-
- The fast RS6000s that exist now are multichip designs, which wouldn't
- work well for a mass-market system. However, the architecture had lots
- of promise for redesign (thus creating PowerPC) to allow for fast
- single-chip designs.
-
- At the time of the alliance, the Alpha was either not announced or had
- been just announced. It probably was never in the running.
- Politically, it would probably be impossible for Apple to base its
- next hardware generation on Intel processors. The R4000 is a nice
- chip, but at the time there were grave doubts about MIPS' survival. In
- addition, MIPS (even now) has nowhere near the resources to pour into
- chip design that IBM does. The Sparc might have been a decent
- alternative, but in mid-1991 the Sparc was mired in uncertainty. Even
- now, the Sparc line is pretty sluggish comparatively. Finally, HP's
- Precision Architecture line might have been interesting -- it's fast,
- it exists now, and it sells pretty well. The decision to go with IBM
- rather than HP certainly had marketing/political considerations;
- technically, they're both not too bad.
-
- As for Motorola, the 680x0 line clearly has potential, but it's taking
- too long to mature. The 88xxx line is more interesting, but again
- there were grave doubts about Motorola's ability to scale the line
- fast enough to compete with other RISC processor lines.
-
- The real question is going to be: how fast can Apple/IBM/Motorola
- scale the PowerPC line compared to how fast Intel can scale the 80x86
- family (P5, P6)? The 601 should be about the same speed as the P5, but
- first shipping machines will be about a year later. However, there's
- hope of the 602/3 happening before the P6. The 620 should happen
- before the P7. The second and third generation PowerPC chips should be
- significantly faster than the respective Intel chips.
-
- I still have doubts about the Sparc family. SuperSparc and HyperSparc
- have pushed out the line, but it looks like superhuman engineering
- was required. How fast will newer processors appear? This is
- important given that the 601 should be faster than current Sparc
- processors (and significanly cheaper). Similarly, the R4000 is great,
- but when will we see an R500? Alpha is really hot (figuratively and
- literally -- the chips need lots of cooling), but the current silicon
- is hideously expensive (I've heard quantity pricing of >$1,000 per
- chip). Can you see Apple trying to enter the mass market with a chip
- costing that much? Again, the HP-PA is a contender, but you don't get
- the market push and interest (and funding) with HP that you do with IBM.
-
- The next few years in the CPU business are going to be interesting...
