In all the documentation and advertising I have found, nowhere is it clear whether the A8-3870K processor that I would like to buy and use is a 32bit or 64bit processor. It has to be 64bit for me to use it because I am currently using the A6-3500 processor and all 64bit operating systems (Win7, Win10, Linux -- separate hard drives). I have the FM1 socket, and the fastest, most similar processor I can find is the A8-3870K, but in the one place the architecture was mentioned, it said x86. The context was not such as to clearly mean 32bit or 64bit, only the general type of processor.
Furthermore, this won't be the only time I may have this problem, so if anyone knows of a processor architecture database, I would greatly appreciate a reference to that.
