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 turbo frequency of Rockchip RK3328 is bigger, that the thermal dissipation power of Rockchip RK3328 is less. The Broadcom BCM2837B0 was designed earlier.

Performances :


Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.


AnTuTu - Total score
Rockchip RK3328 33,120
Broadcom BCM2837B0 23,020


The difference is 44%.


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.





On Android 64-bit:

Geekbench 4 - Multi-core & single core score - Android 64-bit
Rockchip RK3328 563
1,454
Broadcom BCM2837B0 498
1,097


In single core, the difference is 13%. In multi-core, the difference in terms of gap is 33%.


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.
