how hard would it be for a bunch of semiconductor / cpu designers / cs students to team up and release a nice open hardware so that we can forget about PRISM and the likes ?
And yet, making the actual switch is a tremendously difficult task. On the software side alone, it requires recompiling every application you want to run on your platform. That doesn't even touch the cost of rolling the actual hardware. There are more than a few examples of this: Intel's Itanium, Oracle's SPARC, Berkeley's MIPS, Transmeta's Crusoe, etc. Sure, these all had niches (embedded systems, research hardware, a few high-end servers) -- but breaking out into the mainstream (a.k.a. like x86-64 and ARM/ARM64) is damn near impossible.
- Less bugs
- Potentially better applications since the lower layers are stable and don't require you to fight it (as an example, pre vulkan drivers were hell, linux software has to circle around that)
Nobody expects RISC-V to beat i7 or Ryzen in any benchmarks.
IMO its purpose is to be the in hardware what GNU/Linux was in software.
edit: GNU/Linux, not just Linux :)
Crusoe and ARM were not about the promise of better performance, but of being much more energy-efficient for the intended purpose (though since a few years ARM tries to get into a (more) high-performance field).
What I wanted to say is that the major selling point of RISC-V would be its open-ness rather than anything performance (or power) related. In that respect it has already captured the attention of interested parties, regardless of that the actual performance will be.
