Qualcomm Snapdragon 855 Performance
At the beginning of December last year, Qualcomm officially released its new generation flagship mobile platform Snapdragon 855 at the Hawaii Technology Summit.
According to Qualcomm, the Snapdragon 855 is based on the 7nm process and is the world’s first commercial mobile platform that fully supports multi-gigabit 5G connectivity, industry-leading artificial intelligence and immersive extended reality (XR). A new era of mobile terminals for ten years.
In terms of architecture, Qualcomm confirmed that the CPU part of the Snapdragon 855 is based on the deep development of the Cortex-A76 architecture. The official name is Kryo 485, which provides a super core, three performance cores and four efficiency cores. It is 2.84 GHz, 2.42 GHz, and 1.8 GHz.
Among them, the super kernel is the first design introduced on the Snapdragon 855, and its main frequency is higher than other cores in the Snapdragon 855 CPU. The higher performance CPU also achieves a better balance between optimal performance and energy efficiency. The most intuitive benefit of this core for the Opteron 855 device is that the application open speed is significantly higher than other 7nm platforms.
On the GPU side, the Opteron 855 integrates the latest Adreno 640 with support for Vulkan 1.1 API, 10bit HDR, 4K HDR display (support for external), H.265 specification and VP9 decoding.
In terms of performance, compared to the Snapdragon 845, the Snapdragon 855’s CPU performance is up to 45%, and GPU performance is up to 20%.
On the DSP side, the Snapdragon 855 was upgraded to the Hexagon 690, including a four-thread scalar core, four vector extension cores, and a tensor accelerator.
Among them, the new Hexagon tensor accelerator is independently developed by Qualcomm, specifically for AI, designed to accelerate multidimensional mathematics and integrated nonlinear functions.
The relevant specifications of the remaining Snapdragon 855 have been interpreted before, and interested readers can refer to the related articles published by Ann Bunny.
In theory, the performance improvement of the Snapdragon 855 is really satisfying, so what is its actual performance? At the recent CES show, Qualcomm specifically demonstrated the performance of the Snapdragon 855. Let’s take a look.
This test uses the development prototype of Qualcomm Snapdragon 855 mobile platform, the detailed configuration has not been announced, but from the data displayed by Ann Bunny, the built-in is 6GB memory and 128GB body storage space, screen resolution The rate is 2888×1440.
In terms of running points, the actual performance of this Snapdragon 855 development prototype in the Bunny v7 version is 362110, including CPU score of 121795, GPU score of 155578, UX score of 73994, and MEM score of 10743.
What is the concept of 360,000 results? From the current Android phone performance rankings of Ann Bunny, it has significantly exceeded the Kirin 980 and Snapdragon 845 related devices, which is the strongest in the Android field.
After analyzing the background samples, Ann Bunny found that the performance of the Xiaolong 855 development prototype can even exceed 370,000. The highest score of the current rabbit is 374666, including CPU total score 127167, GPU total score 157333, UX total Divided into 77,212, the total memory is 12,954.
In order to let everyone know more about the performance of the Snapdragon 855, Ann Bunny chose a 6T (representing the mainstream Snapdragon 845 mobile phone), Huawei Mate 20 (representing the Kirin 980) and the prototype of the Snapdragon 845 developed in the same period last year. The results are compared. Among them, the scores of one plus 6T and Mate 20 were taken from the average score of the Anbi rabbit performance list in December 2018, while the performance of the Snapdragon 845 development prototype was measured by the author in the same period last year.
Through detailed performance comparison, we can see that the Snapdragon 855 has obvious advantages over the Snapdragon 845 and the Kirin 980 in terms of CPU, GPU and UX, but it lost in the MEM (memory + storage) test. Kirin 980’s Mate 20.
It should be noted that the speed of the memory and memory chip has a great influence on the MEM score. This Snapdragon 855 device is just a prototype. The specifications of the memory chip are not necessarily the strongest. In the future, manufacturers will adopt faster memory and After storing the chip, it should be able to make up for this gap.
In terms of total scores, the Snapdragon 855 is more than 17% ahead of the Kirin 980, and has increased by more than 22% compared to the mainstream Snapdragon 845, compared to 36% compared to the LT 845 development prototype in the same period last year. .
In terms of CPU scores, the Snapdragon 855 is nearly 7% ahead of the Kirin 980, and has increased by more than 31% compared to the mainstream Snapdragon 845. This is an increase of more than 32% compared to the LT 845 development prototype in the same period last year. .
In terms of GPU scores, the Snapdragon 855 is more than 38% ahead of the Kirin 980, and has increased by more than 21% compared to the mainstream Snapdragon 845, compared to 44% compared to the BM 845 development prototype in the same period last year. .
Having said that, it can explain why we have to join the early Snapdragon 845 development prototype as a comparison. In general, Qualcomm will update its SoC GPU drivers from time to time to bring more performance. After several driver upgrades, the GPU score increased from less than 110,000 points to nearly 130,000 points, and the total score increased from 260,000 to more than 290,000. GPU performance also affects some UX scores, but Does not affect CPU and MEM performance).
Therefore, the measured results of the Qualcomm Snapdragon 855 development prototype are for reference only. In the future, Snapdragon 855 should be able to release the performance potential to a greater extent in the products of major manufacturers, and Qualcomm should also continuously update the GPU driver and optimize it. performance.
Then the question is coming. When will we be able to buy the Snapdragon 855 mobile phone? At present, Samsung has announced the release of the Galaxy S10 family on February 20. This should be the first flagship of the Snapdragon 855 that can be listed on a large scale. It is expected that we will be able to buy it in China in March, when the domestic manufacturer’s Snapdragon 855 mobile phone will be available. It should also be released and listed.
