Depends... The FX-60 has more cache than the 3800+, the 4200+ and the 4400+ (which only have 512KB per core) but has the SAME as the 4400+ and the 4800+ (these have 1MB per core). The FX USED to have more cache than regular socket 939 A64s before the A64 4000+ was released with 1MB of cache. Then the 3700+ was released and things got even messier.
