- The cache is definitely the main source of the 486DLC's performance

- of Intel's RapidCAD chip which is basically a 486 without the cache
- and with a 386 pin out. While the RapidCAD offers roughly twice the
- floating point performance of the Intel 387DX, my benchmarks showed
- it to be at most 25% faster than the 80386. Typical performance gain
- for integer applications is more like 15% though. This definitely
-
- Hmmm.. a local salesperson told me last May that this RapidCAD would
- give up to 70 % more performance for both fp and int operations and
- that the average gain is much less than 50 %. These numbers are agaist
- a separate 386 & 387 system (with same clock). I have not tested it.

- maybe he just tried to sell me on over expencive 486 motherboard.......
