From the retailer

Intel Core i5-12400F Alder Lake LGA 1700 18MB Smart Cache Processor 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) 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 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 AES New Instructions (Intel AES-NI) are a set of instructions that enable fast and secure data encryption and decryption. AES-NI are valuable for a wide range of cryptographic applications, for example: applications that perform bulk encryption/decryption, authentication, random number generation, and authenticated encryption. 12th gen Intel Core i5 Processor Generation Alder Lake Processor Codename 6 Processor Threads 4.4 GHz Processor Boost Frequency Smart Cache 65 W Processor Base Power Instruction Set An instruction set refers to the basic set of commands and instructions that a microprocessor understands and can carry out. The value shown represents which Intels instruction set this processor is compatible with. Intel Turbo Boost Technology Intel Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it, and increased energy efficiency when you dont.
