# SpacemiT K3

12 Hacker News commenters recommended SpacemiT K3 and 2 criticized it, November 2025 to November 2026. It was recommended in 8 of 13 months. It meets the Hacker Approved badge rule.

**Verdict:** Fast enough for everyday desktop use, with RVA23 vector support and strong multi-core speed. Critics say it costs too much for what it delivers.

## Why people recommend it

- Strong multi-core speed beats Pi (5 comments): "It's quite pleasant, and if I use all 16 cores (8x X100 and 8x A100) then it builds a Linux kernel almost 3x faster than my one year old Milk-V Megrez" ([source](https://news.ycombinator.com/item?id=46894034)) "It's quite pleasant, and if I use all 16 cores then it builds a Linux kernel almost 3x faster than my one year old Milk-V Megrez" ([source](https://news.ycombinator.com/item?id=46865884)) "It has single core performance about the same as a Pi 4 but with multi-core performance of more than double the Pi 4." ([source](https://news.ycombinator.com/item?id=46844815))
- RVA23 and SIMD vector support (4 comments): "If you have a higher budget, I'd recommend the SpacemiT K3, which is the fist RISC-V SBC with RVA23 support." ([source](https://news.ycombinator.com/item?id=48917887)) "SpacemiT K3 based machines are probably your best bet when it comes to RISC-V processors with SIMD support" ([source](https://news.ycombinator.com/item?id=48917743)) "The SpaceMIT K3 is exciting because it may still be the first RVA23 hardware" ([source](https://news.ycombinator.com/item?id=46709424))
- Fast enough for everyday computing (4 comments): "These won't be the fastest CPUs available, but they'll meet the "fast enough" criteria for many uses and users." ([source](https://news.ycombinator.com/item?id=47639301)) "They are quite close in feel for general use, web browsing, code editing, watching YouTube etc." ([source](https://news.ycombinator.com/item?id=48207111)) "dramatically faster than earlier chips, enough for most people's everyday computing needs" ([source](https://news.ycombinator.com/item?id=47568917))
- Much faster than K1 predecessor (2 comments): "in fact significantly faster than the previous generation K1 chip" ([source](https://news.ycombinator.com/item?id=48498901)) "The SpacemiT K3 is 4 times faster than the K1 for example." ([source](https://news.ycombinator.com/item?id=49326099))
