News

AMD adds Athlon II X2 280 CPU, drops some prices

Feb 01, 2013: Earlier this week XBiT laboratories published two slides, showing updated AMD desktop lineup. On the lower end of that lineup AMD had FX-4130 microprocessor, and the mid- and high-performance products were Piledriver-based FX-4300, FX-6300, FX-8320 and FX-8350 CPUs with "Vishera" core. The most intriguing was that the FX-4130 had box part number FD4130WMHKBOX, which was different from previously launched FX-4130 CPU with FD4130FRGUBOX box SKU.

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.

AMD cuts prices on older desktop models

Dec 07, 2010: With the launch of three new desktop processors today, AMD also dropped prices on many older models. Majority of price cuts were insignificant, typically in the range from 3% to 10%. The price of one microprocessor, Phenom II X4 970, was increased by $5, or by about 3%.

AMD updates Athlon II and Phenom II lineups

Sep 21, 2010: Today AMD launched 6 new desktop models, which span across six different Athlon II and Phenom II families. Also, two budget-class models, Sempron 145 and Athlon II X2 220, are now available as boxed processors. The new processors are offered in a wide range of prices, from budget dual-core Athlon II 265 at $76 and up to high-performance Phenom II 1075T at $245.

New AMD CPUs show up in retail stores

Sep 18, 2010: A few days left before AMD officially announces new refresh of Athlon II and Phenom II microprocessor line-ups. In this refresh AMD is going to introduce new dual-, triple- and quad-core Athlon II CPUs with model numbers 265, 450 and 645, and three Phenom II microprocessors - dual-core 560, quad-core 970, and six-core 1075T.

New AMD desktop CPUs are on the way

Aug 11, 2010: AMD is getting close to introducing a new wave of Athlon II and Phenom II desktop microprocessors. This time we will see a variety a CPUs from single-core Sempron 145 to six-core 1075T.

AMD boxed desktop processors for Q3/Q4 2010

Jul 28, 2010: We recently stumbled upon public AMD dealer product training document, that contains limited information about planned desktop microprocessors for the rest of this year. The document doesn't show any new processor models besides those that are already known from our stories, and from stories posted by other hardware news sites. Nevertheless, we decided to post two pages from the document as they confirm impending release of new Phenom II, Athlon II and Sempron models.

AMD Athlon II and Phenom II CPUs planned for the third quarter

Jul 20, 2010: AMD already refreshed their lines of desktop Athlon II and Phenom II families two times in 2010. First time it happened in January, when AMD released standard-power Phenom II X2 and Atlhon II microprocessors, and second time it was at the end of April and in May, when AMD introduced 6-core Phenom II processors, and updated the whole line of Athlon II CPUs. In the third quarter AMD plans an incremental upgrade for many energy-efficient and standard-power Athlon II CPUs, and will introduce a few Phenom II models.
