Qualcomm’s Snapdragon 855 is official, coming to Android flagships in 2019

Qualcomm has introduced its flagship System on a Chip (SoC) for 2019: the Snapdragon 855. As Qualcomm has principally no competitors on the high-end SoC market—particularly within the US—the Snapdragon 855 might be headed to virtually each flagship Android cellphone that ships in 2019. In comparison with 2018’s chip, the Snapdragon 845, Qualcomm is promising a 45-percent quicker CPU, a 20-percent quicker GPU, and a platform that can usher within the period of 5G connectivity.

So how is the Snapdragon 855 totally different from its predecessor, the Snapdragon 845? First, we’re getting smaller transistors. The Snapdragon 845 was constructed on Samsung’s 10nm semiconductor manufacturing course of, however the 855 is shifting to TSMC’s 7nm course of. A smaller manufacturing course of comes with the advantage of decrease energy consumption and smaller chips, and the 7nm node places the Snapdragon 855 on par with Apple, which shipped the 7nm A12 Bionic SoC in the iPhone XS earlier this yr.

The Snapdragon 845 CPU was branded “Kryo 385” and had 4 2.7Ghz Cortex A75-based cores and 4 1.8GHz Cortex A55-based cores. These two CPU clusters break up the CPU into “large” and “little” workloads, the place 4 larger, extra power-hungry cores dealt with heavier processing duties like foreground apps (the A75 cores) and 4 slower, lower-power cores dealt with background duties and idle processing (the A55 cores).

The Snapdragon 855 remains to be sort of constructed with this 4+Four core format, however now one of many large cores has a boosted clock charge. So the brand new Snapdragon 855 CPU is branded “Kryo 485” and modifications to 4 newer Cortex A76-based cores for the “large” cluster, with three cores clocked at 2.42GHz and one clocked at 2.84GHz. Qualcomm is looking this boosted core the “Prime Core.” The smaller core cluster makes use of the identical 4 1.8GHz Cortex A55-based cores because the older chip.

The GPU modifications from the 845’s Adreno 630 to an Adreno 640 GPU within the 855. Aside from promising it is going to be 20-percent quicker and include Vulkan 1.1 help, Qualcomm did not say loads in regards to the GPU. The corporate says it leads the business in efficiency per watt, and it put an emphasis on “sustained system efficiency” with its new GPU, so it ought to throttle much less. This needs to be an enchancment for gaming.

Qualcomm says the Hexagon 690 DSP has remodeled from a traditional DSP to a extra generic processor. The corporate pitches the part as an “AI platform” because of a brand new “Tensor Accelerator” for impartial community work.

The ISP—the chip that powers the digital camera—is quicker, too. It seems Qualcomm will be capable of do augmented actuality and different digital camera tips at 4K 60FPS. For video playback, there’s {hardware} accelerated h.265 and VP9 decoding, which ought to assist loads with apps like YouTube.

The Snapdragon 855’s Wi-Fi is getting upgraded, too. There’s help for “Wi-Fi 6” (aka 802.11ax) with 8×8 MIMO, which would be the subsequent large mainstream Wi-Fi improve over the present 802.11ac. I extremely suggest testing our in-depth Wi-Fi 6 primer from Jim Salter, however principally 802.11ax is extra about foundational enhancements that can make Wi-Fi work higher, moderately than dishing up enormous pace boosts. Wi-Fi is being dragged into the trendy period with novel options like the flexibility for a number of units to transmit on the identical time and bi-directional communication! Till 802.11ax, Wi-Fi has been one machine at a time, one route at a time, which is why Wi-Fi is usually so horrible.

The Snapdragon 855 can also be getting help for 60GHz 802.11ay, aka “the subsequent Wi-Gig.” 802.11ay would not have good penetration so it principally wants line-of-sight between units, however it may attain speeds as much as 10Gbps. Just like the now-defunct Wi-Gig, somebody must discover a use for this.

5G through an additional chip

Qualcomm’s largest energy within the SoC market is its modem expertise and mental property, because it’s one of many few gamers that may construct a CPU, GPU, and modem all in a single chip. A one-chip resolution presents a two-fold profit for a tool’s battery life: one chip makes use of much less energy than a two-chip SoC + modem resolution, and the only chip takes up much less house, which leaves extra room for a bigger battery.

The mobile business might be all about “5G” millimeter wave connectivity in 2019, and, certain sufficient, Qualcomm is looking the 855 “the world’s first industrial cellular platform supporting multi-gigabit 5G.” “Supporting 5G” is loads totally different from “built-in 5G,” although, and a Snapdragon 855 machine with 5G won’t get Qualcomm’s single-chip benefit this era. The 855 can have LTE on-board, as traditional, however these first-generation 5G units will want an additional chip, the Snapdragon X50 modem.

The additional chip means 5G goes to be larger, extra sophisticated, and extra power-hungry than 4G, so that you’re getting all of the downsides of first-generation community expertise. 5G makes use of a a lot greater frequency in comparison with 4G—30GHz and above—which suggests it has very poor penetration and might simply be blocked by buildings or your hand. To get across the “You are holding it incorrect” downside, Qualcomm suggests producers use a “beamforming” approach. This places massive RF modules in all 4 sides of the cellphone, permitting it to change to whichever module your hand is not blocking. Once more, this implies extra energy utilization and extra sophisticated units.

Somebody goes to should pay for all these additional 5G parts, and it appears like it’ll be shoppers. OnePlus CEO Pete Lau not too long ago instructed The Verge that 5G units would probably price $200 to $300 greater than 4G units. 5G networks aren’t actually up and operating but, and carriers will solely begin to launch 5G in choose cities in 2019. The excellent news is that 5G needs to be non-obligatory in 2019.

The Snapdragon 855 will come to units within the first half of 2019, with the Samsung Galaxy S10 a possible first touchdown spot.
