Question about Manycore processor- "Tilera"

Hello, all. I am not sure is it suitable or not that I ask this question here. My question is about "Tilera", a new multi-core processor provider, however, they call themselves "Many-Core" to separate from RMI, Cavium, etc. Tilera claims that their processor have a 2D mesh so they can put more Cores(from 36,64 to 1K) in one Chip, while Cavium only with 1D bus, so Tilera think they have a much higher performance. My question is: 1 Is it true that Tilera revolutionarily improve the performance of multi-core(or Many-core) processor? 2 If you make the choice between Tilera and Cavium, what do you prefer? Why? Devin. BTW, its website is http://www.tilera.com/
