Intel unveiled the next generation of its Xeon processor, the company's first chip to include Extended Memory 64 Technology, which allows the processor to run both 32-bit and 64-bit software. A number of hardware vendors, including Dell and Hewlett-Packard, have thrown their weight behind the chip by detailing plans to support it in forthcoming servers and workstations. Intel in July 2004 also released a chip set for workstations based on the Xeon processor. The E7525 includes a faster 800 megahertz system bus, DDR2 memory, and Intel's next-generation PCI Express interconnect. The Xeon, which had been codenamed Nocona, comes more than a year after Intel rival Advanced Micro Devices issued its Opteron processor. Extending Intel's 32-bit x86 processor instructions so they can handle 64-bit computing, Xeon's approach is similar to Opteron's. Although Opteron and Nocona are expected to run the same software, they have significant differences. Intel have taken a different approach to how they balance the system overall. Intel chose to go with a faster front-side bus, faster subsystem and PCI Express. Nocona and Opteron systems will have different designs and use different chip sets, but for most users, the difference between the two processors will not be visible.
