Same socket

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.

I have only come across one of these units in the flesh, which I found on eBay in Australia a few years back. As these CPU's were only sold as OEM units and a very limited run of retail production they are rare as hens teeth nowdays. I have just decommissioned this CPU from my aging Socket 939 platform desktop PC and will be putting it up on eBay once again, and it will be interesting to see what price it fetches.
