Some high-performance RISC-V processors are in the pipeline for the rest of the year 2025, namely UltraRISC UR-DP1000, Zhihe A210, and SpacemIT K3. We currently have limited information about each of those processors, but let’s see what information we can gather from the web, mostly as a result of the recent RISC-V Summit in China.
UltraRISC UR-DP1000 – Octa-core 64-bit RISC-V SoC
The first SoC is the UR-DP1000 octa-core from UltraRISC (the website loads slowly, and I could not find anything about the UR-DP1000 there). It will be used in Shenzhen Milk-V Technology’s Titan mini-ITX motherboard, and Sipeed also posted the slide above on X.
Preliminary UR-RP1000 specifications:
CPU 8x 64-bit RISC-V UR-CP100 “RV64GCBHX” cores up to 2.0 GHz Two 4x core cluster design with 4MB L3 cache each, and a total of 16MB cache. SPECCPU2006 single-core INT @ 10.4/GHz; single-core FP @ 12/GHz Fully RVA22 compliant, and “Compliant with RVA23 excluding V extension.” Supports Hardware Virtualization, RISC-V RV64 ISA H(v1.0) Extension
Memory – UDIMM DDR4-3200 ECC memory support, up to 64GB
Networking – GMAC
High-speed expansion interfaces 1x PCIe 4.0 x16 2x PCIe 4.0 x4
Other I/Os – 1x QSPI, 2x SPI, 4x I2C, 4x UART, 40x GPIO, eSPI/LPC
Many features will have to rely on the PCIe interfaces, and for instance, the Titan motherboard also offers four USB 3.0 ports, which must have been implemented through a PCIe to USB 3.0 bridge. It will have UEFI firmware with support for ACPI, CPPC, SMBIOS, and the ability to boot RISC-V ISO images from Debian, Ubuntu, openEuler, Centos, Deepin, Feroda Remix, and other operating systems. The plan is also to have mainline Linux support by Q4 2026.
