In this Video I am showing the slowest 486 which was ever produced. The Intel 486SX at 16 MHz. We will do some intesive benchmarks on a propper board of its time, an early 486 board with just ISA bus. The second chip which will get tested and benchmark is the Kingston Turbochip which is an upgrade chip and contains an AMD 5x86 at 133 MHz and will give our old board an exreme boost like from 0 to Hero :-) The usual benchmark programms as speedsys, norton sysinfo and checkit as well as some games are completing here our results.
