Intel HD Graphics 520 gaming performance

I was wondering how much of a role RAM plays with Intel integrated graphics. I know having more RAM allows more RAM to be dedicated to the CPU which helps but I have a few questions.

In notebookcheck it shows "4gb dual channel" vastly outperforming single channel. Is this mainly because you will have 8gb of RAM total vs 4gb? (I'm assuming dual channel means 8gb but they don't elaborate). So based on this, with 8gb of RAM already, would I get a big increase by getting another 8gb stick to put in dual channel?

If the performance increase is just from increasing dedicated RAM for the graphics, couldn't I just increase the dedicated RAM without buying the extra stick (I found a few ways to do this online but from what I read you can only go up to 512mb dedicated RAM this way).

Also, would DDR4 RAM give a significant increase to gaming performance compared to DDR3 RAM?

BTW: The game I was referring to was Diablo III. For "Single channel 4gb" it had 21fps but with "Dual Channel 4gb" it was 30fps. I wasn't exactly sure how much total ram they meant for dual channel; 4gb or 2x4gb.

4gb dual channel doesnt mean 8gb, it is multiple stick of ram that run in dual channel, and it could probably be 2 stick of 2gb ram. number of ram channel varies depending on mobo and processor, but most were dual channel, but the enthusiast one were usually quad. more channel the ram running were usually better, but note that in some task, the performance difference were not always big and noticeable depending on what task it is. also remember that intel hd have limit of using shared ram, click this link to learn more https://www.intel.com/content/www/us/en/support/graphics-drivers/000020962.html . for sure using integrated graphics for gaming were not the best idea and dont expect you will get such an insanely good performance even if your intel hd have a lot of shared ram, especially heavy games that need such high vram wont run smoothly, because the clock speed of ram and gpu vram were much different, also several games dont support intel hd for gaming

Well in that case I guess dual channel makes a huge difference. I have a gaming desktop so I just want to play an occasional mmorpg or Diablo 3 on the laptop and don't care much about the gaming on it. I might as well get the most out of it though.
