AMD Zone has a nice article (http://www.amdzone.com/modules.php?op=modload&name=Sections&file=index&req=viewarticle&artid=63&page=1) on what happened when they got their hands on a 90nm Athlon 64 3000+. Plenty of benchmarking and even overclocking are discussed. The Athlon 64 3000+ 90nm comes with 512kb cache and runs at 1.8GHz.
