Hexagon 680 DSP will help take a load off of the main CPU of the Snapdragon 820 chipset

Hexagon 680 DSP will help take a load off of the main CPU of the Snapdragon 820 chipset
On Monday, Qualcomm spoke at the Hot Chips conference about a major component of the upcoming Snapdragon 820 chipset. The Hexagon 680 Digital Signal Processor will be part of the new top-shelf SoC, taking some of the heavy load off of the main processor, allowing it to use less power and save battery life.

There are three parts to the Hexagon 680. One part helps the chip process audio, voice, images, and video. It helps brighten dark areas of photographs and videos by using algorithms. It also reduces battery consumption during image and video processing. The DSP will help improve the performance of both virtual reality and augmented reality apps.

The second part of the DSP helps provide energy to low-power using sensors, and powers always-on features like voice recognition. Not only does this help extend the battery life of a Snapdragon 820 powered device, it also takes work away from the main CPU. The third and last part of this DSP is a modem which handles multimode, carrier aggregation and global LTE connectivity.

The Snapdragon 820 is expected to start showing up in new handsets during the first quarter of 2016. The first phone expected to be powered by it is the Xiaomi Mi 5. Coming off the overheating experience with the Snapdragon 810 SoC, all eyes will be on the Snapdragon 820 chip to see if it has any heating issues.

Thanks for the tip!

Will Qualcomm be around for 2016?

It's not Qualcomm but HTC I'm worried about for 2016. Even though the SD 810 screwed many OEM's they still have a pretty big presence with low to mid range devices. And look at the Nexus hump back. They have no choice but to use Qualcomm.

2016? Sure. 2017 in the chip game? Probably, but not used by much or they will have to reduce prices. I can clearly see a day where Qualcomm lives exclusively from the patents. On HTC though, I think it all depends on how they play out their hand with Mid Range / High end in 2016... M8 sales are still kicking in even in 2015... They just need to make sure they make the next One device available in more carriers and actually give a decent reason to upgrade..

SD820 will be a beast, and everyone will want some of it. The 810 was an unfortunate hiccup, not a career ending fault.

Qualcomm needs to keep one eye on the big elephant in the room, INTEL. They have slowly been turning their attention to mobile and have the resources and know how to take it over if they want.

Hocus Pocus... too little too late? I wouldn't expect the big 4 OEM's (Samsung, Sony, LG & HTC) to be jumping at this chipset for upcoming flagships after the 810 debacle..

Think twice, after a big mistake like qc and the loss they made (big profit losses), a company like QC will make a very strong comeback. They have to win their trust back. But it is good to stay skeptical. Never be brand loyal no matter what.

Qc sd 810 *

I mean, QC did make a big deal about the 810, and look how that turned out. If they keep doing the same with the 820 and it turns into a flop, all OEMs will go elsewhere for the SoCs.

Probably switching to Intel/Mediatek or LG if they do go ahead with their plans. Exynos won't happen much until it becomes an open platform because of the ROM development.

Here's to Qualcomm cleaning up the huge stain it had because of the sd810 aka oven maker

Qualomm's near future depends on Samsung's acceptance of 820. If they do not use it for S7, Qualcomm is going to be in trouble in 2016 also.

I really doubt Qualcomm were sitting with their thumbs up their behinds this whole year. They know they can't survive relying on Samsung and have optimized for that.

Samsung will use whatever is the best for North America. If the SD820 is great enough, they will buy. If not they won't. Keep in mind that the Exynos was only ever used in North American markets for the Galaxy S and Galaxy S6. The Exynos was also used in the T-Mobile and Bell GS2 but the rest of the GS2 models used the Qualcomm S3 scorpion. So that's actually a pretty decent track record that Samsung bought the rest. Although I would be pretty choked if those Mongoose benchmarks were real and we got the SD820 and everyone else got the Mongoose cores. Lol

the galaxy note 2 used an exynos 4 in north america as well

I believe that Qualcomm has the talent to pull off something great with the 820. However, all talk is cheap until there are actual phones on the market being tested with this soc inside.

Indeed. It all comes down ro see what they got in store for 2016. But one thing for sure, this is a decisive year for them after the 810 fiasco... Plus, gave a lot of space to Mediatek evolve in the process.

Snapdragon promise better battery efficiency and improved performance everytime they announce a new processor. Just look at SD810 and SD6xx

Qualcomm lied to everyone saying the 810 did not overheat. They cannot be trusted!

Read: we were unable to control the overheating of this chip, so we have added another chip to do the work, and we hope *crosses fingers* that it keeps the temps down.
