| DietSoap said: 2gb for GPU Ram when even a launch title in the form of Killzone Shadowfall is already using 3.5gb as VRAM is... troubling moving forward, to say the least. Buying any card short of 4gb right now seems like suicide for the very near future. Waiting for 6gb on a non ridiculously priced card personally to air on the side of caution. |
This is false. Your GPU ram is only good if it can be utilized by the GPU itself. A GPU found in PS4, with 176 GB/s shared bandwidth with the CPU(more like 140 GB/s for GPU alone) and 1100-something cores can not push enough pixels to utilize 4 GB in a single frame. Killzone Shadowfas can utilize 3.5 GB of VRAM at some point thanks to texture caching or other elements it decides to store on the GPU, but it will never ever ever ever use 3.5 GB in a single frame, hence a 2 GB GPU would be plenty.
There are GPUs that are 2-3X more powerful than PS4 GPU (GTX 690 and 7990) which cant utilize 2 or 3 GB of RAM before the GPU itself becomes the framerate bottleneck. We're talking massive 5760x1200 resolutions here...
