On-Mobo video vs AGP cards for high-end 2D applications

Archived from groups: comp.sys.ibm.pc.hardware.video (More info?)

Is there a motherboard with on-board video that can do better the best
AGP video cards for 2D applications at, say 1900x1400 setting ? I'm
thinking of Photoshop.

I'd expect that direct memorory access can be faster than an 8x AGP
slot.

Thanks

I'm not sure what problem you think you're trying to solve. 1900x1400x32
bits is only about ten megabytes. I don't think you can buy a new video
board with that little RAM on it. The bandwidth of AGP 8X is such that you
could run a little under 200 frames per second at that resolution.

With photoshop the bottleneck is seldom anything having to do with the video
board. It's usually limited by CPU power and available RAM, although if
you're working with files larger than 1/5 or so of your available RAM then
disk performance can also become an issue. Photoshop can't address more
than 2 gig so if you have more RAM than that it might make sense to make
part of it a RAMDISK and put the Photoshop swap file, which is different
from the Windows swap file, on the RAMDISK.
