On December 27, OPPO announced the latest technological progress in the four major fields of AI, performance, communication, and privacy and security, including the first handset/hands-free dual-mode satellite call for smartphones, the first device-side application of 7 billion parameter large models, the debut of Tidal architecture and many other technologies, and these technology combinations will be implemented in the next-generation flagship Find X7 series.
Communication is the number one requirement for smartphones, and since the Huawei Mate 60 Pro was announced with satellite calling, satellite communication is becoming the standard feature in flagship phones.
"Unlike competitors who only support hands-free calls for satellite calls, OPPO can provide handset/hands-free dual-mode satellite calls for the OPPO Find X7 series through satellite antenna pattern control technology, which solves the slots of user privacy protection and unclear hands-free calls in extreme environments. OPPO hardware engineering terminal antenna expert Lu Bao said.
For typical scenarios with weak signals such as remote mountainous areas/rural areas, urban areas with complex signals, and indoor home office areas, OPPO has developed its own communication technology solution - Super Signal Engineering, which improves the full-scene communication experience of the Find X7 series from outdoor to urban areas and from urban to indoor through three major technical sections: antenna technology, smart communication, and near-field communication.
In terms of large models, following the launch of the self-trained Andean large model (AndesGPT) at the ODC (OPPO Developer Conference), OPPO announced that it will implement the industry's first 7 billion parameter model for device-side applications on the Find X7 series.
The Andean model is divided into multiple versions of 180 billion parameters, 70 billion parameters, and 7 billion parameters, supporting device-cloud collaborative deployment and diversified application scenarios. The Xiaobu assistant connected to the Andean model can help users write Moments, Xiaohongshu copywriting, draft PPT outlines, etc. By applying a large model of 7 billion parameters to the Find X7 series, many practical functions such as local call summary, hair-level subject extraction, AIGC removal, and background supplementation are realized.
Zhang Jun, general manager of OPPO Software Innovation Center, said, "To install the 7 billion large model into the mobile phone, the memory problem must be solved first. OPPO compresses the model from 28GB to 3.9GB through high-precision 4bit quantization and other model compression, inference engine acceleration, and hardware acceleration with in-depth cooperation with the chip platform, bringing a complete 7 billion parameter large model to the mobile phone side for the first time. ”
An industry source told the Deep Web that "models with 10 billion to 15 billion parameters can cover the vast majority of generative AI use cases." If the terminal can already support this parameter level, then all the calculations can be performed on the terminal, without the need for cloud processing, and the mobile phone will become a real personal assistant. ”
In response to the stringent demand of flagship end users for chip energy efficiency, OPPO announced its exclusive Tidal architecture technology for the first time to improve the efficiency of chip tuning.
In the case that the traditional Moore's Law miniature scheme is approaching the physical limit, it is very important to tune the chip and improve the computing efficiency of the SoC chip.
At present, there are two major bottlenecks in improving the computing efficiency of SoC chips: one is that the performance link of smart phones follows the classic von Neumann structure, with storage and computing separation, and the storage read and write speed is much lower than the CPU computing speed;
"Compared with traditional mobile phone companies that can only optimize the performance of ROM or RAM, the Tidal architecture determines the current application's demand for system resources based on a single scenario, and actively allocates more cache to the CPU if there are many computing tasks, and tilts resources to the GPU when there are many rendering task scenarios. Tidal architectures have been calculated to achieve an average energy efficiency savings of 8%. Hong Hansheng, director of software technology planning and architecture design at OPPO, revealed.
