IBM plans to double the performance of their PowerPC chip to 4 to 5 Ghz. Rather than fitting more smaller transistors they plan on placing an insulator under the silicon measuring 500 atoms thick. My hats off to IBM if they can do this. Though I wonder if they will actually achieve it considering that PowerPc run very hot, my brother lives in Spokane and leaves his window open with the computer is on in the dead of winter, so I am not going to get too excited, but i will be 'catiously optimistic'.
