It enables an environment where applications can run within their own space, protected from all other software on the system. Intel Virtualization Technology for Directed I/O (VT-d) Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments. Intel Virtualization Technology (VT-x) Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple virtual platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions. Intel 64 Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software.¹ Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory. Intel Clear Video HD Technology Intel Clear Video HD Technology, like its predecessor, Intel Clear Video Technology, is a suite of image decode and processing technologies built into the integrated processor graphics that improve video playback, delivering cleaner, sharper images, more natural, accurate, and vivid colors, and a clear and stable video picture. Intel Clear Video HD Technology adds video quality enhancements for richer color and more realistic skin tones. Cache CPU Cache is an area of fast memory located on the processor. Intel Smart Cache refers to the architecture that allows all cores to dynamically share access to the last level cache.
