- Still, Intel drives volumes high enough that while their chips may not be
- the fastest per transistor, they are often the fastest per dollar. Economy
- of Scale is very important here. (Hence the reason NeXT didn't go with the
- 88k.) Next is not in the super fast workstation market -- they are in the
- desktop market. They need a processor base that has a reasonable tradeoff
- between speed and price. Motorola cannot not even keep up with Intel in terms
- of chip speeds and Intel lags the Riscs by about a year.
-
- Next could adopt a "low volume" high performance Risc architecture, but they
- would have to abandon the low end of the market. The Pentium will sell well and
- run far faster than the current 68040 based machines. It will be out probably
- a year before the 68060 and Next has already done a significant amount of
- porting work to the family. The 80486 is already out and running at higher
- speeds than the 68040. The silicon is probably cheaper.
-
- The 80x86 dominates the applications markets. It will have a huge market for
- the next decade at least. There is too much development invested in it for it
- to go away overnight. If Next stays with Moto's 68K they will perform like a dog
- for the next year and a half. If they go to a Risc like the R4000 or the 88K
- they are commiting to paying premium prices for their processors and doing a port to
- an architecture that does not have an installed base to insure its survival.
- Their choices seem quite limited and the Intel line seems the best. It is ready
- soon, the work for a "complete" port has been going on for some time, it is
- going to be cheap and there will be a "next chip" in the family.
-
- Anyway,
