Dhrystone ratings are affected by the quality of the technology.
Intel486(tm) compiler technology has been improving (as has most other),
so it's normal to see this rise in Dhrystones even tho the chips
themselves may not have change.

According to a newspaper article, the compilers developed for "P5"
will deliver better Intel486 performance too. So you can expect
another evolution of all the numbers.

This is IMHO relatively legitamate : most applications are
in HLL, so they never really see the chip itself in any way :
they see the compiler's view of the chip.
