Qualcomm Launches Snapdragon 820

Qualcomm wants we to know a new Snapdragon 820 processor is unequivocally cool.

That’s a joke, of course, given this year’s Snapdragon 810 indication struggled with thermal play that overshadowed a performance. With a high-end lineup that captivated middling-at-best reviews, Qualcomm mislaid one of a biggest high-end processor business as a Samsung Galaxy S6 switched to an all-Samsung processor lineup.

The association has been dribbling out information on a new 820 chip given August, yet finally brought it all together during a launch eventuality currently in New York. The 820 goes behind to Qualcomm’s strengths, with power-efficient, tradition new Kryo cores that are firmly integrated with a world’s best modem and what Qualcomm says is a strikingly improved GPU than before.

“Is it thermally efficient? Does it broach some-more battery life? The answer to all of these things is positively yes,” pronounced Tim McDonough, Qualcomm’s CMO.

Qualcomm Bets on VR
McDonough and Qualcomm boss Derek Aberle pronounced that a 820 is designed to capacitate “immersive” VR and protracted existence experiences. That means 4K displays, really tighten to your face, with approximate sound and evident response to sensor submit like relocating your head, McDonough said.

“Virtual existence resets a requirements. The visible peculiarity needs to be so good that it tricks we into meditative it’s real,” he said.

No loyal VR practice were being demoed today, though. The top fortitude rendered demos we saw were 720p, good brief of VR quality. That’s given high-quality VR takes a lot some-more than a chip—it takes OS, audio, and arrangement components that Qualcomm wasn’t prepared to put together into a demo device, pronounced Keith Kressin, Qualcomm’s VP of corporate development.

“We consider we’re well-positioned with a best chip in a industry, yet we thought, that’s not a right form factor, venue or time. We’d rather wait until we have something that can emanate a wow,” he said.

Core Wars: Apple Was Right
One of this year’s large chip controversies was possibly chips with a few fit cores outperform chips with many, yet potentially slower cores. Apple was a categorical proponent of a initial position, as a dual-core A9 processor has really high single-core performance. On a other side, we had Mediatek, Samsung, and Qualcomm all compelling an octo-core approach.

The Snapdragon 820 drops behind down to customarily regulating usually dual cores during a time. It has 4 cores total, dual higher-power and dual lower-power.

“There’s really small justification that OSes can take advantage of some-more than dual or 3 cores,” pronounced Travis Lanier, comparison executive for product government during Qualcomm. “I still trust there’s a lot of gas as distant as single-thread performance.”

The new Kryo core formula in double a opening on single-thread tasks as compared to this year’s Snapdragon 810, Lanier said. The 820 also wraps a CPU adult in a “heterogeneous computing” gold that relies on a GPU and DSP chips for many tasks, execs said. That creates particular CPU opening reduction vicious than altogether chip performance, they said.

So what was going on final year with all a cores? At a high end, Qualcomm was regulating ARM’s customary Big.Little setup, Lanier said. In lower-end phones, manufacturers are perfectionist some-more cores to fill out their selling spec sheets.

“When we get to reduce tier chips, specs start to rule,” Kressin said. “If we have a $100 handset and one man has 4 cores and one man has 8 cores, there’s a selling angle.”

Call Quality Is Back Again

Qualcomm demoed a garland of Snapdragon 820 features, yet many of them seemed flattering incremental—better low-light video here, improved surround-sound there. The facilities that jumped out during me had to do with connectivity.

The Snapdragon 820 has new Wi-Fi job record that is many improved during handing behind and onward between Wi-Fi and cellular, expelling hilly Wi-Fi calls. Its TruSignal technology, initial seen on a existent LG V10, boosts mobile vigilance and so call peculiarity by bettering receiver use to a approach you’re holding a phone. we saw it in a demo, and it done a thespian disproportion to call quality.

The X12 modem supports LTE speeds adult to 600Mbps, with uploads adult to 150Mbps. That requires some-more spectrum than many carriers have. But it also has 60GHz Wi-Fi 802.11ad, that enables record send within homes during gigabit speeds, relocating TV shows from your DVR to your phone in seconds. It has LTE-U, that ATT, T-Mobile, and Verizon will all be regulating to boost speeds and ability by pulling LTE over Wi-Fi spectrum.

The outcome of all of this will be phones that make clearer calls and adjust many some-more fast to whatever a fastest network is around them.

The Snapdragon 820 will seem in phones during a initial half of subsequent year. we strongly think we’ll initial see it possibly in an LG phone launched during CES in January, or in inclination launched during Mobile World Congress in mid-February.
