[FEAT] Detect GDDR VRAM type for dedicated GPUs.

[Get-Newsletters-Int]

Wanted features:

Detect what type of VRAM dedicated GPUs are using, for example GDDR5, GDDR6, GDDR6X etc.

Motivation:

It is important information about graphics cards, that companies making them often show prominently on the model page.

Doesn't seem to be possible because no public APIs of Nvidia / AMD / Intel drivers report this info AFAIK.

Do you know any open-source program can report it?

[Get-Newsletters-Int]

Nope, I think only GPU-Z detects it, but no idea how, maybe they don't and they do a database lookup instead.

There is no API for this, so you need a database that can infer the VRAM type from the GPU model name. Luckily, pretty much all GPUs of a same model use a single VRAM type (e.g. all GTX 1080s use GDDR5X).

A few GPUs have different VRAM types depending on VRAM size (such as the Radeon HD 7750 or GeForce GT 1030), but this practice hasn't been seen in GPUs released since 2016 or so. In this case, I'd return the most commonly found VRAM type (GDDR5 and DDR3 respectively). If you really want to, you could get fancy by picking the correct VRAM type depending on VRAM size:

• HD 7750 1 GB: GDDR5
• HD 7750 2 GB: DDR3
• GT 1030 1 GB: GDDR5
• GT 1030 2 GB: DDR3

Integration with GPU-Z via SDK would be amazing tbh.

There is no API for this

I think it is (but more likely uses DB). TechPowerUp says: "We also offer a GPU-Z SDK, which is provided as simple-to-use DLL with full feature set that can be used from C/C++/.NET and others."

Maybe somebody could write to them and get SDK? It should include some sort of a database too, so later we should be able to create linux version using it

GPU-Z's SDK is proprietary and Windows-only, and therefore not a good fit for an open source CLI tool that aims to be portable.

It should tell you in the vBIOS. Maybe poke a few tech YTbers that play with overclocking, if you can't get ahold of KingPin directly.
