What Is Multithreaded Rendering?
What the term means
Multithreaded rendering means a render engine splits the workload across multiple processor cores simultaneously, rather than processing a scene sequentially on a single core, which significantly reduces the time needed to complete a render.
Most modern rendering software supports multithreading by default, since nearly all current processors have multiple cores available to use, making single-threaded rendering increasingly rare in practice.
How it affects performance in practice
The performance benefit of multithreaded rendering scales with the number of cores available, which is why processors with more cores are often prioritized for rendering workstations over processors optimized for single-core speed.
Not every part of a render benefits equally from multithreading, some calculations parallelize well across cores, while others remain limited by factors like memory bandwidth regardless of how many cores are available.
- Splits render workload across multiple processor cores at once
- Supported by default in nearly all modern rendering software
- Performance benefit scales with the number of available cores
- Not every calculation in a render parallelizes equally well
