In 2025, Allwinner launched three new intelligent processors aimed at general tablet applications:A733, A537, and A333. These three “core” members are positioned as high-end, mid-range and entry-level processors, precisely covering the diverse needs of various levels of Android tablet products, applicable to: tablets, educational products, buddy machines, commercial display devices, e-books, cash registers, and other general tablet products, providing just the right performance support for different usage scenarios.
Hardcore Standard Configuration
▋ Powerful Core
All three processors integrate high-performance big-core CPUs.
▋ Worry-free Certification
All can pass Google GMS certification, meeting the practical usage needs of mainstream applications.
▋ Development Friendly
Allwinner provides a complete development kit, including SDKs, development and debugging tools, mass production tools, reference designs, and development documentation, significantly lowering the development threshold.
▋ Flexible Design
The hardware reference designs of the three chips have certain compatibility, allowing customers to differentiate performance levels and peripheral component stocking for the same series of terminal products; among them, A537 and A333 achieve complete Pin to Pin compatibility, making design switching smoother.

PPA Dynamic Balance, Avoiding Specification Redundancy
Allwinner A733, A537,A333 three processors adopt a similar series design language, fully demonstrating Allwinner’s deep technical accumulation and stable platform capabilities in the Android tablet processor field. More importantly, Allwinner, based on a profound insight into the general Android tablet market, does not simply stack performance when defining different level chip specifications, but precisely anchors the SoC’s “impossible triangle” PPA (Performance, Power, Area), achieving a clever balance between specifications and needs, performance and cost. This not only reflects Allwinner’s strong technical strength but also demonstrates Allwinner’s precise understanding of the general tablet market demands.
