![]() ![]() I had a fair few expectations from the figures, but the results I got were a little less than expected. Something I need to make clear before you read on, my memory bandwidth usage figures (GB/s) are not 100% accurate. They have been estimated and extrapolated using performance percentages of the benchmark figures I’ve got, as such, most of this article will be relying largely on those estimations. NVidia has said themselves that Bus usage is wholly inaccurate, and most of us are aware that Memory Controller Load (%) cannot represent the exact bandwidth usage (GB/s) with total precision. All loads are different.Īll of the following benchmarks were run 4 times for each game on each resolution for accuracy. Every preset is set to High where Very High is unavailable. The only graphical alteration to my video settings was turning off VSync and Motion Blur. I’ve chosen to run with 4 games which I felt represented a fair array of game types. For CPU orientated, I’ve run with Insurgency. This is Source engine based, highly CPU intensive, and should cover most games running that sort of requirement. It has a reasonable VRAM requirement, but is overall quite light on general GPU usage, so it should stress the memory somewhat. To represent the independent games, while also holding a high VRAM requirement, I’ve run with Starpoint Gemini II. ![]() This game has massive VRAM requirements, and is quite a GPU heavy game. I’ve chosen two other games for the AAA area, one very generalised game, and one that boasted massive 4GB VRAM requirements for general high res play. Far Cry 4 felt like a good representative for the AAA genre that has balance in both general performance of the CPU, GPU, and moderate VRAM requirements. Middle Earth: Shadow of Mordor was my choice for the AAA genre to slaughter my VRAM and hopefully put my GPU memory controller and VRAM to the test. Shadow of Mordor peaks within percentile points of the available bandwidth on a 770 (224GB/s), but all other games remain below to 200GB/s mark.
