Found this powerful Intel I486 (almost I5) processor in basement, can’t wait to try it with newest video games on ultra

Wow that looks so new! I have an Intel 10th Gen gaming PC (which is my best PC)
sekanna
Oooo 25mhz! Speeding along
AquaCobalt
That's the old Intel logo but I have a bunch of old laptops too.

I have one of those lying around somewhere. I also have a 4 bit processor I think.

Wow...i had those...and the SXII

I hate my Intel Inside pc

sx is a dx with it's floating point unit disbled (these failed fpu tests in production but were sold anyways) ... slow AF

Adding a software FPU actually worked

i486sx? Back in the day, the joke was that they left out the 'u' and it was really the 'i486sux'. The one you wanted was the 486DX.

I wonder how many kids got bullied over this

Weren't they faster than the Pentium because of a mathematic function error?

Apparently you were there, lol!

Yep, initially they were DXes with an added connection in the package which disabled the FPU. Cost Intel the exact same to produce but 1/
delpharseven
they needed something to compete with AMD on price without losing the fat profit margins they were making on the DXes. 2/2

I sold the SOFTWARE that was used to DESIGN chips like that. Daisy Systems, 1985. It understood connectivity, unlike prior
wadenelson1
CAD software that only drew lines and polygons. Ours would "rubber band" connections and enforce design rules.
wadenelson1
Without it there would never have been a Pentium chip. Too easy to make design errors. Nowadays the lines / transistors are SO small
wadenelson1
that managing the heat, crosstalk is the design challenge. NASA paid Texas Instruments to combine transistors into the first IC's (chips)
