Milk-V Boasts of Having "The Most Powerful RISC-V Core" in Its UltraRISC UR-DP1000-Powered Titan

RISC-V specialist Milk-V has announced another single-board computer, the Milk-V Titan, this time built around what it claims is "the most powerful RISC-V core in mass production to date" — packing eight of UltraRISC Technology's UR-CP100 cores in the form of the desktop-class UR-DP1000 chip.

"The Milk-V Titan, powered by the UltraRISC UR-DP1000 eight-core SoC [System-on-Chip] (up to 2.0GHz), is a compact mini-ITX RISC-V board," the company says of the latest entry to its growing RISC-V single-board computer stable. "It supports up to 64GB DDR4 ECC RAM, a PCIe Gen. 4 x16 slot for graphics/computing cards, and an M.2 NVMe SSD. Featuring gigabit Ethernet, four USB 3.0 ports, and ATX power support, [it] also support Milk-V BMC [Board Management Controller] remote control, [and] it's perfect for high-performance RISC-V desktops and servers."

As Milk-V says, the chip at the heart of the board is the UltraRISC UR-DP1000 — home to what the company claims to be "the most powerful RISC-V core in mass production to date," the UR-CP100. This 64-bit core implements the RV64GCBHX variant of the RISC-V instruction set architecture. It uses a four-issue superscalar microarchitecture with 64kB of instruction, 64kB of data, and 512kB of L2 cache per core plus 4MB of L3 and 16MB of LLC cache for each of the two quad-core clusters. The cores are specified to run at up to 2.3GHz, though in the Titan Milk-V appears to be limiting them to their lower base clock of 2GHz, with UltraRISC claiming a thermal design profile (TDP) of just 30W.

The board supports up to 64GB of DDR4 memory with or without error correcting code (ECC), lower than the 128GB maximum of the UR-DP1000 itself, and includes a connector for the Milk-V BMC — originally developed as a controller for the company's cluster systems. There's an M.2 connector exposing four lanes of PCI Express Gen. 4, designed for Non-Volatile Memory Express (NVMe) storage, plus a 16-lane slot for add-on boards including network cards, graphics cards, and machine learning accelerators. There's a single gigabit Ethernet port, four 5Gb/s USB 3.0 ports, and a header for a single USB 2.0 port on a case's front panel.

With eight desktop-class cores, there's no surprise to see that active cooling is a requirement — and the Titan comes complete with a compact heatsink-and-fan assembly, connecting to a pulse-width modulation (PWM) header on the board for speed control. The board is designed around the mini-ITX form factor, compatible with a range of PC cases — complete with a front-panel connector for a power switch, reset switch, and disk activity LED and support for a 24-pin ATX power connector in place of a 12–19VDC power jack at the rear. Finally, there's a USB Type-C connector providing access to a debug serial port.

On the software side, Milk-V promises the ability to install a range of operating systems including Debian, Ubuntu, CentOS, Fedora Remix, Circle Linux, and real-time operating systems including FreeRTOS and Zephyr. Better still, it has pledged to upstream patches for board support to mainline Linux by the end of next year — though it remains to be seen whether it can deliver on that promise. There's also the question of long-term support in Ubuntu, with the RVA22 profile of the UltraRISC chip falling short of Canonical's mandatory RVA23 requirement for Ubuntu 25.10 onwards.

Milk-V is taking pre-orders for the board via Arace, which is taking $5 deposits redeemable for a $50 discount off a yet-to-be-announced launch price. Additional information is available on the Milk-V website — but the company has yet to show off any images of physical hardware, relying on renders to get its message across.
