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.
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
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.
In early processors, the TSC was a cycle counter, incrementing by 1 for each clock cycle (which could cause its rate to vary on processors that could change clock speed at runtime) – in later processors, it increments at a fixed rate that doesn't necessarily match the CPU clock speed.

An iterative refresh of Raptor Lake-S desktop processors, called the 14th generation of Intel Core, was launched on October 17, 2023. [1] [2]CPUs in bold below feature ECC memory support only when paired with a motherboard based on the W680 chipset according to each respective Intel Ark product page.
All models except C2x38 support Intel QuickAssist Technology (cryptography accelerator) SoC peripherals include 4 × USB 2.0, 4-6 × SATA (1 for C2308, 2 for C2316, C2508, C2516), 4 × Integrated GbE LAN (2 for C2316), 2 × UART, and 8-16 lanes of PCI Express 2.0 (4 lanes for C2308), in x16, x8, x4, x2, and x1 configurations. Package size: 34 ...
Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
The latest standard badge design used by Intel to promote the Celeron brand. The Celeron was a family of microprocessors from Intel targeted at the low-end consumer market. CPUs in the Celeron brand have used designs from sixth- to eighth-generation CPU microarchitectures. It was replaced by the Intel Processor brand in 2023.
