Intel NG80386SX -20
The 'Magix' motherboard on which this 386SX20 is fitted can run with 0 wait-state (0WS) memory and gets incredibly high memory bandwidth. Both the chipset and the 0WS form the base for this kind of performance.
For a 386SX20 it's a fine system to deal with, however, in the benchmarks another 386SX20 is included that scores better in all applications except memory bandwidth. The reason is simple; the other SX20 runs with 16KB on-board cache! Cache increases all-round performance and was quite expensive back in the day. It's unusual for a low-clocked 386SX to have cache at all so the performance figures for the 386SX with cache are uncommon.
