Gaming Performance Benchmarks: DDR5-4800
To show the performance of DDR5 memory in different configurations, we've opted for a more selective and short-form selection of benchmarks from our test suite. This includes Civilization VI, Grand Theft Auto V, and Strange Brigade (DirectX 12).
All of the tests were run with all of the memory at default (JEDEC) settings, which means DDR5-4800 CL40, regardless of the configuration, e.g, 2x16, 2x32, and 4x16 GB.
Originally penned by Sid Meier and his team, the Civilization series of turn-based strategy games are a cult classic, and many an excuse for an all-nighter trying to get Gandhi to declare war on you due to an integer underflow. Truth be told I never actually played the first version, but I have played every edition from the second to the sixth, including the fourth as voiced by the late Leonard Nimoy, and it is a game that is easy to pick up, but hard to master.
Benchmarking Civilization has always been somewhat of an oxymoron – for a turn based strategy game, the frame rate is not necessarily the important thing here and even in the right mood, something as low as 5 frames per second can be enough. With Civilization 6 however, Firaxis went hardcore on visual fidelity, trying to pull you into the game. As a result, Civilization can taxing on graphics and CPUs as we crank up the details, especially in DirectX 12.
Despite games traditionally being a GPU bottleneck instead of a CPU/memory bottleneck, in our Civ VI testing we do find some small but statistically meaningful differences in our results. The 2 x 32 GB kits were the best of the bunch, with the Samsung 2 x 16 GB kit running slightly slower. The Samsung 4 x 16 GB kit however performed a couple of frames per second slower than the rest, coming in a bit over 3% slower than the 2 x 32 GB Samsung kit.
Grand Theft Auto V
The highly anticipated iteration of the Grand Theft Auto franchise hit the shelves on April 14th 2015, with both AMD and NVIDIA to help optimize the title. At this point GTA V is super old, but still super useful as a benchmark – it is a complicated test with many features that modern titles today still struggle with. With rumors of a GTA 6 on the horizon, I hope Rockstar make that benchmark as easy to use as this one is.
GTA doesn’t provide graphical presets, but opens up the options to users and extends the boundaries by pushing even the hardest systems to the limit using Rockstar’s Advanced Game Engine under DirectX 11. Whether the user is flying high in the mountains with long draw distances or dealing with assorted trash in the city, when cranked up to maximum it creates stunning visuals but hard work for both the CPU and the GPU.
The in-game benchmark consists of five scenarios: four short panning shots with varying lighting and weather effects, and a fifth action sequence that lasts around 90 seconds. We use only the final part of the benchmark, which combines a flight scene in a jet followed by an inner city drive-by through several intersections followed by ramming a tanker that explodes, causing other cars to explode as well. This is a mix of distance rendering followed by a detailed near-rendering action sequence, and the title thankfully spits out frame time data. The benchmark can also be called from the command line, making it very easy to use.
Using Grand Theft Auto V's built-in benchmark at 1080p, all of the JEDEC DDR5-4800B kits performed competitively with each other – albeit with a higher degree of variability than usual due to the nature of the game. Still, in our 4K testing, we see that Samsung 4 x 16 GB kit once again brings up the rear, this time falling behind the 2 x 32 GB kit by 7%.
Strange Brigade (DX12)
Strange Brigade is based in 1903’s Egypt and follows a story which is very similar to that of the Mummy film franchise. This particular third-person shooter is developed by Rebellion Developments which is more widely known for games such as the Sniper Elite and Alien vs Predator series. The game follows the hunt for Seteki the Witch Queen who has arisen once again and the only ‘troop’ who can ultimately stop her. Gameplay is cooperative-centric with a wide variety of different levels and many puzzles which need solving by the British colonial Secret Service agents sent to put an end to her reign of barbaric and brutality.
The game supports both the DirectX 12 and Vulkan APIs and houses its own built-in benchmark which offers various options up for customization including textures, anti-aliasing, reflections, draw distance and even allows users to enable or disable motion blur, ambient occlusion and tessellation among others. AMD has boasted previously that Strange Brigade is part of its Vulkan API implementation offering scalability for AMD multi-graphics card configurations. For our testing, we use the DirectX 12 benchmark.
There wasn't much difference in our testing between the 2 x 32 GB kits in our Strange Brigade Direct X12 testing. At 4K, the Samsung 4 x 16 GB once again performed slightly slower than the rest, although Samsung's 2 x 16 GB configuration performed in-line with the 2 x 32 GB kits.

ralritt - Thursday, April 7, 2022 - linkAll of the charts are labeled as DDR4-4800.
Medikit - Thursday, April 7, 2022 - linkI was going to mention this as well. Guess we are still getting used to saying/writing DDR5.
Ryan Smith - Thursday, April 7, 2022 - linkIndeed we are. Thanks for spotting that one!
flashmozzg - Thursday, April 7, 2022 - linkSame with test setup.
porina - Thursday, April 7, 2022 - linkInteresting results. For DDR4 I found [2DPC 1R = 1DPC 2R] > 1DPC 1R, at same speed/timings. This was handy to use multiple small modules to get the higher performance, than the lottery of ensuring 2R modules since the trend over time is to lower rank at a given capacity. Life is going to be interesting when I decide to go DDR5!
Gavin Bonshor - Thursday, April 7, 2022 - linkI will change this as soon as I get WiFi on my laptop. Thanks for the spot
lschiedel - Thursday, April 7, 2022 - linkNow please follow up with a laptop test. What speed penalty is there on a 8gb soldered + 8gb sodimm with swapping the 8gb sodimm for a 32gb sodimm? And how does it compare with a model that comes standard with 16gb + 16gb?
LordRahl72 - Thursday, April 7, 2022 - link+1 to this. I am thinking of adding a 32GB stick to my Zephyous m16 but wondering if there would be any performance hit or not.
lschiedel - Thursday, April 7, 2022 - linki've already upgraded my m16.
maybe we both should run the tests and compare.
it would be nice if we could try a benchmark that can to test the first 16gb or all ram.
deil - Monday, April 11, 2022 - link+1 as well I am about to get one, so this info would be great.
