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, they have a similar turbo frequency, that their respective TDP are of the same order. The Amlogic S905X4 was started more recently.

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 S905X4 101,519
Amlogic S905X3 74,472

The difference is 36%.

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 S905X4 576
Amlogic S905X3 414

The difference in performance is 39%.

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 S905X4 769
Amlogic S905X3 773

In single core, the difference is 1%. In multi-core, the difference in terms of gap is 1%.

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
Amlogic S905X4 129

In single core, the difference is 2%. In multi-core, the differential gap is 8%.

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.
