When the 360 hit the market last year there were widespread complaints about the system's sound and heat issues: it sounds like a small aircraft taking off, and the heat output can be substantial. Part of the reason for these two things is the size and complexity of the CPU, and the fact that it is fabbed using a 90nm die process. We've been looking forward to a process shrink that would bring the Xbox's CPUs down
to a tight 65nm process, but DigiTimes is now reporting that the switch
has been delayed into the middle of 2007, citing unnamed sources. With neither Microsoft nor Chartered Semiconducting Manufacturing willing to comment on the report, it must remain unverified.
