It’s a Pentium 3 from 1998. Back then CPUs were installed on cards like this and put onto a slot on the motherboard. This was done because the L2 cache on these chips took up so much space that they wouldn’t fit on a chip you would put into a socket on the motherboard. This didn’t last very long though, only the Pentium IIs, early Pentium IIIs and AMD’s equivalent (I think these were the K6 CPUs) used the slot design. The physical size of the cache decreased and Intel and AMD were able to go back to a regular chip design by the turn of the millenium.

I remember holding one of these (pentium2) in my hand. And if I am remembering right I was able to put tape over 2 or 3 of the pins and make my pentium 2 300 mhz run at 450 mhz.

I have a couple of these in the basement in a box, don’t know if i have a MB for them tho….

If Intel core 9 14900K is a human…..Op found a monkey.

I had a pentium II 400mhz chip just like this! Woo!

No offense, but the name is right there. Pentium III, Slot 1.
Slot 1 was an attempt to change CPU form factor from socket to slot, of course it failed, but Pentium IIs and Pentium IIIs were built on the form factor before it was abadoned.

Pentium 3 it legit says on the first image

A damaged one

A new damp one, judging by the water on those leaves 😛

Pentium !!!
Man why can modern processors be so excited about things.

A cardridge Cpu just like old Nintendo games. Funny old times.

Oh man, this was made in the Philippines. I remember when there used to be a huge Intel factory here.

It says right on the case.
Since when has this sub become the go-to place for people too stupid to not know how to use Google?

Glad we didnt standardize this form factor

Geeze I wonder what it could be., If you ever find out let me know please.

Ohh, Slot 1 CPU. Nostalgia 🙂

I think it’s an old sempron, lol!

But in reality, that’s a very similar CPU to the one in the original Xbox. Good score
Oh it’s incredible to see this! I had a Celeron version of this, because although they were lightweight with less cache, they were supposedly easier to overclock, sometimes enough to offset the performance hit of the smaller cache. Back when I wanted to tweak more than I wanted things to work, and didn’t have the money to get good stuff anyway. 😅

Awwww man, this CPU has so many memories for me, it’s one of the first cpus i built into a machine myself. P3 Slot 1.
End of the 90s, being 18 years old, amazing movies getting released constantly, freedom. World was really looking up!

Why is nobody mentioning the fact its on a plant

I remember the Celeron 300a with fond memories.

Have one like this lying around, cool stuff!

thats a baby CPU being grown

It seems like the slot socket CPU
new8888888887
It is a pentium III The socket was strange but it is a normal CPU , before pentium 4 and I-series

These comments made me look up my first real PC’s CPU because I could’ve sworn it was a 866mhz Pentium 3 and I’ve never seen a slot CPU before – turns out that one was indeed just a regular chip. So not all Pentium 3s were slot CPUs.

Ok but why is it on a plant tho?
Looks like an AMD thing
