Hello list,

My OS:
$ lsb_release -cd
No LSB modules are available.

Codename: bookworm


How can I check the graphics card model of my computer and how can I
test the floating-point computing capability of the graphics card?

Thanks in advance.

In addition or alternative to Jeremy's answers, the following can provide a somewhat comprehensive operational status, useful in issue diagnosis:

inxi -GSaz

The inxi version's GPU output in Bookworm is partly broken, thus it is best to install or upgrade to the backport version, or the latest upstream version from:

sudo lspci -v | grep -A 1 -i "VGA compatible controller"

I don't think you need elevated privileges for that.

Not strictly, but with "-v" (and higher), sudo will give you more
to read :-)

IOW: there are attributes only the boss is allowed to see.

Without root you can get the model. For the floating-point
computing capability of the graphics card, I wouldn't know.
Does root with the "v" flag provide that info?

I have no idea what you are after, but serve yourself (caveat:
lowly hardware around here, so better try for yourself):

Fine. Then we can consider the case resolved?
