News

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 expected.

Phenom II and Athlon II CPUs to EOL in Q4 2011

Sep 26, 2011: Fudzilla reported today that large number of AMD CPUs, built on 45nm process, will be end-of-lifed in this quarter. This affects many Athlon II X2, X3, X4, Phenom II X2, X4, X6 and Sempron processors. AMD already stopped orders for some models, while the rest of the processors can still be ordered until the end of this quarter.

AMD launches A-Series and the first 32nm Athlon II X4 CPUs

Aug 17, 2011: Earlier this month, we reported on pre-order prices of several forthcoming AMD A-series and Athlon II X4 microprocessors, built on new 32nm Llano core. Based on these prices, we projected that the A6-3600 and A8-3800 APUs will cost the same as A6-3650 and A8-3850 models, or very close to them. We also estimated $90 - $100 price for triple-core A6-3500, and $80 - $90 range for the Athlon II X4 631. AMD today added these processors to official pricelist, and the prices are slightly better than we estimated.

Pre-order prices of upcoming Llano processors

Aug 08, 2011: Launched one month ago, AMD A-Series currently consists of two Accelerated Processing Units (APUs), A8-3850 and A6-3650. Both microprocessors have fixed core frequency, 2.9 GHz and 2.6 GHz respectively, and 100 Watt TDP. This quarter, AMD is going to introduce several additional A4-, A6- and A8-Series SKUs.

Athlon II and Sempron-branded Llano CPUs surface on Bisotar website

Aug 05, 2011: Earlier this year AMD introduced Llano processors, manufactured on 32nm process, and based on enhanced "Stars" (K10) microarchitecture. First two AMD Llano microprocessors were launched more than a month ago, while several other APU models will be available later this quarter, and in the 4th quarter. Depending on incorporated features, all current and upcoming Llano models are branded as "A-Series" or "E2-Series".
