As far as I know, there's still no real RISC-V equivalent to Raspberry Pi, and I think that's what early adopters want the most.
The closest thing is probably Orange Pi RV2, but it has an outdated SoC with no RVA23 support, meaning some Linux distros won't even run on it. Its performance is also much poorer than of the RPi5.
Milk-V Titan is a Mini-ITX RISC-V board that has support for UEFI with ACPI and SMBIOS, 1x M key PCIe Gen4 x16 slot with GPU support, 2x USB Type-C (though unfortunately not USB-C PD), and a 12V DC barrel jack.
To add a 2x20 pin (IDE ribbon cable) interface like a Pi: add a USB-to-2x20 pin board, use an RP2040/RP2350 (Pi Pico (uf2 bootloader) over serial over USB or Bluetooth or WiFi; https://news.ycombinator.com/item?id=38007967
The benchmark is well tuned for ARM64 but not so well adapted to RISC-V, especially the vector extensions.
You may still be right of course. The SpaceMIT K3 is exciting because it may still be the first RVA23 hardware but it is not exectly going to launch a RISC-V laptop industry.
There isn't much to tune in some, e.g. the clang benchmark.
We know that many of the benchmarks already have RVV support (compare BPI-F3 results between versions) and three are still missing RVV support.
I think the optimized score would be in the 500s, but that's still a lot lower than Pi5.
Well, today it is only Ubuntu 25.10 and newer that require RVA23. Almost everything else will run on plain old RV64GC which this board handles no problem.
But you are correct that once RVA23 chips begin to appear, everybody will move to it quite quickly.
RVA23 provides essentially the same feature-set as ARM64 or x86-64v4 including both virtualization and vector capabilities. In other words, RVA23 is the first RISC-V profile to match what modern applications and workflows require.
The good news is that I expect this to remain the minimum profile for quite a long time. Even once RVA30 and future profiles appear, there may not be much pressure for things like Linux distributions to drop support for RVA23. This is a lot like the modern x86-64 space where almost all Linux distributions work just fine on x86-64 v1 even though there are now v2, v3, and v4 available as well. You can run the latest edition of Arch Linux on hardware from 2005. It is hard to predict the future but it would not surprise me if Ubuntu 30.04 LTS ran just fine on RISC-V hardware released later this year.
But ya, anything before RVA23, like the RVA22 Titan we are discussing here, will be stuck forever on older distros or custom builds (like Ubuntu 25.04).
I'm not even sure it's just instruction support that's the problem with the RV2. I bought one since I thought it would be cool to write a bare metal os for it (especially after I found the AI results to be so bad.) But the lack of documentation has been making it very hard to get anything actually up and running. The best I've got is compiling their custom u-boot and linux repos, and even those come with some problems.
I have been disappointed with Orange Pi hardware, I am not surprised.
Seldom does an SBC vendor want to actually support their products. You get the distro they made at launch, that is it. They do no updates or support. They just want to sell an overpriced chipset with a fucked and unwieldy boot sequence.
Same thing with all the Android devices. Pick a version of Android that you like because that's what you'll have on it forever.
