Chinese Startup Unveils The First RISC-V Based AI CPU, Powers The K1 Domestic Laptop

AI hype has made its way into the RISC-V architecture, as Chinese startup SpacemiT has unveiled a new custom CPU targeting AI computing.

SpacemiT's latest K1 CPU targets the hyped-up AI compute segment with RISC-V magic.

Given the state of modern-day CPU markets, dedicated AI engines embedded in processors have been a hit for firms like Intel, with their Meteor Lake lineup. With this, many firms have jumped on the bandwagon, one of them being SpacemiT. The firm has revealed its latest SpacemiT Key Stone K1 processor, which is reportedly based on a new RISC-V AI standard, which we've seen hit the markets for the first time. Let's take a quick look at what this optimized RISC-V has to offer its potential users.

As revealed. Jason Will, the octa-core K1 processor is targeted to showcase the performance of the RISC-V architecture in the AI ​​segment. Intriguingly, RISC-V chips are known to be 1.5 times ahead of current ARM chips when it comes to the deployment requirements of AI algorithm models, further fueling its adoption.

Stacking SpacemiT's K1 processor against the ARM Cortex-A55, the RISC-V camp manages to deliver 130% higher single-core performance, with roughly 60% to 80% lower power consumption. The results are truly surprising because they show that RISC-V can play a dominant role, provided the architecture manages to gain mass appeal.

To provide a proper ecosystem, SpacemiT has also revealed its SpacemiT Muse Book 1st Gen, which features the company's own K1 processor. The notebook reportedly features a custom Bianbo OS, with support for 16 GB of LPDDR4X memory. Below are the full specifications, compiled by CNX Software:

  • SoC – SpacemiT K1 is compatible with octa-core X60 RISC-V core RVA22 and 2.0 TOPS AI Power.
  • System memory – Up to 16GB 32bit LPDDR4-2400MT, 32bit LPDDR4X-2666MT
  • Storage
    • 32GB eMMC flash (default), option up to 128GB
    • M.2 (PCIe 2.1 2x) socket for NVMe SSD up to 1TB
    • microSD card slot
  • Display
    • 14.1-inch IPS display with 1920×1080 resolution, 60Hz refresh rate
    • 72% NTSC (≈100%sRGB) color gamut
    • 250 nits brightness
  • Networking – WiFi 6 module based on RTL8852BE
  • Power supply – USB PD 3.1 Type-C port (65W power adapter)
  • Dimensions – 322.6 x 209.2 x 17.8 mm
  • The weight – 1.36 kg
  • OS: Bianbu OS by Debian, Ubuntu, Linux
  • Browser: Chromium

It's too early to say whether RISC-V-based AI processors will start to become hits, but based on the implementation by IntoTimeSpace, they certainly look worthwhile. Since the MuseBook is an early product, we may not see it launch in global markets, but the firm has plenty planned for its users, including a dedicated mini PC.
