Nvidia SHIELD Android TV was announced this March with Nvidia Tegra X1 octa-core Cortex A57 + A53 processor. So far, I had not seen any Ubuntu or other Linux distribution port, but Michael Mirabel of Phoronix got remote access to a Shield TV PRO – model with a 500GB hard drive – running Ubuntu 14.10. It’s not clear who provided access, either Nvidia or third parties, but somebody posted an Ubuntu 14.10 port on XDA Developers Forums recently so it might be that one.
He obviously ran Phoronix Test Suite on the device, and compared to it some other ARM devices (Compule Utilite, Jetson TK1), MIPS Creator CI20, low power x86 devices (Compute Stick, Intel NUC with Celeron N2820), and an Intel Core i3-5010u NUC. The Tegra X1 platform easily beats all other low power platforms, and comes close to the Core i3 mini PC in most tests.
In the grand scheme of things, it was also compared to some Core i5 and i7 platforms with pretty decent results considering the price difference with these CPUs. You can access all results here.
However, not everything appears to be optimized, as Tegra X1 ranks close to the bottom for OpenSSL tests.
The Maxwell GPU is Tegra X1 should in theory also outperform the Intel GPU found in the Core i3 NUC, but AFAIK Nvidia has not released aarch64 drivers yet, so there’s no graphics acceleration right now.
