Qualcomm chips targeting cheap smartphones add 5G modem
The Snapdragon 690 chip contains the X51 modem, which supports data rates of 2.5 Gbps and upload speeds of 660 Mbps. The chip can connect to 5G networks in any part of the world, but it lacks the ability to access the fastest millimetre wave frequencies.

The chip also incorporates Qualcomm's Adreno 619L GPU, which bolsters performance up to 60% over its predecessor, bringing lusher colors, enhanced details and faster load times to video games on budget smartphones. The chip supports 120Hz screens for fast refresh rates and smooth scrolling. The memory subsystem is based on LPDDR4 lanes with up to 1.86 GHz clock speeds. The chip can accommodate up to 8GB of RAM, Qualcomm said.

The image signal processor (ISP) in the Snapdragon 690 can handle more advanced cameras in phones. The Spectra 355 has enhanced capture rates plus fast autofocus and other technology for shooting sharper, brighter video in more than one billion shades of color, the company said. The dual-core ISP can be connected to image sensors with up to 192 MP of overall resolution or dual cameras with up to 32 MP and 16 MP, Qualcomm said.

The chip can also connects to 4G networks with data transfer rates of up to 1.2 Gbps, more than double the maximum speed of the Snapdragon 675. The chip supports upload speeds of up to 210 Mbps on 4G networks. Qualcomm said it also added WiFi 6 and Bluetooth 5.1  to the processor, which also supports NFC, GPS and other global positioning systems. The new chip also interfaces to USB Gen 3 ports and DisplayPort over USB Type-C.

Lenovo, Motorola, LG, HMD and Sharp are among the phone manufacturers planning to sell 5G smartphones with the Snapdragon 690 in the second half of 2020, Qualcomm said.
