Here are some chips AMD is planning to make:
ClawHammer 940-pin – 1MB L2 cache, dual-channel memory controller, made at 0.13 micron SOI nodes.
ClawHammer 939-pin – 1MB L2 cache, dual-channel memory controller, Cool’n’Quiet technology, made at 0.13 micron SOI nodes.
Newcastle 939-pin – 512KB L2 cache, dual-channel memory controller, Cool’n’Quiet technology, made at 0.13 micron SOI nodes.
Winchester 939-pin – 512KB L2 cache, dual-channel memory controller, Cool’n’Quiet technology, made at 90nm SOI nodes.
San Diego 939-pin – 1MB L2 cache, dual-channel memory controller, Cool’n’Quiet technology, made at 90nm SOI nodes.
Note they all have dual channel memory controller, looks like AMD is catching up, starting with those current 64bit chips.
