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 from Patriot. By doing so, the game benchmarks reveal where the limitations lay in a top of the line Intel computer for 2023. For both memory kits, XMP is loaded and all sub-timings are based on the individual XMP profile and motherboard. 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): Patriot Viper Xtreme 5 RGB DDR5-8000 PVXR532G80C38K (38-48-48-84)
Memory (1): Patriot Viper Venom DDR5-7200 PVV532G720C34K (34-42-42-84)




Comparing both these memory kits with low graphical settings shows a surprising lack of performance increase for Cyberpunk 2077. This just one of many games, but as covered in the testing methodology section, system memory is only one factor for frame generation.




Increase the graphical settings, and in this example, we are still GPU bound from the low settings and waiting on the graphics for the next frame calculations.




Raising the game's resolution to 4K and Cyberpunk 2077 is still in the same place as before. It is completely GPU bound, leaving the CPU often waiting on the graphics card to finish each calculation. With a margin of error of 5%, these two memory kits are indistinguishable at this resolution using a RTX 4090.
