What is EM64T Xeon?

EM64T is a feature in the company’s upcoming uni- and dual-processor Xeon offerings for the server and workstation market that allows the devices to work in both 32- and 64-bit modes. Server manufacturers Dell, Hewlett-Packard, IBM, and Unisys have revealed plans to offer systems based on the new Xeons.

What is EM64T support?

Intel Extended Memory 64 Technology (EM64T) enables 64-bit computing on the server, workstation and desktop platforms when combined with supporting software. Intel EM64T provides support for: 64-bit flat virtual address space. 64-bit pointers. 64-bit wide general purpose registers.

What is EM64T architecture?

EMT64T was Intel’s implementation of AMD’s AMD64 architecture. It is essentially a straight-forward copy of AMD’s strategy of making 64-bit extensions to the 486 architecture. The creation of EM64T has as much to do with company politics as it does to do with technology.

What is EM64T CPU?

Intel Extended Memory 64 Technology (EM64T) enables 64-bit computing on the server, workstation and desktop platforms when combined with supporting software. Intel EM64T improves performance by allowing the system to address more than 4 GBof both virtual and physical memory.

What is AMD64 or EM64T architecture?

AMD64 supports 3DNow! EM64T lacks some model-specific registers that are considered architectural to AMD64. These include SYSCFG, TOP_MEM, and TOP_MEM2. EM64T supports microcode update as in 32-bit mode, whereas AMD64 processors use a different microcode update format and control MSRs.

Is the Intel EM64T 32 bit or 64 bit?
