The AMD Phenom family of processors was designed as a flexible family of chips avail-
able with 1-6 K10 cores in a single die. These include the Phenom, Phenom II, Athlon
II, and some models of the Athlon X2 and Sempron processors. The initial versions used
Socket AM2+, which included support for DDR2 memory. Later versions used Sockets
AM3 and AM3+, which support DDR3 memory. Figure 3.39 illustrates a Phenom II X6
processor for Socket AM3.
Figure 3.39 The Phenom II X6 conceals six cores and memory controllers for both DDR2 and DDR3
memory beneath its protective metal spreader plate.
The Phenom X3, X4 and Athlon X2 processors were made on a 65nm process, whereas
the Phenon II, Athlon II, and Sempron 1xx processors use a smaller 45nm process, result-
ing in a smaller die with overall lower power consumption and higher performance. Fig-
ure 3.40 illustrates the interior design of the Phenom II X6 processor.
