Not just a battle between RISC and CISC, but between proliferating RISC designs.
You forgot CRISP/Hobbit, another Dave Ditzel design for AT&T Microelectronics, which was almost picked up by Apple for the Newton before they switched to ARM.
Internally, I think it was called P7 (not to be confused with a different P7 which was an x86 project).
I've seen documentation, but it was labelled INTEL confidential even long after it was cancelled.
Details will be posted someday, I'm sure.
Why is the 6502 not considered RISC? It has a small instruction set, and most of the time, instructions finish in 2, 3 or 4 cycles.
In several retrospectives of the development of ARM, I've heard Sophie Wilson give a nod to Berkely RISC.
Prior to Itanium, Intel was defining an Alpha-like 64bit RISC processor also.
It got cancelled when HP proposed the Itanium collaboration.
I got to use several Sun SPARC systems at Uni, and MIPS (R3000) systems from DEC and Sony, and later an R4400 from SGI. A lot of SGI machines used an i860 for the GPU, but I don't think that the cheap(er) one that I used did. I bought myself an ARM2 for home. The very first SPARC machines were quite brittle in their performance: they could be fast, but it wasn't hard to find code that was slower on them than the older 68030-based workstations. The later ones (guessing SPARCv7 or v8?) were properly well rounded and performed beautifully. The DEC and Sony MIPS boxes were really nice. The floating point units were excellent (for the time), and performance was reliable. Ultrix, SunOS, Sony NEWS were all Berkely 4.2 or 4.3 based, so there was a great deal of source-code compatibility, even if the executables weren't. This was before the days of shared libraries, so they were simpler times. I used some lovely X terminals that were based on the i960, but just like the i860 in the SGI systems, they were effectively sealed units: there was no way to actually code for them.
Interesting to read you say that the Motorola 88000 was "the fastest" when released: was it ever used in any product? I can't think of any. I don't know whether that was because it didn't work, or was just overtaken by the PowerPC collaboration?
What is the point of crediting the first RISC? It was just a revival of the simple load-store architectures of the 1950s and 1960s. Who gets credit for being the first to revive something? Usually - no one - but in this one case - Answer: professors at top ranked universities! Their job is to take credit and hype their shit even if it's not exactly innovative ...
