Cinebench R11.5, 64bit (Single-Core)

This synthetic test will help you determine the real computing power of a single core in the central processing unit. Cinebench R11.5 is based on MAXON CINEMA 4D and employs various testing scenarios

Cinebench R11.5, 64bit (Multi-Core)

Cinebench R11.5 carries out simultaneous cross-platform tests on all the processor’s cores. By running realistic 3D scenes, this benchmark will reveal all the potential of your Intel or AMD single-unit processor

Cinebench R15 (Single-Core)

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. It is the updated version of Cinebench 11.5. As all new versions, the updated benchmark is based on Cinema 4 Suite software

Cinebench R15 (Multi-Core)

Cinebench R15 can be used for multi-core processor performance benchmark testing. The test produces precise and accurate results. This benchmark is the updated version of the Cinebench 11.5 which is based on Cinema 4 Suite soft.

Cinebench R20 (Single-Core)

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 R23 (Single-Core)

Cinebench R23 is the newest instalment of the most popular CPU Rendering Benchmark Single-Core Cinebench. We have the Score Results for all modern Processors

Cinebench R23 (Multi-Core)

Cinebench R23 is the newest instalment of the most popular CPU Rendering Benchmark Multi-Core Cinebench. We have the Score Results for all modern Processors

Geekbench 3, 64bit (Single-Core)
