Answer 1

Igor Korobeinikov , he is right, he just mixed up the terminology a little.
"GPU Dedicated Memory" is the memory that resides directly on the graphics card itself.
"GPU shared memory" is the portion of your PC's RAM that the GPU can also use.
"GPU RAM" is the sum of allocated and total memory, i.e. the total amount of memory that is available to the GPU.
