Inside Intel's Penryn
Published: 12 Nov 2007
Conclusion
Penryn is faster. It's also better at power consumption — a lot better. But perhaps the most important aspect of the design is that it demonstrates continual improvement compatible with the existing code base, with plenty of opportunities for the future. It has also been delivered to spec, on time and in quantity.
Intel's tick-tock design rule may yet have problems of its own in the future, due to its very rigid nature and far-reaching predictive power. But for now it seems to be performing so well that the problems it brings are entirely for the competition.
