4k forza horizon 4 backgrounds2/24/2023 ![]() ![]() ![]() The RTX 4090 is a monster physically, but it’s also a monster when it comes to 4K gaming performance. I kept Resizeable BAR turned on throughout testing, or in the case of AMD GPUs, Smart Access Memory. All of my tests were done with a Ryzen 9 7950X and 32GB of DDR5-6000 memory on an open-air test bench. AMD’s GPUs, which don’t have CUDA, aren’t even close. Blender is accelerated by Nvidia’s CUDA cores, and the RTX 4090 seems particularly optimized for these types of workloads, with it putting up more than double the score of the RTX 3090 and RTX 3090 Ti in the Monster and Junkshop scenes, and just under double in the Classroom scene. I also tested Blender to gauge some content creation tasks with the RTX 4090, and the improvements are astounding. In fact, my results from real games are actually a little higher than what this synthetic benchmark suggests, at least outside of ray tracing. ![]() In the case of the RTX 4090, though, 3DMark shows the scaling well. It’s important to note that 3DMark isn’t the best way to judge performance, as it factors in your CPU much more than most games do (especially at 4K). Port Royal and Time Spy from 3D Mark show how Nvidia’s latest flagship scales well, showing a 58% gain over the RTX 3090 Ti in Time Spy, as well as a 102% increase over the RTX 3090 in Port Royal. Synthetic and renderingīefore getting into the full benchmark suite, let’s take a high-level look at performance. Clock speeds remain high, but the specs of the RTX 40-series family right now suggest that the boosted core count won’t be a major selling point, at least for gaming. Down the stack, the 16GB RTX 4080 has a little more than half of the cores as the RTX 4090, while the 12GB RTX 4080 has even less. It’s hard to say how much those extra cores matter, especially for gaming. ![]()
