Graphics cards have GDDR5 VRAM for running the graphics of games (managing the pixels, correct me if I'm mistaken).
What do APU's use? Do they have a decent amount of VRAM built onto them or do they just rely on your normal DRAM? I saw an article on anandtech (or it was a Linus vid...) on how having high frequency ram really affects an APU's fps performance in games. Is this because APU's rely on your normal DRAM?
