- 1 MB L2 (only)
- 128-bit based memory bus (dual channel)
- requires registered memory modules
- Opteron has provision for MP configuration, via coherent HT links
...
Opteron is included in the context of socket 940 and A64 FX.
An Opteron is basically an A64 FX (1 MB L2, dual channel memory controller w/ 128-bit memory bus) with the same internal core (SledgeHammer) with a few extra capabilities such as the coherent HT links used for connecting to other processors via HT bus for building multi-processor system.
