In today’s comparison, we are going to look at three well-established mobile processors, developed by Qualcomm – we are talking about Snapdragon 625, Snapdragon 617 and Snapdragon 430. Below, we will share information about each of the chips, compare their benchmark results, and finally conclude with surface overheating tests. For this purpose, we use the results recorded with Lenovo P2, Moto G4 and Lenovo K6 respectively.
|Specs sheet||Snapdragon 625||Snapdragon 617||Snapdragon 430|
|Process||14 nm||28 nm||28 nm|
|Frequency||up to 2.0 GHz||1.21 GHz – 1.52 GHz||1.4 GHz|

We start off with Snapdragon 625 which is a 64-bit Qualcomm chip manufactured through a 14nm technological process. Is can be found in the smartphone Lenovo P2. The mobile processor has eight Cortex-A53 cores running with a frequency of up to 2GHz. Its specs also include an X9 modem, providing Cat. 7 LTE connectivity or in other words download speed of up to 300Mbps and up to 150Mbps upload speed. In addition, the mobile chip also supports Wi-Fi 802.11ac, NFC, the Quick Charge 3.0 technology for fast charging, Full HD screens, up to 24MP cameras and 4K video recording. Here, the present GPU is Adreno 506.

Moving on to Snapdragon 617 that comes in its MSM8952 modification found in Moto G4. This is a 64-bit mobile chip by Qualcomm which has eight Cortex-A53 cores divided into two sections – the first four cores run at frequencies up to 1.21 GHz, while the other four – at 1.52GHz. Snapdragon 617 is manufactured through a 28nm technological process. It boasts support of QuickCharge 3.0 technology that offers four times faster charging of the mobile device compared to standard charging, as well as the Qualcomm Safeswitch technology that allows you to remotely deactivate the device in case you lose it or it is stolen. The specs sheet is complemented by LTE Cat. 7 support with a download speed of up to 300 Mbps, Wi-Fi 802.11n/ac, LPDDR3 933MHz memory, Bluetooth 4.1, Full HD displays, up to 21MP cameras as well as Full HD video recording at 60 fps. The Adreno 405 GPU takes care of the graphics performance running at 550MHz.

And last but certainly not least – Snapdragon 430, which again is a 64-bit mobile processor manufactured through a 28 technological process. It can be found in Lenovo K6. It has eight Cortex-A53 cores, whose clock speed reaches up to 1.4GHz. Its specs include Full HD display support, up to 21MP camera sensors with up to Full HD video capturing (30fps), Quick Charge 3.0 technology for faster recharging (38% more effective than Quick Charge 2.0), Wi-Fi 802.11ac, Bluetooth 4.1, NFC and LTE Cat 4 with download speeds of up to 150Mbps. Here, the present GPU is Adreno 505.

All three chips offer relatively smooth work, however the comparison between them is definitely intriguing. In order to do this, we performed several benchmarks testing both computing and graphics power. As you may see, the results are displayed in the table below.
|Benchmarks||Qualcomm Snapdragon 625||Qualcomm Snapdragon 617||Qualcomm Snapdragon 430|
|Geekbench 3 (Multi-Core)||3845||2700||
|Vellamo 2 Metal||833||
|Vellamo 3 Metal||1792||1469||1065|
|Pi – 10 mil. (lower is better)||–||32.746||33.212|
|GFXBench 2.7 T-Rex (offscreen)||23||17||16|
|GFXBench 3 Manhattan (offscreen)||9.9||6.6||7.1|
|3D Mark Ice Unlimited||13823||9853||
We carried out out temperature with eagerness, loading the three devices with continuous 3D gaming simulated with the help of the Epic Citadel app. Immediately after this, we measured the temperatures in three sections of the smartphone’s back. We notices that in Moto G4 the temperatures were slightly higher than the other two devices but the values are not that worrying. The photos below display the registered temperatures in the three sections of each smartphone’s back.
