Advanced Micro Devices has added products made using 90nm fabrication process into the shipping range of desktop AMD Athlon 64 microprocessors without making loud hype regarding the matter.

According to AMD’s web-site, the company’s lineup of 64-bit desktop processors include chips that are made using 90nm Silicon-on-Insulator process technology. Currently the company lists there microprocessors rated at 3800+, 3700+ 3500+, 3400+, 3200+ and 3000+ for Socket 754 and Socket 754 infrastructure. Such chips function from 1.80GHz to 2.40GHz clock-speeds.

A recently unveiled roadmap of the Sunnyvale, California-based chipmaker indicated plans to release a number of AMD Opteron processors code-named Athens, Troy and Venus, a Mobile Athlon 64 processor known as Oakville and a desktop Athlon 64 processor code-named Winchester produced using 90nm fabrication process in the second half of the year. The initial commercial shipments of AMD64 chips produced at 90nm nodes were officially said to commence in the third quarter of 2004.

AMD officially announced it had begun shipments of 90nm mobile products to customers, but did not reveal when it planned to supply 90nm desktop SKUs.

Earlier this year a report at a web-site claimed the new AMD Athlon 64 3500+ processors made using 90nm fabrication process had scored about 5% faster than the same 3500+ chips produced using 130nm process technology in CPUMark99 benchmark. The benchmark measures CPU integer unit and data processing speeds. Another benchmark the web-site had posted, SiSoft’s Sandra, showcased that the forthcoming AMD64 chips are approximately as fast as the current offerings.

AMD did not comment on the story.
