![]() CPUs with up to 8 cores run at a clocks speeds up to 4.5GHz. Unlike the Tier One workstation manufacturers some of the smaller specialist firms overclock their Core i7 chips. These include the Intel Core i5 and Core i7 (which are also found in desktop PCs) as well as the more workstation-focused Intel Xeon. Single processor workstations come with a massive choice of CPUs from 2 to 18 cores, but most machines only go up to 8. This can be an ad hoc network of workstations or a dedicated render farm with 10s or 100s of render nodes, each with dozens of CPU cores. It shares render jobs across multiple networked computers. Single CPU workstations feature anywhere from 2 to 18 cores and up to 256GB RAM.ĭual CPU workstations have anywhere from 8 to 36 cores and up to 1TB RAM.įor hardcore users, distributed rendering takes rendering to a whole new level. ![]() These come with one or two CPUs, each with multiple CPU cores. Those serious about rendering will need a desktop workstation. Laptops typically peak at 4 CPU cores and 32GB RAM so are best suited to entry-level rendering. You can render on pretty much any type of laptop or desktop computer but choose a workstation-class machine as the components and cooling are designed specifically for compute intensive workloads. V-Ray RT, Nvidia Iray, Lightworks Iray+ and AMD FireRender). However, a growing number can use the GPU for rendering (e.g. The GPU is only used for interactive 3D graphics in most rendering software. Use fast Solid State Drives (SSDs) to move data quickly. If you run out of memory, rendering data will need to be moved in and out of hard drive swap space, which can be slow. Instead, just ensure you have enough to handle complex scenes. ECC is only available on Intel Xeon, not Intel Core.Īdding more GB won’t make your render go faster. Go for ECC memory to protect against crashes (you don’t want your overnight renders to fail). HT can boost rendering performance by up to 15% so it’s an important consideration when choosing a CPU. So a quad core processor with HT actually has eight virtual cores (or threads). Most (but not all) workstation-class CPUs feature Intel Hyper-threading (HT), a virtual core technology that turns each physical CPU core into two virtual cores. do not choose a CPU with lots of cores but a very low GHz. ![]() Therefore, it is important to find the right balance i.e. However, when choosing a CPU for a workstation, don’t forget a high GHz processor is essential for general system performance (Operating System, CAD and 3D graphics). To get a rough idea of comparative performance of chips from the same family of CPUs, multiply the GHz by the number of cores. As a rule of thumb, doubling the number of cores halves the rendering time. The more cores you have, the faster the render. When you have multiple GPUs connected with NVLink, you will see a difference in the available GPU Memory in the Real-time view.Rendering absolutely hammers the processor so the CPU is arguably the most important component when choosing rendering hardware.Įach CPU features multiple processors (called cores). For example, when you use server 8 at iRender with 6xRTX 3090 GPUs and NVLink, the server will provide a combined 144 GB vRAM of GPU memory.
