The AMD Athlon XP brand is dead in the water, according to AMD's new processor roadmap, as the company migrates all of its CPU production to 90nm silicon-on-insulator (SOI) processes in early 2005, says DigiTimes. The report is based on its sources at Taiwan motherboard makers.

According to the report, AMD is all geared up to release its next-generation processors in the first half of next year. They'll be based on the 90nm Palermo core and code-named Sempron - both desktop and mobile versions will be produced.

The chip company will also boost output of its Athlon 64 processors to 65 per cent of its total CPU production in the second quarter of 2005, with the proportion of 939-pin chips higher than the 754-pin parts, the sources said, citing the AMD roadmap.

AMD will also unveil its dual-core server chips, codenamed Egypt, Italy and Denmark, in the second half of 2005 as planned, matching Intel’s roadmap for dual-core CPUs. A desktop dual-core chip, codenamed Toledo, will launch at the same time. Meanwhile, OEMs of mobile hardware will benefit from Albany and Roma - the latter to be a low-voltage processor. Following the codenaming logic? We aren't.

However, existing 64-bit Opteron and Athlon MP processors, both using 130nm technology, continue to soldier on until the second half of 2005, according to the roadmap.

Intel in contrast is already churning out 90nm-geometry processors, the flagship of which is the 64-bit Xeon, once codenamed Nocona.
