What is the "very scary technology" of Huawei mobile phones?

Today, in the warm-up period prior to the release of smart phones, "a very scary technology" seems to have become a standard. There are hammers, millet, and Huawei.

Several conferences look down, and each "very scary technology" is different. The hammer's "scaring technology" is a TNT monitor that uses voice and touch to interact. For consumers who use TNT, we all have to whisper them and don't bother them. Xiaomi's "scaring technology" seems to be Xiaomi. 8 The transparent exploration version of the 3D structured light and pressure-sensitive screen fingerprint technology that was first introduced on Android phones, but in fact, the most frightening technology of Xiaomi 8 is still lower than the selling price of the same configuration product.

At the launch of Huawei’s glorious Play premiere at Huawei’s scary technology, Yu Chengdong personally debuted a technology called GPU Turbo, claiming that playing games is more stable and the daily operations are smoother. “High-end mobile phones can be more lasting and smooth, stable and full-frame operation. In large-scale games, mid-range mobile phones surpass competing products, and thousands of yuan machines can also play large-scale games.

However, GPU Turbo technology is still covered with a layer of mystery.

How much improvement can GPU Turbo bring to mobile phones?

Yu Chengdong said at the press conference that GPU Turbo can enable “graphic processing efficiency increase by 60% and SoC energy consumption by 30%”, but how much improvement can this figure apply to mobile phones? We can compare the actual machine.

In this comparison, the GPU Turbo technology is naturally released with the glory Play. The phone has a Unicorn 970 processor, 6GB RAM, 64GB ROM, and a 6.3 inch 2340x1080 resolution screen.

The reference model not equipped with GPU Turbo is the Glory V10 released last year. The phone's configuration at the time of launch is top notch: Unicorn's 970 processor, 6GB RAM+128GB ROM and 6” 2160x1080 resolution screen.

Glory Play’s resolution is 8.3% higher than the Glory V10. In theory, this has some negative impact on running points.

Glory V10's AnTuTu run was divided into 207986, and glory Play's AnTuTu run was divided into 200061. Glory V10 score was 3.96% higher than Glory Play, within the margin of error. However, it needs to be pointed out that in fact, Glory Play completed the test faster than V10.

In "Glory to the King," the glory of Play and V10's frame rate and stability, in fact, not too much —— can remain in the 60-frame or so for a long time, there will not be dropped frames in a complete game , and those who get Tencent special optimized mobile experience is almost the same. Strictly speaking, Glory Play feels even smoother for me, considering the higher resolution, so it is even more valuable.

By the way, even if it is the same version of "Lord of Honor", Glory Play is the default high frame rate mode is turned on, while the glory V10 is not, need to manually open.

Several other games, "QQ Speed," "Cross Fire," "Exciting Battlefield," "Army Attack," "Wildland Action," and "The King's Glory," are also similar to the "mdash;" Glory Play fluency is a bit better —— this is not repeated here.

How should GPU Turbo understand?

Turbo is intended to be a turbocharger used in automobiles. Later, Intel introduced the Turbo Boost concept to the PC industry to describe processor acceleration. So Turbo has overclocked meaning in the processor-related industry, and many times Turbo is also abbreviated as T. For example, Qualcomm's classic MSM8255T processor chip refers to the 1.4GHz version of the MSM8255 after the frequency increase, and the original MSM8255 1GHz frequency.

So simply to understand literally, GPU Turbo is a technology that relies on the GPU to improve the system's fluency.

To be clear, CPUs are better at controlling complex logic. GPUs are better at math operations because of the large number of ALUs and parallel architecture design (this is also the reason for AI and "getting mining" and using GPUs rather than CPUs).

In fact, as far back as Android 4.0, Google added GPU-enforced rendering to the system to improve the fluency of the phone. The principle is that GPUs that focus on graphics processing force image rendering and get faster than CPU rendering 2D images. Of course, the increase in compatibility and power consumption are the preconditions and later words of this effect.

From this point of view, the GPU to improve system fluency is not an emerging concept.

In addition, in addition to Google's system providers, terminal manufacturers have also worked hard to improve the fluency of mobile phones, especially low-end mobile phones.

In July 2016, Samsung launched Galaxy J2 Pro in India. This phone configuration is not surprising, only 2GB RAM + 16GB ROM, its biggest highlight is the first launch of Samsung's TST technology used to increase the speed of mobile phones & mdash;—TST, full name " Turbo Speed ​​Technology & rdquo; (Hey, this The name is very familiar, ah, mobile phone manufacturers name the product acceleration technology are relying on turbocharger?).

Samsung said at the time, after using this technology, small memory phones can be up to 40% faster than double-memory phones (well, this effect data is also a bit familiar?).

Then how does Huawei's GPU Turbo relate to the above-mentioned "GPU forced rendering" and "TST" technologies?

Let's take a look at Huawei's explanation of GPU Turbo.

Huawei’s reference to the media mentioned that “GPU Turbo's graphics processing acceleration technology for hardware and software collaboration breaks the boundaries of hardware and software, and reconstructs the traditional graphics processing framework at the bottom of the system, achieving hardware and software collaboration.” GPU Turbo can achieve similar HDR quality through GPU Turbo when the game does not support HDR (specifically, depending on the progress of Huawei and Glory communicating with third-party game manufacturers), and can customize various screen effects, such as Nostalgia mode, sharpening mode, cartoon mode, etc.

Huawei's in-house engineers disclosed to PingWest that so far, GPU Turbo is still a highly confidential technology, so even if it is the official explanation, it means something that is not said. But from this explanation and the GPU Turbo naming, PingWest speculates that the technology should be related to the processor's multithreading optimization and the system-side graphics processing interface call.

This is somewhat metaphysical, but for this, Samsung's TST is also half a catty. Their interpretation of TST is:

TST will reduce the size and background memory usage of native applications, including phones, text messages, etc., and place them on a dedicated home screen to optimize the memory management engine and intelligently free up memory.

However, the follow-up effects of these software optimization techniques still need further verification. Anyway, Samsung’s flagship fluency still needs to be improved.
