![]() The 2500K is pushing single-core performance at 124 cb marks, with multi-core at 460 marks. Using Cinebench for some quick synthetics, we’re seeing the i5-2500K operate expectedly at the bottom of the bench. At least, compared to the i5 CPUs.Ī trivial overclock to 4.5GHz on the i5-2500K moves us up to an 82-minute render time - absolutely a worthwhile improvement, if you’re stuck on this CPU and rendering things. If you bought an i7-2600K back in the day, you’re still in decent shape in this particular benchmark. To provide some perspective for Sandy Bridge, the same-gen Core i7-2600K can render the scene in about the same time as the i5-6600K ($240) at 74 minutes. If you’re rendering using the CPU – as you might do if running both the GPU and CPU on a render task – then the upgrade is clearly substantial. That’s about 30 minutes faster than the 2500K, or a reduction of about 31% time required. A modern CPU, like last gen’s i5-6600K, is able to complete the task in 73 minutes. The 3570K CPU, released in 2Q12, completes the frame in 94 minutes. The Intel i5-2500K with stock frequency settings is able to render our scene in 106 minutes, making it the slowest device on the bench by a long-shot. We already talked i7 numbers in our 7700K review, so let’s focus on the Core i5 CPUs. The additional threads are fully utilized for each 16x16 tile that we render, so 2x the threads equates 2x the active in-flight tiles being rendered. During GPU rendering, for instance, the fur monkey stresses GPU memory in unique ways.Īs the chart demonstrates, this is a benchmark where multithreaded CPUs really shine. We’re processing fur (bottom left), motion blur (bottom middle), transparency, reflectivity and ray traces, and solid materials.Įach monkey has different effects applied, all stressing the components in different ways. The final image is shown below, for the curious. The benchmark process is to render a single frame of a 4K image that GN’s Andrew Coleman created, including several different effects and material types that impact render performance. Our Blender benchmarking is defined on (see: CPU Testing Methodology), and has been deployed since the i7-7700K review that we recently posted. ![]()
