VRAM Usage Different for Different GPUs. Why?

[Hammtastic]

Hello everyone, I recently came across something that I didn't understand, maybe someone here can enlighten me. So me and a buddy have 2 different GPUs, a 2070 Super and a 6800XT. We both play at 1440p and we both have the same graphics settings for Warzone. At the same settings, I, with my 2070 Super, use around 6GB of VRAM, but he is around 12GB VRAM usage with his 6800XT. Why is that?

Some games will use as much VRAM as it realistically can to use as a cache for assets that might become necessary. I'm pretty sure Modern Warfare 2019 and Warzone handle things like this as it's relatively efficient for the game.

Different GPU architecture. Nvidia cards traditionally have better data compression for example.

What you're seeing is memory allocation. Game/window will allocate more on GPU with more VRAM.

If you want to check real usage you need program like Process Explorer, Special K tool or latest beta MSI Afterburner(you still need to set it up yourself)

I thought this. However I allowed Warzone to use 100% of my VRAM and it still only uses roughly 80%. 

 

So are you saying that the usage showing in the game is inaccurate?

Could be, check with Process Explorer.
