Anandtech reports from the IDF (Intel Developer Forum) that the new architecture will borrow the FSB and 64-bit capability from the Netburst architecture and the Power Optimizations from the Pentium M.

The basic integer pipeline appears to be 14 stages long, making it a significant decrease from the 31+ stage pipeline in Prescott and a slight increase from the 12 stage pipeline in the Athlon 64. Intel’s move to a much shorter pipeline will definitely decrease power consumption (as well as clock speed), but hopefully improve performance considerably.

Note that with a 4-issue core, the new processors will actually have a higher degree of ILP than AMD’s Athlon 64, and with a slightly deeper pipeline the CPU should be able to reach higher clock speeds than what AMD has been able to achieve. We’d expect that at 65nm these new cores could run as high as 3GHz in clock speed, but definitely not at the 4GHz+ levels that we currently have with the Pentium 4.

This is the right step for Intel. More parallelism will allow them to keep power consumption down and still allow for greater performance.
