We are proud to announce the launch of Milk-V Pioneer, an advanced micro ATX motherboard featuring the high-performance 64-core RISC-V CPU - SOPHON SG2042. Milk-V Pioneer aims to provide outstanding processing power and a versatile hardware platform for RISC-V developers, offering a perfect solution to meet a wide range of computing requirements, from daily tasks to demanding server applications.

Features & Specifications

Milk-V Pioneer is a groundbreaking RISC-V development platform with numerous outstanding features, including:

These features not only seamlessly integrate with existing infrastructure but also ensure a powerful and user-friendly development experience, making Milk-V Pioneer an ideal choice for both RISC-V ecosystem enthusiasts and professionals. The launch of the Milk-V Pioneer series of products has milestone significance for the RISC-V software ecosystem, completely solving the long-standing problems of relying on virtual machines and lengthy compilation times during the OS distribution build process, and taking the entire RISC-V software ecosystem to new heights.

Our crowdfunding campaign features the micro ATX Milk-V Pioneer motherboard, as well as a pre-built Milk-V Pioneer Box that comes with dual 10G network cards and a discrete graphics card, allowing users to set up and use the system right out of the box.

Power by SG2042

The SOPHON SG2042 server chip is based on the RISC-V instruction set architecture (ISA) and features a 64-core server-grade chip designed to meet high-performance computing needs. It offers scalability, flexibility, and customization, with integrated circuits including high-speed cache (L3Cache 64 MB), memory controllers (4 DDR4-3200), network interfaces, and PCI Express® controllers (x32 PCIe Gen 4.0), supporting general-purpose operating systems such as Linux. The SG2042 has a clock speed of 2 GHz and a design consisting of 16 clusters, each containing 4 RISC-V cores, with each core featuring L1-D 64 KB and L1-I 64 KB. Each cluster shares a design of L2 1 MB. The L3 System cache has a capacity of 64 MB. The SG2042 supports interconnect between two chips via CCIX and has 4 DDR4-3200 controllers, supporting RDIMM, ECC, and UDIMM. The chip also has 32x PCIe Gen 4.0 interfaces, integrated eMMC 5.1, SDIO 3.0, SPI x2, I2C x4, UART x4, and gigabit Ethernet MAC.

The compiler suite ZCC has announced full support for the SOPHON SG2042 RISC-V server chip. This toolset supports agile chip design, development, and validation, as well as comprehensive RISC-V software development, debugging, simulation, performance analysis, and software/hardware co-simulation and validation. In SPECint 2006 server benchmark testing, the ZCC compiler can improve the single-core performance of SG2042 by an average of more than 15%. In some commonly used automatic vectorization performance tests of AI operator libraries, the zcc automatic vectorization operator library shows an average improvement of 18% compared to handwritten RVV builtin operator libraries, and up to 100 times better performance than open-source GCC and LLVM RISC-V compilers. With ZCC’s OpenMP automatic parallelization support for SG2042, using the high-performance ZCC compiler can not only achieve the best single-core and multi-core performance but also significantly reduce the maintenance costs of RISC-V function libraries and AI operator libraries.

Fedora 38 has been compiled and supports Milk-V Pioneer Edition. It can run LXDE, XFCE and GNOME desktop environments with stable performance. It also has a rich set of applications, including Podman, LibreOffice, Firefox, media players, and even many classic 3D games on Linux, making it indistinguishable from a Linux PC. In addition, Fedora systems can also run ROS2 systems, laying the foundation for more future applications in artificial intelligence and robotics. Currently, Milk-V Pioneer uses Linuxboot to boot into Fedora. By the end of Q2 2023, it is planned to start using UEFI (EDK2), and by the end of Q3, ACPI is planned to replace device tree to boot the Linux system. During this time, the Fedora image will continue to be updated with the addition of software packages needed by the developer community.
