The latest badge promoting the Intel Core branding. The following is a list of Intel Core processors.This includes Intel's original Core (Solo/Duo) mobile series based on the Enhanced Pentium M microarchitecture, as well as its Core 2- (Solo/Duo/Quad/Extreme), Core i3-, Core i5-, Core i7-, Core i9-, Core M- (m3/m5/m7/m9), Core 3-, Core 5-, and Core 7- Core 9-, branded processors.
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.
Copy an 8, 16, 32 or 64-bit integer register or memory operand to all elements of a XMM or YMM vector register. VBROADCASTI128: Copy a 128-bit memory operand to all elements of a YMM vector register. VINSERTI128: Replaces either the lower half or the upper half of a 256-bit YMM register with the value of a 128-bit source operand.
AMD64 (also variously referred to by AMD in their literature and documentation as “AMD 64-bit Technology” and “AMD x86-64 Architecture”) was created as an alternative to the radically different IA-64 architecture designed by Intel and Hewlett-Packard, which was backward-incompatible with IA-32, the 32-bit version of the x86 architecture.
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly.
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU.. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.
In each generation, the highest-performing Core i7 processors use the same socket and QPI-based architecture as the medium-end Xeon processors of that generation, while lower-performing Core i7 processors use the same socket and PCIe/DMI/FDI architecture as the Core i5. "Core i7" is a successor to the Intel Core 2 brand.
The introduction of protected mode to the x86 architecture with the Intel 80286 processor brought the concepts of physical memory and virtual memory to mainstream architectures. When processes use virtual addresses and an instruction requests access to memory, the processor translates the virtual address to a physical address using a page table ...
