QualcommSoC1

Late last year, Qualcomm announced the Snapdragon 835 would be its adjacent-generation smartphone SoC. The new chip is built on a 10nm process in partnership with Samsung, but Qualcomm hadn't unveiled much in the way of additional details. This calendar week at CES, the company shared new details on the upcoming chip, including clock speeds, core designs, and upgrades over and above the Snapdragon 820.

The Snapdragon 835 volition feature the Kryo 280 core and will accept eight cores in total in a large.Little configuration. The college-cease cores will run at up to 2.45GHz, while the "piffling" cores are clocked at one.8GHz max. Information technology will feature LPDRR4X (a type of LPDDR4 developed by Samsung that uses 0.6V for I/O voltage (Vddq) rather than the standard 1.1V. Qualcomm has shrunk the overall package past 35% while claiming a 20% performance gain, and 25% faster graphics rendering.

Information technology looks as if much of the improved performance is delivered courtesy of clock speed gains rather than whatever major microarchitectural changes. It'south a well-known fact that smartphones rarely run at their meridian frequencies for any length of time due to aggressive power management. If the 10nm flake can hold higher clock speeds than its 14nm predecessor, information technology tin can deliver better performance as a consequence. I reason why these gains often fail to result in visible functioning improvements is because thermal and power envelopes limit their applicability to specific applications or workloads, and because efficiency improvements have naturally diminishing returns. For example, if it takes 2W to play a video and a new phone takes 1W to play the same video, that'll have a very noticeable bear on on battery life. If it takes 0.8W to play a video and improving engineering cuts that to 0.4W, you're however getting a do good — merely the objective visibility of that benefit is reduced.

Here's a listing of the Snapdragon 835'south other features.

  • Snapdragon X16 LTE Modem (Category 16 LTE) with Category 13 LTE upload speeds
  • Support for 802.11ad Wi-Fi
  • Bluetooth 5.0 support (Bluetooth five is expected to double the speed of Bluetooth 4.2 while increasing its range)
  • Adreno 540 graphics (25% improved rendering predicted, no details given)
  • Hexagon 682 DSP (The Snapdragon 820 had a Hexagon 680 digital point processor, no details given on this upgrade)

Snapdragon 835 will also feature Qualcomm's QuickCharge 4.0, which promises full USB-C compatibility while still charging 20% faster than the non-USB-C compatible QC3.0, and meaning improvements in bombardment life. The device also supports Qualcomm's All-Means Aware technology and Google's Awareness API, merely in instance you feel comfortable having a device explicitly designed to spy on you at all times. Given the popularity of Amazon's Echo, as well as digital information skimmers like Siri and Cortana, I have no doubtfulness millions of Americans volition queue for the privilege of transmitting personal data to corporations with zero accountability or disclosure on how that data is used, sold, or combined with information from third parties. Given ongoing research into how Facebook buys third-party information to combine with other information you tell it nearly your use of the service, the utter lack of security in the IoT universe, and the fashion corporations that run into financial trouble suddenly discover they can sell their customer databases, I wouldn't touch these technologies with a 10-foot pole. We're exposed enough already. But that's my personal stance, non an ExtremeTech stance.

Qualcomm is billing the Snapdragon 835 as a flake that'll evangelize better VR, better 4K experiences, better battery life, and superior overall operation, with the showtime devices expected to ship this spring. We shall have to await and see how things pan out — Qualcomm's Snapdragon 820 has been well received, but the previous Snapdragon 810 suffered from poor OEM optimizations and the resulting increased estrus and lower bombardment life that comes along with imperfect big.Little support in software. Hopefully the Snapdragon 835 has better buy-in from customers and more than work has been done to brand it easier to implement power modes.
