Is there an application or tool that can monitor GPU performance on OS X? Specifically I would like to see the current speed/utilization and temperature of the integrated NVIDIA chip.

For Windows, there is CPU-Z and MSI Afterburner. I cannot find anything for OS X, not even an NVidia control panel app.

You can use Activity Monitor that comes with MacOS in Applications>Utilities

Choose Window>GPU History

or press ⌘4

GPU monitoring Mac

Update: MacOS includes the in-built powermetrics command line tool which allows for access to varity of performance and power info. e.g. to obtain running GPU info every 5 seconds:

sudo powermetrics --samplers gpu_power

To access all info (inluding temperatures for certain devices) run it without any arguments. Or to sample GPU usage for one iteration (-n1 over say 200ms (-i200):

sudo powermetrics --samplers gpu_power -n1 -i200

The Intel Power Gadget also allows for monitoring of Intel GPUs, along with other measures of power usage for CPU, temperature, etc. It also has command line tools that provides for logging to a file.

I'm using iStat Monitor, which is a really great app.

GPU monitoring is also supported. Here i found YouTube Review (not related with me, have further searches for better/other reviews)

  • Thanks for the answer. I tried iStat, and it was not informative when the Intel chip was used - no processor usage. Even for NVidia, there is only fps, memory and processor usage.

    All the temperature monitors are put together in Sensors in iStat

  • I tried it with my 27" iMac with the NVidia GeForce GTX 780M and it shows the GPU processor usage as well as fps. Works great!
