So you want to see what a rooted Nexus 7 with a custom kernel has the potential to do performance spec-wise? How about a blistering 164GHz scoring over 7000 on Quadrant and scorching practically any other quad core device you can purchase anywhere in the world today. While there's a host of developers working on custom ROM's and kernels for the Nexus 7 the current crown goes to 'Trinity Seven' (Der Kernel By Morphic)
who's achievement in Quadrant is even more impressive because his kernel also offers improved battery life. He achieves this by using the Trinity Kernel Toolbox
which let's you ratchet up all four cores of your Nexus 7 to 1.64GHz when you need the horsepower say while playing a game but also allows you to wind those cores down and underclock them to give you outstanding battery life.
In fact you can put the device in 'deep sleep' mode which despite the name let's your run your tablet in an ultra low power state that after 12 hours still gives you tons of battery life. Now it goes without saying that to take advantage of custom kernels such as this you need to Root
your Nexus 7 and for most the added performance will be more of an ego booster than a practical benefit. Still it's nice to know that as far as price/performance goes...our $199 or $249 baby is the fastest tablet on the block...and for less than half the price of its competition that puts a smile on our face.
