General info

The base and maximum clock speed of the CPU AMD A9-9420, 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: 3.00 GHz   CPU Cores: 2
Turbo (1 Core): 3.60 GHz   Turbo (2 Cores): 3.00 GHz
Hyperthreading: No   Overclocking: No

Internal Graphics

Some manufacturers complement their CPUs with graphic chips, such a solution being especially popular in laptops. The higher the clock frequency of a GPU is and the bigger its memory, the better.

Used in: Unknown

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.

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.

iGPU - FP32 Performance (Single-precision GFLOPS)

This test serves for determining the performance of integrated graphics in Intel and AMD processors. The result is the estimated computing power in the Single-Precision FP32 mode
