The benefit to the processor is typically small. The benefit to the graphics can be significant, especially if you have a computer with several large display attached, as it is having to shuffle more information around.
I've noticed on the recent YT reviews of laptops with AMD Ryzen CPU's that the matched dual channel RAM graphics boost has been more significant than it used to be.
Historically around 10-15%, now it's more like 30%+. Mostly in gaming situations where FPS is important.
Gen 11 Intel CPU's are almost matching AMD for built in graphics performance these days - interesting times - especially with the Apple M1 move to ARM...
