Here you can see that even if I open an image viewer and a terminal, my VRAM usage is only 138 MB.
If I close the image viewer then the VRAM usage lowers to 135 MB. These seem like pretty good values for the Radeon RX 7600.

What is the VRAM usage of your GPUs when you have no apps open?

Seems like your OS is responsible for being a lot more frugal with VRAM at idle. On win 10 I'm usually somewhere around 1 gigabyte, give or take a couple hundred megabytes

959/135=7.1

Seems like a big difference to me.
I thought that it would be considerably higher for most persons because I use a very lightweight setup.

I've seen it up to 3GB (that one on HWiNFO64) as I use the PC overtime for many hours, but its hardly a problem. Never cared really

Can we see the RX7600 on HWiNFO64?

I think that Windows will have the highest VRAM usage, but Linux with KDE Plasma or Gnome will probably also use more VRAM than 135 MB.

If I open a 3D shooter with outdated but decent graphics then I see 4xx MB of VRAM.
So I can play a fun 3D shooter with less than half of your VRAM usage.

In your case, if you have 24GB of VRAM, then you are never going to see a VRAM shortage.

The most popular GPUs according to the steam hardware survey:
#1 RTX 3060 (has 8GB models)
#2 GTX 1650 (4GB VRAM)
#3 RTX 3060 Ti (has 8GB models)
#4 RTX 3070 (has 8GB models)
#5 RTX 4060 (has 8GB models)
#6 RTX 2060 (has 6GB models)
#7 RTX 4060 Laptop GPU
#8 GTX 1060 (has 6GB and 3GB models)
#9 RTX 3060 Laptop GPU

If you have high VRAM usage you also have more code that can be abused by a hacker.
A codebase that is 7 times larger also has 7 times more vulnerabilities for the same amount of bugs per amount of code.

I've been checking this recently, I tested with two cards RX 570-4G and GT 740-2G. The RX 570 uses more memory (allocates more video memory) than the GT 740 2G. Maximum usage was +- 850 MB in non-3D applications (browser, youtube...) for the RX 570 and for the GT 740 Max +- 700 MB.

Linux Ubuntu (Gnome) 24.04 when turning on and without apps GT 740 +- 145 MB, RX 570 +- 250 MB

Win 10 GT 740 attachment

Need to reconfirm, but I think XOrg - and nothing else - takes 4MB on the dGPU's VRAM, with the iGPU enabled and plugged in. Ubuntu 24.04.

It's good for when you really do need all that VRAM.

Another curiosity is that the RX 570 is more dynamic in responding. For example, a YouTube video in 4K. RX 570 average usage is difficult to define, on average it was about +- 10% , with peaks of 50%, 80% and even 100% GPU usage with the CPU constant at 50% usage.
The GT 740 remains constant with 15% usage in a 4K Flash video, in this case the peaks in usage went to the CPU.

My VRAM usage on Windows 10 with a 6750 XT is usually between 1 and 2 GB, sometimes a touch more after closing a game with high requirements.

VRAM usage depends a lot on operating system (Windows seems to use a lot) and your graphics card (Windows will use more the more you have).

O uso de VRAM depende muito do sistema operacional (o Windows parece usar muita) e da sua placa de vídeo (o Windows usará mais quanto mais você tiver).

Ou para compensar o baixo desempenho da formatação NTFS no disco rígido. A formatação Linux EXT4 é superior
