Hi,

I want to know how display resolution affects memory performance?

is there any calculation to working out what size of memory will work at which resolution etc.

e.g If I wanted to use 1280 x 1024 = 1.3 million pixel display resolution, what is the baseline MB of memory do I need.

I have seen a simple calculation but can't remember where.


thanks in advance.
 
System Memory such as 1GB/2GB/4GB

I'm trying to work out, if I'm viewing e.g 8mp image on 1.9mp screen (1680 x 1050), what is the minimum ram I need to view the image.

I need the formula.

(Bit-Depth/8)*(ImageWidth*ImageHeight)=ImageSize in Bytes

For example a 24-bit image at 1280x1024:

(24/3)*(1280*1024)

(24-bit/8) = 3
(1280x1024) = 1310720
3*1310720 = 3932160 bytes

Roughly 3.9mb

The screen resolution makes no difference when it comes to editing an image in photoshop or something like that. It retains all the information within the system or graphics ram anyway.

If you are talking about in game then the system RAM is only used to store the game data. All textures in use are stored in the gfx card RAM. Screen resolution again doesn't effect the size needed for textures. It depends on the texture settings within the game itself.
