What type of Central Processing Chip (CPU) would a modern high-end server typically use?

A modern high-end server typically uses a 64-bit EM64T chip, primarily because these processors can handle larger amounts of memory and provide better performance for data-intensive tasks. The 64-bit architecture allows for addressing significantly more RAM compared to 32-bit processors, which makes it ideal for high-demand environments like servers that run multiple applications and handle substantial workloads simultaneously.

64-bit EM64T (Extended Memory 64 Technology) chips, a variant developed by Intel, support advanced features such as enhanced multitasking capabilities and improved performance in virtualized environments, both of which are vital for server operations. This architecture also ensures greater compatibility with modern operating systems and software that are designed to leverage 64-bit processing.

In contrast, 32-bit processors have limitations in memory addressing and are increasingly outdated for server use, as the demand for higher memory capacity continues to grow. An ARM chip, while increasingly popular in mobile devices and certain types of servers, is not typically the standard for high-end server CPUs where x86 architecture (which includes EM64T) dominates due to its performance characteristics and software compatibility.
