you need to have a tumor in the brain to fork out $1,500 to pay for a half baked dev machine that just deliver 1/10 of the performance of an intel/amd server processor.

The point is to use this as a RISC-V development machine, not to get performance parity with x86.

  If you can't even get decent performance out of such so called "development machine", what is the point using it rather than just run qemu? If it is not about performance, what is the point having multiple cores in the first place? If the machine is so slow to the extent that you can be running 10x slower than an AMD server processor 2 generations behind, do you actual consider such environment to be realistic? Everything is about performance.

    Core for core it's as fast as or faster than QEMU running on current x86. An x86 machine with 64 cores costs $5000 just for the SoC, probably $7000 for a complete machine. This is $1500 for motherboard + CPU, $2500 for a complete system with 128 GB RAM.

and that's only the board and the cpu. the case costs $2,500

  Yeah… I’ve never seen RGB coolers that expensive.

  it is pretty much an online free IQ test.

  That includes 128 GB of RAM, which costs $400 to $500. And a 1 TB SSD, about $100 for a good one. And a video card. Cases and power supplies aren't free either. If you bought just the motherboard with CPU and built up something with equivalent specs yourself, from new parts, you might end up at less than $2500, but it won't be by much.
