Snapdragon 660 and 630: Qualcomm brings Kryo and LTE Cat. 12 into the upper class
Qualcomm brings the Kryo CPU for the first time from the premium segment into the upper class. The new Snapdragon 660 Mobile Platform comes with Kryo 260, Adreno 512, X12 modem and other new features. Downwards, Qualcomm’s new top class will be rounded off with the Snapdragon 630 Mobile Platform.
Snapdragon 660 and Snapdragon 630 release the Snapdragon 653 and Snapdragon 626 from Qualcomm. The new chips are pin-compatible with each other, so that only one common platform has to be developed for two different terminals.
The biggest innovation of the faster of the new chip is that Qualcomm offers for the first time off the Snapdragon 820/821 as well as Snapdragon 835 (test) the Kryo CPU in the smaller 600 series. The Snapdragon 660 Mobile Platform has been ghosting for quite some time through the rumored kitchen. According to Qualcomm, the new SoC is now available, so that this quarter is expected with first devices

Kryo 260 with important Efficiency cores
The Snapdragon 660 changes from the old 28nm production to 14nm LPP from Samsung. Modern production is expected to result in approximately two hours longer running times than with the Snapdragon 653. The ARMv8 semi-custom design Kryo 260 comes with four up to 2.2 GHz fast performance cores and 1 Mbyte L2 cache as well as four up to 1.8 GHz fast Efficiency cores with also 1 MByte L2 cache for use. The performance should be 20 percent higher than the Snapdragon 653 with four ARM Cortex-A72 and four Cortex-A53 fail.The Pro Cluster doubled cache as well as the use of the Kryo 260 also for the Efficiency cores show how important the cluster has become for Qualcomm and how much of it is next to the new production at the longer running times. The same measures were last seen with the Snapdragon 835. Compared to the Snapdragon 653, the efficiency of the 660 is four times the computational time.
Adreno 512 adds 30 percent more power
To the new Adreno-512-GPU Qualcomm gives as usual only a little information. There is only a rough indication of the power that should be up to 30 percent higher than the 600 MHz fast Adreno 510 from the Snapdragon 653, 652 and 650.
Connectivity at all points
The connectivity of the chip has completely revised Qualcomm, starting with LTE over WLAN and Bluetooth. Instead of the X9 modem, the Snapdragon X12 is now installed with the new SDR660 RF transceiver. The X12 modem was previously reserved for the Snapdragon 820/821 and delivers up to 600 Mbit / s in the downstream (LTE Cat. 12) and up to 150 Mbps in the upstream (LTE Cat. 13). WLAN, and Bluetooth, Qualcomm has changed from the ac standard with 1 × 1 configuration and version 4.1 to 2 × 2 MU-MIMO and version 5.0. Also new is the support of the navigation satellites system Galileo and QZSS, which supplement GPS, GLONASS and BeiDou. Qualcomm promises improvements in efficiency, precision, and heat generation during operation for all connectivity.

The information flow from the connectivity and sensor technology of the smartphone unites Qualcomm in the so-called “All-Ways Aware Hub”, which is to carry out the important always-on function of a smartphone or tablet with low energy consumption. Here, information from DSP, WLAN, Bluetooth, location determination, 3G, LTE and the entire sensor system are used. Data from the DSP as well as the CPU and GPU flow into Qualcomms on the SoC integrated machine learning platform.
Snapdragon 630 with LPDDR4X
Snapdragon 625 and 626 have already been manufactured in 14 nm LPP at Samsung, so there is no change for the new Snapdragon 630. Unlike the Snapdragon 660, there is no change to the cryo CPU. Qualcomm maintains the CPU build-up from a total of eight cores of the type ARM Cortex-A53, each clocking four cores but differently, which was not the case at up to 2.2 GHz on all eight cores.Four of the Cortex-A53s reach up to 2.2 GHz, while the other four are operated as Efficiency clusters with a maximum of 1.8 GHz, although all eight cores are of the same type. However, the memory interface was bounced from 1 x 32 bit single-channel with LPDDR3 and 933 MHz to 2 × 16-bit dual-channel with support for Samsung’s efficient LPDDR4X and 1.333 MHz. Up to 8 GB of RAM support Snapdragon 630 and 660. For the CPU, Qualcomm does not name any performance enhancement.

New chip is suitable for tabletsThe new Adreno 508 GPU, which is the successor to the 650 MHz fast Adreno 506 of the Snapdragon 626 and 625, looks different. Also here is missing for the new model a Taktangabeabe, however, the performance according to Qualcomm also have been increased by 30 percent. The Snapdragon 630 now supports slightly higher display resolutions than before: up to 2,048 × 1,536 instead of 1,920 × 1,200 pixels are possible, so that tablets can be equipped with the 4: 3 format.Almost all improvements in connectivity are also present in the Snapdragon 630, including the X12 modem, Bluetooth 5.0 as well as support from Galileo and QZSS. Only the better WLAN is reserved for the higher SoC, the Snapdragon 630 stagnates with a simple stream with 1 × 1 configuration. Quick Charge 4 and Spectra 160 ISPThe common changes on both platforms include the upgrade to QuickCharge 4 and the support of USB 3.1 over Type C – previously, 2.0 was possible. According to internal Qualcomm measurements, the proprietary fast-charging technology should provide a five-hour runtime with a 2.750 mAh battery within five minutes. QuickCharge 4 builds on the USB Power Delivery standard and extends it with its own security features, providing consistent loading times, efficiency, and low temperatures with backwards compatibility with QuickCharge 3.0.

Onboard both models is the Spectra 160 ISP. The image processor is a smaller offshoot of the Spectra 180 from the Snapdragon 835, but still supports many features of the top model. These include, in particular, the electronic image stabilizer of the third generation, which is supposed to provide shake-free recordings in the video mode, as well as the support of hybrid autofocus systems and the use of two sensors, which can also be equipped with optical zoom and novel Bayer matrices. Both chips support 4K video recordings as well as playback of 4K files.
End devices in this and next quarter
is now offering the Snapdragon 660 Mobile Platform, and the first devices are expected for this quarter, the launch of the Snapdragon 630 Mobile Platform is scheduled to be completed by the end of the month, with end devices expected to range between July and September during the third quarter ,
