Off topic here, but that's the current Natami board? It's tiny!
Yes, and the production board will not have the 68060 but an fpga cpu.
I don't think PPC systems and the Natami really compete with one another. I love to have a new 68K system, but its not going to be my main computer.
The Natami should be competitive with the low end PPC in the SAM. The clock speed is about 1/3 but CISC does more with less while having similar memory bandwidth and more helper processors with no slow buss to go through. I think the code will be more efficient too. The high end PPC (except IBM Power processors) is not getting faster very fast at all. On the other hand, fpgas are getting cheap fast allowing the performance to grow. It's price to performance ratio that will likely win the battle in the end. The x1000 sounds like the nicest most powerful PPC system yet but I think the price to performance is too far off to be successful.
