Question What aspect of memmory is more important

Read or write?

Probably depends upon what you are doing, I assume the question is about storage and not ram.

Read or write?

I would think that read and copy performance are more important than write performance for gaming because the ram typically reads data from storage and copies it into VRAM if I'm not mistaken.

Also the CPU uses ram to both read, copy and write data during games but mostly read and copy.

ram for gaming

I don’t think there is enough difference in either case between the fastest and slowest to matter.
Memory is pretty simple for gaming the more the better, the faster the better in that order. Time and time again it is shown more memory is better than fast memory. I suspect read/write would be the same.

ram for gaming

If you are asking about how to select the best RAM for gaming, the ones with the lower timings are usually better when speeds are same. Higher speed RAM with slightly worse timing may make up the difference with higher bandwidth once the data starts copying. For DDR4, you want something like DDR4-3200 CL14 or DDR4-3600 CL16 or DDR4-3800 CL18. For DDR5, Ryzen 7000 likes DDR5-6000 CL30 and Alder Lake/Raptor Lake give better performance with DDR5-6400 CL32. You can buy DDR5-7200 CL34 too, if you have loads of cash to burn.

 

[The red spirit]

Since RAM serves CPU, you need both reads and writes. RAM is used only after caches, but for whatever task you do, inputs to CPU are reads, meanwhile CPU outputs are writes. It's not even task specific, but more instruction specific. You really shouldn't worry about that for gaming, just buy whatever has highest clocks and lowest latency and is supported by board and it's going to be fine. BTW clocks>latency, because clocks decide how long each cycle takes, meanwhile latency only reduces latency cycle number, which is usually much smaller than task itself.

I agree with the above with one exception.
Assuming you have a budget go with the lowest latency memory you can afford HOWEVER if the choice is less memory that is lower latency vs more memory as in 16GB of cas 14 vs 32GB of cas 18
take the 32GB, as I said above lower latency is better but only by a few percent. Real world difference is not noticeable. Larger pool of memory keeps your machine a viable gaming machine for a longer period of time
