Last week, Qualcomm hosted a media event at its headquarters in San Diego and demonstrated for the first time on the site the performance of the Snapdragon 845 mobile platform. How powerful is the latest flagship chip in the Android camp? Let's take a look outside Media Android Police finishing the report.
The first thing to note is that running minutes does not represent the performance of the device in the real environment, the cell phone snapdragon 845 in the end how to play, after all, let the user experience .But undeniably, run points still have reference, after all This is a topic that many manufacturers and users are concerned about.
Qualcomm announced the Snapdragon 845 mobile platform late last year, its CPU speed increased by 25%, GPU performance increased by 30%, taking into account the process or 10nm, this increase can be described as very impressive.
Like the Snapdragon 835 introduced last year, Qualcomm said in the media event that everything about the Snapdragon 845 is new, including the new CPU core (A75 and A55) and the new GPU Adreno 630. In addition to the regular CPU and GPU upgrades In addition, the Snapdragon 845 is also equipped with a Hexagon DSP, 2-3 times the performance of handling AI tasks, which is very important for machine learning technology.
It is also worth mentioning that the Snapdragon 845 also integrates a new ISP, greatly enhance the camera experience.In addition Snapdragon 845 also joined the HDR video encoding support, which means that the world's first mobile phone to support HDR video capture this year Came out the last thing to mention is the X20 LTE baseband, which allows the phone to dual SIM dual LTE mode standby.
However, the following sub-test run mainly with the CPU and GPU-related, other features have little effect on the results. As for the Snapdragon 845 and Snapdragon 835 specifications we can refer to the following figure.
Snapdragon 845 reference phone running sub-test
For the test is a Snapdragon 845 reference model, its shape and general models similar to the body covered with a lot of engineering code labels, as well as security watermark. There are some other parts not yet completed, but as part of A construction machine, too much discussion of its appearance is obviously not significant.Compared with the last year's Snapdragon 835 construction machine, the Snapdragon 845 engineering machine to much thinner.
In addition to carrying Snapdragon 845, this project has 6GB LPDDR4X memory, running Android 8.0 Oreo system.As for the test software do not have too much introduction, are common to run some sub-tools, such as GFXBench, GeekBench, 3DMark and Ann Bunny and so on.
In order to give you a better understanding of the performance of the Snapdragon 845, the models that we tested together include several handsets powered by the Snapdragon 835, including the Huawei Mate 10 Pro, Samsung Note 8, Galaxy S8 +, Google Pixel 2 XL, Plus 5 T. All machines were restarted prior to testing to keep the equipment running optimally.
Running sub-results overview
Can see that in all of the sub-test platform, the Snapdragon 845 reference handset performance are more than the other several Snapdragon 835 flagship single core run points to enhance the 500 + points, multi-core run points increased by 1400 points or so. Ann Bunny ran points to improve the way there are 60,000 points.
GeekBench
GeekBench 4 is well known as a running sub-platform, which is mainly used to test the CPU performance of the device.From the histogram below can be seen, the Snapdragon 845 single-core performance improvement is not too obvious, but the multi-core performance over the previous generation Big cut.
GFXBench GL Benchmark
GFXBench includes GL ES 3.1, 3.0, and 2.0 graphics performance tests, an important reference measure of game performance.
Ann Bunny
Ann Bunny ran sub-platform without too much introduction, it comprehensive consideration of the performance of key components of the device performance, including CPU, GPU, memory, etc., is the most popular running sub-platform. Dragon 845 run points to promote very obvious.
3DMark
3DMark is the most popular test-and-run tool for desktop platforms, using the mobile version of OpenGL ES3.0 / 3.1 Slingshot Unlimited, all with the same resolution for rendering images.
Webpage rendering performance test: Octane, Kraken, SunSpider, JetStream
Browser heavy users are sure to know that these are running sub-platform, Octane and SunSpider test JavaScript performance, the higher the score the better. Kraken and SunSpider scores as low as possible.
Compared with the Snapdragon 626/821/835
Snapdragon 845 and midrange chips Xiaolong 626 and the previous generation flagship chip Xiaolong 821 compared to a bigger upgrade.
to sum up:
Not surprisingly, Qualcomm released the flagship platform Snapdragon 845 once again topped the performance list, especially its image processing performance improvement is very clear, CPU performance than the Snapdragon 835 has also been greatly improved.Although the running points do not represent the phone Real performance environment, but it is undeniable, it provides an intuitive reference for us to evaluate a brand new hardware platform.In addition, it is worth mentioning that the performance mentioned here has not considered energy efficiency issues, the power saving Dragon 845 has better performance than before.
At the end of this month, Samsung Galaxy S9 is expected to be the first episode of Snapdragon 845. In addition, there is recent news that Sony will release the Snapdragon 845 flagship at the MWC 2018 at the end of the month. In the next few months, there will be more and more More Snapdragon 845 flagship handset will be unveiled one by one, such as Huawei's P20, HTC U12, etc. By the time Snapdragon 835 models should also cut prices, this year plans to change the phone's oil and so on.
