OPPO has revealed that its line of in-house chipsets has a new member as part of its ongoing Inno Day 2022 event. The MariSilicon Y is also its maker's first ever custom SoC for sound, designed with "industry-first" technology to achieve "ultra-high" transmission rates over Bluetooth. It is also rated to support lossless audio and integrates its own neural processing unit (NPU) for hundreds of billions of calculations per second.

Like its predecessor, the MariSilicon Y has its own "high-performance" NPU; however, unlike the X, the in-house chipset is geared to process audio rather than images or video. OPPO claims that part of the point of developing it is to put all that "processing power" to the task of conferring personalized spatial audio on the devices equipped with it.

OPPO is also confident that a MariSilicon Y-branded product will go beyond the typical limits of Bluetooth to reproduce the experience of wired audio over the standard. Such claims have been made before, although the OEM asserts that the new chipset will be doing so in 24-bit audio at up to 192kHz "for the first time".

Furthermore, the resulting "ultra-high-speed Bluetooth solution" is rated for an "unprecedented" bandwidth of 12 megabits per second (Mb/s) - then again, this apparently requires OPPO's new custom URLC codec, meaning that MariSilicon Y-enabled devices might have a walled garden of compatibility going on.

Nevertheless, the OEM implies that this might be worth it for access to the "industry-first" use of N6RF to mobile audio platforms. It is a CMOS process for radiofrequency (RF) applications also associated with the requirements of 5G and Wi-Fi 6/6E that, as OPPO claims, refines the space it takes up on a chip by 33% for power savings of up to 66%.

OPPO has yet to hint at the identity of the first-ever MariSilicon Y-powered personal device, although there may be some solid candidates on the way. They may include the reportedly upcoming Find X6 flagship smartphones - presuming the imminent Find N2 or N2 Flip do not have the honor.
