512mb vs 1gb

How much better is one than the other?
Comparing a 130M with 512mb and a 130M with 1gb mainly, but interested all around as well.

 

I may be off the mark here but i very much dout a GT130 has the power to display high end GFX at the resolutions that 1gb of memory would become useful.

 

Yep, 1GB won't perform any better than the 512MB in games.

 

The GT130M has a 128-bit bus, so, really, any amount of graphics memory above 256MB is largely pointless. 512MB is still arguably useful for playing at higher resolutions, but 1GB is completely pointless, as the GT130M would choke up at the higher resolution gaming that would actually use that much memory.

 

BUT, it will help some when playing at very high resolutions.(I'm talking about graphics cards in general, not the GT 130M)IMO the 1GB version should beat a 512MB(not by much) at 1920 by 1200 res.

 

basically a GT130M is 9600M GT replacement and is just more cooler. It's really needs only 512 MB memory and like he said 1 GB is just for show and is useless.

 

low end video cards with huge amounts of ram is just a play towards people who have no clue what they are doing. They see a high amount of RAM and automatically think the card is good which is what the company wants you to think. In reality a low end card cannot push enough pixels to play games at high resolution so that means it will never even use the full RAM on the card when playing games. When choosing a lower end card get the ones with a more reasonable amount of ram and higher clock speeds and you'll get better performance out of it.

 

As others have said, in the GT130M's case, it's useless and there'll be little to no performance gain at all.

In general, for low end GPUs, it's also useless.

For high end ones, it's only useful if you intend on playing at higher resolutions. If you stick to lower resolutions, only very VRAM demanding games will show any performance increase.

 

My 4870 actually uses the 1gb of VRAM, because it can push enough frames at 1920x1200 to use it.

As others have said it is a marketing gimmick for lower-end cards.

 

Note please, the previous posters are correct in telling you that 1GB on a 130M isn't really that useful.

Basically a 130M is never going to give playable framerates at the resolutions and/or texture complexities that would actually use 1GB of texture RAM.

Yes, a 1GB 130m WOULD be better than a 512MB 130m for higher resolutions and texture complexities, but who really cares when we are talking about "slideshow" framerates?

Thus the more RAM isn't necessarily useless, its just not going to be practical or worth the price difference.

 

alright, thanks

 

I would actually go a step farther and tell you that the 512mb one is BETTER. There is a good chance (from empirical data and guesswork) that the 512mb one has DDR3 memory and the 1gb one has DDR2, which would make the smaller memory card perform a good bit better (~15-20% I Think). You should try to verify the type of VRAM if possible.

 

hey man, get 1gb, you get bragging rights

 

lol money>>>bragging rights

 

and certificate of stupidity....*cough**cough*....it is wise to research something before start to brag about it

GT130M even have start coughing at WSXGA+ resolutions , why would people want to play at WUXGA ... sacrificing framerates for the sake of image quality..
