They decided to base Pentium M on the P6 microarchitecture. Thus=2C the Pentium M was family 6=2C model 9=2C which was the same as orig= inally used by the cancelled Timna project=2C led by the same Mooly Eden. As it happened=2C Prescott turned out to have high heat output and power co= nsumption=2C and as a result=2C Tejas was cancelled=2C and the NetBurst arc= hitecture was abandoned and along with it the family 15. The Pentium M project came to the rescue and made the Pentium M core better= . By Core 2 Duo=2C the core had gained x86-64 support and thus was ready to= replace NetBurst on the desktop and server. It was family 6 model 15=2C wh= ich confused Solaris 64-bit that thought all x86-64 CPUs was family 15. Sin= ce they ran out of the 4-bit in the model=2C they then had to begin using t= he extended model field=2C 45nm Core 2 processors was extended model 1. Add= ing 15 and 1 yielded 16. In the meantime=2C AMD came out with it's first x86-64 processor called the= K8=2C which copied the family 15 used by the P4 processor. Because similar= things had not happened at AMD=2C AMD was forced to begin using the extend= ed family with the K10=2C which was extended family 1. Adding 15 and 1 yiel= ded 16=2C or family 10h=2C which was what it was often called by AMD.
