The P4 series does.(pentium 4s are based on netburst)
I'm not so sure about those which belong to the centrino line. Those intel chips made it into laptops, PPC 970's didn't. AFAIK the current P6 architecture based chips are quite cooler than their PPC bretheren.
But even then, there are P4 laptops. No 970 laptops.(that I've seen)
All of the next generation Intel CPUs will be based on the mobile chip design. Favoring throughput instead of clock speed -- following AMD by some years.
