486 sx-16 CPU collectable?

[Rhonda85]

I seen in ebay where an intel 486 SX-16 sold for $67.50! This is the cpu only, nothing else. Were these rare or what?

 

[hooflung]

FACK... man I have a cpu collection from AM286 to Nx586 to K6... and every chip I could get in between and beyond. SX16s aren't rare.... go to a packard bell graveyard m8... they sold the petooie out of those more than any other manufacturer. Now... a Intel 80487SX math co for one... I'd even consider giving up some coin for that.

Sounds fake. I thought the slowest 486 was 33MHz.

Nope- and there were 20- and 25 Mhz versions too. Sssssmokin!

486DX or 486SX? You should study up on your CPUs!

The 486DX had 20MHz, 25MHz, 33MHz, and 40MHz (AMD) variations.

The 486SX had 16MHz, 20MHz, 25Mhz and 33MHz versions, sans the math coprocessor.

The 486DX2 had 50MHz, 66MHz, and 80MHz (AMD) variations.

There was also a 486DX4 100MHz processor.

You forgot a few, too

IBM made a 486DX/2-80, when Intel's fastest was 66MHz. It was called the 'Blue Lightning', I have one in my drawer

Also, AMD made a 486DX/4-120.

Ha! I was not aware IBM made their own version of the DX2-80. I totally forgot about the DX4-120! That CPU did not last too long with the Pentium I craze sweeping right around that time.

 

[Maximilian]

Yea, theres pentium PRO's on there for like $200+ and even an itanium I 733 for like $2291, some sellers just suck...

 

[MiranoPoncho]

lol i've got a chomper and dos 5.0 sealed. wonder how much i could make..

Some more chips around the same time:

AMD did make a 486DX4-133, very few were labelled as such, they were renamed and more often seen as Am5x86-133 and sometime had PR-75 description to show that it was supposed to be about as fast as a Pentium 75 (minus the Pentium instruction set). Keep in mind this was around the Windows 95 era.

Cyrix also made a Cx5x86 at 100, 120, and 133. Some of these could overclock very well. The Cyrix MediaGX (which integrated a whole lot onto the die) were based on the Cx5x86.

These were all descendents of the 486DX and could run on some of the nicer Socket-3 boards. Yeah Socket-3, which was around before a lot of people were born here i bet.

Cyrix made a 486 SLC and SLC2 which were NOT Socket-3 compatible chips. They were actually based on a 386SX core - kind of a dirty little secret. Because of this, it ran on a 16-bit bus and was limited to 16MB (yes really) of RAM total. It also had a whopping 1KB of L1 cache. TI's version had 8KB.

 

[ElFenix]

anyone remember cyrix's 6x86? you could fry an egg on those... friend of mine had like 4 of them for his small biz

Yeah, I had a Cyrix 120....think it was rated at P90 or so. Had a 5x86-133 too- if you had a good chip and a VL-bus mobo, you could run it at 40MHz FSB for 160MHz :shocked:

I seem to recall that Texas Instruments made 486SLC chips also.

 

[ChiPCGuy]

This thread is starting to bring back some old memories! I have been building PCs since 1989, so I have worked with most of the above and have also built TurboXTs and 80286 machines. I think most of us older hardware builders have literally forgotten more than most of the modern "techs" will ever know.

 

[Painman]

Intel also made a 486DX-50 - not a DX2, it had a 50 MHz frontside bus. They didn't enjoy much popularity, I believe because that bus speed was hard to handle for the rest of many systems.
