LGA775 will not bring 64-bit to desktop P4s yet - Intel
Intel has reaffirmed its pledge that it will not to offer a 64-bit x86 desktop processor for some time yet.
The company this week told Xbit Labs that the 775-pin version of the 90nm Pentium 4, aka 'Prescott', would not ship with EM64T enabled, contradicting earlier reports that it would be.
Intel's Enhanced Memory 64 Technology (EM64T) was officially announced last February at its Developer Forum. At the time, Bill Siu, general manager of Intel's Desktop Platforms Group, said that the chip giant would not ship a mainstream Pentium 4 with EM64T until Microsoft was ready to ship the next major version of Windows, codenamed 'Longhorn'.
