Jaguar Vs Cognac

The two projects, which aimed to bring RISC technology to the Macintosh, had totally different approaches and resources. Here are some of the main points which put them at the antipodes.

Jaguar had dozens of engineers from the start and was a very ambitious project.
Cognac, at least initially, had a much smaller team. Work started as a stopgap solution to bridge 68k and RISC, later evolved into a “plan B” and then became the only way forward for the Macintosh.

Since the 88k architecture wasn’t compatible with the 68k one, Jaguar engineers chose to start with a clean slate, even tough this meant that there would be the need to recompile all previous software for the Macintosh. This was similar to the IA-64 debacle of Intel’s Itanium , which was humiliated by AMD’s evolutionary way to add 64-bit computing capabilities to the existing x86 architecture.
The Cognac team was much more pragmatic. (more…)
