Xeon Phi processors (from Knights Landing onwards) also featured the PREFETCHWT1 m8 instruction (opcode 0F 0D /2, prefetch into L2 cache with intent to write) − these were the only Intel CPUs to officially support this instruction, but it continues to be supported on some non-Intel processors (e.g. Zhaoxin YongFeng).
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.
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
Beware that older versions of the Intel app note 485 contain some misleading information, particularly with respect to identifying and counting cores in a multi-core processor; [86] errors from misinterpreting this information have even been incorporated in the Microsoft sample code for using CPUID, even for the 2013 edition of Visual Studio ...
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), Core 3-, Core 5-, and Core 7-branded processors.
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).
All models support uni-processor configurations only. Intel HD Graphics P4000 uses drivers that are optimized and certified for professional applications, similar to nVidia Quadro and AMD FirePro products.
