E-0 Step LGA775 CPUs Info & Pricing

By on July 7, 2004 9:07 pm

Intel plans to incorporate Execute Disable Bit (NX Bit) security technology
into Prescott-based Pentium 4 and Celeron D CPUs in Q3 this year. Only
LGA775-pin processors with E-0 stepping will initially have NX Bit support. The
letter “J” will be used after model numbers to distinguish chips incorporating
the new technology. Pentium M and Celeron M chips with NX Bit-support are
expected in the first quarter of 2005.
