Regardless whether DX or SX.With cache an sx40 would give an early ISA only 386dx-33 a run for it’s money
Heck IBMs 386SLC seemed to run circles around identically clocked 386DXs but it may have also coincided with the IBM having local bus IDE and VGA VRS ISA all around on the DX.
I have one with cache and no, it doesn't really. A DX25 or thereabouts is my experience.

It'll be around the equivilent of a Harris 286/2o in that regard. That is one reason my first x86 system was a 286/16 instead of a 386SX16. I had done my research being to computers in general..😉 Folk go on about 32-bit instructions and Windows 3.x 386enhansed mode. The reality is Win3.1 is quicker in Standard mode.
So if anyone on vogons is a 286 basher and a 368SX fanboi at the same clock speed go and do some research before posting inaccurate information...😉 A 286 will steamroller a 386SX of the same clock speed processing 16-bit instructions.
Let's talk when you find a 40MHz 286.
