The GPU Turbo conference has just ended. There are many comparisons and experiences on the first models equipped with GPU Turbo technology on Weibo. There is also speculation and speculation on the principles of GPU Turbo. Everyone wants to dig out the secret behind GPU Turbo.
In fact, when the conference put forward a performance improvement of 60% and a power consumption reduction of 30%, people with a little technical knowledge will be surprised at the amazing power of GPU Turbo. After all, it is highly developed and concentrated in the smartphone industry. Today, it's not easy for a vendor to get a 10% performance boost, not to mention 60%.
In the face of outside suspicion and incomprehension, Huawei also maintained a fairly open attitude.
Dr. Wang Chenglu, President of Software Engineering Department, Huawei Business Solutions, answers GPU Turbo key information
At the EMUI public class held on June 14th, 2018, Dr. Wang Chenglu, the president of Huawei's consumer business software engineering department, personally answered some of the key information of GPU Turbo technology, and unveiled the mystery of GPU Turbo for everyone.
—Why did Huawei do GPU Turbo?
Different from the traditional R&D process, doing GPU Turbo is not a top-down design requirement. On the contrary, it originates from the bottom-up pressure transmission of tens of millions of consumers. Different configurations of mobile phones have a smooth operation. The needs of the game, and when there is a chance to solve this problem from a non-pure hardware approach, GPU Turbo technology has emerged.
Dr. Wang further explained that Huawei's GPU for Kirin is taking a high-frequency and low-core path. Theoretically, high-frequency design can bring very good performance, but it also needs to further control power consumption. And GPU Turbo technology is adopted. The combination of software and hardware will make the use of 'muscle' more efficient in re-planning, which is to increase the frame rate performance at the same time, but also reduce the power consumption of fever.
Despite this, Dr. Wang said that GPU Turbo still takes more than 5 years from the start of the project to R&D. However, from the results, Huawei's proactive investment in GPU Turbo is worth 120%.
——How does GPU Turbo work?
Of course, Rome cannot be built in one day, and revolutionary technology will not come out from the ground without any reason. The success of GPU Turbo is based on the progressive and systematic transformation of Huawei EMUI to Android.
Since EMUI 4.0, Huawei has made Sensorhub LiteOS, unified the use of sensors, and greatly reduced the power consumption of mobile phones. By EMUI 5.0, Huawei has introduced a new file system, F2FS, with Ultra Memory technology to optimize memory scheduling and let EMUI do To the long-term use is not stuck.
In the continuous innovation and development of EMUI, Huawei has also exported some outstanding results to Google, such as F2FS file system, Vulkan graphics engine, etc.
After all this 'preparatory work' is done, with the EMUI 8.0 version upgrade, Huawei can better work out the GPU Turbo technology, and only in these innovative solid foundation, GPU Turbo can play its true strength.
He Gang, President of Huawei Mobile Phone Product Line for Consumer Business Introduces GPU Turbo at CESA
Specific to the majority of consumers are most concerned about, GPU Turbo how to significantly increase the number of game frames, Dr. Wang gave a very detailed answer.
For the game, the two adjacent frames are often the same in many places. Mobile gamers should be aware of this. Your frame is in the G-Gang container. The next frame has a very high probability. In the container. Especially for some LYBs, it is very likely that the whole game will be stuck in the grass. The game will remain in the same picture for 30 minutes.
So GPU Turbo technology will only render the scene where the picture changes when it predicts that there is no difference in the next frame of the game screen. For example, 80% of the pictures may be consistent between 2 frames. GPU Turbo Will allow the chip to render only 20% of the change, thereby reducing the GPU's 80% workload.
The reduction of the rendering workload has greatly increased the delay of the frame number of the next frame. It takes 16.7 milliseconds for the user to feel the frame drop. Huawei GPU Turbo can control the rendering time of the next frame within 7 milliseconds. In less than 3 milliseconds, the rendering of the next frame is completed.
Reasonably dispatch GPU resources, save GPU performance to the most needed places of the game, this is the secret that GPU Turbo let the game run full frame.
- In addition to games, GPU Turbo can do?
GPU Turbo is a revolutionary technology. For users, its function will not be limited to only a few popular games. This is especially true for Huawei who has spent five years of energy.
And more importantly, through the OTA upgrade, many Huawei models can enjoy this new technology.
Someone just announced that Huawei's mobile phones will gradually upgrade GPU Turbo technology
Huawei's Mate 10 series will be the first Huawei mobile phone to support GPU Turbo. Mate 10 will open the membership service application channel at the end of June and launch version pushes one after another.
Huawei's other series of mobile phones will also gradually upgrade GPU Turbo technology in this year. In July, Mate RS, P20 and nova 2s series, nova 3e, Enjoy 8 Plus, and Macbook 6 and Changshou 7s will be upgraded in August. The early flagship Mate 9, P10 series will be upgraded in October.
Finally, when asked whether 'friendship business will learn this technology within a few months', Dr. Wang laughed happily: 'I am very confident with the technology of GPU Turbo. Its technical threshold is very high. Other homes are unlikely to follow in a short time.'
It can be seen that GPU Turbo technology, which has spent 5 years of R&D investment, is indeed a rare software innovation at home and abroad, which greatly improves the gaming experience of Huawei users. This is also the result of Huawei's introduction of the Huawei P20 Pro Leica III camera. Once out of the industry's technical strength.
Yes, Huawei uses its unquestionable innovative strength to build an unsurpassable technical threshold between itself and others. After GPU Turbo, it is hard to imagine how the future of Huawei can bring surprises to consumers.
