Note: Irrespective of the card, the nouveau driver is likely to crash the user session, at least in GNOME under Wayland on a Guix System, a few times before continuing relatively stable untill next boot. Also, some artifacts or blurr may appear in some GNOME applications. Not observed in games or other applications.

The card is redesigned around the old NVIDIA GT 730 chip, so an older card with the same chip could be considered instead. It may make sense to buy this card if you need 4 HDMI ports or if you like the card being passively cooled and silent. A multiple monitors setup probably works but was not tested.

On a system with Mesa 25.1.3 shows OpenGL 4.3 with no Vulkan. OpenGL 4.6 and Vulkan for Kepler family of GPUs is still in development in NVK driver in Mesa: https://docs.mesa3d.org/drivers/nvk.html.

On a system with Mesa 25.2.3, there is Vulkan 1.2. It was predicted that there will never be a higher version for Kepler GPUs.

With Vulkan, it is possible to export NOUVEAU_USE_ZINK=1 to test NVK driver instead of Nouveau. While the experience is more smooth, some widgets do not render and there are system freezes.

$ glxinfo | grep "Device\|profile version"
    Device: zink Vulkan 1.2(GeForce GT 730 (NVK GK208B) (MESA_NVK)) (0x1287)

OpenGL ES profile version string: OpenGL ES 3.2 Mesa 25.2.3

No hardware accelerated video decoding is possible despite some capabilities being present and even reported by vainfo. This is expected considering that the feature requires "firmware from the binary driver" in Kepler cards according to the nouveau driver feature matrix: https://nouveau.freedesktop.org/FeatureMatrix.html. mpv and ffmpeg fall back to CPU for rendering.

There are no apparent issues when suspending to and resuming from "deep" state.

The card probably supports 4K. When tested with a UHD monitor instead, the following resolutions can be confirmed.

The frequency depends on the resolution, and possibly on the monitor. Tested: 2560x1440@59.95 and 1920x1080@74.97.

The nouveau driver does not support automatic reclocking for this card. This is expected per the nouveau's power management matrix: https://nouveau.freedesktop.org/PowerManagement.html. As a result, the card runs in a conservative power state as described in this section, unless reclocked manually as described in the next section.

Graphics in GNOME run with acceptable smoothness.

As an example, OpenArena is playable even at "Very High Quality" in-game settings profile with frames per second (FPS) around 30 on average depending on the scenery. However, that profile chooses a resolution similar to 1024x768, while increasing the resolution even at "Fast" profile often results in an uncomfortable drop in FPS.

To provide a general idea, here are some results of a synthetic test, which does not go smoothly. Note the "terrain" rendering test below, which somewhat matches the OpenArena observations above.

This card has experimental support for manual reclocking with nouveau. Here is how to test it.

# cat /sys/kernel/debug/dri/0/pstate
07: core 405 MHz memory 810 MHz
0f: core 653-901 MHz memory 5010 MHz AC DC
AC: core 901 MHz memory 5009 MHz
# echo 0f > /sys/kernel/debug/dri/0/pstate
# cat /sys/kernel/debug/dri/0/pstate
07: core 405 MHz memory 810 MHz
0f: core 653-901 MHz memory 5010 MHz AC DC *
AC: core 901 MHz memory 5009 MHz

The result is immediately noticeable in GNOME's smoothness. OpenArena runs at around 90 FPS at "Very High Quality" profile customized with 2560x1440 resolution. Some results of the same synthetic tests as above are below for comparison.

To enable this mode at boot, one could add the following kernel parameter.

nouveau.config=NvClkMode=15

The way to do it may depend on the distribution. Here is a snippet from an operating-system declaration on a Guix System.

  (kernel-arguments (cons* "nouveau.config=NvClkMode=15"
                           %default-kernel-arguments))
