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

Suggested PSU: We assume that we have an ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.

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 the PDT of Amlogic S905X3 is lower. 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
Broadcom BCM2711 400,275
Amlogic S905X3 74,472

The difference is 437%.

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
Broadcom BCM2711 1,015
Amlogic S905X3 414

The difference in performance is 145%.

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.

With Android:

Geekbench 4 - Multi-core & Single Core Score - Android
Broadcom BCM2711 976
Amlogic S905X3 773

In single core, the difference is 26%. In multi-core, the difference in terms of gap is 15%.

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.

With Android:

Geekbench 5 - Multi-core & Single Core Score - Android
Broadcom BCM2711 234
Amlogic S905X3 132

In single core, the difference is 77%. In multi-core, the difference in terms of gap is 47%.

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.
