2048 * 1536 * (32 bits per pixel) = 12 megabytes
to store the display. 24 megabytes if it needs to double-buffer.
- rbritton 16y agoThere's actually quite a bit of overhead at the CG* and Core Animation layers of the SDK that bump that up substantially. In the current iPad, it takes just a bit over 10 MB to store the image data for 1024x768 and have the necessary system stuff loaded into memory. I suspect that extra bit would not increase substantially on a 2x screen, but I'm sure it would some.
- jckarter 16y agoThat's just for the framebuffer. All the intermediate textures flying around will need four times the memory too, and could easily eat up several hundred megabytes.
