The AX65 is the first of the high-performance out-of-order AX60 series from Andes Technology. Equipped with 13-stage pipeline, 4-wide decode, 8-wide out-of-order execution, AX65 targets the Linux application processor sockets of computing, networking, and high-end controllers.

The AX65 operates at speeds exceeding 2.0GHz on a 12nm process, boasting a SpecInt2006 score of 8.25 per GHz — outperforming the Cortex A75 with an efficient memory hierarchy. It also supports up to 8-core cache coherence with maximum 8MB shared cache. The AX65 is fully compliant with the RISC-V RVA22 profile, ensuring compatibility with Linux operating systems and software within the RISC-V ecosystem. On the security side, AX65 supports Enhanced PMP (ePMP) for further securing memory accesses, and K (scalar cryptography) extension for accelerating AES and SHA crypto operations. For Linux OS support, the AX65 supports VIPT L1 instruction cache, SV48 virtual address space, and 2-level TLB with simultaneous hardware page walkers. It also incorporates state-of-the-art branch prediction mechanism with TAGE-L algorithm, return address stack and 2-level branch target buffer. The AX65 can be used as an application processor in networking applications like Wi-Fi, 5GNR, and O-RAN, as well as in edge computing and industrial PCs. Furthermore, it is well-suited for serving as the primary controller processor in AI or other embedded applications.

Early customers in Asia, Europe and USA have been evaluating AX65 since August. Customers in multimedia and AI/ML have already signed up. The AX65 with Linux and RTOS support as well as development tools is available immediately for general licensing.
