Snapdragon 855 = 7nm + Kryo 485 CPUs

Snapdragon 835 and 845 are built on the same process node of 10nm, however, the Snapdragon 855 takes the latest process in lithography which is the 7nm enabling fabrication of more logic density (transistors). The high density of transistor on the same die size enable better performance.

Snapdragon 855 = Adreno 640 GPU

The SD855 upgrades the GPU from Adreno 630 in SD845 to Adreno 640. The Adreno 540 GPU in SD835 is still going strong as we can see in some premium smartphones from Sony, Xiaomi, etc.

Snapdragon 855 = 5G Cellular Modem + Better RAM + 3x AI

The modem became X24 and offers speeds up to Cat.20. Moreover, it becomes 5 G Ready and 5 G communication can be done separately by adding 5 G module separately. However, it is not standard 5G compliant. The 5G module also supports communication in the 6 GHz band, but seems to be rather weak against obstacles. The generation of HVX is in the fourth generation, the AI performance is 7 Trillion (3 times of 845, 2 times of the first 835), the DSP performance is doubled of 845.

Other features of SD855.

Camera ISP was updated to CV-ISPs. This CV stands for Computer Vision. Simply put, it means that you have the ability to perform operations related to image processing according to software instructions, such as creating 3D surface image (stereoscopic surface image, 3D-SI) from images and images in real time.
Up to now, speaking of ISP, ISP had already dealt with ordered instructions. To put it briefly, when we pressed the shutter, we finished processing the image in a fixed range. However, with this function, its control range can be applied to simultaneous synthesis, follow-up, analysis, etc. Well, the function that can be done since it is the first generation seems to be related to 3D-SI. And, in relation to Video, it corresponds to HDR 10 +.

In DSP-related, Hexagon seems to have strengthened the NPE-related process that has changed to 690, but since it is not written as NPU, Qualcomm does not seem to call it NPU. Although it is shown in the table that NPU function is built in once, actually it is clearly said that yes.

Audio part seems to have probably not changed. However, since DSP etc. are being enhanced, it is said that it is evolving to the extent that plural assistant system processes can be performed simultaneously. Although it is written as a function of Aqstic, probably it is probably not a function of the Aqstic main body just by requiring DSP interlocking.

Snapdragon 835 Vs 845 Vs 855 – Geekbench & AnTuTu

Snapdragon 835 Vs 845 Vs 855 – AnTuTu

Snapdragon 800 series will surely maintain the highest level in smartphone process next year. Apple’s A series is also the best if it adds compatibility with benchmarks and applications (iOS), but Apple can not make such a versatile product. After all, the baseband chip does not finish putting in from Intel or Qualcomm, and since the connection function with external equipment is abundant, the pure performance of GPU and the like seems to be raised considerably this time as well.
