Rumored Snapdragon 845 SoC to include X20 modem chip capable of 1.2Gbps downlink speed

Rumored Snapdragon 845 SoC to include X20 modem chip capable of 1.2Gbps downlink speed
Last month, we passed along a report stating that the Snapdragon 845 chipset will be Qualcomm's next high-end SoC, and will power the next-generation of high-end handsets. While the Samsung Galaxy S8 and Samsung Galaxy S8+ got first crack this year at selling handsets powered by the top-shelf Snapdragon 835 chipset (leaving the LG G6 to rely on the Snapdragon 821 SoC), the early reports suggest that LG and Qualcomm have already engaged in talks that would guarantee the presence of the Snapdragon 845 chipset on the LG G7.

According to a profile of a Qualcomm Senior Staff Engineer that was discovered yesterday on LinkedIn, the chip maker is working on including the zippy X20 modem with the Snapdragon 845 chipset. The modem supports LTE Cat. 18, which means that it can run at download speeds as fast as 1.2 Gbps. It is built on the 10nm FinFET process, and thanks to the use of 2x20MHz carrier aggregation (which widens the network pipeline allowing more traffic to flow freely), upload speeds will be as high as 150Mbps.

Qualcomm says that the X20 has been designed with 5G in mind and hopes that the modem will help move forward the use of 5G technology. Several manufacturers received samples of the X20 modem earlier this year, which means that the chip will be commercialized in 2018 when the new range of Snapdragon 845 powered handsets is released.

But how will it affect battery life? I would like a processor that has the latest tech while being battery efficient like the SD625.

Post 3. Try the 835 in the S8...simply awesome.

Underclock your phone to 1.8 GHz. If your phone has 6 or 8 cores, no need to have more than 1.8GHz. My tablet has sd400. I play RR3 on it. Only difference is lower quality, not big deal to me, do not care. But it does not lag.

@post #14 Under clocking the CPU requires root, though... And it is becoming harder and harder to root newer phones these days.

OEMs can underclock your phone without root. SO there is a way.

I can't wait until 2030 when I can take advantage of that speed.

On a phone tbat will cost more and do less. Please be inba burry cor ypur app to crash. Or maybe it will just stop working. The fact that may phone does way mofe than yours, and is just as fast is good enough for me. I get to do what i want, whenever i want and its awesome. Just understand the iPhone isnt for everyone. The problem with all of Apple stupid fanboys, want to argue at being better vs us following tbeir own msrketing ads of Think Different. Why does it have to be about stupid nothing with you guys.

I'm just stating that right now the fastest 4G I've ever used was 40mb/s double speed on EE so do we really need to play the numbers game with this? At this rate when we finally achieve those speeds on a mobile network we'll have modems that can do 50,000mb/s. But for some reason you had to make it about iPhones when nobody even mentioned that.

There is no benefit at the moment and for next decade to put X20 modem. Rather they should focus on matching apple in CPU and GPU performance.

Qualcomm's GPU performance is already ahead of Apple's Especially in sustained GPU performance where they lead even ARM/Samsung Single core CPU performance is where they are behind But then the real world difference isn't really noticeable I'd prefer if they continue focusing on efficiency, sustained performance, DSPs, and camera tech

Adreno 540 doesn't seem to be ahead of the a10's GPU, not to mention it throttles faster tested by multiple sources, videos available on YouTube.

The 540 wins in GFXBench and 3DMark The A10's wins in Basemark, but that's OpenGL ES 3.1 vs Metal, wait for their Vulkan version later this year for a proper comparison Even the 820's GPU throttles less than A10's GPU OnePlus 3 (1080p)http://images.anandtech.com/doci/10411/ProperstabilityOP3%20copy.png Almost maintains 30 fps for the whole thing iPhone 7 Plus (1080p)http://images.anandtech.com/doci/10685/Manhattan_Rundown_7Plus.png Drops to ~25 fps within 15mins or so The reason the A10's GPU beat the 820's in short benchmarks is because the 820's is underclocked for better sustained performance (as is the 835)

The A10 cpu from 2016 will still probably leave it in the dust tbh..

Did you check PhoneBuff's recent video in which the iPhone 6S defeated the S8 in a speed test? It's unexpected.

BUT IPHONE IS FASTER ONLY LAUNCHING GAMEShttps://m.youtube.com/watch?v=BKLS_h1mIpM

This is a reply to no.21 Yeah, and it's the fastest in launching the heavier games. And that's because they are CPU/GPU intensive; an area where the iPhone 6S excels. Not only that. The iPhone 7 is also fastest in other CPU intensive tasks such as creating a time lapse. The 6S is just about as fast as the S8 in this regard. Apple's A series chips are excellent in terms of mobile CPU and GPU performance, especially the A10. It's another thing that the A10's GPU isn't as good in sustaining performance as an Adreno 530. But that's a different topic for debate.

It holds more apps open than other most other devices and also finishes heavy tasks a lot faster(things like time lapse, converting videos to 1080p/+) 6S/A9 is even faster than 835 in many tasks

The XZ Premium beat the iPhone 7 plus in opening games too. Check out phone battle's speed test.

Reply to post 31 - I started watching for maybe 2 minutes into the tests. Here are logical good reasons why ALL speed tests are stupid: 1 - The chances someones phone is setup exactly the way it is in the test in the video is 1 in 3Billion - Which means the only phone to be setup that way, is the phone in the video 2 - YouTubers cherry pick apps that may or may not perform well on a platform they like or hate. 3 - If you put 2 exact same phones side by side and did the same tests, they still own't work 100% identical. 4 - No one uses a phone by opening an app, closing the app, opening another app and closing over and over and over in such a fashion. 5 - ALL OF THE ABOVE IOS device apps have direct hardware access vs apps on Android that don't. Perception says this is suppose to be beneficial, but in reality, its not.

Phonebuff is a douche and added that multi tasking bs that an IOS device will always win. And he wonders why Samsung stopped letting him test things early.

The iPhone 7s with Intel modems are only capable of 0.450Gbps The ones with Qualcomm modems are capable of 0.6Gbps but handicapped to 0.450Gbps for parity with Intel's)

Yes you are absolutely right, but I am talking about CPU and GPU performance only :) Not comparing the Modems.
