Devices using this processor

You probably know already what devices use CPUs. These can be a desktop or a laptop.

Used in: Unknown

Cinebench R20 (Single-Core)

It is the updated version of the Cinebench R15 benchmark. This version provides improved benchmark accuracy at testing of processors. Cinebench R20 is based on Cinema 4 Suite. It is the software used to create 3D forms. The benchmark runs for single-core test procedure without counting of hyperthreading ability.

Cinebench R20 (Multi-Core)

It is the new version of the benchmark which is developed on the basis of Cinebench R15 (both versions are operated on the basis of Cinema 4 - the most popular 3D modeling software). Cinebench R20 is used for multi-core processor performance benchmark tests and hyperthreading ability.

Cinebench R15 (Single-Core)

It is the updated version of Cinebench 11.5. As all new versions, the updated benchmark is based on Cinema 4 Suite software. The latter is used for creation of 3D models and forms. Cinebench R15 is used for single-core processor performance benchmark test. The hyperthreading ability doesn't count.

Geekbench 5, 64bit (Single-Core)

Geekbench 5 benchmark is the newest software suit. It allows to account for the effect of memory performance on processor performance. Completely new algorithms provide the quite accurate benchmark testing results of the single-core CPU.

Blender 2.81 (bmw27)

We use Blender benchmark to trace performance of the central processing unit. Blender is the software for professional rendering and creating of 3D bodies which can also be animated. The testing results show you how fast the unit runs on the implementation of the multi-processing tasks. Here everything works on the principle that the faster rendering for 3D scenes, the better.
