AMD Am486 DX40 '24361'

This is not the chip that people hoped it would be. AMD's 40MHz 386 ran very well and was quite fast for a 386 because the front-side-bus (FSB) did its job at 40MHz as well. The 486 model, however, was usually plugged into a normal motherboard with Vesa Local Bus (VLB) slots. These slots ran fine at... > Read more

AMD Am486 DX2/66 '24361'

AMD's version of the 486DX2/66. Runs practically the same as the Intel 486DX2/66. Usually the Intel part is a tiny bit faster but it's not noticeable in real life.... > Read more

AMD Am486 DX2/80 '25253'

AMD's 80MHz 486, nothing spectacular actually. However, Interesting to see is that Intel never made DX40 or DX2/80 486 processors. They always stuck to the more common front-side-bus (FSB) clock frequencies that were more reliable in the old days. At the time that the 486 was new it was difficult t... > Read more

AMD Am486 DX2/66 '25220'

I have three different AMD 486DX2/66 CPU's:
A80486DX2-66
An older 1994 DX2/66 without specific markings that indicate the amount and type of L1-cache.

A80486DX2-66NV8T
An 1995 model with NV8T marking. This is 8KB... > Read more

AMD Am486 DX2/66 '25398'

Just like this 486 but with write-back L1-cache rather than write-through. The SV8B marking on this CPU indicate it has the faster write-through cache. This CPU is also known as Enhanced Am486.... > Read more

AMD Am486 DX4/120 '25398'

One of the faster 486 processors. The 120MHz model is up to speed with it's 40MHz front side bus (FSB). Unfortunatly the 40MHz FSB is not always a big improvement over the 33MHz FSB. In my case the DX4/120 doesn't run Doom faster than a DX4/100 because the PCI bus is clocked lower when using the 40M... > Read more

AMD Am486 DX4/100 '25398'

Just like the other Am486 CPU's but with the 100MHz-barrier broken.

This model is also known as the Enhanced Am486DX4-S 100MHz because is has write-back L1-cache. CPU's with write-back cache are slightly faster than CPU's with write-through c... > Read more
