Qualcomm unveils Snapdragon 670 Mobile Platform; What’s new?

Qualcomm has been filling up the gaps on their product portfolio, with the 700 series announced earlier this year. The first of the 7xxs, the Snapdragon 710 is seen as an upgrade from last year’s Snapdragon 660. What makes it more special though is it’s close spec sheet to the high-end 800 series. For that reason alone, manufacturers prefer it (and even the older Snapdragon 660) over the more recent Snapdragon 632. The Snapdragon 632, while features some upgrades over the 660, has failed to impress a number of OEMs. Today, Qualcomm announced a new chipset under the 600 series, which is more deserving as the 660’s successor.

The new Snapdragon 670 is built on 10nm LPP process technology, making it on par with the Snapdragon 710. Last year’s Snapdragon 66o was built on 14nm fabrication, and that alone shows a huge difference.  This is also the first chipset under the 600 series to use a Kryo 360 CPU, which is a semi-custom core design delivered to collaborate with the system architecture while also providing some service optimization.

The two Kryo 360 A75-based Gold (performance) cores are clocked at 2.0GHz, while the six A55-based Silver (efficiency) cores are clocked up to 1.7GHz. According to Qualcomm, we should expect up to 15% higher performance gain over the Snapdragon 660’ 4+4 Kryo 260 setup.

For the graphics, the Snapdragon 670 utilizes the new Adreno 615, which Qualcomm claims can offer up to 25% faster graphics rendering over the Adreno 512 on the Snapdragon 660. It can also power up to FHD+ resolution displays, with support for Ultra HD video playback. There is also a support for Open GL ES 3.2, Open CL 2.0 as well as Vulkan graphics. Qualcomm again stresses that GPU can aid AI workloads, and heterogeneous compute-cases.

The new chipset also comes in a bundle with the powerful Hexagon 685 DSP. This is the same DSP found on both the Snapdragon 710 and 845. It’ll help AI workloads by delivering great compute capabilities at lower power consumption. Qualcomm claims that the chipset’s AI Engine (a collaborative effort of DSP, GPU, and CPU), can output 1.8x the AI performance on the Snapdragon 660.

For the imaging, the new Snapdragon 670 uses the same Spectra 250 ISP from the Snapdragon 710, which can support a single 25MP camera or two 16MP cameras. Features include improved stabilization, active depth-sensing, multi-frame noise-reduction, and super-resolution. It can also support slow-motion video capture, and 4K video recording (up to 30fps), at 30% lower power consumption over the Snapdragon 660.

Other features include 802.11ac 2×2 Wi-Fi, Bluetooth 5, and the Snapdragon X12 LTE modem for 600Mbps downlink, and 150Mbps uplink. It can also support up to 8GB of LPDDR4x RAM (2×16-bit, up to 1866MHz). Well, I think that’s too overkill for a midrange but at least it’s there. There will also be Quick Charge 4+ for faster-charging speeds.
