Processor used in older PC's. First x86-CPU with 32bit
Existed at frequencies up to 40 MhZ
There are 2 Versions, 386SX and 386DX
The SX came from the word Sixteen, because this CPU had a narrower Data bus to reduce costs. It was developed as a 286 killer but is a slow piece of junk...
Comes from Intel...
Means reduced form of the CPU, originated from the 386 SX with its SiXteen bit databus.
Intel had the following SX-Types:
386SX: 386 with reduced Databus width
486SX: FULL DX with deactivated Coprocessor!
Amd usually took Intels designs and upgraded them so that they ran faster( eg 386@40, 486@40, 486DX2@80,....)
First 100% own development was the K5 which was a pentium killer, but not too successful.
AM is their short they write onto chips...
