It's a good day to be an Nvidia fan. The Tegra 3 quad-core system on a chip is said to be powering upcoming tablets from Acer, in addition to Asus, Lenovo and HTC. DigiTimes is quoting OEM suppliers, confirming that all the major Android tablet manufacturers will have their own quad-core Tegra machines in the future. Specifics are hard to come by, but we already know that both Lenovo and HTC are hard at work on their new models. Samsung is prepping its own new tablets, likely updating its extensive range with next-generation Exynos chips. According to DigiTimes, Acer and Lenovo's offerings will fall between $459 and $599, hitting pretty close to the Asus Eee Pad Transformer Prime's $499-599 range. Look for Acer to undercut its competitors by a considerable margin, as they like to play the bargain angle. Lenovo's latest tablets, the 5, 7 and 10-inch s2005, s2007 and s2010, respectively, and Acer's A200 is making the rounds, but none of these devices are expected to bow with Tegra 3 chips. Lenovo's K2 tablet, however, has already been benchmarked with its Nvidia hardware, and may even come with a jaw-dropping 1920 x 1200 10-inch display panel.The Acer A700/A701 may have the same beastly resolution when it comes in, also using a Tegra 3. The power of the new architecture is hard to deny - just check out the latest demo from Nvidia. The Android tablet world is going to heat up in the next few months, and we can't wait to see what kind of new hardware is on display at CES in January.
