AMD drops prices of Athlon II and A-Series processors
Nov 06, 2012
: Last month DigiTimes reported on upcoming price reductions of
older generation of AMD APUs. According to their sources, AMD was
going to reduce prices of socket FM1 processors by as much as 35%.
Yesterday AMD updated their official price list, and posted new prices
of A-Series microprocessors, however the cuts were not as big as
AMD quietly introduces two Athlon II X4 CPUs
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.
