Intel at 65-nm in 2005?
Intel announced that they are targeting 65-nm chips in 2005 with SRAM samples at this time. ZDNet provides a good overview of the advantages and challenges in reducing chip size. In short, a smaller chip "improves performance, reduces costs and can potentially cut energy consumption."
Current chips, including the PowerPC 970, have been produced at 130-nm, but both Intel and IBM are ramping up 90-nm chip production at this time. 90nm PowerPC chip technology will be presented in February 2004 by IBM and will presumably make their way into future Macintoshes.
As previously reported IBM also plans on introducing 65-nm chips in 2005 using their SSOI (Strained Silicon on Insulator) technology.
