On December 27, OPPO held a technical communication meeting for OPPO Find X7 series products. OPPO said that as of September 2023, the number of international PCT patent applications has ranked among the top 10 in the world for four consecutive years, and ranked among the top three Chinese companies for four consecutive years.
OPPO's ANDesGPT model has three technical features: personality exclusivity, dialogue enhancement, and device-cloud collaboration. AndesGPT adheres to the collaborative deployment of devices and clouds, covering a variety of different parameter scales from one billion to more than 100 billion, and can achieve intelligent scheduling according to user needs in different scenarios through division of labor, complementarity, and collaboration. Through strong knowledge, memory and tool capabilities, the ANDESGPT large model brings a broad range of knowledge to Xiaobu Assistant, as well as personalized and exclusive intelligent service capabilities. Through the original SwappedAttention technology, AndesGPT also solves the problem of first-word reasoning delay caused by long-term memory.
With the support of the 7 billion parameter large language of the ANDESGPT large model, the OPPO device has an ultra-fast first word response speed, and in the scenario of text content summary, the first word generation of 200 words only needs 02s, 2000 thousand words only need 29s, the maximum number of abstract words can reach 14,000 words, and it is easy to enter a common journal**.
The AndesGPT generative visual model also has the ability to generate high-quality and quickly, and has the ability to cut out the picture at the hair-level level, and the background is naturally generated after the cutout, while the large model relies on the Andean intelligent cloud, which supports flexible deployment of computing power, rapid iteration of the model, and AI security firewall, which is the specific content of the OPPO Find X7 series in AI.
In terms of software, SoCs are currently facing two major problems: storage and computing separation and chip scheduling. To this end, OPPO has brought a new tidal architecture and a self-developed chip software and hardware integration technology stack. In response to the problem of storage and computing separation, OPPO said that in the classic computer architecture, increasing the cache is the most unsatisfactory means to improve efficiency, and multi-level cache improves computing efficiency. However, traditional manufacturers cannot refine the use of on-chip cache, but after 2 years of research, OPPO has mastered the use of three slowdowns to the system cache, and designed a partition management mechanism, which can dynamically allocate cache resources according to different types of tasks, so as to achieve an average energy efficiency saving of 8% and a general energy efficiency improvement of 4% on the basis of lossless performance. As for chip scheduling, OPPO has in-depth cooperation with chip manufacturers to finely disassemble the scene requirements, schedule and allocate the optimal solution, and run in the optimal energy efficiency range.
In terms of fluency, Android faces three problems: touch response consistency, thread scheduling consistency, and display delay consistency, especially the last problem. This requires a dynamic display synchronization clock, dynamic GPU driver enhancement, to surpass Apple's boot performance consistency experience, and deeply involved in the design of the next generation of flagship chips, more surprises can be looked forward to the Find X7 series press conference.
In terms of security, OPPO has obtained many authoritative security and privacy certifications in the industry, and OPPO adheres to the principle of full-link application security governance, preventing location security risks, and controlling full-link data security. Previously, the VIP mode supported by the independent security chip equipped on the Find N3 was widely acclaimed, and the Find X7 series will also be equipped with the same national secret secondary independent security chip as the N3, and the Find X7 series comprehensively protects the security and privacy of users from software to hardware.
Next is the sharing of communication technology,Find X7 series will be OPPO's first product to support satellite communication,For the first time, it supports handset hands-free dual-mode satellite calling,It can avoid losing connection when the phone is placed near the head。 This is thanks to the OPPO satellite antenna pattern control technology, which can make the antenna have two completely different directions, and can dynamically adjust and align the satellite according to the user's attitude.
In terms of cellular networks, OPPO has launched the Super Signal Engineering Program, and has made progress in antenna technology, smart communication, and near-field communication technology. The first is the super low-frequency antenna, N28 N8 band high-performance four-channel receive link, low ECC high isolation technology;This is followed by handheld signal enhancement, with an average signal enhancement of 3db;There is also device-cloud system communication, which supports conference cloud acceleration, and the average one-way latency of meetings in weak network environments is as low as 52msAI network**, in scenarios such as subway and home communication network switching, the probability of switching to a better network in time is realizedCommunication sharing, tablet can achieve network connection through mobile phone;There is also a through-the-wall mode, a moving high-throughput mode that uses 160MHz bandwidth transmission, dual antennas to drop packets, and Wi-Fi Bluetooth full acceleration 30 etc.
All of these technologies will be available in the Oppo Find X7 series.
