PC Perspective have run a battery of benchmarks on the new Ryzen 5 2400G APU to see what effect memory speeds have on performance. We know that Ryzen is more sensitive to memory speeds than what we were used to, but what about when you throw a GPU into the mix that is utilizing the same memory pool. The difference in both synthetic and game benchmarks was nearly 10-15% for DDR4-2400 vs DDR4-3200. That is quite a bit of a performance impact. And the scaling seems to go up almost perfectly with the higher speed memory. As well it looks like if you are interested in a new Ryzen APU like I am, going dual channel memory is a must. Now if only memory prices weren't drunk right now. Thanks to @cageymaru for the story. For our testing, we are running the Ryzen 5 2400G at three different memory speeds, 2400 MHz, 2933 MHz, and 3200 MHz. While the maximum supported JEDEC memory standard for the R5 2400G is 2933, the memory provided by AMD for our processor review will support overclocking to 3200MHz just fine.
