If you didn't believe the Tegra hype -- 25 days audio, 10 hours of 1080p video on single charge -- already then pull up a stool, son, NVIDIA wants to tell your a story. TechVideoBlog sat down with Gordon Grigor, NVIDIA's Director of Mobile Software to see Tegra's little Atom smasher in action. So sit back while Gordon smoothly streams a 720p MSN HD trailer off the web (over WiFi) then switches over to Firefox to take Flash for a spin at full-screen. Gordon also clarifies earlier confusion over Tegra's ability to handle HD video; see, the Tegra 600 can do H.264 video at 720p while the Tegra 650 can decode 1080p. Gordon also gives some more insight into memory configurations. It seems that the OS (either Android or Windows CE in single or dual-boot configurations) will be embedded with minimal on-board storage like those early Eee PCs. RAM will also be limited to about 512MB on base units going as low as 256MB and as high as 1GB in future (unannounced) devices. A 512MB model limits Firefox to about 3-4 opened tabs at a time. All of this is meant to keep prices down below $200 (or less when subsidized by carriers). Also of note is how the Tegra's GPU assists in rendering pixels anytime they appear on the display. In other words fonts, Firefox pages, scrolling, and of course video playback all benefit from an extra boost by the GPU. Check the video after the break to hear Gordon make some not so subtle jabs at Intel's relatively power-hungry Atom processor.

Update: It's worth mentioning that the first Tegra smartbooks are expected to launch in October according to Gordon.

NVIDIA's really promising the moon here, and if they even halfway deliver we could have a real "game changer" (as they say in the business) on our hands. What's on offer is a theoretical $99 slide-out keyboard MID, running a Tegra 600 chipset and Windows CE -- NVIDIA, as usual, offers the innards and the concept, but will leave it to manufacturers to create (and price) the actual units. The device could handle HD video playback, "days" between battery charges and always-on wireless connectivity. This form factor lands in between NVIDIA's Tegra APX chipset for smartphones and ION GeForce chipset for netbooks, and if it actually delivers it seems like it could actually make MIDs viable in the market. Of course, there's the question of what sort of Windows CE skin it'll take to make this fun to use for the target market -- perhaps the fact that Tegra is coming to Android in the near future is enough to make this all moot, but we're willing to give the $99 MID a fighting chance.

Yesterday we told you about NVIDIA's new mobile platform, Tegra, and today, we've got some videos from the company showing off the system, and giving you a good impression of just how much less juice this architecture uses compared to the competition. Check the videos after the break demonstrating the systems' lean energy needs, HDMI output capabilities, blazing fast gaming, and that fancy UI we keep telling you about.

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.
