I checked these "new" prices (unconfirmed by AMD of course) against some previously published price data (from other web sources) in Q2 and Q3-2012. Now, one might argue that the older price data was irrelevant anyway because it was all speculation. But, as others have pointed out, AMD appears to be adjusting quickly to market forces. Good for them!
FX8350 (old data $253) -- new price $200 (I just rounded up to 200, it could be $19x). // 21% reduction
(8c, 8MB L2, 8MB L3, 125W, 4.0->T4.2Ghz)
FX8320 (old data $242) -- new price $175 // 27.7% reduction
(8c, 8MB L2, 8MB L3, 125W, 3.5->T4.0Ghz)
FX6300 (old data $175) -- new price $135 // 23% reduction
(6c, 6MB L2, 8MB L3, 95W, 3.5->T4.1Ghz)
FX4300 (old data $131) -- new price $125 //4.6% reduction
(4c, 4MB L2, 8MB L3, 95W, 3.8Ghz->T4.0Ghz)
Clearly, the FX4300 took the smallest *percentage* price hit, while the FX8320 got the biggest percentage haircut.
IMHO, the FX6300 is the most tempting of the lot, not only because of the attractive price but because of the 95W TDP.
