Intel CPU Code Names 1971 - 2024

Go End

Prior to 1970, there was no standard "byte" size or configuration. The word byte, apparently first defined in 1956 at IBM as a "6-bit alpha-numeric character", varied between manufacturers and their machines. Memory was accessed via its "word address" with 36 bit words being fairly common. But magnetic tapes and disks measured their capacity in bytes.

In 1964 IBM redefined the byte as 8 bits with their proprietary, universal EBCDIC codesets with multibyte sequences for Japanese characters. Still in use on IBM's 10,000 or so mainframes nearly 60 years later.

In contrast to EBCDIC, between 1963-1968 the US American Standards Association defined 7-bit ASCII as a 7-bit character that included control codes, punctuation marks, single digits, the upper case and the lower case alphabet. It became the TTY (teletype) standard in telecommunications throughout the US, and worldwide, in particular via the US Army.
It was employed by Dennis Ritchie in 1971 at AT&T Bell to encode C, the software language that became the basis of C++, Java, Javascript, the Unix and Linux operating systems, Email, HTML, Google, and the Internet.

Also in 1971 Intel built the world's first commercially produced microprocessor based on the tiny integrated circuit first seen in 1958-1959.

In 1975, Byte magazine was launched. The word had arrived.

Are code names today even important?

Extract from May 2020 ...

We spoke with both official current Intel Senior Strategic Planner Jeff Tripp, who gave us the official company line, and former Principal Engineer Francois Piednoel, who provided an inside scoop.

Both Piednoel and Tripp agreed that Intel code names shouldn't matter as much to the public as they do. The official name, both told us, should take precedence. But Piednoel was the only one to go into why he thinks it doesn't.

"It's proving something that people are getting attached more to the code names than the brand of Intel processors. It's that the branding is terrible," he said.

Since introducing its Core line of processors in 2006, Intel's main line of consumer end CPUs have maintained that same naming scheme for more than a decade, simply updating the generation number on the box. For example, the company officially branded 2018's Coffee Lake line of processors as "9th Generation Intel Core" processors, while it called this year's (2019) Comet Lake line of processors "10th Generation Intel Core" processors. It's to the point, but according to Piednoel, it's not descriptive enough to be useful to customers, so they don't.

"It's like in the movie 'Airplane' where there is a poster for Rocky 23 or 24. We're getting there, right," he told us. "Like, we're the 10th generation Core i7. In 10 years, we're going to be at 21," he posited.

More seriously, he said "Maybe people don't understand this, but the biggest competitor for Intel is a four years old PC from Intel," with the idea that simply updating the generation number on a product gives the impression that it is simply a slightly improved version of a last-gen processor, rather than a unique piece of hardware with specialized abilities of its own.
