The top mobile chipset Snapdragon 855 received not only 5G-modem and improvements in the field of AI computing. One of the key features of the new product was a significantly increased performance of the graphics component of the platform. Representatives of Qualcomm spoke in detail about the innovations that expanded the gaming capabilities of Android devices based on the new processor.
Graphics accelerator Adreno 640 was 20% faster than its counterpart in the composition of the Snapdragon platform 845. Updating the hardware component of the chipset significantly accelerated the loading of games on mobile devices. In addition, the Snapdragon 855 architecture allows virtual and augmented reality games to function with 6 degrees of freedom to enhance the gaming experience of users.
Increased performance in these applications is made possible by distributing the workload between the GPU, the Hexagon auxiliary processor, and the image processing unit (ISP).
One of the main chips of the chipset was Snapdragon Elite Gaming technology. Qualcomm's hardware and software package includes support for the Vulkan 1.1 graphics library, which provides applications with the ability to directly control GPU operations without "crutches" in the form of third-party drivers.
As a result, the loss of frames in mobile games can be reduced by 90%, making the picture much smoother. Especially noticeable performance improvement will be in multiplayer games.
Another advantage of the Vulcan API is high energy efficiency. Compared to the software interface OpenGL achieved 20 percent savings in battery consumption of flagship smartphones based on the new Snapdragon.
Thanks to the function of physically correct rendering (PBR), the interaction of light with surfaces in gaming applications looks as natural as possible. This technology is already used in PC-releases — with its introduction to the mobile market should expect a significant expansion of the list of ported to Android game hits.
The computing power of the platform is enough to run games with HDR support and cinematic image post-processing. Representatives of the company compared modern smartphones with the traditional monitors-the picture quality of actual mobile displays is not inferior to many desktop solutions. If necessary, the image from the mobile device can be displayed on the external screen even in 4K resolution.
An important component of online releases is connection stability. Snapdragon Elite Gaming technology includes a built-in quality of service (QoS) system that prioritizes game packages, preventing third-party applications from "pulling" traffic to themselves.
The sound component is also of paramount importance in games, especially in multiplayer shooters. The latest version of the Qualcomm AptX codec guarantees high sound quality with a minimal delay even when using Bluetooth headphones. For the quality of the signal is a proprietary Qualcomm DAC Aquatic with features surround sound and noise reduction.
The energy efficiency of the new platform has also improved significantly. Despite the increase in graphics power, the device based on Snapdragon 855 is able to work longer on a single battery charge than its predecessor.
The emergence of new gaming smartphones with support for Snapdragon Elite Gaming technology is expected in 2019 with the beginning of commercial deliveries of Snapdragon 855.
