NVTOP stands for Neat Videocard TOP, a (h)top like task monitor for GPUs and accelerators. It can handle multiple GPUs and print information about them in a htop-familiar way.
Currently supported vendors are AMD (Linux amdgpu driver), Apple (limited M1 & M2 support), Huawei (Ascend), Intel (Linux i915/Xe drivers), NVIDIA (Linux proprietary divers), Qualcomm Adreno (Linux MSM driver), Broadcom VideoCore (Linux v3d driver).

NVTOP has a builtin setup utility that provides a way to specialize the interface to your needs.
Simply press F2 and select the options that are the best for you.
You can save the preferences set in the setup window by pressing F12.
The preferences will be loaded the next time you run nvtop.
NVTOP comes with a manpage!

nvtop --helpNVTOP supports AMD GPUs using the amdgpu driver through the exposed DRM and
sysfs interface.
AMD introduced the fdinfo interface in kernel 5.14 (browse kernel source). Hence, you will need a kernel with a version greater or equal to 5.14 to see the processes using AMD GPUs.
Support for recent GPUs are regularly mainlined into the linux kernel, so please use a recent-enough kernel for your GPU.
NVTOP supports Intel GPUs using the i915 or xe linux driver.
Intel introduced the fdinfo interface in kernel 5.19 (browse kernel source). Hence, you will need a kernel with a version greater or equal to 5.19 to see the processes using Intel GPUs.
INTEL SUPPORT STATUS
- Intel is working on exposing more hardware information through an
HWMONinterface. The patches are still a work in progress: see patch series. - The fdinfo interface does not expose the memory allocated by the process. The field in the process list is therefore empty.
The NVML library does not support some of the queries for GPUs coming before the Kepler microarchitecture. Anything starting at GeForce 600, GeForce 800M and successor should work fine. For more information about supported GPUs please take a look at the NVML documentation.
NVTOP supports Adreno GPUs using the msm linux driver.
msm introduced the fdinfo interface in kernel 6.0 (browse kernel source). Hence, you will need a kernel with a version greater or equal to 6.0 to see the processes using Adreno GPUs.
NVTOP includes some initial support for Apple using Metal. This is only supported when building for Apple, and when building for Apple only this vendor is supported.
APPLE SUPPORT STATUS
- Apple support is still being worked on. Some bugs and limitations may apply.
NVTOP supports Ascend (testing on Altas 800 (910B)) by DCMI API (version 6.0.0).
Currently, the DCMI only supports limited APIs, missing PCIe generation, tx/rx throughput info, max power draw etc.
NVTOP supports VideoCore (testing on raspberrypi 4B).
Supports GPU frequency, temperature, utilization, per-process utilization, GPU memory usage, and H264 decoding utilization.
On non-raspberry pi os, you need to use the linux-rpi kernel, ensure the presence of the /dev/vcio device, and have access permissions to the /sys/kernel/debug directory.
Several libraries are required in order for NVTOP to display GPU info:
- The ncurses library driving the user interface.
- This makes the screen look beautiful.
- For NVIDIA: the NVIDIA Management Library (NVML) which comes with the GPU driver.
- This queries the GPU for info.
- For AMD: the libdrm library used to query AMD GPUs through the kernel driver.
If your distribution provides the snap utility, follow the snap installation process to obtain an up-to-date version of nvtop.
A standalone application is available as AppImage.

sudo apt install nvtop
A PPA supporting Ubuntu 20.04, 22.04 and newer is provided by
Martin Wimpress that offers an up-to-date
version of nvtop, enabled for NVIDIA, AMD and Intel.

The build system supports multiple build types (e.g. -DCMAKE_BUILD_TYPE=RelWithDebInfo):
- Release: Binary without debug info
- RelWithDebInfo: Binary with debug info
- Debug: Compile with warning flags and address/undefined sanitizers enabled (for development purposes)
- The plot looks bad:
- Verify that you installed the wide character version of the ncurses library (libncursesw5-dev for Debian / Ubuntu), clean the build directory and restart the build process.
