A8-3870K vs. Core i3-2105 CPU Review

Let’s take a look at the highest-end CPU with integrated video from AMD (“APU”), the A8-3870K, and compare it to the A8-3850 and to its contenders from Intel: the Core i3-2105 and Core i3-2100.

Cinebench 11.5 is based on the 3D software Cinema 4D. It is very useful to measure the performance gain given by having more than one CPU installed on the system when rendering heavy 3D images. Rendering is one area in which having more than one CPU helps considerably, because usually, rendering software recognizes several CPUs. (Cinebench, for instance, can use up to 16 CPUs.)

Since we were interested in measuring the rendering performance, we ran the test called “Rendering x CPUs,” which renders a “heavy” sample image using all available CPUs or “cores” – either real or virtual – to speed up the process. (On CPUs with Hyper-Threading technology, each core is recognized as two cores by the operating system.)

A8-3870K vs. Core i3-2105

Here the advantage switched to the CPUs from AMD, since they are quad-core parts, while the CPUs from Intel are dual-core products with Hyper-Threading technology. Here the two CPUs from AMD achieve the same performance level, and the A8-3870K was 15% faster than the Core i3-2100 and 17% faster than the Core i3-2105.
