Price: prices can change over time. For technical reasons, they are not updated in real time. This is only an average of the results on the first page of each product, whether new or used. Shipping costs have not been integrated. To know the final price of the product, please go to the form of the shop. If no price is indicated, it means that we did not find any offers during the last update.

We can better compare what are the technical differences between the two processors. We see that the two processors have an equivalent number of cores, the maximum frequency of Qualcomm SM8150-AC Snapdragon 855+ is greater, that the thermal dissipation power of Qualcomm SDM636 Snapdragon 636 is less. The Qualcomm SM8150-AC Snapdragon 855+ was designed earlier.

Ratios: we first consider the average for the new price if available, the average for the used price otherwise. Performance / global cost ratio: This is the ratio of performance on Geekbench 4, divided by the cost of the product + the cost of electricity over 5 years for a duration of use of 13 hours per day.

Performances :

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

AnTuTu - Total score
Qualcomm SM8150-AC Snapdragon 855+ 480,000
Qualcomm SDM636 Snapdragon 636 140,000

The difference is 243%.

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
Qualcomm SM8150-AC Snapdragon 855+ 22,890
Qualcomm SDM636 Snapdragon 636 12,480

The difference in performance is 83%.

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 64-bit:

Geekbench 4 - Multi-core & single core score - Android 64-bit
Qualcomm SM8150-AC Snapdragon 855+ 3,730
Qualcomm SDM636 Snapdragon 636 1,441

In single core, the difference is 159%. In multi-core, the differential gap is 116%.
