The name "Pentium" is originally derived from the Greek word pente (πέντε), meaning "five", a reference to the prior numeric naming convention of Intel's 80x86 processors (8086–80486), with the Latin ending -ium since the processor would otherwise have …

The original Pentium-branded CPUs were expected to be named 586 or i586, to follow the naming convention of prior generations (286, i386, i486).

It is an advanced superscalar 32-bit microprocessor, introduced in the year 1993 that contains around 3.1 million transistors. It has a 64-bit data bus and a 32-bit address bus that offers 4 Gb of physical memory space. While the maximum clock rating offered is around 60 to 233 MHz.

Feb 3, 2023 · This processor is also called Pentium 1, P5 otherwise Intel 80586, because it was the 5th generation of Intel microprocessors. The Pentium 1 is the first microprocessor in the Pentium series.

Apr 15, 2019 · "i486" refers to Intel 80486 (because 80486 ends with 486). But why does "i586" refer to Pentium 1, and why does "i686" refer to Pentium Pro? In general, it doesn't. It's a linux convention. Intel switched to names for marketing because you can trademark a name but not a number. (Apparently according to a US court decision).

Aug 16, 2024 · It was supposed to be called the 80586, but the US court ruled that you cannot trademark a number. The Intel processors were available between speeds of 60 MHz and 300 MHz, had a 64-bit data bus , and had 1.9 million more transistors than the 80486DX (3.1 million).

Apr 4, 2016 · Nexgen created their own x86-compatible microprocessor, calling it the Nx586. At the time of the acquisition, Nexgen had already finished the design of their next-generation processor core -- the Nx686. AMD used the Nx686 core and created the successful K6 processor.

Wider internal datapaths: 128- and 256-bit wide. Added second execution pipeline. Superscalar performance allows two instructions per clock cycle. another 8 KB for instructions. Added branch prediction.

Dec 20, 2018 · The 80586 was Intel’s fifth generation CPU architecture, and the first to be given a name after they lost their case to trademark numbers. Our first family machine was a 486SX, but the first computer I built myself from parts as a teenager …

1992 Intel attempts to introduce the Intel 80586. Finding that it could not get a trademark on a number, Intel changed the name to “Pentium”. The name “80586” was used briefly as a generic name for the Pentium and its clones by manufacturers such as AMD.
