Amid the swirl of gray suits and blazers in Hall One at Mobile World Congress, you’ll find the NVIDIA booth decked out in trademark lime green against white walls. Staffers in pressed solid black, sporting the green claw logo, spurred onward by an in-house espresso machine, take hundreds of customers, media and partners through some of the best world’s best mobile technology.

Here’s what they’re seeing across the booth’s three main areas: a raft of new game titles optimized for Tegra 4-PLUS-1 quad-core mobile processors, a wave of new super phones powered by Tegra and a collection of new tablets driven by Tegra 3.

Against one wall, an oversized monitor shows Sega’s Sonic the Hedgehog 4: Episode II, running in HD from an ASUS Transformer Prime, with four wireless gaming controllers. It’s an irresistible scene for gamers and ordinary civilians alike, who stop by to pursue foxy Tails, or have a go at challenging others  in a neighboring multi-player title, Shadowgun: Deadzone.

Nearby is a pod showing off some of our five spanking new Tegra 3-powered phones. Those on display include the LG Optimus 4X, which is getting plenty of press for its 4.7-inch screen; the ZTE Era; and the ZTE Mimosa X, NVIDIA’s first phone for the mainstream of the market.

The Mimosa X combines Tegra 2 with an NVIDIA Icera 450 modem, based on technology we acquired in mid-2011 through the acquisition of UK-based soft-modem maker Icera. It’s an indicator of things to come at NVIDIA when the Icera modem gets integrated into a future generation of Tegra.

Closer to the warren of meeting rooms that run the length of the boom and seem to require a turnstile to accommodate their regular turnover, are some of the new tablets we’re powering. Those getting the most eyeballs include two 10-inchers – the ZTE PF 100 and the competitively priced Asus Transformer Pad 300 – as well as the Toshiba 7.7-inch and the ZTE T98  7-inch tablets.

Then, up a sleek set metal stairway is the booth’s upper deck. While the meeting rooms there are humming, nothing’s moving faster than Grady behind the espresso machine, who’s busy helping to fuel the activity below.
