Sophgo SG2380 is an upcoming 2.5 GHz 16-core RISC-V processor based on SiFive Performance P670 cores and also equipped with a 20 TOPS AI accelerator using SiFive Intelligence X280 and Sophgo TPU that will find its way into a $120 desktop-class mini-ITX motherboard in H2 2024.
The RISC-V processor also supports up to 64GB RAM, as well as UFS 3.2 and SATA 3.0 storage, comes with an Imagination GPU for 3D graphics and a VPU capable of 4Kp60 H.265, H.264, AV1, and VP9 video decoding, plenty of interfaces, and the system can manage locally deployed larger-scale LLMs like LLaMA-65B without the need for external NVIDIA or AMD accelerator cards.

Oasis mini-ITX motherboard
While the SG2380 SoC will be used for various applications, I expect a range of computers, mini PCs, and laptops considering the geopolitical situation between the US and China, the first platform based on the 16-core RISC-V processor will be the Oasis motherboard.
Oasis specifications:
- SoC – Sophgo SG2380 16-core RISC-V SoC as described above
- System Memory – Up to 64GB 128-bit LPDDR5 5500MT/s
- Storage

- microSD card for OS booting and data
- M.2 M-Key socket for NVMe SSD (PCIe 3.0 x4)
- 4x SATA ports for HDD and/or SSD
- Video Output
- 2x HDMI ports up to 4Kp60
- 1x eDP with touch panel
- 2x MIPI DSI connectors
- Camera I/F – 2x MIPI CSI connectors
- Networking
- 2x 2.5GbE RJ45 ports
- 1x M.2 B-Key for 4G / 5G cellular module
- USB – 2x USB 3.0 ports, 2x USB 2.0 ports, 2x front panel USB 2.0 interfaces, 1x USB-C port with DP alt mode
- Expansion
- PCIe x16 slot with PCIe Gen 3 x8 signal
- 8x DIO, 2x CAN Bus
- Dimensions – 17 x 17cm (Mini-ITX form factor)
As you can see from the lack of photos of the board, development is still at the early stage, and the processor and motherboard are only expected in about 9 months (Q3/H2 2024), so I’d assume things may still change a bit, especially for the board.
But if you feel somewhat adventurous, you can already pre-order your Oasis motherboard from Arace for just $0.10 which will give you a coupon code for a 20% discount, or a starting price of starting $120. A few more details may also be found in the announcement.
