How does RAM quantity effect iGPU's?

[Top-Hat Meerkat]

If the iGPU only has 1.5GGB of RAM dedicated to it, will a laptop with an iGPU with 8GB of dedicated RAM be noticeably faster when playing games?

Nope, your still using a igpu.

 

For vram, you only need a certian amount, any more won't help

Depends - iGPUs benefit from faster RAM, not more RAM in most cases.

not really "faster" as such, but it really depends on what games you are going to play

Well in theory... More RAM is always better.  But the truth is most iGPU's (even AMD's 10x more powerful APU's will suffer from this) don't have enough horsepower to be able to process 8GB worth of textures quick enough to produce even 30fps.

 

Honestly, I'd say that anything more than 1GB of VRAM on Intel's iGPU is wasted and 2GB on AMD's is.  Its better to focus on faster RAM than more RAM, after the 8GB mark.  (But just to be clear, more is ALWAYS better)

An iGPU has no dedicated VRAM, so things that would go into VRAM on a discrete card have to leverage your system memory instead. So your memory bandwidth certainly matters, because that will directly affect the ability to swap game data into/out of that RAM.

 

The quantity of RAM isn't such a big concern, because the video settings appropriate for an iGPU tend to require minimal amounts of memory.
