Thanks for interesting links, especially https://www.sophon.ai/product/introduce/pioneerBoard.html https://www.sophon.ai/product/introduce/pioneerBoard.html. I would like some day to be able to buy a microATX or Mini-ITX RISC-V board at a similar price to a board with an integrated x86-64 CPU. > Rich ecological support It took me a moment to realize that what the manufacturer meant was not "we're green" but "this has an ecosystem". :-)

  > I would like some day to be able to buy a microATX or Mini-ITX RISC-V board at a similar price to a board with an integrated x86-64 CPU. It's not like 12 or 16 core (P core) x86 boards and CPUs that would be comparable to this machine for highly parallel tasks are cheap. I paid $4500 for my 32 core Threadripper with 128 GB RAM in 2019. A quick look on Amazon shows Ryzen 9 7900 computers are $2k with only 32 GB RAM. 7900x and 7950x machines are even more. I just checked out the LLVM source code on the SG-2042. I'll see how build times compare to my Threadripper and M1 machines and report back.

    I didn't clearly explain what I wanted, sorry. I agree that similar hardware isn't cheap. It also applies to other architectures. For instance, according to https://www.tomshardware.com/news/ampere-64-core-arm-workstation-runs-windows https://www.tomshardware.com/news/ampere-64-core-arm-worksta..., > ... for now, Ampere's AADP workstation is available for orders starting at $3,250 for a 32-core version with 32 GB of DDR4 and $5,658 for a 128-core version with 128 GB of memory. Meanwhile, the devkit itself starts at $2,003. What I meant was that I'd buy a RISC-V equivalent of https://www.asrock.com/mb/Intel/J5040-ITX/ https://www.asrock.com/mb/Intel/J5040-ITX/ (a random popular example): an under $200 motherboard with a built-in low-end desktop CPU, usually quad-core. With good Linux support, I'd use it to upgrade some Core 2 Duo and similar PCs while keeping the same case, PSU, storage, GPU (if possible and practical), and peripherals.

      >I'd buy a RISC-V equivalent of A new SiFive devboard is due this summer. Note that while each of their devboards has been cheaper than the previous one, but I do not expect it to be under $300. It might even cost a couple hundred more. They do include RAM instead of socketing it, so that makes up for some of the difference. The boards so far use standard smaller ATX form factors. IIRC, new board is meant to be based on P550 CPU, which still doesn't have V extension, so I will personally skip. The ratified V specification is about the minimum I want if I am going to spend more than $150. Right now, VisionFive 2 from Starfive and the newer LM4A stuff from Sipeed are about as good as it gets. During the second half of the year, new options will appear. Next year, there's a lot that we already know of that will happen, like Tenstorrent Ascalon, competitive with Zen5.

      It's hard to find good benchmarks comparing them, but the J5040 looks to be between 10% and 30% faster than the 2.3 GHz Arm A72s in the Kirin 950. The TH1520 SoC used in the Sipeed LM4A module / Lichee Pi 4A SBC (and others to be announced soon) has C910 cores which are very comparable to A72. The chip is spec'd for 2.5 GHz but in this application it is derated to 2.0 GHz, presumably due to (lack of) cooling. Once full software support arrives, these RISC-V machines should be hard to tell from the J5040 without running them side by side. There are much faster RISC-V machines coming this year, but I don't think you're going to be able to buy them for $119. Probably $500-$1000.

I'd love to purchase a handful of Ox64s from Pine64, alas still no way to do that from the EU without inflating the price to 3x-5x after shipping and taxes. So far it seems the best Risc-V option is the (not Linux capable, though) ESP32-C3 board from Olimex. https://www.olimex.com/Products/IoT/ESP32-C3/ESP32-C3-DevKit-Lipo/open-source-hardware https://www.olimex.com/Products/IoT/ESP32-C3/ESP32-C3-DevKit... (more options welcome!)

  It is already possible to get ESP32-C6. There's some devboards in aliexpress. VisionFive 2 is also easy to purchase there, as several stores carry it.

  > I'd love to purchase a handful of Ox64s from Pine64, alas still no way to do that from the EU without inflating the price to 3x-5x after shipping and taxes. I'm not sure how you figure that. The site will unfortunately only allow you to add 10 Ox64 to your cart. That's $80 for the one with bigger flash. Adding my New Zealand address, "Standard Shipping Method" is $11.99. WIth such a small shipment there won't be NZ tax, but assuming for some reason it did get added, that would be 15% of the total including shipping, so $13.80, making a total of $105.80. That is 1.32x the advertised price. I get the same shipping price when I enter Germany as my address. I understand you have higher taxes there, but surely not THAT much higher?
