Qualcomm Snapdragon 630 vs 625: What’s The Difference

by Michele Ingelido 7

In 2016, Qualcomm unveiled the Snapdragon 625, a SoC which has become the most loved one when it comes to midrange smartphones sold at an affordable price. The reason for its success is the perfect combination of power and efficiency, which helped this processor provide good performance with an incredibly low energy consumption. This year, Qualcomm launched its successor (after launching SD626, an overclocked variant with a more advanced Bluetooth version): Snapdragon 630. It is an improved version of the older SoC. In this comparison, we will examine the main differences between Qualcomm Snapdragon 630 vs 625.

An important difference between Snapdragon 630 vs 625 is the clock frequency: 2.2 GHz vs 2 GHz. According to Qualcomm, Snapdragon 630 offers up to 30 percent higher performance than SD626, so it should be more than 30 percent better than SD625 in terms of performance. The GPUs are also different and the Adreno 508 found in SD630 offers up to 30 percent more performance than Adreno 506 too. At a first glance, it seems there is not much difference, but as you see it is not so. Snapdragon 630 also has more advanced connectivity options. Its Snapdragon X12 modem has 2x higher download speed and more advanced Wi-Fi and Bluetooth connectivity.

While in terms of camera and display there are no significant differences (Snapdragon 630 remains slightly better), the fast charging technology is way better. Quick Charge 4 has a charging speed which can be up to 15 percent faster than Quick Charge 3.0, and it is also a safer technology. Snapdragon 630 is also more power efficient than its opponent. It’s worth noting that not every aspect of each SoC may be supported on the phones which have been equipped with these processors. For example, a phone may be equipped with the Qualcomm Snapdragon 630 but it may not have the support to Quick Charge 4.0 because the company has decided to remove it or to opt for its own fast charging technology.

    It’s hardly an update. The real update is sd636, no need for sd630.

    You forget about sd630 have dual channel ram lpddr4

    Same o, same o… Same CPU, GPU & DSP & on same lithography. Newer cellular modem DSP & that is actually only difference not that much people will have much use of it & certainly everyone could live without it. Everything else is QC PR pure lies! 30% performance uplift on CPU side? It’s 10% hire clocked same core’s which translates into 8.5~9% faster & on the price of 25% higher power consumption. On the other side the same GPU but with twice as much RAM bandwidth is capable to achieve promised 25~30% performance advantage with only minor bump regarding power consumption. & the last part QC quick charge x. x support while 95% of the phones with the SoC will ship only with this day’s standard 2.2A charger. Puh not worth upgrading at all & worth purchasing only when prices drop to 2~3$ difference to S625 powered models (probably never).

    if SD 630 does NOT appear in Redmi Note 5, then the phone will be a FAILURE !

    • I really hope Xiaomi uses the SD 636, not the 630, but if they dare use the 625 again, they’ll have lost me!

  • For the display, what’s the difference in the use of a FHD+ ? Isn’t it the same thing?
    Then why are the pixels count different Between the two which is better? Am a bit confused. Help!
