QualcommSoC1

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

The Snapdragon 835 will characteristic the Kryo 280 core and will have viii cores in total in a big.Piddling configuration. The college-end cores will run at up to 2.45GHz, while the "little" cores are clocked at 1.8GHz max. It will feature LPDRR4X (a type of LPDDR4 developed by Samsung that uses 0.6V for I/O voltage (Vddq) rather than the standard ane.1V. Qualcomm has shrunk the overall package by 35% while claiming a 20% performance proceeds, and 25% faster graphics rendering.

It looks as if much of the improved functioning is delivered courtesy of clock speed gains rather than whatever major microarchitectural changes. It's a well-known fact that smartphones rarely run at their elevation frequencies for any length of fourth dimension due to aggressive power management. If the 10nm scrap tin hold college clock speeds than its 14nm predecessor, it tin deliver better performance as a result. One reason why these gains frequently neglect to event in visible performance improvements is because thermal and power envelopes limit their applicability to specific applications or workloads, and considering efficiency improvements accept naturally diminishing returns. For example, if it takes 2W to play a video and a new telephone takes 1W to play the aforementioned video, that'll have a very noticeable impact on battery life. If it takes 0.8W to play a video and improving applied science cuts that to 0.4W, y'all're still getting a benefit — but the objective visibility of that benefit is reduced.

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

  • Snapdragon X16 LTE Modem (Category xvi LTE) with Category 13 LTE upload speeds
  • Back up for 802.11ad Wi-Fi
  • Bluetooth 5.0 back up (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 signal processor, no details given on this upgrade)

Snapdragon 835 will also feature Qualcomm'southward QuickCharge 4.0, which promises total USB-C compatibility while however charging 20% faster than the not-USB-C compatible QC3.0, and significant improvements in battery life. The device besides supports Qualcomm'due south All-Means Enlightened engineering and Google'south Sensation API, just in case you experience comfortable having a device explicitly designed to spy on y'all at all times. Given the popularity of Amazon's Echo, too as digital data skimmers similar Siri and Cortana, I accept no doubtfulness millions of Americans will queue for the privilege of transmitting personal information to corporations with nil accountability or disclosure on how that data is used, sold, or combined with information from third parties. Given ongoing research into how Facebook buys 3rd-party data to combine with other information you tell it about your use of the service, the utter lack of security in the IoT universe, and the way corporations that run into fiscal trouble all of a sudden discover they can sell their customer databases, I wouldn't touch these technologies with a ten-human foot pole. We're exposed enough already. But that'due south my personal stance, not an ExtremeTech stance.

Qualcomm is billing the Snapdragon 835 as a fleck that'll deliver ameliorate VR, amend 4K experiences, better battery life, and superior overall functioning, with the start devices expected to send this spring. We shall accept to wait and see how things pan out — Qualcomm's Snapdragon 820 has been well received, simply the previous Snapdragon 810 suffered from poor OEM optimizations and the resulting increased oestrus and lower battery life that comes along with imperfect large.Little support in software. Hopefully the Snapdragon 835 has better purchase-in from customers and more work has been washed to make information technology easier to implement power modes.
