OPPO Find X7 自研潮汐架构详解：刷新天玑 9300 性能上限

2024 has arrived, and for the smartphone industry, the new year will also usher in a wave of new machines. And the most talked-about at the moment is the OPPO Find X7 series, which will be officially released on January 8.

Although the launch event has not yet begun, a lot of information about the new Oppo Find X7 series has already been revealed, especially the standard version of the Oppo Find X7, which is more powerful than the industry's Pro models, despite being the standard version.

The OPPO Find X7's benchmark score / gaming performance is high, and it is inseparable from the self-developed Tidal architecture

For example, according to the previously exposed Antutu running score news, the Antutu running score of the OPPO Find X7 Standard Edition reached 2270677 points, including CPU521690 points and 911683 points for GPU. You know, this is indeed a difficult achievement for many Pro-level flagship phones at present.

Not only that, but on January 3, OPPO also released the frame rate data of the standard version of the OPPO Find X7 when running a well-known open-world mobile game.

The data comes from the game test of four media, among them, the ambient temperature of the Xiaobai evaluation is 25°C±0.5°C, the screen brightness is 350nit, the sound is 50%, the performance mode is on, and the 30-minute game time is measured at 60.8FPS.

WHYLAB's test ambient temperature is 25°C±1°C, screen brightness is 260nits±5nits, game image quality is extremely high, rendering resolution is 720P, running for 30 minutes, and the average measured frame rate is 59.98, which is also a very stable performance.

The other two groups also had similar test results, with the Phoenix Home evaluation measuring a maximum 30-minute average frame rate of 60.1 fps, while Geek Bay's test result was also 60.1 fps. All four media outlets tested the first score on the same platform.

The same platform here naturally refers to the MediaTek Dimensity 9300 flagship platform. According to the information we have so far, the standard version of the OPPO Find X7 is equipped with the Dimensity 9300 mobile platform.

When it comes to the Dimensity 9300, the biggest attraction of this flagship chip platform is that it adopts an innovative CPU all-large-core architecture design, including 4 Cortex-X4 ultra-large cores with a maximum frequency of 3.25GHz, and 4 Cortex-A720 large cores clocked at 2.0GHz, which has a peak performance improvement of 40% compared to the previous generation. At the same time, the GPU is the first to adopt the next-generation flagship 12-core GPU, the Immortalis-G720, which delivers a 46% increase in peak performance compared to the previous generation.

The key to this lies in how to match the efficiency of chip operation with performance through strong scheduling.

As a result, OPPO has developed a powerful set of software and hardware chip fusion technology solutions - Tidal Architecture. Earlier, we saw that the OPPO Find X7 surpassed the industry's Pro-level performance performance, thanks to the help of OPPO's Tidal architecture.

How does Tidal architecture refresh the upper limit of chip performance?

So, what is tidal architecture, and how does it refresh the upper limit of chip performance? Today, I might as well take a look at it with you.

Tidal architecture can be said to be a set of solutions formed by OPPO's self-developed chip-level software and hardware fusion technology. It is named because Tidal is one of the most powerful and inexhaustible sources of natural energy on Earth, a reference to the innovative technology that will bring unstoppable performance to the Find X7.

As we mentioned earlier, the key to tuning the Dimensity 9300 is to improve its operating efficiency. At present, there are two major bottlenecks in improving the computing efficiency of SoC chips:

First, the performance link of the smartphone follows the classic von Neumann structure, with the separation of storage and computing, and the storage read and write speed is much lower than the CPU computing speed.

Second, the scheduling scheme of the chip lacks scenario-level cognition.

Therefore, in order to improve efficiency, it is necessary to go deep into the chip architecture layer and optimize storage and computing for specialized scenarios. But in the past, from the chip's L1 cache to the system cache has always been the technology area of chip design companies, and this time, OPPO has broken through the boundaries of technology through the Tidal architecture and mastered the use of L3 cache to system cache.

Specifically, through in-depth joint research and development with chip manufacturers, OPPO has deeply integrated the Tidal architecture into the on-chip caching system that traditional mobile phone manufacturers cannot use in a refined manner, and has jointly designed cache partitions, CPU/GPU dynamic ratios, and fast track solutions for clean data with chip manufacturers.

Through the Tidal architecture, OPPO has implemented dynamic matching of system-level caches for the first time, dynamically allocating system-level cache resources to CPUs and GPUs based on computational tasks and rendering tasks in real time. With this unique technology, Tidal Architecture achieves an average energy efficiency gain of 8% in system-level cache scheduling.

At the same time, the Tidal architecture also supports a new scenario-level computing power and power consumption analysis model within the chip, which can realize dynamic computing power and power consumption evaluation and analysis based on a single scenario, as well as real-time dynamic disassembly of each computing task into the computing power distribution of each computing unit on the chip, find out the best combination of energy efficiency, and achieve more competitive energy efficiency performance for diverse user applications.

In other words, it can allow the computing unit to run more in the dessert range of the best energy efficiency, whether it is a daily application such as Kuaishou short video scene, AutoNavi map scene, or Weibo, browser, etc., can achieve significant energy efficiency improvement.

By precisely scheduling the GPU's computing power, Tidal Architecture also provides excellent control over display latency, enabling an unprecedentedly smooth and consistent experience for the Find X7. In a test that simulated users launching the app 320 times a day, the Tidal Architecture Find X7 had a standard deviation of only 11ms, which was the first among all flagships, and even surpassed the iPhone, which is known for its stability and smoothness, and for the first time, the Android flagship had a consistent startup performance experience that surpassed Apple's.

In general, the core advantage of OPPO's Tidal architecture is that, compared with traditional mobile phone brands that can only optimize performance at the ROM or RAM level, the Tidal architecture breaks through the boundaries of the performance optimization link and penetrates into the system-level cache and L3 cache that can only be optimized by chip companies, resulting in more powerful performance, higher energy efficiency, and better stability.

To achieve this, it is undoubtedly necessary to have chip-level technology research and development capabilities. As a company driven by technological innovation, OPPO has been committed to bringing better products and services to users through in-depth R&D investment and technological innovation.

According to the official data released by OPPO, as of September 30 last year, OPPO has applied for more than 95,000 patents worldwide, and the number of global authorizations has exceeded 51,000. Among them, the number of invention patent applications exceeded 86,000, and invention patent applications accounted for 90% of all patent applications. At the same time, in the 2022 ranking of the number of international patent treaty (PCT) applications released by WIPO, OPPO ranked 6th in the world, which shows that it does have quite strong technical reserves in multiple fields. And the launch of the tidal architecture,I believe it is also thanks to the technology and experience accumulated by OPPO in chip design and research and development in the past,I believe that what we see so far is just the tip of the iceberg,Tidal architecture on OPPO Find X7,There should be more amazing performance control performance。

In any case, the new OPPO Find X7 series will be released on January 8th, when we will have a deeper sense of the performance feast that this annual flagship will present, and we will also fully see how the Tidal architecture makes the chip performance surge, you can witness it with IT Home!
