We have essentially pencilled in a Nexus tablet debuting at Google I/O next month, but a benchmark that appeared over at Power Board today may have told us much more than we thought we knew. The Tegra 3 is there, but clocked at 1.3GHz. Asus is the manufacturer. The 768×1280 resolution simply screams 7″ display. The name of "Nexus 7" also fits that bill. But what else do we have?
