There is solid hardware, it just not standard hardware for consumers. RVV support in software is already good and there are already many commercial chips. > I bet many of its instructions will be micro coded since they aren't very useful for compilers anyway I have listened to a lot of the talks about RISC-V and many about Vector extension, and micro-coding was barley mentioned. What is more common is that people don't implement all the instructions in academic settings. > Specifying standards for the future before you have working prototypes is very (ahaha) risky. Absolutely nothing is standardized before hardware implementations exist. In fact, for Vector there was a first generation of the 0.7 that saw limited commercial use and far more more for the RVV 1.0 version.

I looked at RISC-V SoCs last year and I couldn't find anything at all with support for RVV. Just a lot of "coming soon", "in progress", and "preorder now". Maybe the situation has improved since then.

  When last year? The CanMV-K230 has RVV 1.0 and shipped in November 2023, just two years after RVV 1.0 was ratified. So "nothing at all" was already false before January 1 last year. The BPI-F3 (8x X60 cores with 256 bit VLEN RVV 1.0) was announced in February 2024 and shipped in May. The Lichee Pi 3A and Milk-V Jupiter with the same SoC were not far behind it, and the MuseBook and DC-Roma II laptops were not far behind them. We now also have the Orange Pi RV2 with the same SoC for $30 (2 GB RAM) to $50 (8 GB) It's probably going to be a while before we see the next generation but there are half a dozen different machines available with the current best mass-production RVV 1.0 chip.
