Chinese RISC-V developers Milk-V Technology and SOPHGO recently announced their collaborative open source Milk-V Pioneer developer motherboard and workstation based on the SOPHON SG2042 RISC-V server SoC. The SOPHON SG2042 is a 64-core, 2 GHz SoC based on T-Head Semiconductor's XuanTie C920 64-bit processor design which features clusters of one to four cores, each a 12-stage out-of-order multiple issue superscalar pipeline, and a 128-bit vector engine based on the preliminary RISC-V V Extension version 0.7.1. The SG2042 packs in 64+64 KB (I+D) L1 cache per core, 1 MB of L2 cache per core cluster, 64 MB of L3 system cache, a quad-channel DDR4 controller, and 32 lanes of PCI-E Gen 4. The SG2042 contains no integrated graphics solution.
The Milk-V Pioneer incorporates this highly threaded RISC-V SoC with a modular and expandable standard mATX motherboard featuring four DIMM slots with support for up to 128 GB of DDR4, three full-length PCI-E slots wired for Gen 4 x8, two M.2 M-Key PCI-E Gen 3 x4, one M.2 E-Key for PCI-E 3.0 x1 and USB 2.0, eight USB 3.2 10 Gbps ports, five SATA 6 Gbps ports, and a pair of 2.5G Ethernet ports. The bulk of this I/O runs off an ASMedia ASM 2824 PCI-E switch, however the PCI-E Gen 4 ports run directly off the SG2024 SoC. Milk-V Pioneer is also being offered as a prebuilt small form factor workstation which puts the board into a small portable chassis called the Pioneer Box. The Pioneer Box includes 64 GB of DDR4-3200, 1 TB M.2 SSD, an Intel X520-T2 10G network card, an AMD Radeon R5 230 graphics card for display, and a 350 W power supply.
Milk-V has yet to launch the Pioneer, with a crowd funding campaign to begin soon. On the campaign page they commit to publishing hardware schematics and 2D motherboard design files ahead of the campaign launch on their GitHub repository. Standard warnings apply when it comes to these kinds of crowd funding sites and campaigns, as not all you see is what you get and success stories are few and far between.
