Intel Hyper-Threading Technology Intel Hyper-Threading Technology (Intel HT Technology) allows for two processing threads per physical core, increasing the efficiency of highly threaded applications and completing tasks faster. Intel Virtualization Technology for Directed I/O (VT-d) Intel Virtualization Technology for Directed I/O (VT-d) builds upon existing virtualization support for IA-32 (VT-x) and Itanium processors (VT-i) by adding new support for I/O-device virtualization. This technology enhances system security and reliability, as well as improves performance of I/O devices in virtualized environments. Intel TSX-NI Intel Transactional Synchronization Extensions New Instructions (Intel TSX-NI) are a set of instructions designed to improve multi-threaded performance scaling. By providing better control of locks in software, this technology makes parallel operations more efficient. Intel 64 Intel 64 architecture enables 64-bit computing on server, workstation, desktop, and mobile platforms when combined with supporting software. This architecture allows systems to address more than 4 GB of both virtual and physical memory, resulting in improved performance.
