Dec 15, 2020 · The Am386 and Am486 were designed as clock-for-clock equivalents of the corresponding Intel CPUs, based on reverse-engineering and AMD’s previous second-source licenses — at least the Am386 even used the same micro-code as Intel’s 80386. The only speed advantages came from higher clock speeds (40MHz v. 33MHz) and, in some Am486 models ...

Jan 9, 2024 · As per the previous question, AMD was known for launching versions of the cloned chips that operated at higher clock-speeds than Intel's own. A good example is the Am386 DX-40 which operated at 40MHz, when the best Intel 386 processor operated at 33 MHz. Wikipedia (note, not a good source) notes that it also had lower power consumption.

Jun 3, 2016 · I confirmed this worked as expected, using Am386/DX-40 + Intel 387 co-processor. The trick with the Am386 is having separate clock for CPU/co-processor, as the former runs at 40 MHz and the latter at 33 MHz. The UMC-386 mainboard supports this configuration fine.

Sep 25, 2023 · In the '80s and '90s the Intel x86 and Motorola 68000 families were the two leading microcomputer architectures in the 16-bit/32-bit personal computer scene. The 68000s were even preferred by the p...

Jun 5, 2018 · The 68020 is an improvement over the 68000 because it includes new instructions, possibly better speeds and so on. The 68040 is an improvement over the 68020 again for the same reasons, as is the 6...

Feb 22, 2017 · At this point I can get it to beep twice, but due to the lack of information I'm not really sure what the code means. Maybe it's because the hard drive is missing? I do have a bootable floppy in the drive and the floppy briefly reads it during the POST it seems. If it's any help the processor is an AM386.
