News
Feb 08, 2012: With the launch of "Llano" microprocessors in the middle of
last year, it seemed like AMD was going to retire their older Athlon II and
Sempron brands, that are commonly associated with mid-class and budget
K10-based processors. Despite of introduction of new "A-Series" and
other "-Series" families, the company continued to use "Athlon II" and
"Sempron" names for "Llano" products, that didn't have on-chip GPU. The
first Athlon II branded Llano model for socket FM1,
quad-core 631 with 2.6 GHz frequency, was
launched last summer. It was followed by
Athlon II 651 in November. Yesterday AMD
added another two Athlon II CPUs to AMD product database.
