Qualcomm details its Snapdragon 845 chip: 30% more efficient, fastest modem, 4K HDR video capture


As promised, the second day of Qualcomm's Tech Summit seems to be completely dedicated to the newly unveiled Snapdragon 845 processor. There's a lot of technical info about Qualcomm's most advanced chipset to date, so we'll try to simplify it for you.

First off, the Snapdragon 845 is 30% more efficient than the previous top-tier chipset, the Snapdragon 835. Also, thanks to the new graphics processing unit (GPU), the Adreno 630, the chipset offers 30% improved graphics, video rendering, and power reduction compared to the previous generation.

Qualcomm's Snapdragon 845 SoC (system-on-chip) accommodates a Kryo 385 CPU, a Hexagon 685 DSP (digital signal processor), a Spectra 280 ISP (image signal processor), AQustic Audio, as well as the company's fastest modem – the X20 Gigabit LTE radio.

The latter will be useful once US carriers like AT&T, T-Mobile and Verizon will actually fire up their Gigabit LTE-compatible networks. The modem supports speeds of up to 1.2Gbps (LTE Cat 18) and features dual SIM-dual VoLTE (voice over LTE).

Moving on to the imaging features, the Qualcomm Spectra 280 ISP enables “Ultra HD premium capture,” which means phones equipped with this chipset can record 4K HDR videos at 60fps (frames per second). Moreover, thanks to this particular ISP, users can capture HD (720p) slow-motion videos at 480fps.

Security-wise, the Snapdragon 845 supports just about any type of biometric authentication methods you can think of, such as fingerprint, iris, voice, and face.

The Kryo 385 processor features four performance cores up to 2.8GHz, which are supposed to be 25% faster than the previous generation, as well as four efficiency cores clocked at 1.8GHz. The CPU is manufactured using the 10-nanometer FinFET process technology.

Last but not least, Qualcomm's new AQustic audio codec should provide a much better wake-word recognition, as well as improved playback and record features.

According to Qualcomm, the first smartphones equipped with the Snapdragon 845 will be unveiled in early 2018. Samsung, Xiaomi, LG, HTC, and Sony may be among the first smartphone makers to adopt the new chipset.

30% more power efficiency with all these improvements and faster GPU is quite impressive.. especially since this will be on same node as S835

Finally androids are getting 4K 60fps LOL... Poor androids are always late to the much important stuff like this.

Much important stuff? Maybe 1in every 1000 needs this , no wonder you are brainwashed, get a life dude, it ain't too late.

You just trolling on every article.. It is easy to answer the same way - finally Apple get AMOLED, wireless charging, fast charging etc...? Dude, chill out and get a life. You prefer Apple, I prefer Android. So what? Cheers!

Wise reply... So many people, so many tastes... Diversity is good... Look at nature... Look at the universe...

Iphones are yet to get fast charging dude.. so you can go ahead and exclude that. The claim that the new iPhones have fast charging is stupid because you'll need to buy the expensive more powerful charger that will charge your phone a bit faster but it does the same with the iPhone 7 plus and 7 so if the new Iphones have fast charging then Iphones always had fast charging. It will still charge in over 2 hours and it will harm your Iphones battery. If iphone really had fast charging then apple would've included the fast charger in the box or wait, apple is the greediness company ever to the point that they won't even give you a fast charger and fast charging "cable" along with a 1250$ phone which also costs over 1650$ outside the us. I don't understand how people still buy iphones

in 2018, Apple would be copying I-ris scanner, higher pixel density screen, edge screen, fast wireless charging (with additional $100 or more/optional), but crappy, fragile body won't improve as they will wait for competitors to come out with a better, solid solution, so that they can copy it later on- Logic from Apple Inc.

Sounds like a good SoC. Glad they did not rush things and kept it simple once again employing Samsung to manufacture the soc since they are a leading force in the semiconductor enterprise.

There is a new L3 cache

do you know the size???? they should increase the size of their L1 and L2 first

7. Hollowmost

3 mb L2 cache for each core 2 mb L3 cache shared

"Moving on to the imaging features, the Qualcomm Spectra 280 ISP enables “Ultra HD premium capture,” which means phones equipped with this chipset can record 4K HDR videos at 60fps (frames per second). " This is why we will not see an android do 4k at 60 fps this year... 835 cant do it... although i know some SOCs can... *cough* A11 *cough* exynos *cough* Snapdragon holding everyone back

4k 60fps - capture and playback You can find it in their official sitehttps://www.qualcomm.com/products/snapdragon-845-mobile-platform

thank you for this!

Who cares about 4K at 60fps on a tiny screen? You can go ahead and mention VR/AR but that’s a niche market. VR/AR could disappear tomorrow and it would have the smallest affect on the mobile industry.

what about when i watch the video on my tv? i have a 4k tv now and i like recording in 60 fps

well it wont beat A11's score

They used to on multi-core. I doubt they will this year.

Score? on benchmark? lol.. Enjoy your useless score while android users can enjoy their faster apps performance and longer battery life. Even the SD835 is faster and last longer than A11 in youtube speedtest, this 845 will widen the gap

Lmao, were you bragging about those speed test when the Note 8 got it's ass beat by the iPhone 6s? Yeah... thought not. iOS 11 has you idiots actually believing that your s**tty midrange SoCs are actually competitive.

25% improvement won't even touch the A11 chip. Android sheep will make fun of Apple when they get an exclusive gimmick but when Apple gets the upper hand in important stuff "oh it's useless bla bla bla" LOLzz

And in all the ways that matter, the SD845 will be more than a match for the A11.

In That case, Amoled display was a Gimmick? Higher RAM was a Gimmick? Higher resolution display was a Gimmick? Multitasking was a Gimmick? Dual Camera's was a Gimmick? I mentioned all above as "Was" for a reason isn't it? :D

The source says 10nm LPP which is second gen 10 nm of Samsung foundries, not the old one. The advanced node alone provides either 10% performance gain or 15% power reduction depending on the clock speed. If I remember right new ARM Cortex-A75 alone brings 34% Geekbench 4 single core performance at same node and same clock speed. With a better node 25% performance gain is a joke. Obviously they crippled it for that semi-custom Krait sh*t. I guess they wanted it cheap, instead to making it even more powerful than stock ARM Cortex-A75, because they have no proper competition on Android ecosystem especially on high-end class. Apple will use TSMC 7nm fabs next year first for iPads then for iPhones and it offers 20% perf and 40% power efficiency over current gen 10nm TSMC which is roughly equal to current gen Samsung 10nm if not better. Its high volume production is just a couple of months behind than Samsung 10LPP. Seems to me QC have a deal with Samsung. They will be using Samsung's inferior fabs and gonna give Samsung priority over other brands.

30% more power and efficiency. I hope Nvidia takes note

Nvidia is the king at making GPU's... From low end to high end 1080 TI/XP are fastest consumer cards on market and their Volta lineup is really serious

This is not true their tegra X was powerful but consumes too much ... They will never release a competitor to adreno 540 or 630 ... By the way they quit the mobile going market

33. mikehunta727 unregistered

Their GPU's in their laptops easily can outclass Adreno 540/630 and Pascal is a extremely scalable architecture from the low end to high end and Nvidia could easily do so. Tegra X is a few years old now, Nvidia won't release a competitor or updated Tegra SoC to consumer market because of the Nintendo Switch, they have a X1 chip in there and I am sure Nintendo made them sign in the deal saying to not make another Shield Tablet or Tegra SoC for a few years You ever see Max Q laptops? They pack some ridiculous performance in a very power efficient power envelope. Nvidia is the best at making GPU's in the world

But not in mobile GPU
