The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2] Many or most Xeons subsequent to this support VT-d.
Intel's "Virtualization Technology for Directed I/O" (VT-d), [44] included in most high-end (but not all) newer Intel processors since the Core 2 architecture. [ 45 ] In addition to the CPU support, both motherboard chipset and system firmware ( BIOS or UEFI ) need to fully support the IOMMU I/O virtualization functionality for it to be usable.
Intel's implementation of SLAT, known as Extended Page Table (EPT), was introduced in the Nehalem microarchitecture found in certain Core i7, Core i5, and Core i3 processors. ARM's virtualization extensions support SLAT, known as Stage-2 page-tables provided by a Stage-2 MMU. The guest uses the Stage-1 MMU.
Elkhart Lake: embedded processors targeted at IoT, released in Q1 2021. Gracemont Intel 7 process [19] Atom microarchitecture iteration after Tremont. First Atom class core with AVX and AVX2 support. Alder Lake: hybrid processor, succeeds Rocket Lake and Tiger Lake, released on November 4, 2021. Gracemont is used in E-cores of Alder Lake ...
Intel AMT is the set of management and security features built into vPro PCs that makes it easier for a sys-admin to monitor, maintain, secure, and service PCs. [11] Intel AMT (the management technology) is sometimes mistaken for being the same as Intel vPro (the PC "platform"), because AMT is one of the most visible technologies of an Intel vPro-based PC.
Intel Core 2 is a processor family encompassing a range of Intel's mainstream 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single- die , whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module . [ 2 ]
APICv is Intel's brand name for hardware virtualization support aimed at reducing interrupt overhead in guests. APICv was introduced in the Ivy Bridge-EP processor series, which is sold as Xeon E5-26xx v2 (launched in late 2013) and as Xeon E5-46xx v2 (launched in early 2014).
Intel's CPUs have varied widely in power consumption according to clock rate, architecture, and semiconductor process, shown in the CPU power dissipation tables. Like the last NetBurst CPUs, Core based processors feature multiple cores and hardware virtualization support (marketed as Intel VT-x), and Intel 64 and SSSE3.
