Intel i486 DX33

A regular 486DX33. Although not many people used the 'DX' part (which indicates it has an on-board co-processor) a lot of people thought that the 'DX' was faster. They would've been right if it was a 386 because the SX/DX suffix has a different meaning with 386's. With 386 class processors SX means a 16-bit external databus and DX a 32-bit.

Years ago I used to run a DX33 in which I later fitted a Cirrus Logic VLB video card. I think that the SX33/DX33 with VLB is the slowest combination that run's Doom fairly well. Of course the bigger levels in Doom II can bring down the FPS (frames per second) but the three episodes of the original Doom ran playable, especially back then. In hindsight I would recommend a DX2/66 because Doom runs a lot better on that CPU but if you don't know better the DX33 is fair enough .

A similar processor has been benchmarked! Click here to see this processor and the benchmarks.
