They always say like: GTX 980 2GB, GTX 960 GB, ...
But what is that GB?
Decicated VRAM, or normal VRAM?
And how much of each?

Normally it`s the VRAM on the video card.

Wow that's horrible!
I have a GTX 650 with 4gb VRAM and 1gb dedicated.

Not sure I understand this. Is this a desktop GPU? If so, if it has 4 GB VRAM, that's a good thing. If this is a laptop, then I can see the point.

The thing is, has your video card it`s own memory or shared memory?

Wait... what?

All memory on your video card is by definition dedicated video memory.

And i'm not so certain that GTX 650 came with 4GBs of memory. At least not according to this:

Well, my GTX 650 has 1 GB. So I doubt this too!

The memory on your video card is super-fast and communicates with a slew of processors that can make crazy fast graphic-specific computations. The more memory you have, the more detailed textures and higher resolutions you can support (among other things).

If you have an integrated video processor on your MOBO (or a new LGA1151 processor which have the video processor attached to every processor), and you have a 4GB system and your system is using 1GB for video, then you'd be able to use 3GB for your applications (Windows uses 2 of those, so 1 for your apps) and 1GB for your video.

He probably means 650M (shared memory). http://laptopmedia.com/video-card/nvidia-geforce-gt-650m-4gb-ddr3/

NO, 4GB must be your PC system RAM and the 1GB GDDR5 is your VRAM. PC RAM is normally DDR3 / DDR4. VRAM is normally GDDR5 / GDDR3 (very rare now, commoner on older cards).

Ah, yes, that would explain everything. Thank you!

Oh sorry, so those 4gb is ram that the GPU can use?
I'm quite new to all of this...

that 4gb can't be VRAM :P

From your previous statement, it looks like the graphics card has 1GB actual RAM. This is the very fast dedicated graphics RAM that you want. The 4 GB is likely shared (is the card actually a 650M, as suggested?) Shared memory is much, much slower and not desired for gaming. So, the more dedicated memory a graphics card has (memory actually integrated onto the graphics card), then better.

I'm pretty sure you are right.
I am quite new on all of this and thus I asked the question.
So the GB that's advertised is actually VRAM and not shared RAM?

So shared RAM is RAM that is shared with the GPU and the RAM itself?
