Now that the LG Optimus 2X has been announced to the world, people are wondering just how well it will perform. Well, to answer these questions, NVIDIA just demoed the device running intensive games up against the Samsung Nexus S.

LG's Optimus 2X was the first NVIDIA Tegra 2 powered "superphone" to be announced, though we know it won't be the last; Motorola has since announced its own dual-core Android device, the Motorola ATRIX 4G. We caught up with NVIDIA and spent some time with the Optimus 2X earlier; check out our first impressions after the cut.

NVIDIA has developed an Android Skype HD video calling reference platform, using the VoIP company's SkypeKit SDK. The implementation, demonstrated at NVIDIA's CES 2011 press conference today on an Android tablet, relies on Tegra 2's native high-definition video processing capabilities, and promises cross-platform HD video calls.
Tegra 2 isn't new, but NVIDIA is hoping that 2011 will be the year that the dual-core mobile processor comes into its own. Last we heard of "superphones" it was Google trying to brand their Nexus One as such; now NVIDIA is seizing on the title to describe devices packing multi-core CPUs, speedy GPUs and frugal power requirements, the first device being LG's Optimus 2X. To help users pair up superphones with apps worthy of Tegra 2, NVIDIA is also launching its own software tool.
AT&T has announced the world's most powerful smartphone, the dual-core Tegra 2 1GHz Motorola ATRIX 4G, that like the Samsung Infuse 4G will use the carrier's HSPA+ network. The Android 2.2 smartphone has a high-res 4-inch qHD display, and will optionally come with a super-thin "Webtop" laptop dock - complete with an 11.6-inch display - for when you need to do more text entry.
