Quad-core 635 is the third standard-power processor of the Athlon II X4 family. This CPU is clocked at 2.9 GHz, or 300 and 100 MHz higher than models 630 and 620 respectively. The Athlon II 635 processor was introduced in January 2010 along with dual-core 255 and triple-core 400 CPUs, and it has the same Thermal Design Power and other thermal and electrical characteristics as other standard-power quad-core Athlon IIs. The 635 is the last quad-core model that used original C2 core stepping. The next standard-power microprocessor with model number 640, released in May 2010, had newer C3 core revision.
