GPU
Uses Nouveau for GPU acceleration although at the moment it's broken on upstream Mesa. (See https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/2960)
Tegra T132
A variant of the K1 with dual 64 bit 2.5GHz Denver cores exists called the T132, however this was only ever used in the Nexus 9 and low volume prototypes. Aside from the CPU cores and some clock tree changes it seems to be identical to the T124.
