Qualcomm has announced a new mid-range SoC called the Snapdragon 636 Mobile Platform. And it appears to be a toned down version of the Snapdragon 660.
Instead of the Adreno 512 on the 660, the Snapdragon 636 uses an Adreno 508 GPU. The new chipset which uses 14nm process also runs on Kryo cores (octa-core), with a maximum clock speed of up to 1.8GHz.
The CPU uses 64-bit architecture, and supports up to 8GB of LPDD4 RAM @ 1333MHz. The Snapdragon 636 can power 1080p FHD+ displays with 18:9 aspect ratios, and Dual ISPs (2 x image sensor processor) with its Qualcomm Spectra 160 14-but ISP and Qualcomm Clear Sight. The SoC is capable of supporting 16MP and 24MP cameras, with hybrid autofocus, optical zoom, zero shutter lag, has Bluetooth 5.0
The Snapdragon 645 offers all modern connectivity options including USB 3.1, Bluetooth 5.0, NFC, GPS, GLONASS, Beidou, Galileo, QZSS, SBAS, Assisted GPS, OTDOA. For mobile networks it supports 4G LTE using the X12 LTE modem with Cat 13 (150Mbps) uploads, and Cat 12 (600 Mbps) downloads with 3 x 20MHz CA 256-QAM downlink, 2 x 20MHz CA (Carrier Aggregation) and 64-QAM uplink.
The chipset is capable of supporting LTE on Dual SIM cards with VoLTE, Wi-Fi 802.11 ac, n, 11a/b/g/n @ 2.4/5GHz with 433 Mbps speeds, MIMO, MU-MIMO. 256 QAM.
Coming to the audio specs, the Snapdragon 636 uses Qualcomm Aqstic audio codec with a Dynamic range of 130dB, Dual oscillator (44.1kHz/48kHz), -109dB THD+N, and up to 192kHz/24bit PCM. The DAC uses 26mW for high performance mode, 6.6mW for low power mode, with 0.65ma low power voice activation. It can record audio at 109dB, 103dB THD+N and can fire its speaker amplifier t 4W output power. It supports Qualcomm aptX Classic and HD playback.
Qualcomm really needs to work on its naming conventions, nobody seems to care to call the chipsets as Mobile Platform, and the numbering system is quite confusing.
