Der Qualcomm Snapdragon 625 (SD625) ist ein Mittelklasse SoC für (Android basierende) Smartphones und Tablets. Er wird als erster seiner Klasse im 14 nm FinFET Verfahren gefertigt und integriert einen ARM Cortex-A53 Octa-Core Prozessor (8 Prozessorkerne) mit bis zu 2 GHz Taktfrequenz. Das integrierte X9 LTE Modem unterstützt 4G+ (Category 7) mit bis zu 300 Mbps Download und 150 Mbps Upload. Weiters ist eine Adrone 506 Grafikkarte integriert mit Support für Vulkan und OpenGL ES 3.1. WLAN wir 802.11ac unterstützt und Bluetooth in der Version 4.1. Der Speicherkontroller unterstützt LPDDR3 mit 933 MHz (daher wahrscheinlich Dual-Channel DDRL-1866). Die Prozessorperformance sollte vergleichbar mit dem HiSilicon Kirin 650 sein, welcher ebenfalls 8 Cortex-A53 Kerne mit bis zu 2 GHz integriert. Durch das kleinere Fertigungsverfahren ist jedoch der Stromverbrauch des SD625 wahrscheinlich besser und auch die Taktfrequenz kann wahrscheinlich länger gehalten werden.

Der Mediatek Helio P10 MT6755 ist ein ab Q3 2015 verfügbarer ARM-SoC (System-on-a-Chip) der oberen Mittelklasse, der sowohl in Smartphones als auch Tablets (hauptsächlich Android) eingesetzt werden kann. Er wird in 28 Nanometern gefertigt und verfügt über acht CPU-Kerne auf Basis der 64-Bit-fähigen Cortex-A53-Architektur, die mit maximal 2 GHz takten. Die Grafikeinheit namens ARM Mali-T860 MP2 bietet zwei Cluster bei 700 MHz. Weiterhin integriert sind ist ein LTE-Cat-6-Modem.
Prozessor
Der Cortex-A53 kann als Nachfolger des beliebten Cortex-A7-Designs betrachtet werden. Neben der von 32 auf 64 Bit verbreiterten Prozessorarchitektur (ARMv8-ISA), die unter anderem die Adressierung von mehr als 4 GB Arbeitsspeicher erlaubt, wurden auch weitere Details wie die Sprungvorhersage optimiert. Insgesamt steigt die Pro-MHz-Leistung dadurch deutlich an und liegt sogar etwas oberhalb eines Cortex-A9-Kernes. Die acht Kerne des MT6755 takten mit bis zu 2 GHz, sodass der SoC meist das Level des Kirin 930 erreicht.
Leistungsaufnahme
Der MT6795 wird in 28-Nanometer-Technik bei TSMC (HPC+) gefertigt und sollte unter Last eine mittelhohe Leistungsaufnahme aufweisen. Laut Mediatek ist der Chip auch für Smartphones geeignet und wird z.B. im Elephone P9000 eingesetzt.

Das Integrierte X9 LTE Modem unterstützt Cat. 7 und dadurch maximal 300 Mbps Download und 150 Mbps Upload. Weiters ist eine Adreno 506 Grafikkarte integriert mit Support für Vulkan und OpenGL ES 3.1. WLAN wir 802.11ac unterstützt (1x1 MU-MIMO max. 364 Mbps) und Bluetooth in der Version 4.1. Der Speicherkontroller unterstützt LPDDR3 (single channel). Die Videoengine unterstützt 1080p H.264 Encode und Decode und HEVC Decode.
A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.
With integrated graphics you don’t need to buy a separate graphics card.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

Performance
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.
More threads result in faster performance and better multitasking.
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.
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.
