NVIDIA is launching a full-frontal assault on Intel, its burgeoning MID market, and smartphone makers with its forthcoming "mobile computer on a chip" architecture, dubbed Tegra. We've shown you snippets of what this would look like before, but plans are now well underway to take this technology mainstream, with numerous partnerships, and products planned for Q4 2008 and Q1 / Q2 2009. We had a chat with the company, and we've got a slew of info about the chips and their intended products after the break.

Update: We've added some videos from World Mobile Congress showing off the UI.

Intel may have sold its mobile chip unit to Marvell, but it seems that the company hasn't entirely given up on the mobile biz, with the company recently detailing plans for an x86-based system-on-a-chip. According to HKEPC Hardware, the so-called 'Tolapai' unit will be based on Pentium M architecture, and pack 256KB of L2 cache and support for DDR 2 memory, along with a full compliment of integrated connectivity options, including PCI Express, USB, SATA, Gigabit Ethernet, RS-232 and a cellular link, among other goodies. The initial lineup will apparently come in 600, 1,066 and 1,200MHz varieties to start with, boasting a power consumption of 13-22W, and support for Linux, FreeBSD, and Windows XP Embedded on the OS front. While Intel will first be aiming the system-on-a-chip at embedded applications, as Reg Hardware speculates, it would seem to be just as applicable to handhelds and other mobile devices in need of a little more power. What's not so clear, unfortunately, is when we might actually see a device running on the thing, although the system-on-a-chip itself will supposedly be ready by the end of the year.
