I thought we were getting close to Pi4 speeds with the latest stuff from SiFive and there's some GPU support.

  You should be looking at Rockchip's stuff if you're thinking about both hobbyist grade and industrial use. The RK3588 is still slightly ahead of the Pi 5, and several orders of magnitude above what RISC-V SBCs can deliver. Software-wise, RISC-V is way behind as well.

    Well, for industrial use I love the documentation and support of Raspberry Pi, unless you specifically need performance not available on raspberry pi.

    >The RK3588 is still slightly ahead of the Pi 5, and several orders of magnitude above what RISC-V SBCs can deliver. Not that many orders of magnitude. There's RISC-V hardware (actual boards for sale) that's faster than RK3588 (thus RPi as well) coming in 2024. This includes the SG2380 Oasis board[0] in 10 months, and a possibly earlier JH8100-based visionfive 3 board. And we aren't even talking about large implementations like Tenstorrent Ascalon (expected to be competitive with Zen5, M4). 0. https://forum.sophgo.com/t/about-the-sg2380-oasis-category/359 https://forum.sophgo.com/t/about-the-sg2380-oasis-category/3...

  Wow, has it been that long already. I'm getting old!

  The acceleration is unlike anything ARM has ever had. x86 ARM RISC-V Introduction 8008 (1974) ARM1 (1985) Raven-1 (2011) first OoO NexGen NX586 (1994) ARM A9 (2007) BOOM (2015) first multicore AMD Athlon X2 (2005) Nvidia Tegra 2 (2010) EOS16? (2012) first 64-bit AMD Athlon64 (2003) Samsung Exanos 5 (2013) Western Digital SweRV? (2017?) Bleeding Edge -- Apple M1 (2020) TBD (Tenstorrent Ascalon 2024?) Catching up is faster than doing something the first time (and it's even easier if you don't have loads of legacy edge cases slowing down progress). x86 was 20 years to OoO, ARM was 22 years, and RISC-V was just 4 years. x86 was 31 years to dual-core, ARM was 25 years, and RISC-V was just 1 year. x86 was 29 years to 64-bit systems, ARM was 28 years, and RISC-V was at most 6 years. ARM took 35 years to catch up to x86. RISC-V seems set to do that in 13-14 years (if you only start counting when RISC-V had privilege systems, that's like 5-6 years and if you only count since vectors were added, it's just 3-4 years. Put everything on a graph and RISC-V is blowing the doors off with how fast it has gone from unknown to next-gen tech.

    While I don't think your assessment is inherently wrong, part of that I think is that fabbing custom silicon is easier than ever before. Don't get me wrong, being open is doing wonders as well but just in general, nowadays fabbing ASICs (and the experience that goes with it) is so much more accessible to smaller, less risk averse players than when ARM (or x86) really started getting big.

      Simply put: technology advanced to superscalar, OoO cores & 64 bit multi-core cpus. These advancements took decades to pan out. Both x86 and ARM had to 'ride the wave' when that tech came along. RISC-V otoh can pick up the result of those advancements, piece it together for a new ISA, and go. No waiting-until-tech-advances other than the wait for design work & prepping those designs for mass-production. Both of which can take considerable time. But not decades.
