As I was thinking this would happen but kept quiet about it for fear of getting flamed down and burnt alive.
The X2 4000+ is Socket AM2 only; other X2s are available for both interconnects. The FX-62 is available in both AM2 and 939 forms. Curiously, the single-core 4000+ is only available in Socket 939 form, according to AMD's website.
In other words, it not only lacks support for DDR 2 SDRAM and hardware-enabled virtualisation, but it also consumes more power. AMD's processor specs show the Socket AM2 chips consuming less power than their Socket 939 equivalents. For example, two Socket AM2 Athlon 64 X2 4800+ CPUs are available, consuming 89W and 65W, respectively. The latter is labelled "energy efficient" by AMD. The Socket 939 X2 4800+ consumes 110W. Except for the FX-62, which has a Thermal Design Power (TDP) of 125W (Boardy - OOOO Lovely and toasty then
)
Interesting move there.
