Does Memory Speed Affect Gaming Performance; An Intel Question

Memory V.S Gaming Testing:

Let me do a 180 here and refresh my train of thought. The results from the benchmarks I have done up to this point appear to indicate that DDR4 memory wasn't much of a bottleneck with resolutions up to 1440p. A resolution of 1920 x 1080 saw a slight change from minimum and maximum, but the overall average was within a 3% margin of error across all the games. Now it is time to assess how DDR3 performs in the same games. It is important to keep in mind that this is a completely different system other than the SSD, monitor and video card. This can also give you an insight of what to expect if upgrading is in your budget this year. I already spent my tax returns so it's unlikely I will be getting any more new toys this year.

Metro 2033: Redux:

Testing with DDR3 only gave me a difference of about 1 FPS, so if you already have a blazing fast DDR3 setup, you might want to just invest in a new video card rather than a whole new computer. However, this is only one game at a single resolution. I think a comparison article will be next on my to-do list. Moving on to DDR3 it is clearly a massive swing in FPS across all categories from DDR3 1333 to DDR3 2400. This game is hungry for bandwidth. I want to see what a GTX 1080 Ti would look like, but that will have to wait until next time.

Warhammer 40,000: Dawn of War III:

Ouch! It keeps happening. If Dawn of War 3 is your new favorite game, I suggest getting some faster memory if you play at 1920 x 1080. Once again it is clear DDR3 can hold back certain games using slower memory. It seems to me from the charts that it is a clean sweep, DDR3 2400 just crushes 1333 in this particular game.

Tom Clancy's Ghost Recon: Wildlands:

When looking at the chart for GR:W, you might think that I have typed the numbers in wrong, but that is not the case. This is very strange to me but it looks like memory isn't so much of a bottleneck compared to the video card. If that trend continued, I bet if I turned down a few settings it would be more apparent that DDR3 has a few constraints. However, this is why I chose to run them all with the same settings, it gives a bigger picture of what is in play here. Memory speed for GR:W using the maximum settings is not a major factor.
