A representative for Advanced Micro Devices said that the listing of unannounced AMD Athlon 64 X2 5000+ processor in an official document was a “mistake” and should not be “there”. He denied to comment regarding the specifications or product positioning.

“It’s a mistake, shouldn’t be on the sheet,” said Damon Muzny, a spokesman for AMD. “It’s a typo for certain, just not sure what the mistake was yet. As there isn’t a 5000+ part for 939 or AM2 yet, I can’t give an official answer if that part is to come out in the future.”

Recently released official document of AMD titled “AMD Athlon 64 Processor Power and Thermal Data Sheet” lists AMD Athlon 64 X2 5000+ processor for socket 939 and claims that it has 2600MHz core-clock and 2MB of cache (1MB per core) – exactly the same specifications as compared to AMD Athlon 64 FX-60. On the other of the same document the chip is described as 2600MHz processor with 1MB of cache (512KB per core).

So far the correct specification is unclear, but on the afternoon of Thursday the data regarding the mysterious AMD Athlon 64 X2 5000+ was still inside the document.
