Ok. So building on that we can see that the X1000 processor is a PWRficient PA6T-1682M from P.A. Semi.
I believe a lower cost single core chip will be available in an X500.
Assuming it is pin compatible, a single core PA6T-13xxM could lower the costs, and allow them to reach some sort of economy of scale with the motherboard.
Also assuming it is pin compatable, chips with up to 8 cores(right now) and 16 in future could fill an even higher specced line-up perhaps designated X2000 and beyond.
I would kinda think specifying the amount of cores by having the model number divisible by 500 would make more sense than it did in classic days.
I also assume Varisys are supplying this board for what they see as their key markets:
Video and image processing
Telecommunications
Military and aerospace
Radar and Sonar
Speech recognition
Industrial Control
Vetronics
So, perhaps leveraging these markets could help lower costs.
