What is the importance of video rendering, GPU or CPU? Video rendering is different from CG rendering in that they are completely different rendering methods.
Video rendering, in general terms, is to combine the various models, effects, or animations that were made in the early stage in the post-production software. In these processes, complex effects and effects are inevitably involved. It is difficult to achieve real-time display with the current computer computing power, so after editing the graphic image, the final effect we need is output by adjusting and modifying, that is, video rendering.
Video rendering requirements for graphics cards and CPU.
For professional design work, 3D modeling / video rendering, general CPU multi-core and multi-thread parallel processing is very important, and requires a faster and larger cache of the CPU to temporarily store a large amount of computing data, this time CPU computing power requirements are very high.
Therefore, the general professional work computer, the CPU requirements are relatively high, the general advanced architecture, multi-core, large cache high-end CPU can better meet the demand.
In video rendering, the graphics card is more of an acceleration, 3D effects will rely on graphics cards.
Take Adobe Premiere video editing software as an example. This professional software relies more on CPU multi-threading performance. The more cores and threads, the faster the video processing speed will be. In some video size compression and format conversion, transfer a certain amount of GPU graphics card resources, but the mobility is limited, ordinary low-end GPU graphics cards can meet the demand.
Of course, it is not that professional graphics, GPU graphics are not important, general 3D modeling is more dependent on GPU graphics than CPU.
In general, the modeling of 3D software depends on the CPU. Regarding the professional design, it depends on the CPU or GPU. The main focus is on the scene and the software. Generally, the CPU is mainly clipped, the GPU is accelerated, and the 3D special effects production depends on the GPU. CPUs and GPUs are important for professionally designed computers.
In the rendering of video compression, the higher the GPU, the lower the GPU occupancy rate. At present, it is like Adobe Premiere video editing software, mainly based on CPU work, GPU is supplemented by such a state, and as long as Low-end GPU graphics can be very demanding.
