Frametime Analysis

We present a more in-depth analysis than just average FPS to show how the framerate changes over time, which helps highlight FPS drops. Minimum FPS at both the 95th and 99th percentile are reported in these charts, too. A second chart, a histogram, shows shape and spread for the frametime data—how tightly grouped the measurements are. The "IQR" result is called "Interquartile Range," which is an outlier-resistant statistical value that tells us the range in the middle of the frametime distribution.

In the following charts, we are comparing two Corsair retail memory kits. The primary and sub-timings are based on the individual XMP profiles and are not adjusted further. By doing so, these charts represent a direct comparison between Corsair Vengeance 7200 MT/s 32 GB and Corsair Dominator Titanium 7200 MT/s 48 GB.

Tests are conducted with the following components:
CPU: Intel Core i9-13900K (Locked P-core 5.5 GHz, E-cores 4.3 GHz)
GPU: PNY GeForce RTX 4090 XLR8 VERTO
Memory (1): CORSAIR Vengeance RGB DDR5-7200 (32 GB) CMH32GX5M2X7200C34 (34-44-44-96)
Memory (2): Corsair Dominator Titanium DDR5-7200 (48 GB) CMP48GX5M2X7200C36 (36-46-46-116)




Running the game benchmarks on Lower graphical settings places a higher load on the CPU due to shorter rendering times per frame from the Graphics card, thus more frames in total. This can help illustrate how primary and secondary timings may impact the framerate in games. However, not all games are impacted by the amount of memory frequency and timings.




Bumping up the graphical settings and the frame-rate decreases. Interestingly, in Red Dead Redemption 2, higher settings adds more CPU calculations, which separates the two memory kits in this graph, as the game is not 100% GPU-bound yet.




Pushing into 4K resolution and Red Dead Redemption 2 becomes completely GPU bound, leaving the CPU waiting on the graphics card to finish each calculation. With a margin of error of 3%, these two memory kits are indistinguishable at this resolution using an RTX 4090.
