Intel i486 DX2/66

The DX2/66 was a popular processor in the 486 era. It has enough oomph to run Windows 3.1 and DOS games from that era. For instance, Doom runs a lot smoother on a system with a DX2/66 fitted instead of a DX33, especially when you're running a VESA Local Bus (VLB) graphics card.

This particular 486DX2/66 is less common because it has a nice blue heatsink attached. Most DX2/66 CPUs didn't have a heatsink mounted by Intel but a third-party heatsink or heatsink/fan solution. The heatsink is very similar to the Overdrive version except that it is ever so slightly taller. I never had cooling issues with both the blue and black (Overdrive) CPUs, however, that changed in summer of 2026 when I re-did my 486-benchmarks. This blue DX2 crashes after running a series of benchmarks. Adding a small fan solved the problem.

There are two major versions of the DX2. The P24 and P24D, of which the latter has a faster L1 cache mode called write-back that improves performance. The P24 version only offers write-through cache, which is slower. The 'SX731' (this model) is the P24 version. See this 486DX2/66, which is a P24D.

I have benchmarked this CPU in a fairly modern UMC PCI-based motherboard that allows me to incorporate benchmarks of other brands and faster types of CPUs as well. The Intel DX2/66 is generally compatible with every 486 motherboard out there, whereas the DX4 or Cyrix counterparts often need a more recent motherboard. Some of the benchmarks may appear wrong; a DX4/120 performing slower than a DX4/100 in Doom, but this is because the PCI bus runs slower on the 120MHz version due to the divider on the 40MHz PCI bus.

In the benchmarks, you see that with Doom, the DX2/66 is about 86% faster than the DX33, so the DX2 is not twice as fast, but it really does make a big difference.

Just like other 486-class CPUs, the DX version has the built-in floating-point unit (FPU). In 1993, the FPU wasn't really necessary for most people unless you used CAD or big spreadsheets.

This CPU has been benchmarked on a Biostar MB-8433UUD-A with UM8881F PCI chipset. Click here for more information about this system.
