General info

The base and maximum clock speed of the CPU Intel Core i9-11900K, number of processing cores and threads.

CPU Cores and Base Frequency

The general performance of a CPU can easily be determined based on the number of its cores and the thread count, as well as the base frequency and Turbo frequency. The more GHz and cores a CPU has, the better. Please note that high technical specs require using a powerful cooling system and a quality chipset (check VRM on the motherboard).

Frequency: 3.50 GHz   CPU Cores: 8
Turbo (1 Core): 5.30 GHz   Hyperthreading: Yes

Devices using this processor

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

Used in: Gaming PC

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.

Geekbench 5, 64bit (Multi-Core)

Geekbench 5 software suite shows benchmark testing results of the memory performance and speed of the multi-core processor. Here the hyperthreading ability is counted.

Estimated results for PassMark CPU Mark

It tests entire and overall performance of the central processing unit (mathematical calculations, compression and decompression speed, 2D&3D graphic tests). Please note that data can differ from the real-world situations.

Monero Hashrate kH/s

Using a Graphics Card (GPU) is the ideal way to mine Monero. While it requires substantially more investment compared to using a CPU, its hash rate is significantly higher
