Got MilkV? Got drama
The MilkV Jupiter 2/SpacemiT K3 (RISC-V vector compute)
This tiny computer had fans cheering, skeptics groaning, and one big AI brag under fire
TLDR: The MilkV Jupiter 2 is turning heads because it makes an unusual new kind of chip look almost ready for normal people, not just tinkerers. But commenters are fighting over whether its AI claims are impressive or overhyped, with some bragging about success and others roasting its weak memory speed.
A new little desktop called the MilkV Jupiter 2 is being pitched as the first RISC-V board that feels like a real product instead of a hobby science experiment—and that alone had commenters leaning in. The review praised the tidy metal case, lots of memory, fast networking, and the surprising idea that this underdog chip family might be more exciting than the usual options right now. But the comments? That’s where the real popcorn started flying.
The biggest drama centered on the board’s wild AI promises versus messy reality. The official hype talked up huge chatbot-style models running fast, but the reviewer said real-world use hit a wall much earlier. That instantly split the crowd: one commenter basically went, “uh, actually, I’m running a much bigger model on mine,” while others side-eyed the numbers and zeroed in on the weak point they thought could sink the whole thing—memory speed. One particularly savage comparison dragged in the Pentium 4, a famously heat-happy old chip, just to say this shiny new “AI” machine might be lagging behind a computer from the early 2000s in one key area. Ouch.
There was still plenty of nerd joy. One commenter loved the weird unlock process for some of the cores, joking that it feels like driving the chip like a graphics card command queue—which is exactly the kind of delightfully chaotic sentence that makes hardware threads feel like a secret club. Meanwhile, practical shoppers showed up with the eternal mood-killer question: is the 32GB version sold out, and can you even upgrade it? Short answer: sold out, and probably no. So the vibe is clear: promising, a little strange, maybe groundbreaking, and absolutely not escaping the comment-section court of public opinion.
Key Points
- •The article reviews the MilkV Jupiter 2, a Pico-ITX RISC-V single-board computer based on SpacemiT’s K3 SoC.
- •The tested configuration includes 16 RISC-V cores split between 8 A100 cores at 2 GHz and 8 X100 cores at 2.4 GHz, along with 32GB RAM and 128GB UFS.
- •Hardware features listed include Wi‑Fi 6, Bluetooth, 1 GbE, 10 GbE SFP+, M.2 expansion, USB-C PD power, DisplayPort, and an IMG PowerVR GPU.
- •The author says the A100 cores differ from the X100 cores by adding extended vector instructions, transactional memory, and AI-related features.
- •The article notes vendor claims of 60 TOPS and 30B-model support, but reports practical testing reached a hard limit around an effective 3B model size.
