Intel P6
From TPU Reference
relsitr The P6 microarchitecture is the sixth generation x86 microprocessor architecture of Intel, released in 1995. It was succeeded by the NetBurst microarchitecture in 2000, but eventually it was revived in the Pentium M line of microprocessors. The successor to the Pentium M variation is the Core.

From Pentium Pro to Pentium III
The P6 architecture lasted three generations from the Pentium Pro to Pentium III, and was widely known for its low power consumption, excellent integer performance, and relatively high instructions per cycle (IPC). When the NetBurst (P68) architecture was conceived with Willamette, which had relatively low IPC and less efficient overall design both in terms of power consumption and throughput efficiency, the P6 line of processing cores were widely thought to be abandoned.
Revived architecture in Pentium M (Banias and Dothan)
However, it was soon realized that the new NetBurst core was not suitable for mobile computing which required a cool and efficient core, and sometimes the NetBurst Thermal Envelope reaches very high levels (such as 115W of the Prescott revisions); and hence an improved version of the P6 core was revived, and brought back in the form of the Pentium M family, with some modifications.
