As always, an RTX 3090 Founders Edition from Nvidia is used for the gaming tests, with maximized temperature and power consumption limits, for the lowest possible GPU bottleneck. The performance data is recorded with Nvidia Frameview 1.2, based on the open-source software Presentmon. Since Cyberpunk has lost its significance in past tests and also its relevance among many gamers, there is a new game title instead. Assetto Corsa Competizione is a racing simulation that places high value on accurate physics, and in multiplayer with up to 30 players, it sets high standards even for the fastest CPUs. The other two titles Shadow of the Tomb Raider and CS:GO remain with us.

Gaming QHD

As we all know, it always depends heavily on the specific game title, whether you can actually measure performane gains due to fast DDR5 memory, or if maybe DDR4 with its lower latency might still be the better choice. At least with an RTX 3090 we are almost always in the GPU bottleneck anyway. Therefore the differences often only make up few percentage points with realistic resolutions and detail settings.

Assetto Corsa Competizione - FPS - 1440p

Counter Strike Global Offensive - FPS - 1440p

Shadow of the Tomb Raider - FPS - 1440p

Assetto Corsa Competizione is one of the few titles that still favors DDR4, even at relatively high resolutions. Here the Corsair kit with 7000 Mbps overclock can barely squeeze by into first place, while the differences overall only make up a few FPS.

In CSGO the picture is very similar, but here DDR4 was left behind earlier with more DDR5 kits being measurably faster. An extreme case is Shadow of the Tomb Raider, where DDR4 with its lower bandwidth suffers extremely in QHD. Here the DDR5-7000 config can deliver 13 % more average FPS in comparison.

Assetto Corsa Competizione - FrameTimeVariance - 1440p

Counter Strike Global Offensive - FrameTimeVariance - 1440p

Shadow of the Tomb Raider - FrameTimeVariance - 1440p

The frame time variances mostly mirror the results from the FPS diagrams in colorful form. The only bigger excursions into the red exist in CSSO, but here the game engine seemingly often gets a hickup seemingly randomly.

Gaming FHD

Assetto Corsa Competizione - FPS - 1080p

Counter Strike Global Offensive - FPS - 1080p

Shadow of the Tomb Raider - FPS - 1080p

In 1080p we see big differences in ACC with the fps numbers. Even if the DDR4 config is still in second place, behind it big gaps appear. 18 % more FPS on Average and 20 % more with the 1 % lows the fastest DDR5 memory can move ahead of the 4800 JEDEC config.

Similarly in other titles we see the Corsair DDR5-6600 kit always at the top of the ranking, especially with manual optimizations. However, general statements regarding the performance scaling of memory in games are difficult, as really every game title behaves differently.

Assetto Corsa Competizione - FrameTimeVariance - 1080p

Counter Strike Global Offensive - FrameTimeVariance - 1080p

Shadow of the Tomb Raider - FrameTimeVariance - 1080p

Looking at the Frame Time Variances in Full HD we see again a mirror image of the average FPS.
