CPU speed
2 x 2.15GHz & 2 x 1.6GHz
1 x 2.84GHz & 3 x 2.42GHz & 4 x 1.78GHz
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
CPU threads
More threads result in faster performance and better multitasking.
Uses big.LITTLE technology
✔Qualcomm Snapdragon 820 MSM8996
✔Qualcomm Snapdragon 855
Using big.LITTLE technology, a chip can switch between two sets of processor cores to maximize performance and battery life.
For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximize battery life.
Uses HMP
✖Qualcomm Snapdragon 820 MSM8996
✔Qualcomm Snapdragon 855
Heterogeneous Multi-Processing (HMP) is a more advanced version of big.LITTLE technology. In this setup, a processor can utilize all cores at the same time, or just a single core for low-intensity tasks. This can provide powerful performance or increased battery life respectively.
