Single Rank vs Dual Rank comparison
+ 1600-2400mhz comparison
In this post we want you to show, why Dual Ranked RAM (do not mix it up with Single and Dual channel) is mandatory for APUs (Example A10 7850k).
We run minimum 5 tests with every game and compared the average FPS (mid fps of 5 runs)

|APU||DDR3 SR 1600||DDR3 SR 1866||DDR3 SR 2133||DDR3 SR 2400||DDR3 DR 1600||DDR3 DR 1866||DDR3 DR 2133||DDR3 DR 2400|

You can clearly see that with a Dual Rank RAM (DR) you have a 5,7% (minimum) to 15,9% (maximum) improvement on your Frames. Since DR memory is most often not more expensive than SR (Single Rank), it is wise to choose a DR memory in 100% of times.
We have a comparison of 2133mhz DDR4 and 3200mhz DDR4 with a Ryzen 5 2400G APU.
Comparison between 2133 and 3200 mhz
The difference is a total score of 2406 to 3426. That is a whooping +42.4 % increase in performance.
Games wont benefit this much from it but we are are testing it at the moment.
