Ok , I am pretty knowledgeable when it comes to GPU stuff but their are a few elements I don't fully get. This is partly because I don't have a frame of reference to go by.
Ok , here goes what makes a GPU better then others is the below defining factors
screen drawning rate 60 hz , 120hz , now 240hz offered.
resolution for HD if it supports 1920X1080 p progressive not interlace where the screen is only half drawn each frame
output ports if it has on it DVI , HDMI , RCA ,...etc and how many it has on the card.
contrast ratio's and color space stuff.
the speed of the GPU processor
weather it can be plugged into PCI-eX or just old PCI bus which is slower to get data from the mobo to the gpu
the amount of dedicated memory on the GPU itself
I can pretty much determine what a graphics card is going to cost by just knowning this stuff. But what the only defining fact that I don't fully understand is what the difference in the dedicated memory being 512mb , 1gb , or 1.5gb?
I know the more memory the faster things can run if you can fit it all into memory. But I have no frame of reference in what 512mb or 1gb or 1.5gb ...etc feels like for graphics cards and how much is needed???
Any help in this area would be great.
Main question is how much memory will a graphics card generally need / uses and will the best GPU need 1.5 or 2 gb of memory for what they have to do?
If I had 3 GPU all with the top of the line stuff and the same stuff except one had 512mb , one 1gb , and the last one 1.5 gb. Would you see a significant differences?
Even for gaming if every thing was equal the frame rate would all be the same and the HD would all be the same just curious if the memory would still have a huge effect?
I guess 1920 X 1080 = 2073600 approx => 2GB so if you had a 2 GB of dedicated memory you could almost hold each frame in dedicated memory on the GPU all at once and never use system memory. If this has any significants?
