uh, you do realise that Project Denver is not Tegra. Their new chip is nothing to do with Tegra at all.
And you do realise that for all of that, Tegra throughout it's entire life was used in sweet fa. Just like it's predecessor Project Denver is likely to share the same fate unfortunately. The market for these things has all but moved on.
As much as I have a soft spot for alternative cpu archs, ARM has less and less of a place outside of cellphones and embedded sectors - neither of which need something for the most part along the lines of Tegra or Denver.
Atom has all but subsumed the high performance STB/Nas/home server markets and when coupled with Nvidia's ION2 chipset makes for a remarkably potent system, especially in it's dual core variants.
