The CJE Micro's 5x86 PC CPU card sports an AMD 5x86 processor with 512KB Level 2 cache running at 133MHz. The card is actually a standard Acorn part but has been upgraded from a 486 processor to the AMD 5x86 by CJE Micro's.
The AMD 5x86 is actually a 486 processor that has had its clock quadrupled. As such it delivers roughly the performance of a Pentium 75MHz in a 486 form factor although a Pentium 75MHz will outperform a 5x86 processor for certain tasks.
