Back in November, Qualcomm unveiled the name of its 2017 flagship mobile applications processor, the Snapdragon 835, and today the company has announced the key details and features of its latest mobile SoC.
At CES, we’re getting a detailed look at what’s on offer with this year’s high-end SoC. The 835 is slated to be the first ARM processor to run Windows 10, and as such, it merits a detailed look.
| Snapdragon 835 | Snapdragon 821 | Snapdragon 810 | |
|---|---|---|---|
| CPU Core | Semi-custom ARM Cortex | Kryo | ARM Cortex (ARMv8) |
| CPU Config | 4x 2.45GHz Kryo 280 4x 1.9GHz Kryo 280 |
2x 2.35GHz Kryo 2x 1.6GHz Kryo |
4x Cortex-A57 4x Cortex-A53 |
| GPU | Adreno 540 | Adreno 530 | Adreno 430 |
| DSP | Hexagon 682 with HVX | Hexagon 680 | Hexagon V56 |
| RAM | 2x 32-bit LPDDR4X 1866 MHz |
2x 32-bit LPDDR4X 1866 MHz |
2x 32-bit LPDDR4 1600 MHz |
| Flash | eMMC 5.1/ UFS 2.1 | eMMC 5.1/ UFS 2.0 | eMMC 5.0 / UFS 1.0 |
| Process | 10nm FinFET | 14nm FinFET LLP | 20nm HPm |
- The shift to 10nm means that the overall size of the Snapdragon 835 is 30% smaller than that of the Snapdragon 820 and the node shift brings improvements in energy efficiency to the tune of 40%. Qualcomm is also touting a performance increase of 27% over the previous generation.

- Here’s what’s new with the Snapdragon 835: eight Kryo 280 CPU cores, Adreno 540 GPU, DirectX 12 support, gigabit LTE modem, multi-gigabit Wi-Fi, Bluetooth 5, Hexagon 682 DSP, Spectra 180 ISP, support for HDR10 video, Quick Charge 4.0, and Qualcomm’s Aqstic codec with 32-bit/384kHz support and aptX/aptX HD Bluetooth audio.
- The Snapdragon 835 features an octa-core semi-custom CPU design, with four brand-new Kryo 280 performance cores clocked at 2.45GHz and four energy-efficient cores at 1.9GHz. The SoC will rely on the energy-efficient cluster for over 80% of the time, with the 2.45GHz cores activated for intensive use cases like VR gaming. The SoC is also compatible with LPDDR4X memory. On the GPU side, the Snapdragon 835 comes with the Adreno 540 with support for OpenGL ES 3.2, OpenCL 2.0, Vulkan, and DirectX 12.
- Battery life is one of the tentpole features of the Snapdragon 835, with Qualcomm claiming at least a day’s worth of talk time, over 5 days of music playback, more than seven hours of 4K video streaming, and over three hours of 4K video capture. To put things into context, the Snapdragon 835 consumes half as much power as the Snapdragon 801.
- The Snapdragon 835 is also the first SoC to offer Quick Charge 4.0. QC 4.0 supports USB-C and USB-PD (Power Delivery) and boasts 20% faster charging and up to 30% higher efficiency when compared to QC 3.0.
- The Snapdragon 835 also runs Qualcomm’s hardware-based Haven security platform, which has a secure execution environment for user authentication and device attestation.
