This page contains information about GPU algorithms supported in XGBoost.
To install GPU support, checkout the :doc:`/build`.
.. note:: CUDA 8.0, Compute Capability 3.5 required
The GPU algorithms in XGBoost require a graphics card with compute capability 3.5 or higher, with
CUDA toolkits 8.0 or later.
(See `this list <https://en.wikipedia.org/wiki/CUDA#GPUs_supported>`_ to look up compute capability of your GPU card.)
