Last week, NVIDIA GM Mike Rayfield noted that the company’s upcoming quad-core Tegra 3 processor would be unveiled at Mobile World Congress next month. Keyboards around the world were subsequently covered with drool. Further information was revealed on Sunday, however, when a purported NVIDIA roadmap was uncovered. The roadmap brings new details to light surrounding the beastly Tegra 3, and it also reveals a third chip that will bridge the gap between NVIDIA’s Tegra 2 and Tegra 3 processors — the Tegra 2 3D. Due to enter production this quarter, the upcoming Tegra 2 3D will feature two cores and speeds up to 1.2GHz. As its moniker might indicate, the Tegra 2 3D will also support 3D displays on both tablets and cell phones. The Tegra 3 will feature speeds up to 1.5GHz, and its four cores will even be capable of powering Blu-ray video playback on tablets. Samples will become available in the fourth quarter of this year according to the roadmap, which means Tegra 3-powered devices will likely land in the first half of 2012 at the earliest.
