That really depends on which market segment you look at. Intel does have a faster home/office/single socket cpu but AMD still has better products in the multi-socket range.
I don't see Cray switching to Intel anytime soon.
oh yea...?
Conclusion
It took a few years, which is normal for any architecture redesign, but we feel Intel has finally created a product that is not just competitive to the AMD Opteron. Woodcrest outperforms all of the competition in 2-way configurations, and it does so with lower power consumption. This combination leads to better Performance/Watt in all tested situations. Woodcrest not only outperforms it's predecessor by over 100% in Performance/Watt, but it outperforms Opteron by as much as 60% in Performance/Watt. In terms of straight performance the Woodcrest led the way by anywhere from 18 to 35% at higher system loads. We feel that Intel has the vision to continue this trend, as they have a clear roadmap for next year and beyond. Expect to see even further gains in 2007. How those parts will compete with future AMD products is unknown, but we have competition and that is always good for the consumer.
