# Graphic cards
Phyllome leverages 3D acceleration within guest operating systems extensively, in three different modes depending on the situation.
Phyllome leverages 3D acceleration within guest operating systems extensively, in three different modes depending on the context.
* **vfio-pci** : Passing through a complete physical Graphical Processing Unit (GPU) to the guest via the `vfio-pci` driver
* **vfio-mdev** : Sharing a fraction of a compatible physical GPU such as those using [single-root input/output virtualization](https://en.wikipedia.org/wiki/Single-root_input/output_virtualization) (SR-IOV), via the `vfio-mdev` driver
* **vfio-gpu** : Using some capabilities of the host GPU, via the `vfio-gpu` driver, which creates a virtual GPU as is used in Chromium OS and Spectrum OS
* **vfio-pci** : Passing through a physical Graphical Processing Unit (GPU) to the guest via the `vfio-pci` driver
* **vfio-mdev** : Create multiple vGPUs that can then be passed through to multiple guests. It does require a compatible GPU
* **virtio-gpu** : Expose capabilities of the host GPU to the guest via the `virtio-gpu` driver. Compatible with most GPUs but not many guests
