ARS Technica posted an interesting little blurb on the death of Socket 939.
If you have been thinking about building or upgrading an AMD system, now's the time. The CPU maker is putting some of its more popular CPUs out to pasture in the next few months, including all of its Socket 939 lineup.
It was just one month ago that the company launched its new Socket AM2 CPUs. Socket AM2 brings support for DDR2 along with a a couple of new chipsets from NVIDIA and ATI. When it launched, the company introduced two new flagship CPUs, the Athlon 64 X2 5000+ and the Athlon FX-62, along with a number of CPUs from the Socket 939 lineup such as the Athlon 64 X2 4000+ which were moved to the new pin-out.
Now that Socket AM2 is here, many parts of AMD's CPU lineup will be disappearing"”some quite soon. The single-core Athlon 64 3700+ and 4000+ will be discontinued in early July, with only the higher-end Athlon 64 X2 4800+ lasting past the end of the year. In addition, a number of Socket 754 CPUs (e.g., Semprons) will be discontinued as well. The Semprons should be available through the end of 2006 at least, with the Sempron 3000+ to be manufactured through the first quarter of 2007.
