We can better compare what are the technical differences between the two processors.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

We see that the two processors have an equivalent number of cores, the maximum frequency of Amlogic S905X3 is greater, that their respective TDP are of the same order. Both were produced in the same year.

Performance comparison with the benchmarks:

Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench.

AnTuTu - Total score
Amlogic S905X3 74,472
Rockchip RK3318 46,368

The difference is 61%.

AnTuTu is one of the most popular apps in the world to evaluate and compare the power of a mobile device with the competition. It tests above all the power of calculation, the display of Web pages, the modeling of decorations in 3D, the management of the memory, the transfer of data.

Android PassMark - CPU Mark
Amlogic S905X3 414
Rockchip RK3318 156

The difference in performance is 165%.

PassMark is a benchmarking software that performs several performance tests including prime numbers, integers, floating point, compression, physics, extended instructions, encoding, sorting. The higher the score is, the higher is the device capacity.

On Android:

Geekbench 4 - Multi-core & single core score - Android
Amlogic S905X3 773
Rockchip RK3318 522

In single core, the difference is 48%. In multi-core, the differential gap is 79%.

Geekbench 4 is a complete benchmark platform with several types of tests, including data compression, images, AES encryption, SQL encoding, HTML, PDF file rendering, matrix computation, Fast Fourier Transform, 3D object simulation, photo editing, memory testing. This allows us to better visualize the respective power of these devices. For each result, we took an average of 250 values on the famous benchmark software.

On Android:

Geekbench 5 - Multi-core & single core score - Android
Amlogic S905X3 132
Rockchip RK3318 92

In single core, the difference is 43%. In multi-core, the differential gap is 77%.

Geekbench 5 is a software for measuring the performance of a computer system, for fixed devices, mobile devices, servers. This platform makes it possible to better compare the power of the CPU, the computing power and to compare it with similar or totally different systems. Geekbench 5 includes new workloads that represent work tasks and applications that we can find in reality.
