1gb vs 2gb graphics cards
What really is the difference? It's just more money to waste your money on

The 750 is 1gb and the ti is 2. But still, it will have good quality as it is more than 512mb right?


The higher the resolution you can play a game, the better. So yes.


Thank you so much for your help! Now I know what card to get that will last for a long time, good frame rate and can run at good quality!

An explanation for the VRAM is actually how high it can perform well on the resolution, especially on Games.

If you get a 512MB VRAM from a GPU, there is a possibility that it will not perform well on 1080p resolution as it will also get RAM performance from your actual RAM.

The GTX750 has a 2GB GDDR5 VRAM. It can perform nicely on 1080p in most games on Medium to High.


Um...
I don't understand most of what you are saying, however the GTX750 has mostly 1GB models. Only one of the TEN cards at pcpartpicker are 2GB. It's the GTX750Ti that is 2GB.

And your definition of "nicely" and mine seem to differ. http://www.anandtech.com/show/7764/the-nvidia-geforce-g...


My mistake, it's a 1GB VRAM for GTX750.

To make it straight, have a 512MB GPU means that it can have issues with playing any sorts of games in higher resolutions like 1920x1080. The higher VRAM is, the better it performs in higher resolutions. Take it for example, a GPU with 512MB or 1GB of VRAM can't run well in 4k resolution, not like a GPU that has 4GB VRAM.

The GTX750 is okay but if I had $125 for that I'd stretch for an Asus GTX750Ti instead for $30 more.

How about gtx 750?


Probably more than 1GB is unnecessary.
I don't count scenarios where someone cranks up the quality settings but is getting 20FPS average.

You'd have to monitor VRAM usage in Windows 7 or previous with the desktop visuals disabled (Windows should use under 40MB of VRAM), then run various games with the quality settings giving a minimum of 30FPS and see if you run out of Video RAM.

I doubt that would happen.

Um..

It depends completely on the card chosen. When you have an HD7750 for example, to keep frame rates high enough you need to keep anti-aliasing and other settings to reasonable levels. This uses less VRAM.

That's why VRAM amount scales roughly with the power of the GPU. So an HD7750 1GB makes sense, an HD7750 2GB arguably does not.

(Also, there have been a great number of MISTAKES in testing VRAM usage. Windows can use a lot of VRAM itself but then this gets cleared if the game needs it. When BF4 was tested on 3GB video cards they noted "2.2GB is used so 2GB is not enough" but failed to realize that BF4 was actually maxed at 1.8GB. The rest was used by Windows and would have been swapped out if needed.)
