35 years Intel 80486

Hey folks!
Let´s celebrate today the 35th anniversary of a very special chip in the CPU world: The Intel 80486.
Intel announced its second generation 32-bit processor on 10th of April 1989 and the i486 platform had a huge impact on the personal computer industry.
Why and with which features? Well, let´s have a closer look…

In the area of the chip where you can read the contributor's initials, I can see "PG" (top of the 3rd column). My guess is that it stands for "Pat Gelsinger", who started working on this chip when he was 24 years old, and he was a lead architect on this project. He was 28 years old when the chip hit the market. Of course, Gelsinger is now the CEO of Intel (good luck with this...). Among the initials, there is also "JC", and it may have been John Crawford, also a lead architect, as he was for the 80386 and the P5 family.

Nice, really nice! 👍👍👍

This brings gr8 memories, however, DX2 ran at 66 Mhz which was not mentioned in the video, i had one in the past with 16 MB of RAM which was the real shit back then.

DX2-66, the best one! I made an own video 2 years ago… check it out!

very nice video, thank you for sharing

Sweet!🤣

Isn't the 486 the last to have in-order instruction processing ? That is, completely immune to all kinds of spectre and meltdown vulnerabilities, because it doesn't have any kind of out-of-order and speculative execution ?
Also, also, several years ago, some mad lad installed the latest version of Gentoo Linux on a 486. It was not fast, but it worked! Able to play mp3 music and download stuff safely from the internet. Not very practical though. It should still work with the now latest Linux too, but I'm not sure how it would perform. There was some performance (and memory space) improvements (and that memory space might actually be quite big for a 486) in a recent version, there's a chance it might actually run better than that 2019? I think it was, version.
Also... damn, twice the IPC of 386, now that's a big generational improvement that we'll probably never see again. Even if instead of generation, we use 4 years (the "distance" between 386 and 486). Though on the bright side, that means that current stuff is getting obsolete much much later.

If I recall correctly the first generation Pentiums were still in-order execution, they lacked any super scalar execution pipelines; the Pentium Pro (which was technically a different product and pin out) had those a year later, the Pentium II and III therefore did and the in the Pentium 4 the added instructions and even some prediction were present in the Prescott core.... That's from memory, I'm by no way an expert, just a jobbing amateur at the time in the late 90's :D
