Then Mooly Eden started the Pentium M project.
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.

Windows 7: I wanted more reliable=2C now it's more reliable. Wow!
