By way of capabilities, Qualcomm says that the GPU is 35 p.c quicker than earlier than, that the AI chip has 1000x decrease latency and sees a efficiency bump from 15 TOPS to 26, and that the brand new triple ISP system helps bigger photographs and 4K HDR on three cameras concurrently.

The model new X60 modem is now built-in — it was a discrete unit on the 865 — which ought to end in some enhancements to effectivity and energy consumption.

In sum, that is the biggest year-on-year efficiency bump that Qualcomm has ever supplied.

Right here’s a fast overview of the chip:

CPU: New cores and a design that focuses on sustained efficiency

The SD888 sticks with the triple cluster configuration, that includes one excessive efficiency core, three efficiency cores, and 4 effectivity cores. This time round, the excessive efficiency ‘Prime’ core is the newest Cortex X1 clocked at 2.84 GHz. This core may be clocked to just a little over 3 GHz, however Qualcomm says it caught with 2.84 GHz in order to supply higher sustained efficiency beneath heavy workloads.

The efficiency cores additionally see an improve to the brand new Cortex A78 core (from final yr’s A77), however are nonetheless clocked at 2.42 GHz for the explanations acknowledged above.

Do notice that the 865+ featured a Prime core clocked at 3.09 GHz — vs 2.84 GHz on the common 865 — so it might be secure to imagine that an overclocked 888+ variant will arrive later subsequent yr.

The third cluster of 4x Cortex A55 cores seems to have been carried ahead as is from final yr.

General CPU efficiency has improved by about 25 p.c, says Qualcomm, with the main target being on higher sustained efficiency moderately than peak efficiency.

GPU: 35 p.c quicker and VRS help

Qualcomm’s secret sauce has all the time been its GPU and DSP (extra on that in a bit). Whereas Samsung and Huawei most popular off-the-shelf ARM designs prior to now, Qualcomm has, for some time now, been designing its personal GPU and DSP chips.

We don’t know a lot concerning the inside workings of the brand new Adreno 660 GPU, however Qualcomm did point out that it’s now about 35 p.c quicker and 20 p.c extra environment friendly than final yr’s Adreno 650, and that the GPU now helps VRS or variable price shading.

VRS is a function that’s solely lately arrived to PC graphics playing cards and sport consoles. VRS basically permits for a scene in a sport to render quicker by spending much less effort and time rendering parts of the scene that may not be important to the participant anyway. For instance, areas beneath deep shadow or within the distance needn’t be rendered with as a lot texture element and color accuracy as areas which might be nearer to the participant.

On condition that the SD865 might already help 120 fps and 144 fps gaming, this bump in graphics efficiency may very well be used to considerably enhance the standard of in-game graphics.

Different options like QuickTouch assist enhance contact response, additional enhancing the gaming expertise.

Hexagon DSP: Massively improved AI efficiency

Now that is one thing Qualcomm was very excited to speak about. The Snapdragon 888 options ‘fused AI accelerators’.

Primarily, earlier iterations of the Hexagon DSP (digital sign processor) featured separate scalar, vector, and tensor accelerators — cores that carry out particular mathematical operations wanted for AI calculations. Every accelerator had its personal reminiscence and a pool of shared reminiscence, and the system did work very nicely, giving Qualcomm a big lead in AI efficiency in comparison with rivals.

This yr, Qualcomm fully redesigned the DSP and ‘fused’ the capabilities of the three accelerators. The outcome, based on Qualcomm, is a big enchancment in AI efficiency. This improved AI engine communicates 1000x (sure, one thousand occasions) quicker than earlier than, whereas consuming much less energy and almost doubling efficiency in sure AI workloads.

Different updates comparable to a wider reminiscence bus and reminiscence pool have additionally helped.

General, efficiency has gone up a claimed 73 p.c in comparison with final yr’s 865.

The updates to AI efficiency are, sadly, just a little more durable to grasp within the real-world. What are tensor operations, for instance, and the way do they matter?

Effectively, enhancements in AI efficiency imply that clever computing options like clever noise suppression (audio and video), real-time object substitute in video, AI-based autofocus, quicker picture processing, and extra can now be a actuality for Android.

Digicam upgrades: Staggered HDR and concurrent recordings

By far probably the most fascinating bit of reports from the occasion was the point out of staggered HDR help for stills and video.

Earlier than we get to that, let’s first check out the {hardware} upgrades. Primarily, the SD 888 bumps up the overall variety of ISPs to 3. An ISP or picture sign processor is the chip that’s liable for processing imaging information from a telephone’s cameras. With three impartial ISPs (up from two within the 865), Snapdragon 888-powered telephones can now, lastly, seize photographs and video from three cameras concurrently. Apple launched this function final yr with the iPhone 11 Professional line.

The ISPs now permit for concurrent 28 MP ZSL seize (zero shutter lag). Single digicam ZSL seize has been bumped as much as 84 MP (from 64 MP), and 200 MP single picture captures with out ZSL are supported.

ZSL is just Qualcomm’s time period for a picture seize mechanism the place the sensor actively data information earlier than a shutter press, guaranteeing that picture information is recorded the moment the shutter is pressed, and never after the very fact.

Triple digicam ZSL seize means you’ll be able to have stitched photographs and seamless zoom between, say, an ultra-wide, vast, and tele lens (as Apple has been doing since 2019).

The digicam system now permits the seize of 120 12 MP photographs per second, and autofocus in low mild (as much as 0.1 lux).

Video recording options stay largely unchanged, with 8K 30 fps and 4K 120 fps with HDR being the very best supported resolutions.

A brand new AI-based autofocus system claims to enhance AF efficiency by intelligently figuring out the topic in a scene and monitoring focus appropriately.

Essentially the most fascinating improve, although, is help for staggered HDR.

HDR picture/video seize occurs when a number of completely different exposures are captured and stitched collectively, leading to a picture with extra dynamic vary (larger element in vivid and darkish areas) than a single picture would have had.

In common HDR, the digicam shutter captures at the very least three distinct frames: one underexposed body, one overexposed body, and one correctly uncovered body. New telephones do seize much more frames, nevertheless, however the level is that every body is captured as a complete, one full body at a time. Recording for the subsequent body doesn’t begin till the earlier body has been recorded and processed.

That is very efficient for static objects, however when a scene includes transferring objects (canines, vehicles, windy climate), there may be some ghosting and blur due to the time it takes to seize particular person frames.

Staggered HDR reduces this lag by not ready for a person body to be captured. As and when every line of the sensor is learn for one body, seize for the next body begins on that line. HDR information is recorded repeatedly, leading to a lot much less lag between frames, and thus much less movement blur and ghosting.

X60 Modem: Built-in, quicker, extra environment friendly

Final yr’s SD865 didn’t embody an built-in modem. Qualcomm had their very own reasoning for this, and acknowledged that the modem was developed independently and was prepared earlier than the 865 was, permitting producers to work on their 5G implementations. Regardless, now that the x60 is built-in into the 888, this could end in decrease costs and higher efficiency and energy effectivity. Precisely how a lot of a profit that is nonetheless stays to be seen, nevertheless.

The x60 can be claimed to be quicker and extra environment friendly than the x50, providing a lot decrease energy consumption in edge instances, and provides higher help for provider aggregation, leading to a lot greater sign high quality and bandwidth.

Moreover, the platform helps WiFi 6, WiFi 6E, and twin radio Bluetooth 5.2 and AptX Adaptive wi-fi audio.

Misc options: Hypervisors, CAI

An essential function of the Snapdragon 888 is help for hypervisors. A hypervisor is a system for isolating one person house from one other, creating a number of safe digital machines.

In plain English, the hypervisor will permit for, say, a safe work profile in your telephone that may perform independently of your private profile. Knowledge from the 2 profiles can be independently and securely dealt with. The hypervisor can be used to fully isolate delicate apps from the remainder of the system.

SD 888 now additionally helps the CAI or Content material Authenticity Initiative normal. Any picture you seize through this technique accommodates a cryptographic key that verifies the authenticity of the metadata (location, time of seize, and so forth.) and that the picture hasn’t been manipulated. Any modification modifications the important thing and flags the picture as having been manipulated.

On this world of deep fakes and manipulated photographs, a CAI-stamped picture is extra more likely to be trusted.

Calling all devs!

Pending real-world checks and benchmarks, Qualcomm seems to have surpassed itself this time round. The SD 888 platform is a big improve over final yr’s 865, and introduces quite a lot of thrilling new options besides.

It’s a very spectacular improve and I’m fairly excited to see what 2021’s Android flagships have in retailer for us. I simply hope builders take full benefit of the capabilities afforded to them by the brand new platform.
