When many designers want to buy a computer for rendering, they often see information about how many cores and threads are mentioned in the introduction of the processor (CPU), but they don't know what it means. In fact, the number of cores and threads of the CPU refers to the number of cores and threads of the CPU, which are two important indicators for measuring CPU performance . So how good is the CPU configuration for rendering? Let’s talk about the doorway today.
1. What is a CPU core?
The CPU core refers to the independent computing processing unit in the computer processor, which can execute different instructions at the same time, and their number is called the number of cores of the CPU. The higher the number of cores, the stronger the CPU's multitasking capabilities. For example, a quad-core CPU has four separate cores, and an octa-core CPU has eight separate cores.
2. What is a thread?
A thread refers to the smallest unit in a CPU that can run independently, and a thread is a separate execution sequence on the CPU. Each thread can execute an independent sequence of instructions concurrently. The number of threads refers to the number of threads that the CPU can handle simultaneously. Generally, a physical core provides at most two threads. The more threads you have, the more efficiently your computer will run. For example, if a CPU has 8 threads, when executing a task, 8 or 16 threads can be processed at the same time.
If you still don't understand, let me give a more vivid example here. The CPU can be imagined as a bank. The CPU core is equivalent to the teller, and the number of threads is equivalent to opening several windows. The more tellers and windows, the more businesses can be processed at the same time, and the speed will be faster.
3. Local rendering
Generally, the performance of local computers is often insufficient, and the number of cores and threads is very limited. It is barely enough when rendering small images, but it is not enough when it comes to large images . Moreover, it cannot handle multiple rendering tasks locally at the same time , and it will be stretched when encountering difficult or large-volume tasks.
4. Creative Cloud Rendering
When there are many and urgent rendering tasks, the local computer is often too late, so you can choose cloud rendering. Creative Cloud Rendering can submit local tasks to the cloud server with one click, and use high-performance computer clusters in the cloud for rendering calculations, which greatly improves the rendering speed. For example, "The Wandering Earth 2" has more than 2,000 special effects materials, and the content volume is more than twice that of the first one. If a single computer is used to render, it takes 3,114,000 hours, which is equivalent to a server working for 355 years! However, through the rendering of the blue sea creative cloud rendering farm, the rendering time is less than a month, which ensures the efficient and smooth completion of the project .
At present, Blue Ocean Creative Cloud Rendering provides film and television animation rendering and rendering rendering services . Effect picture rendering Users can freely choose 32-thread, 320-thread or even 2048-thread machines for cloud rendering through the creative cloud rendering plug-in, which greatly improves the drawing efficiency.
Of course, you will find that the same 320 threads have two different rendering modes: block rendering and distributed rendering . What is the difference between them, and how should users choose? If you want to know, you can pay attention to the next issue or consult me in the background!
