My progress on real RISC-V hardware

Remember this thing? OLPC’s $100 laptop was going to change the world — then it all went wrong | The Verge. First-world do-gooders thinking they knew best what the developing world needed, and it failed spectacularly.

I actually LIVE in a developing nation. Electricity is not the bottleneck. We know how to make electricity. We know how to store electricity. Africa, in particular has skipped the whole PC-era and gone straight to cellphones; it’s called “leapfrogging”.

The bottleneck is bandwidth, not electricity.

For me riscv is hope, I don’t have access to as fulfilled programmers say “documentation” of other older processors, e.g. x86.

Riscv is hope both in microcontrollers and full processors.

Someone will say there are libraries or an Intel compiler, but I still feel alienated from documentation.

Here you are 2 sobering videos for whom who expects Risc-V platform to replace in general purpose computation the x86/ARM ones in the near future or even right now.
However promising as a development target actually not fullfill a generic usage as their performance, even their raw Hw values equals an ARM SoC, their output performance is mediocre in more comparisons.
So I would avoid from high expectations for a general daily usage - if it is not a development business, but replacement would be … for any working system on any conventional x86/ARM ones.
Especially as the existing boards specifically were built for developers :))

This should give you a better idea of performance than those synthetic benchmarks. I’d say the CPUs are already good enough for a lot of people. In terms of hardware, all we need now is standardized motherboards so that we can install an OS like on a normal PC.

Maybe the memory values ​​(amount) are too high

New CPU from the Chinese, who are strongly developing in RISC-V: UltraRISC Technology: UR-DP1000.

  • 8 cores, 2GHz
  • Compatable with some Linux distros, DEs, virtual machines, and wine.

Where can I buy it?

I don’t know where to buy the RISC-V UR-DP1000.CPU. From the OpenKylin desktop picture, It looks like it works with an ATX-sized board. I would ask the OpenKylin ppl - they seem very active: “the community has created a repository with more than 20,000 software packages, and jointly with Jianshi Technology released the world’s first RISC-V laptop DC ROMA equipped with openKylin”.

It is possible that this CPU doesn’t sell towards the consumer market. Some computer systems in mainland China are targeting government and state-owned enterprise markets only

Sorry, but I am not interested in any kind of hardware that can’t be acquired by individual person that live outside of PRC.

Why not just ask the manufacturer?

Milk-V has a board upcoming with that chip, that could be interesting to kick of more RISC-V development, also should be way more capable then anything else out there:

I just bought it.

Bit of a shame that it’s only compliant with RVA22, and not RVA23 (as Ubuntu will soon require RVA23).

How? Milk-V Titan seems not available yet, only some “coupon”.

You’re right. It’s a coupon, not the motherboard. I made a mistake, I didn’t understand properly.

Got some new nice small case for RISC-V machine. Currently use HiFive Unmatched there with Nvidia GPU, but plan to use Milk-V Titan then it will be delivered.

Milk V Titan is currently available for worldwide shipment Arace Tech

what a nice pc case

Why the COAX ports?
