FUD Zilla writes an unknown entry in the results page of the GFXBench benchmark suggest NVIDIA may be preparing to release a tablet or a phone/tablet hybrid. Listed as the NVIDIA Tegra Note Premium, the device is only slightly slower than NVIDIA's Shield handheld console. The Android 4.2.2 based device features a NVIDIA Tegra 4 SoC clocked at 1.8GHz and offers a resolution of 1280 x 800 pixels. It's unknown whether NVIDIA will launch this device under its own brand, another possibility is that this is intended as a reference design for OEMs.
At Computex 2013 back in June, Nvidia showcased a rather unique device that was used to demonstrate pressure-sensitive functions of a stylus and which might be the device that showed up in the GFXBench results. The 1280x800 resolution is not impressive and far off from what the competition currently has to offer, but then again Nvidia might want a cheaper tablet or phablet on the market.
In any case we will surely keep an eye out for Nvidia's Tegra Note Premium, whatever it turns out to be.
