Athlon k7 with giant heat sink
This is an AMD Athlon K7 (Slot A connector), year of manufacture 1999. I've found it on a waste disposal site in Denmark while disposing of building rubble.
It's looking quite fascinating with that very big gold-colored heat sink. Unfortunately it doesn't fit in the mainboards that I own because it's not Slot 1 (Intel) but Slot A (AMD), which is just mirror inverted. That is, the heat sink had to be just on the other side of the CPU, then I could use it. It's quite more powerful than *all* of my CPUs I own (AMD k6, Pentium II, ...)
Now take a look at this composition with an Intel Pentium II Slot 1 CPU.
