Memory Performance: 16GB DDR3-1333 to DDR3-2400 on Ivy Bridge IGP with G.Skillby Ian Cutress on October 18, 2012 12:00 PM EST
Metro2033 is a DX11 benchmark that challenges every system that tries to run it at any high-end settings. Developed by 4A Games and released in March 2010, we use the inbuilt DirectX 11 Frontline benchmark to test the hardware at 1920x1080 with full graphical settings. Results are given as the average frame rate from 4 runs.
While comparing graphical results in the 5 FPS range may not seem appropriate, it taxes the system to its fullest, exposing whether at this high end memory actually makes a difference or if we are weighing on computation. What we do see is a gradual increase in frame rate with each kit, up to 10% difference between the top end and the bottom kit. The pivotal point of increase is from 1333 to 1866 – beyond 1866 our increases are smaller despite the increased cost of those kits.
Civilization V is a strategy video game that utilizes a significant number of the latest GPU features and software advances. Using the in-game benchmark, we run Civilization V at 1920x1080 with full graphical settings, similar to Ryan in his GPU testing functionality. Results reported by the benchmark are the total number of frames in sixty seconds, which we normalize to frames per second.
In comparison to Metro2033, Civilization V does not merit a large % increase with memory kit, moving from 3% to 6.7% up the memory kits. Again we do this test with all the eye candy enabled to really stress the CPU and IGP as much as we can to find out where faster memory will help.
Dirt 3 is a rallying video game and the third in the Dirt series of the Colin McRae Rally series, developed and published by Codemasters. Using the in game benchmark, Dirt 3 is run at 1920x1080 with Ultra Low graphical settings. Results are reported as the average frame rate across four runs.
In contrast to our previous tests, this one we run at 1080p with ultra-low graphical settings. This allows for more applicable frame rates, where the focus will be on processing pixels rather than post-processing with effects. In previous testing on the motherboard side, we have seen that Dirt3 seems to love every form of speed increase possible – CPU speed, GPU speed, and as we can see here, memory speed. Almost every upgrade to the system will give a better frame rate. Moving from 1333 to 1600 gives us almost a 10% FPS increase, whereas 1333 to 1866 gives just under 15%. We peak at 15% with the 2133 kit, but this reinforces the idea that choosing a 1600 C9 kit over a 1333 C9 kit is a no brainer for the price difference. Choosing that 1866 C9 kit looks like a good idea, but the 2133 C9 kit is reaching the law of diminishing returns.
