On December 14, the second self-developed chip of OPPO - Mariana Y - was released. It is undoubtedly an excellent Bluetooth audio core, adopts N6RF, 6nm RF technology, has an ultra-high speed transmission rate of 12Mbps, and can transmit 192kHz/24bit ultra-clear lossless audio. However, what puzzles many netizens is why OPPO chose to build a Bluetooth audio chip instead of other chips so carefully? In fact, behind this is OPPO's layout and ambitions. Their eyes are on the future, not just the current mobile phones.
First of all, OPPO undoubtedly attaches great importance to Mariana Y, and it is not just a simple gimmick. Mariana Y's 12Mbps ultra-high-speed transmission rate breaks through the limit of Bluetooth , and is the fastest Bluetooth frequency in the world at present. It leads Bluetooth audio transmission to enter the ultra-clear lossless era of 192kHz/24bit for the first time, and its strength is unquestionable. At the same time, it has the first dedicated NPU for the headphone end side, which can bring surging computing power of 590 billion calculations per second, allowing this chip to have the first sound separation technology on the headphone end side, supporting functions such as intelligent active noise reduction, high-definition spatial audio, and adaptive EQ calibration. In addition, the N6RF it uses improves the energy efficiency of the RF transistor on the one hand and reduces the size of the RF transistor on the other hand.
Mariana Y's strength and effort are undoubtedly huge, so why does OPPO attach so much importance to it? Because it may be the key to connecting the layout of the three core capabilities. In 2020, OPPO proposed the "3+N+X" technology transition strategy. "3" refers to the three underlying core technologies, namely Mariana Plan (self-developed chip), Pantanal Plan (cross-end system) and Andes Plan (intelligent cloud). Nowadays, these three core technologies have been presented one by one. Among them, Pantanal and Andes Smart Cloud need a powerful Bluetooth chip to connect in series, and this chip is Mariana Y.
This year's OPPO Future Technology Conference 2022, smart cloud and health concept products were unveiled one after another. OPPO's "three-in-one" strategy was recommended in an orderly manner, and Mariana Y's "sound separation" technology is the key to further improving product intelligence. Its "sound separation" technology can separate the sounds of human voices or other specific instruments from an audio file. The current algorithm can separate and generate up to four independent audio tracks - vocals, drums, bass and others. When the chip separates the voice from the complex sound, users can convey their instructions more clearly, and use them to control the smart cloud or health concept products at home to achieve a relatively ideal control experience.
OPPO ultimately hopes to achieve integrated core and cloud, multi-terminal integration, and give smart terminals a true smart experience, which cannot be done by one or two products or mobile phones alone. Unlike the Mariana X before, Mariana Y can be used independently on the device when delivered. Its high bandwidth, low power connection, and certain AP performance characteristics can be used on various wearable devices or home devices to comprehensively improve the smart experience of OPPO products, which is very important for OPPO's subsequent development in the smart home era.
We can completely imagine that when Mariana Y finally uses OPPO's headphones, watches and various IoT devices, the comprehensive smart experience will be significantly improved, and the connection capability and control experience will be significantly different from now. It is precisely because OPPO's attention has gone further that Mariana Y was finally built into a Bluetooth audio chip. I believe it will prove its position in the ecosystem in the future.
