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. 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).
