3. Will this Tabor board out perform Sam boards?
Its great news, whats the price?
Yes, but only slightly on one core (Tabor is dual core). However, it has an incompatible FPU which has to be run in software mode, making all FPU intensive work a whole lot slower than the SAM (which is also the reason MorphOS Team isn't interested in porting their OS to this board). I also wants to mention that both lacks Altivec.
The price is unknown, but it's said to be cheaper than the SAM.
