The first 64 bit Pentium 4 is to be sold on the first of August, for a price of $278. The 64 bit Pentium 4 product line will include a 3.20GHz, 3.40GHz and 3.60GHz processor respectively priced at $278, $417 and $637. Later a $673 costing 3.80GHz model will be launched. Processors without 64-bit technology will be sold at an equal price.
The 64-bit Pentium 4's will work with i925X and i925XE chipsets and are aimed at server and workstation markets.
Earlier this year Intel unveiled its Extended Memory 64 Technology also known under 64-bit Extension Technology or IA32e that let Intel’s Prescott, Nocona and Potomac processors to execute specially-written 64-bit code while maintaining absolute compatibility with today’s 32-bit applications. Nocona is code-name for Intel’s upcoming Xeon processors for 2-way servers and workstations launching in Q2 2004; Potomac is the name of the core that enables next-generation Xeon MP chips unveiling in the Q1 2005; Prescott is the core that powers current Pentium 4 E processors and will power special chips for uni-processor servers and workstations with 64-bit capability. Previously it was believed that all Prescott processors in LGA775 packaging, such as Intel Pentium 4 E, would sport EM64T, but Intel denied such claim.Source: X-bit labs
Intel said it would ship Prescott processors with 64-bit capability for 1P applications only to system integrators requesting such microprocessors for their servers and workstations. Although all Prescott CPUs, including Intel Pentium 4 and Celeron, are 64-bit from micro-architectural standpoint, processors supplying for retail channels as well as for typical desktops will have their 64-bit capability disabled. However, some sources doubt that it will be absolutely impossible for end-users and hardware enthusiasts to get Intel’s 64-bit Pentium 4 chips. They suggest that there will be some of such microprocessors supplied as OEM parts and reaching the channel.
