More memory or GDDR5?

[shreejan86]

When buying a graphics card what should one consider? Some of the cards have GDDR5 but have low memory around 512MB and others are 1GB DDR3 cards so what should you consider?? Is it better to have GDDR5 card with low memory or a DDR3 card with more memory?

Depends which cards, It would help if you posted which cards.

Just wanted to know what offers better performance? So can you explain about the diffrences between having more memory or GDDR5 technology?

Well, GDDR3 is approx. 2 times WORSE than GDDR5, but Memory and clock speeds make up for a lot of that, meaning it really depends on which cads you are choosing.

The type of memory is not that important -- it is a combination of the type of memory, the speed it runs at, and the memory bus width that combine to make the memory throughput (which is the more important item - since it is the total amount of info the card can process per second that matters not how it processes it !!) and as far as amount of memory on the card the importance of it is also more a factor when combined with the rest of the specs of the card (ie. putting 1 or 2GB. of memory on a card that can not use it effectively is wasted as much as having only 512Mb on a faster card that could support 1GB.) -- so as stated it is hard to give an exact answer to your question as it is the combination of all the parts and the usage it is being used for that leads to the performance of any specific card. so would need more specifics to provide any useful info.

I am doing the same thing as the person who created this thread. The cards I am bouncing between are;

The XFX card looks better....has better speeds & such....better bandwidth. Looking to buy a second later for x-fire too. But the HIS card is GDDR5....and the XFX card is ddr3.....so......help please....

DDR5 has double bandwidth of DDR3, go with HIS
