Does Memory Speed Affect Gaming Performance; An Intel Question


Memory V.S Gaming Testing: 

Kicking things off with DDR4, the resolution of 1920 x 1080 is very common for gaming and a good practical testing resolution. These are the results I have gathered using the in-game benchmarks and are reproducible numbers as I ran each benchmark more than once to double check when things looked odd. This isn't a scientific paper, but the numbers generated are not created in a fast and loose fashion.


Metro 2033: Redux: This is a first-person shooter survival horror video game that is extremely graphically intense with NVIDIA PhysX and the newest graphic options. If you haven't played this game, It is a must for any gamer! Originally introduced in 2010, it was re-released in 2014 under the Redux name which included all the graphic engine upgrades found in the sequel Last Light with a few extras bits on the side.

Metro 2033: Redux has been named the modern day Crysis by many because of how graphically and processor intense the game is. In fact, if I enabled SMAA (Subpixel Morphological Anti-Aliasing) then all bets were off for a consistent result because of how resource intense this game is. At least under DDR4 the average frame rate is within a 3% margin of error.


This is when things get a little crazy. I had a lot of issues getting any resolution or memory speed to give a consistent minimal frame rate. I almost didn't include this, but here it is. However, the maximum frame rate was more predictable and constant for each benchmark run so I'm confident in these results.


Warhammer 40,000: Dawn of War III: This game is an RTS from Relic Entertainment, the company behind the Company of Heroes franchise. It was released in 2017 and makes quick work of any gaming computer because of heavy CPU and GPU tasks. Of course I didn't go easy and benchmarked it using the highest settings.

With the latest patch and NVIDIA drivers, Dawn of War 3 was more within the realm of believable. I had a lot of issues getting above 60 FPS until the newest patch came out at the end of March 2017. That being said, with a 3% margin of error, an argument can be made that there is little difference for the average frame rate. However, these results are very consistent so I think it's safe to say that the lowest rated memory will be slower and it seems to continue to climb until something becomes a bottleneck down the line.


Tom Clancy's Ghost Recon: Wildlands: This is a sandbox open-world style shooter based in the Ghost Recon world. If you like the idea of teaming up with friends to take down some bad guys, then this might be for you. Besides being a sandbox, go anywhere, complete mission your way style game, you can play the whole game in Co-Op. GR:W is also a 2017 release, which is even more of a reason to benchmark it! This game is just crushing it on the current generation of video cards, but it does look beautiful!

The average and max FPS is still within the 3% range. Looking at the charts, this game at 1920 x 1080 has a 99% GPU load and around 30% for the CPU. It is clearly a video card bottleneck and faster memory will not make a difference under these conditions. Not many benchmarks gives this extra bit of data and I wish more did.
