Capacity will really only have a significant impact upgrading from 8GB or less, and speed will yield a modest spike in performance in specific instances but never anything approaching the increases you're likely to see upgrading performance parts like the CPU or GPU. On the whole, does RAM speed and capacity really matter for gaming? The answer is a qualified yes. While I don't have enough data to state concretely that AMD systems broadly benefit more from speedier RAM (something I may explore in a future feature), that is certainly the case in this particular processor comparison. And I need to note that I can't rule out the choice of motherboard, as BIOS and firmware could also be impacting the results. According to our tests, a Ryzen 7 2700X equipped system benefits significantly more than one with a Core i9-9700K. There's also a significant difference in results between the AMD and Intel test beds. And if you're looking for an inexpensive way to boost performance in a rig with an aging GPU, adding a couple of more RAM sticks is a reasonable stopgap. To future proof your machine, pushing up to 32GB of RAM is looking more and more reasonable, particularly with memory prices dipping. 16GB is still enough in this scenario, but with system memory allocation running up to 12 or 13GB in some triple-A titles that may not be the case for very long.
We've definitely hit a point where 8GB of RAM is presenting a performance bottleneck, even in a system with a GPU equipped with a spacious 11GB of VRAM. Frequency resultsĪll of this testing revealed some definite trends, some obvious, some quite interesting. Any improvements fell into the margin of error except in the case of Metro Exodus, which yielded a 5 fps or 9 percent improvement from 16GB to 64GB in the Ryzen 7 machine and 4 fps or 6 percent in the Intel rig. On the other hand, performance increases from 16GB to 32 GB, all the way up to 64GB, were fairly flat. Significant, if not mind blowing, and those performance gains were also reflected in the 97 percentile scores. Between 8GB and 16GB capacity in the AMD system we saw a 9 percent performance increase in Shadow of the Tomb Raider, 14 percent in Total War, and 10 percent in Metro, while the Intel machine showed improvements of 5 percent in Shadow of the Tomb Raider and Total War, and 7 percent in Metro. While the results here certainly showcase very playable frame rates, especially in Shadow of the Tomb Raider and Total War: Warhammer 2, in lesser systems those numbers would dip into uncomfortable ranges. In 2019, 8GB is not enough RAM for a lot of triple-A titles, even with a GPU loaded with VRAM doing a lot of the heavy lifting.
Our capacity results showed a pretty steady, fairly obvious trend.
