- The reason for the success of the 386SX is in the fact that it is cheaper
- to build 16-bit MBs as compared to the cost and complexity of building a
- full 32-bit MB. As an example, a 33MHz 386sx MB costs around $100, while
- a 25MHz i486sx MB costs around $200(US). Another point to consider; MB
- designs require a minimum memory compliment to match the data width. With
- 16-bit designs, that's two SIMM sticks, which cost $60US. With 32-bit
- designs, that's four SIMMs, which cost $120US (both cases 1MB SIMMS at
- $30US each). With a 64-bit design, that would be eight SIMMs, which would
- be $240US for 8MB or nearly $1000US for 64MB (using 4MB SIMMs at around
- $125US each). So there are some real cost differences to consider between
- 32- and 64-bit designs.
