Can somebody explain to me what dedicated vs shared memory is? I thought GPU should have 6gb onboard? What does shared mean? Tell me something so I can learn. biggrin.gif

Thanks!

Thanks!

Dedicated is the amount of memory your graphics card has, in this case your Radeon HD79X0 should only have 3GB (unless you bought the 6GB Sapphrie version).

Shared System memory is based on how much DRAM you have installed.

When you run out of dedicated memory (gpu) your system will start using your ram (pc). The ddr3 memory is much slower at both the speed it runs and the speed your gpu can access it. You'll know it's happening by a huge drop in fps and stuttering.
