Dual channel RAM

[ricardomartins831]

Hi,
What type of games benefit more from dual channel?

none in particular, everything calls upon memory, all of the time.

What's the real story behind your question?

i have an apu a10 9700 and i heard that it benefits a lot from dual channel
since i have a low pc every fps that i can gain it will worthy
also i heard that cpu intensive titles tend to benefit more from dual channel is that true'
btw thx for the answer

you have a slightly odd scenario.

Because you are using an APU and (possibly) no discrete GPU, it uses main memory and not Vram.

Vram is quicker than ram, and closer to the GPU, i.e. on the same card. In these cases the memory speed therefore become really important.

dual channel itself has only been shown to be about 5% of an improvement, faster memory in dual channel would be better, get as fast as you can in dual.

btw would it make a big difference with a dedicated GPU? cuz i forgot to mention that i have a rx 550...

On Ryzen it does, but certainly a lesser difference
