As we all know, with the increasingly fierce market competition in the smartphone industry today, the competition between mobile phone manufacturers is no longer limited to simple "stacking" or "cost performance" disputes. Especially for head brands, competing for the first launch of the most advanced technology, or even the self-developed function of the power chip level, is their more commonly used and effective strategy today.
Taking the familiar vivo as an example, as early as 2017, they launched an independent DSP image optimization chip for night scene photo processing. And on the X9S and X9S Plus released that year, with the addition of independent DSP, Vivo has also become one of the earliest mobile phone manufacturers to realize the underlying processing of RAW format photos.
In 2019 and 2020, Vivo has customized and launched two 5G SoCs, Exynos980 and Exynos1080. This also makes them a rare domestic mobile phone manufacturer, can control the three major brands (Qualcomm, MediaTek, Samsung) SoC solutions at the same time, and can be applied to the flagship product line brand.
In 2021, Vivo launched their first self-developed image chip V1. This chip brings amazing night scene and video shooting capabilities to vivo's X70 series flagship model, and also makes the hardware competitiveness of vivo mobile phones enter the era of "self-developed chips".
When the time came to April 20, 2022, Vivo released a number of "core" technologies in one go, showing their latest achievements in smartphone performance tuning, self-developed chips, games and image experiences in a high profile.
Once again in-depth joint investigation, vivo to do "Tianji 9000 performance king"
Speaking of Tianji 9000, friends who pay attention to this year's mobile phone market will naturally not be strangers. As the long-lost true flagship master controller of MediaTek, Tianji 9000 has also become a top "god U" sought after by mobile phone manufacturers and consumers this year with its top performance that does not lose to competitors, excellent energy efficiency performance, and excellent game fluency.
However, what everyone may not expect is that the performance performance of the Tianji 9000 on the released models that you have seen before is probably not "complete". Because in today's event, vivo first showed the latest joint commissioning results with MediaTek for the Tianji 9000 chip.
For this joint investigation, Vivo and MediaTek began to prepare as early as a year ago or so, and the two sides jointly invested and set up an "elite development team" of more than 300 people. During the 350-day collaborative development of software and hardware, the team has discovered and optimized a series of user experiences of the Tianji 9000.
Including but not limited to:
By discovering and solving the rare performance probability fluctuation problem of Tianji 9000, the chip energy efficiency ratio is further improved, and the game endurance under high load scenarios is increased by 10%.
The "User Usage Scene Fluency Model" was established, the priority of the mobile phone system animation was redesigned, and the animation fluency when the mobile phone was under heavy load was increased by 50%.
The newly designed high concurrency computing mode solves the problem of CPU resource preemption, so that the joint tuning version of the Tianji 9000 is further greatly improved in application startup speed compared with the ordinary version.
Developed the "virtual cache unit" technology, and achieved an anti-aging fluency effect of 36 months on the Tianji 9000.
Of course, the most important thing is that through the in-depth joint investigation of vivo and MediaTek, the flagship SoC of Tianji 9000 has achieved a 1072221 score of Antutu on the latest model of Vivo. This not only far exceeds the running score of other models on the same platform before, but also exceeds the performance of some professional game phones, truly allowing the Tianji 9000 to achieve performance in the top flagship ranks.
Self-developed chip replacement, V1+ brings multiple evolutions of games, displays, and images
In addition to greatly improving the performance of Tianji 9000, vivo also brought another breakthrough in their self-developed chip technology today, a new V1+ self-developed chip, and the "second-generation dual-core standard" adapted to it.
First, let's take a look at V1+. As vivo's new generation of self-developed chips, V1+ continues the design concept of the previous generation of V1 "dedicated core", curing the functions in the form of as an as-applied integrated circuit, supplemented by an equivalent 32MB SRAM cache, which increases energy efficiency by about 300% and reduces power consumption by about 72%.
At the specific functional level, the biggest change of V1+ is that on the basis of V1's 3D real-time stereoscopic night scene noise reduction and MEMC interpolation, an AI super-resolution algorithm has been added. More importantly, through the in-depth joint investigation with MediaTek, Vivo has also successfully made the three functional features of V1+ all connected with the Tianji 9000.
For example, in terms of game technology, the vivo industry has launched the "GPU Fusion" that digs deep into the Tianji 9000 processing architecture and combines the capabilities of V1+ chips. It can coordinate the use of the CPU, GPU and APU of tianji 9000, through the AI computing power of the game for screen super-resolution processing, while calling V1+ hardware MEMC interpolation function to stabilize the game frame rate.
In this way, whether it is compared to the scene using GPU "hard calculation" or compared to other models that only interpolate frame processing, Vivo's "GPU Fusion" can theoretically bring further stabilization of the game frame rate and a greater reduction in game power consumption.
For example, in computational photography, vivo through long-term in-depth cooperation with MediaTek, the industry's first self-developed chip (V1+) and Tianji 9000 in real-time photography, video scenes under the processing power through. With the help of V1+ built-in "polar night noise reduction" algorithm, the new vivo mobile phone based on the Tianji 9000 platform will be able to realize the processing power of the V1+ chip in front, rear, full time and full focus, and even shoot a bright and clear picture in an environment of only 1 lux, which can be called the "night vision" in Android mobile phones.
To strengthen self-research, vivo is using the "core" to take its own flagship road
At this conference, in addition to the official announcement of the results of the in-depth joint investigation of Tianji 9000 and the show of the new self-developed chip V1+, vivo actually has many interesting details.
For example, in the joint investigation process between vivo and MediaTek for nearly a year, more than 30 new technology patents have been jointly generated by both parties.
For example, although the current flagship SoC is generally equipped with a ready-made AI photo metering algorithm, vivo still feels that it is not accurate enough, so it wrote a set of "AI perception engine" in the process of joint tuning, which increased the camera's metering brightness accuracy by 16% and the white balance accuracy by 12%.
In addition, vivvo also "broke" the problem that today's mobile phone HDR camera function is developed, but the screen often cannot correctly display wide-gamut HDR photos. And developed XDR Photo technology, to achieve high dynamic high brightness photos on the mobile phone screen accurate color and brightness mapping. With the blessing of new technology, the local brightness of the photo display has increased by 350% in one breath, which really allows users to intuitively feel the charm of the flagship imaging technology on the mobile phone screen.
In addition, in view of the image needs of professionals, vivo has also re-examined the "ZEISS natural color" function previously launched, re-refined the functions that have been launched, and further reduced the color difference after opening the "ZEISS natural color", so that its own image flagship model can provide more restored and closer to the real color of the naked eye in the future.
Not satisfied with the existing mature solutions in the industry, boldly breaking the experience pain points of similar products (including themselves), and actively developing innovative technologies at the chip level - from these practices of vivo, it is not difficult for us to see the characteristics of a head brand that is more confident and more wants to achieve some real experience breakthroughs.
