The Pentium III was the first x86 CPU to include a unique, retrievable, identification number, called Processor Serial Number (PSN). A Pentium III's PSN can be read by software [20] through the CPUID instruction if this feature has not been disabled through the BIOS.
28 million transistors; All models support: MMX, SSE The 'B' suffix denotes a 133 MHz FSB when the same speed was also available with a 100 MHz FSB. The 'E' suffix denotes a processor with support for Intel's Advanced Transfer Cache [1] in Intel documentation; in reality it indicates a Coppermine core when the same speed was available as either Katmai or Coppermine.
Microsoft's Xbox (Pentium III processor), through the Xbox Linux project; SGI Visual Workstation (Pentium II/III processor(s) with SGI chipset) PC-98NX (models from 1997 to 2000) FM Towns; Sun Microsystems Sun386i workstation (80386 and 80486) Support for 8086, 8088, 80186, 80188 and 80286 CPUs is under development (the ELKS fork) [5]
The first CPU to support SSE, the Pentium III, shared execution resources between SSE and the floating-point unit (FPU). [2] While a compiled application can interleave FPU and SSE instructions side-by-side, the Pentium III will not issue an FPU and an SSE instruction in the same clock cycle.
Pentium is a series of x86 architecture-compatible microprocessors produced by Intel from 1993 to 2023. The original Pentium was Intel's fifth generation processor, succeeding the i486; Pentium was Intel's flagship processor line for over a decade until the introduction of the Intel Core line in 2006.
This was chosen because the 11/780 was roughly equivalent in performance to an IBM System/370 model 158–3, which was commonly accepted in the computing industry as running at 1 MIPS. Many minicomputer performance claims were based on the Fortran version of the Whetstone benchmark , giving Millions of Whetstone Instructions Per Second (MWIPS).
The Intel 810 chipset was released by Intel in early 1999 with the code-name "Whitney" [1] as a platform for the P6-based Socket 370 CPU series, including the Pentium III and Celeron processors. Some motherboard designs include Slot 1 for older Intel CPUs or a combination of both Socket 370 and Slot 1. It targeted the low-cost segment of the ...
