A new spec leak from @evleaks suggests that the slate will come with a 64-bit Tegra K1 processor, though it’s also being speculated that Google is also testing out the Snapdragon 810 chip too. Meanwhile, it’ll feature 5GB RAM if the leak holds true to the final version. It is worth pointing out that @evleaks mentions that this figure in non-final, so we have to hope that Google goes with this rather than dropping down to a more standard 2GB or 3GB.
Other suggested specs include a sharp 2560×1600 screen, an 8-megapixel snapper and BoomSound speakers, along with an aluminium body. The Nexus 9 is shaping up nicely, though we do have to wait and see what specs Google decides to go with for the final version.
