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. [n] Usually 3 [o] Intel Pentium, AMD K5, Cyrix 6x86MX ...
This returns the processor's serial number. The processor serial number was introduced on Intel Pentium III, but due to privacy concerns, this feature is no longer implemented on later models (the PSN feature bit is always cleared). Transmeta's Efficeon and Crusoe processors also provide this feature. AMD CPUs however, do not implement this ...
Some Xeon Phi processors support four-way hyper-threading, effectively quadrupling the number of threads. [1] Before the Coffee Lake architecture, most Xeon and all desktop and mobile Core i3 and i7 supported hyper-threading while only dual-core mobile i5's supported it.
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.
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
x86 assembly language includes instructions for a stack-based floating-point unit (FPU). The FPU was an optional separate coprocessor for the 8086 through the 80386, it was an on-chip option for the 80486 series, and it is a standard feature in every Intel x86 CPU since the 80486, starting with the Pentium.
The presence of wide SIMD registers means that existing x86 processors can load or store up to 128 bits of memory data in a single instruction and also perform bitwise operations (although not integer arithmetic [n]) on full 128-bits quantities in parallel. Intel's Sandy Bridge processors added the Advanced Vector Extensions (AVX) instructions ...
A follow-on chip, the TMS 9980, was designed to compete with the Intel 8080, had the full TI 990 16-bit instruction set, used a plastic 40-pin package, moved data 8 bits at a time, but could only address 16 KB. A third chip, the TMS 9995, was a new design. The family later expanded to include the 99105 and 99110.
