Hello, I found in the "configure" file of MPlayer the following note, about the k6 model 13: # TODO: how to determine if model 13 is a k6-2 or a k6-3? Couldn't find anything on amd.com The k6 model 13 are the k6-2+ and k6-3+. There is no difference between the two CPU, except that the 2+ has 128KB L2 cache instead of 256KB of the 3+.
