Today at Qualcomm’s 2016 4G/5G Summit in Hong Kong, the company announced several new additions to its low- and mid-tier Snapdragon SoC lineup, including the Snapdragon 427, 626, and 653. Each new Snapdragon SoC builds on its predecessor, adding a few key features.

The new Snapdragon 653 is the “Pro” version of the existing 652 similar to how the Snapdragon 821 is a “Pro” version of the 820. Qualcomm raised the max frequency of the Snapdragon 653’s four ARM Cortex-A72 CPUs to 1.95GHz, up from 1.80GHz in the 652, but kept the max frequency of the four ARM Cortex-A53 CPUs the same. There’s still an Adreno 510 GPU in the new SoC, but its peak frequency has also been increased.

The Snapdragon 653 still uses LPDDR3-1866 memory with 14.9GB/s of bandwidth like the 652, but doubles the amount of addressable RAM from 4GB to 8GB. This is a prudent extension given the current trend towards 4GB and 6GB configurations for Android phones in the mid-range segment and flagship phones pushing towards 8GB.

The Snapdragon 653 also received a modem upgrade: The Snapdragon X9 LTE modem replaces the Snapdragon X8 LTE modem in the 652. The X9 still supports up to 300Mbps on the downlink using 2x20MHz carrier aggregation and 64-QAM (Category 7), but boosts the uplink to 150Mbps by adopting 64-QAM (Category 13). The X9 can also improve call clarity when using the Enhanced Voice Services (EVS) codec for VoLTE calls.

The Snapdragon 625 gets a new “Pro” version too in form of the Snapdragon 626. Both of the Cortex-A53 CPU clusters get a boost from 2.0GHz to 2.2GHz, but Qualcomm did not disclose the frequency of the Adreno 506 GPU.

The Snapdragon 625’s X9 LTE modem carries over to the 626, but the new SoC updates Bluetooth support from 4.1 to 4.2. The Snapdragon 626 also supports Qualcomm’s TruSignal antenna boost technology, which optimizes reception in weak signal strength conditions and from the attenuation that occurs when holding a phone. Working together with the antenna matching tuner (a separate IC that’s part of Qualcomm’s RF360 suite) and transceiver, the X9 LTE modem in the Snapdragon 626 performs the processing that enables the dynamic tuning.

The Snapdragon 427 (MSM8920) is the newest member of the lower-tier 400 series, which now encompasses seven Snapdragon SoCs (400, 412, 415, 425, 427, 430, 435), ranging from the Snapdragon 400—containing either a dual-core Krait 300 or quad-core Cortex-A7 CPU and an Adreno 306 GPU—to the 435 and its octa-core Cortex-A53 CPU running at up to 1.4GHz with an Adreno 505 GPU and X8 LTE modem.

Like the other two new SoCs, the Snapdragon 427 is an update to an existing SoC. It has all the same features as the Snapdragon 425, including a quad-core A53 CPU running at up to 1.4GHz, an Adreno 308 GPU, a dual ISP supporting up to a 16MP camera, and single-channel LPDDR3-1334 memory all on a 28nm LP process. The sole change is an upgrade from the X6 LTE modem (Category 4) to the X9 LTE modem (Category 7/13), boosting peak downlink/uplink performance from 150Mbps/75Mbps to 300Mbps/150Mbps. This gives the new Snapdragon 427 the highest performing modem of the 400 series—and the only SoC in this tier to support Qualcomm’s TruSignal technology—but the 430 and 435 contain a faster GPU and ISP. Because the Snapdragon 427 maintains full pin and software compatibility with the 425, 430, and 435, it offers OEMs an easy path to adding the X9 LTE modem to their products.

Both the Snapdragon 653 and 626 SoCs should be commercially available by the end of 2016, while the Snapdragon 427 should appear in commercial devices in early 2017.

    Indeed, 8x A53 is probably the dumbest configuration possible. Reply

    Moto Z play is 8x A53, it did well in real world usage. Reply

    Um 8xA53/A7 are not dumb and it does more then just look good on benchmarks. I have done several experiments with these types of phones. I turned two and 4 of the cores off to see the effect it would have on performance. (switching between the big and little clusters) and saw big performance drops in real world use games,web,texting so the argument that a smart phone or computer does not get any benefit from using more then 4 cores at the same time is bullcrap.

    So who will make these chips? Samsung or TSMC? Reply

    SD 652 is a great chip. My Le Eco 2 beats Note 5(Exynos 7420) in terms of sheer speed. Remember, Note 5 was released late 2015 and received great reviews even in 2016. The only reason Qualcomm didn't want it to be on 14 nm is it didn't want 652 cores eclipsing SD 820. Reply

    Because Kryo cores aren't doing well in performance-efficiency comparisons. The A72 is a very good core when you need fast bursts of high performance.

    Come to think of it, the SD 65x chips look like quick hacks that turned out to be surprisingly good. The A53 and A72 cores are stock ARM designs, the GPU is a midrange Adreno, modem speeds aren't at the top, memory speed and bandwidth are constrained compared to the 82x chips - but the whole combination is good enough for most users. I'd rather have 80% of a flagship's performance while getting double the battery life.

    I agree. Performance wise, 652 matches sd 808 which was brought out as an alternative to overheating 810. So last year's biggy is today's mid-range.😀😀 Reply
  • CloudWiz - Tuesday, October 18, 2016 - link

    SD808 was never meant for true flagships as dual A57 couldn't keep up with the quad A57 in 7420 and definitely not the dual Twister in A9. The only reason it was competitive with the 810 is because the 810 couldn't keep its A57 running for long. Also, the 652 actually should offer better performance than the 808 because the quad A72 brings not only double the cores but also an IPC increase while maintaining the clock speed. Reply

    Most mobile phone makers are just spamming ram, i.e. 8GB. Seriously, I am not sure if there is a need to even have that much ram on the mobile phone. This is a case of trying very hard to differentiate. Also, the race to increase ram will quickly make Android a very memory hungry OS since there is plenty of ram to use. Older phones with even 3/4GB may start struggling to keep up. Reply
  • fred666 - Tuesday, October 18, 2016 - link

    You understand it's the maximum supported by the CPU, right? A desktop Core i5 can have up to 64 GB of RAM. Most users will use it with 4-16 GB and that's fine. Reply
