The AMD dual-core Opteron 100 series will likely use Socket 939, according to sources at motherboard makers.
It is said that the Opteron 152 will be AMD's last Opteron 100 series Socket 940 processor. All new dual-core Opteron 100s will be Socket 939.
AMD’s move is aimed to promote dual-core Opteron processors in the entry-level server and workstation segments, the makers commented. The new 100 series Opterons will allow vendors to offer lower cost Opteron systems, as Socket 939 motherboards widely support unbuffered DIMMs instead of registered DIMMs, the makers indicated.
Socket 939 motherboards are also cheaper because they are built on four-layer PCB instead of six layers. The dual-core Opteron 100 series is expected in the third quarter of this year.
