CPU Information
AMD Opteron 156 is the fastest single-core processor for socket 939. Clocked internally at 3 GHz, the OSA156DAA5BN is 600 MHz, or 20% faster than the fastest single-core socket 939 Athlon 64 CPU, and 400 MHz (15%) faster than dual-core
Athlon 64 FX FX-60 or
Opteron 185. This makes it a perfect, albeit expensive, upgrade for old socket 939 motherboards when the best single-core performance is required. When upgrading a general purpose motherboard always make sure that the motherboard supports this Opteron processor.
