Element & Function Breakdown

7nm Course of, Kryo 485 CPU & Adreno 640 GPU

The Snapdragon 855 is Qualcomm’s first 7nm FinFET chipset, releasing on the heels of the Kirin 980 and Apple A12, the primary commercially out there 7nm cellular platforms. This isn’t a shock, provided that Qualcomm historically opts for the cutting-edge course of measurement, and that the corporate confirmed that they had been sampling their 7nm Snapdragon flagship chipset. The transfer to 7nm allows elevated transistor density whereas delivering enhancements in efficiency and energy effectivity on the order of 20% and 40% respectively, although that’s in comparison with TSMC’s personal 10nm FinFET course of. As for the Snapdragon 855’s CPU efficiency, Qualcomm states we should always anticipate efficiency enhancements of as much as 45% over the Snapdragon 845, one of many largest year-on-year efficiency bumps the corporate has put forth in current historical past.

The Qualcomm Snapdragon 855’s octa-core CPU association can also be introducing the corporate’s Kryo 485 cores clocked at 2.42GHz for the efficiency cluster and 1.8GHz for the low-power cluster. On prime of that, and as rumors had instructed, the Snapdragon 855 is introducing a ‘prime’ cluster clocked as much as 2.84Ghz. The Kryo 485 is a semi-custom core design, delivered in live performance with the system structure whereas offering some quality-of-service optimizations. The Gold cores are based mostly on ARM’s Cortex-A76 structure, which promised efficiency enhancements of as much as 35% and a 40% power-efficiency increase, whereas the Silver cores are based mostly on the Cortex A55, as seen on the Snapdragon 845. The Constructed on ARM Cortex license ought to nonetheless be fairly limiting, however the outcomes have to be promising given the figures Qualcomm offered (and how such figures have coincided with efficiency up to now). Figuring out what these cores are based mostly on ought to give us a good suggestion of what to anticipate as nicely.

We additionally discovered concerning the new Adreno 640 GPU, and what Qualcomm calls the “Snapdragon Elite Gaming Experience”, a set of options and partnerships meant to enhance cellular gaming on Snapdragon units. The corporate’s new Adreno 640 GPU stays forward of the curve by providing a wholesome 20% efficiency enchancment over the Adreno 630 present in final yr’s Snapdragon 845. Whereas the Adreno line has provided prime efficiency for a lot of generations now, it’s additionally value noting that we will anticipate the Adreno 640 to proceed main efficiency per watt as properly. With 50% extra arithmetic logic models (ALU), the Adreno 640 ought to additional speed up efficiency in AI workloads.

Qualcomm acknowledges the growing reputation of cellular gaming, notably in areas like India and China, but in addition because of the arrival of acclaimed titles like Fortnite and PlayerUnknown’s Battlegrounds. Due to this, the corporate is working intently with recreation engine builders in addition to recreation studios to ensure well-liked video games are optimized for Snapdragon units. Furthermore, Qualcomm and Unity wish to ease the transition to physically-based rendering (PBR) on cellular titles, bringing a brand new degree of realism to online game graphics. Lastly, whereas the Snapdragon 835 and Snapdragon 845 allowed playback and seize (respectively) of 10-bit, true HDR video, the Snapdragon 855 would be the first cellular chipset that permits for true HDR gaming. With the Snapdragon 675, Qualcomm launched a ‘custom algorithm’ that they claimed would scale back dropped frames in video games by as much as 90%—whereas we nonetheless don’t know far more about this function, the Snapdragon 855 will probably be implementing this as nicely. All of this coupled with Vulkan 1.1 help and the enhancements seen on the Kryo 485 ought to end in vital gaming efficiency enhancements.

Spectra 380 ISP-CV, Hexagon 690 DSP & 5G

The Spectra 380 ISP brings a number of the most essential enhancements to the Qualcomm Snapdragon 855, and the corporate is looking it the primary CV-ISP on cellular (CV standing for pc imaginative and prescient). In a media briefing, Qualcomm representatives defined that this ISP borrows from the compute models of the CPU, GPU, and DSP that assist pc imaginative and prescient duties and places them instantly on the module, to release cycles from different elements whereas growing efficiency and the quantity of obtainable horsepower. Because of the built-in, hardware-accelerated CV capabilities, the Spectra 380 can supply improved efficiency in object classification, object segmentation, and depth-sensing, whereas seeing energy financial savings of as much as 75%. Thanks to those developments, we will anticipate new options corresponding to bokeh video, in addition to the world’s first 4K HDR video seize with portrait mode or background swap, on prime of HDR10+ video seize. Images will see advantages from the improved object segmentation as nicely, enabling real-time background swaps and higher portrait mode photographs.

Whereas the corporate isn’t explicitly introducing a “neural processing unit,” AI workloads may also profit from the new-and-improved Hexagon 690 DSP, which doubled the variety of vector accelerators (HVX) from two to 4 to work in tandem with the 4 scalar threads. On prime of that, the Hexagon 690 brings the primary tensor accelerator for cellular with the Hexagon Tensor Accelerator (HTA). Enhancements to the DSP ought to translate into improved voice assistant efficiency from hotword detection to on-device command parsing, providing improved echo cancellation and noise suppression, for instance. Qualcomm stresses that they supply an entire heterogeneous compute platform that permits AI workload to faucet into both the CPU, GPU, or DSP, or any mixture of the three blocks. The “Qualcomm AI Engine” goes past hardware too, as we additionally discover help for the Snapdragon Neural Processing SDK and Hexagon NN to entry the aforementioned blocks, in addition to the Android NN API, and widespread ML frameworks corresponding to Caffe/Caffe 2, TensorFlow/Lite, and ONNX (Open Neural Community Change). To study extra concerning the Hexagon DSP, take a look at final yr’s piece detailing the way it helps with AI workloads.

Lastly, in relation to connectivity, the Snapdragon 855 is Qualcomm’s “Gigabit everything” chipset. The Snapdragon 855 packs the world’s first Wi-Fi6 11ax-ready cellular answer, with options like eight×eight sounding to serve extra units effectively, the newest safety with WPA3, and as much as 67% higher energy effectivity. What’s extra, it’s additionally 60Ghz Wi-Fi-capable, with the 802.11ay-based platform taking Wi-Fi speeds as much as 10Gbps in addition to even decrease latency. As anticipated from a brand new Qualcomm chipset, the Snapdragon 855 improved knowledge connection speeds of as much as 2Gbps Cat 20 LTE with the Snapdragon X24 LTE modem. The Snapdragon X24 modem thus delivers twice the height obtain velocity of the previous-generation LTE modem by way of four×four MIMO on 5 aggregated LTE carriers and offers help of Cat 20 add speeds of as much as 316 Mbps. On prime of that, OEMs will be capable of additionally go for the Snapdragon X50 5G modem, with help for sub-6GHz and mmWave frequency bands, for as much as 5Gbps obtain speeds with unprecedented latency. Qualcomm claims that within the mmWave frequency band, customers can anticipate as much as 20x quicker common efficiency in comparison with present business options. In fact, the latter won’t make a lot of an impression on the time of launch given the speed of deployment of 5G networks. Verizon has had a restricted rollout of 5G throughout 4 cities (with restricted obtain speeds of about 300Mbps), for instance, however the world at giant should wait a bit longer to make use of those connectivity enhancements. To study extra concerning the plans for 5G deployment in 2019, take a look at our piece from yesterday.

As regular, you possibly can anticipate the Snapdragon 855 to be featured in 2019’s most prolific units—particularly given Qualcomm’s benefit in 5G connectivity, and a number of OEMs having teased or introduced 5G-enabled units for subsequent yr. The 2018 Snapdragon Tech Summit is way from over, and there’s nonetheless much more to study concerning the Qualcomm Snapdragon 855. Take a look at our extra in-depth article on the newest modifications to the Snapdragon 855 right here. For extra info, keep tuned to XDA-Builders, as we’ll have much more Snapdragon 855 information and content material all through the week.
