AMD Am486 DX40 '24361'
In the picture you see the 40MHz Am486 fitted onto an Octek motherboard. A fine combination for most people in late 1993 because it was affordable. Performance-wise it was fine although one could get faster systems like the DX2/66 or even the first Pentium's 
.
The Octek motherboard in question ... > Read more
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 Am486 at 40MHz was less successful. Ideally the 486 was plugged into a motherboard with Vesa Local Bus (VLB) slots. These slots were designed to run at 25MHz or 33MHz but cou... > Read more
A D-stepping of the original AMD Am486DX2/66 with package number 24361 made by Kyocera. The first models didn't have any additional numbers in it's model name. Later AMD made different versions which had write-back cache and a slightly modified chip due to a lawsuit with Intel.

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
An E6-stepping of the AMD Am486DX2/66 processor. It has package number 25220 made by Kyocera. This is the 'N' version of the CPU meaning that it doesn't have Intel ICE. See the description of this Am486 for more information about the different numbers.... > Read more
An Am486DX4/100 NV8T with an early 1995 date-code. I believe it's a fairly early Am486 100MHz part. Most of these CPU's are made after summer 1995. AMD did manufacture the Am486 for a long time: I also have a 16KB cache CPU from 2001.
This particular mode... > Read more
Identical to this Am486 except that this CPU is packaged in the Sumitomo-plant. Most Am486 CPU's are packaged by Kyocera. The symbol in the lower right corner indicates the plant.... > Read more
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
The normal/regular Am486 DX4/100 with write-through L2-cache. This version is slower than the SV8B marked Enhanced Am486.
I have another CPU like this that is 14 weeks older.... > Read more
An 1995 model with NV8T marking. This is 8KB write-through L1-cache. Should have identical performance to the CPU without additional markings.
See this Am486 for more information about the processor markings.... > Read more
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
Much like my other Am486 DX2/80 except that this one doesn't have the HEATSINK REQ'D marking.... > Read more
One of the faster true 486 processors available. The 120MHz model is up to speed with it's 40MHz front side bus (FSB). However, depending on your motherboard, the 40MHz FSB is not always a big improvement over the standard 33MHz FSB. In my case the DX4/120 doesn't run Doom faster than a DX4/100 beca... > Read more
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 ... > Read more
