I would like to ask how can you recognize a socket 939 CPU from the AM2 equivalent

+1 pin

Also considering the really high prices how much faster is the Fx-60 CPU

It isn't. Just swag.

Do i need to count each pins if i find a cpu? 😀

Perfect, that's it. So basically two angles has 90-degrees pins on the 939. 😀

The FX and Opteron have 1MB L2 per core. The Regular Athlon 64 and X2 CPUs only have 512KB L2 per core.

FX also has unlocked multiplier although that isn't really needed unless you have a board that is really bad at overclocking.

Some Athlon 64 for socket 939 does have 1MB cache per core like the 3700+, 4000+, X2 4400+ and X2 4800+ (some came in verions with both 1MB and 512kB cache but with different clock speeds).

This got me curious. Is there any speed difference between Opteron 185 and FX-60 or are they basically the same CPU? They seem to have same TDP too.

Same CPU except that the default stock voltage for the Opteron 185 is lower than the FX-60.

The Opterons were also supposedly binned better and overclocked better than there Athlon 64 counterparts, but it was sort of a toss-up.

My Opteron 175 I bought new was/is not that good of an overclocker.

If you want to get brave, you can de-lid the CPU and will get a 15-20C drop in load temps.

The Regular Athlon 64 and X2 CPUs only have 512KB L2 per core.

Regular Athlon CPUs had both options.
