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 retail memory kits. By doing so, the game benchmarks reveal where the limitations lay in a top of the line Intel computer for 2024. For both memory kits, XMP is loaded and all sub-timings are based on the individual XMP profile. These are not adjusted further.

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): Acer Predator Hermes DDR5-6800 32 GB BL.9BWWR.401 (32-45-45-108)
Memory (1): DDR5-6000 32 GB (30-40-40-77)




The first game to be tested is Forza Horizon 5. Generally speaking, Intel is less sensitive to memory latency in comparison to AMD CPUs and benefits the most from higher-frequency memory instead. Comparing two low-latency oriented memory kits, we can see the frame gap between the two is minor. This amount falls under a margin of error, leaving both memory kits on equal footing for Forza Horizon 5.




As we raise the graphical settings, this gap is still margin of error.




Lastly, at 4K, nothing has changed between the two besides an overall lower frame rate.
