Qualcomm’s new Snapdragon 660 and 630 mobile platforms bring high-end features to the mid-range

Improved performance, enhanced photography, better connectivity, and longer battery life – these are some of the main promises of the new Snapdragon 660 and Snapdragon 630 mobile platforms that Qualcomm has announced today. According to the company, the new chipsets are created to bring “more affordable high quality features for more smartphones and tablets, with little compromise on power”. The Snapdragon 660 is a successor of the Snapdragon 653 SoC, and the new Snapdragon 630 is an improved version of the 626 model, but both of them should give users significant improvements in several key areas.


As we expected before, the Snapdragon 660 chipset is built using the 14nm FinFET process, but unlike its 28 nm predecessor, the Snapdragon 653, it makes use of new Kryo 260 CPU cores. They work in the usual 4+4 configuration, in which the faster 2,2 GHz cores take care of the heavy-duty tasks, while the lighter ones are served by the other four cores running at a clock speed of 1.9GHz. Qualcomm claims the Kryo 260 CPU has up to 20% higher performance than the previous generation. 

For the first time in the company’s 600 series platform, the Snapdragon 660 also makes use of the Adreno 512 GPU, which promises 30% improvement in graphics performance compared to the previous generation, the Adreno 510 GPU. The Snapdragon 630, on the other hand, comes with a 30% increase inGPU performance with the Adreno 508 and a 10% more CPU performance than the Snapdragon 625 processor, according to the company’s data. Both new chips support up to 8GB maximum memory. 

Additional improvement is that Snapdragon 660 and 630 provide Vulkan API support as well as integrated 4K video capture and playback capabilities. This means that users can record high-definition videos at 30 frames per second, straight from the device.


Qualcomm Snapdragon 660 and 630 support the company’s Spectra 160 camera image signal processor (ISP). This chip should improve our photographic experience by producing more natural skin tones with focus on low light photography and improved power efficiency. 
The new ISP comes also with improved support for dual cameras as well as features such as smooth optical zoom, bokeh effects, dual pixel autofocus, and improved video stabilization. 


Qualcomm’s new chips feature a Snapdragon X12 modem that is claimed to offer up to 600Mbps of downlink data rates. The Snapdragon 660 comes with support for 2×2 MU-MIMO 802.11ac Wi-Fi, which the company says offers twice as much data throughput and up to 60% lower download power consumption, when compared to the Snapdragon 652.
Both of the new chips also support Bluetooth 5.0, which has four times the range and twice the transmission speed of the previous Bluetooth 4.2 technology. 

Power efficiency

With Snapdragon 660 and Snapdragon 630, the Qualcomm Quick Charge 4 technology is now coming to the company’s 600 series of SoCs as well. It is claimed to offer up to 5 hours of talk time in just 5 minutes of charging and up to 50 percent battery life in just 15 minutes of charging.

Machine learning

With the new mobile chips, Qualcomm allows developers and OEMs to use machine learning to power user experiences by using Snapdragon Neural Processing Engine SDK and offers support for the open source TensorFlow, Caffe, and Caffe2 machine learning software frameworks. All of these software tools will be supported by the CPU, GPU, and Qualcomm’s Hexagon digital signal processor (DSP), as well as its HVX vector extensions. 


The Snapdragon 660 is already available to device makers, while the Snapdragon 630 will be available towards the end of this month, Qualcomm says. According to recent speculations, the chip will power the new dual-camera Samsung Galaxy C we told you about a week ago. Other phones that are rumored to employ the Snapdragon 660 include the Xiaomi Redmi Pro 2, Xiaomi Mi Max 2, Oppo R11, Vivo X9s Plus, and the Nokia 7 and Nokia 8. We don’t know yet which phone models will use the Snapdragon 630.

The SD 660 is better in some ways compared to last year's SD 820. For instance the SD has USB 3.1 support, as well as Bluetooth 5.0. It even supports 2 cameras simultaneously with up to 16 mp and 24 mp. The SD 820 can handle up to one 28 mp camera. The SD 660 even has better cores with 4 cores based on Cortex-A73 cores. Whereas the SD 820 has 4 cores based on Cortex-A57 cores. The SD 660 even supports dual channel DDR4 1866 MHz ram. As well as Vulkan graphics.

The gpu is much inferior. Isn't it?

"Whereas the SD 820 has 4 cores based on Cortex-A57 cores." First generation Kryo developed from the ground. At the time it was either fully custom or stock ARM cores. Only at the middle of past year, ARM has started its semi custom "built on ARM Cortex" business.

This. First generation Kryo is completely different to the A57 and A72 Kryo has much worse integer IPC than the A73, A72 and A57 Kryo has much better floating point IPC than the A73, A72 and A57http://www.anandtech.com/show/11201/qualcomm-snapdragon-835-performance-preview/2

I know they are custom cores. However Qualcomm has licensed​ from Arm all their reference designs. So that includes all of Arms Cortex cores. Do you not think Qualcomm isn't using or basing their cores off of Arms core reference designs? Of course Qualcomm uses Arm core designs, and then they modify them for their needs.

"At a high level, ARM offers three different types of licenses: POP, processor and architecture." http://www.anandtech.com/show/7112/the-arm-diaries-part-1-how-arms-business-model-works "Until now vendors had two main choices: Use one of the various available Cortex licenses, or get an architectural license and develop one's own microarchitecture based on ARM's ISA." "The common limitation of all current Cortex licenses however is that a vendor is not able to change any aspect of the microarchitecture. If a customer needed a feature that ARM's cores didn't provide, they had to go with an architectural license and develop their own microarchitecture from scratch." http://www.anandtech.com/show/10366/arm-built-on-cortex-license

If the Nokia 7 really comes with a SD 660, It'll be my next purchase.

Meh........ When Qualcomm introduced Krait, it is already available for not only high end but also midrange chipset. And now we have to wait a year for Kryo to appear on their midrange chipset.

Meh??? Kryo is crap compared to A72/A73, get your facts straight.

Snapdragon 650/652 was barely even used by OEMs. Let's hope this is not the same.

"This means that users can record high-definition videos at 30 frames per second, straight from the device." Where were we recording from before?
