Shared vs Dedicated graphics memory for large photo editing

by GPHisto / January 31, 2013 9:47 PM PST

I'm about to buy a new laptop for processing some large images (~2-3GB each) and am unsure which route to go for graphics memory - shared or dedicated.

I understand the usual caveats about the different memory types (i.e. shared is better for battery life and fine for everyday use; dedicated is typically better for graphics intensive gaming). I will be doing no gaming of any kind, just processing images 2-3GB in size in photoshop and ArcGIS. The largest GPU I can find with dedicated memory in my price range is 2GB, which sounds pretty good but I am unsure how this will handle images of the such size. I'm planning on upgrading the laptop to 16GB of RAM, so would having shared memory be better, since there would so much memory available?

Any insight would be greatly appreciated.

Barely any effect.

I've seen both and can't see much if any difference. There are folk that believe there is a difference and I did write there is. Just not enough for me to worry about.

What you never mentioned is if the display has a good gamut or is color calibrated.

You need a discrete video chip

Actually, the minimum Windows hardware requirements ( for Photoshop CS6 call for an OpenGL-2.0 capable system and 256 MB (512 MB recommended) of VRAM. The current version of Photoshop actually offloads a great deal of processing to the video card. I would definitely not get a machine without a dedicated video card if I was intending to run Photoshop.
