Intel i486 SX33

The 486SX33 was a nice CPU back in the day. Certainly not the fastest one but it provided decent performance for its price point. Especially since most software didn't need a co-processor (FPU) which the 486SX didn't have.

This particular CPU is basically a one-of-million 486SX built in 1993. However, if you look closely the Intel logo is printed at an angle. I don't recall seeing other CPU's that have such a big deviation in its printed logo. From the looks of it, it seems like a genuine Intel part. Since the SX25 would usually run at 33MHz some SX33 CPUs are counterfeit, reprinted SX25 models. Some of these 'fake' CPUs are hard to distinguish from the real product.
