The report says AMD also intends to launch cheaper derivatives dubbed "Arcturus" and "Spica" in the fourth quarter of 2007. Arcturus will have two cores running at 2.1-2.3GHz and no L3 cache, while Spica will be a single-core chip aimed at the value segment.
Regarding socket compatibility, Altair FX will reportedly slip into Socket F+, while Altair, Antares, Arcturus, and Spica will be intended for Socket AM2+. The chips will be compatible with current Socket F and Socket AM2 motherboards, the report says, but Socket F+ and Socket AM2+ motherboards will also be available with support for the new HyperTransport 3.0 interconnect.
Oddly, HKEPC makes no mention of the "Barcelona" code name AMD officially told HardOCP was the correct name for its next-gen quad-core architecture. The Inquirer also recently said it had received word from inside AMD that Barcelona would launch in the second quarter of 2007, and that it would be followed by "Budapest" desktop processors with HT3.0 support in the fourth quarter of 2007.
