games. This is risky in part because Sony's strategy has been to maintain compatibility with its old consoles."
