RAM Latency benchmarks for GPU Performance (alien.top)

Hi all,

I am trying to find out how much performance is lost when using CL46 instead of CL40 RAM in the AMD Framework 13 7840u.

I have already looked through other posts on this subreddit in search for information but not found any extensive testing results.

Summary

Question: Will the difference from CL46 to CL40 be noticeable when gaming?

I am trying to deciding between getting 96GB of CL46 RAM that would better support my workflow...
Crucial 96GB Kit (2x48GB) DDR5 5600MHz CT2K48G56C46S5

...or 64GB of CL40 RAM that might perform better in video games.

#Use case: I am a software developer that requires multiple VMs for testing, I currently use around 32GB of RAM before opening any VMs.

I am also a gamer and want to use the system for light gaming, CS2, Diablo 4, Titanfall 2, Overwatch etc. and understand the graphics performance is very much affected by RAM Latency.

Going to be traveling for the next year and need to strike a compromise between the 2.
After that year I am going to have a desk with a eGPU (where I would probably benefit more from the increased amount of RAM)

Thoughts and views are appreciated, while tech-y I am unfamiliar with hardware at such a low level

How often will you use more the 64gb of ram? The performance penalty when you do will be much more then the performance gained from faster memory. It's also easier to turn down game settings, so I would definetly tend towards more RAM.
