Why? For that price you get a used laptop with higher perf.

Depends on how long you want to run it and your utility costs, performance/watt is good on newer chips like these.

  I wish it were easier to quantify the energy cost of building these newer more efficient devices, as opposed to repurposing existing hardware. When you add e-waste to the equation, it gets cloudier.

    Goes back to the reduce, reuse, recycle thing... It would probably be better for the environment if we force software devs to optimize, so we could have all the modern goodies but using like 1/1000th of the energy to get there. Back in the 80s and 90s, programmers would proudly shave off kB of code and use little hacks to pull every last bit out of limited resources. Now we run like 90 instances of a browser, requiring like 2 GB of RAM for a simple chat app :D

      There is way to little environmentalist pressure on IT companies. It is like they have not realized how wasteful the IT world is.

Intel Xeon D-2700* or 1700 SoC are the preferred "low power servers" in practice. Yes, they idle at 25W, but I bet you that the Xeon D-2500 will have more performance than 10x Rasp. Pi 5. More importantly: there will be server-class features like out-of-band management/IPMI, 10Gbase-T ports, etc. etc.

  Note that this board runs RK1's (which use the RK3588 SoC), not Raspberry Pis. It burns 18.5W with CPU cores maxed out, producing 224 Gflops of compute (see: https://github.com/geerlingguy/top500-benchmark/issues/27 https://github.com/geerlingguy/top500-benchmark/issues/27). Efficiency-wise, it's a little more power efficient than at least last-gen AMD/Intel chips, and a little less than Ampere CPUs and Apple's M1. I haven't had a chance to compare to M2/M3 for power efficiency yet. The Turing Pi 2 has a BMC that allows out-of-band management, and the firmware is fairly stable at this point, and the community helped build a nice CLI for it so IMO it's even nicer (from automation/remote sysadmin aspect) than IPMI for some things. There's no remote VNC/display, but these aren't meant to have displays (even though node 1 has HDMI routed to a connector on the back). The most crippling thing for my use cases is the single 1 Gbps connection externally, and the internal 1 Gbps Ethernet switching. It'd be nice if it did at least 2.5 Gbps.

Their Github seems to suggest they're working on getting both jacks working at the same time... it's been a couple days since I last checked, so they might have it working now.

    Xeons / AMD EPYCs are measured in (low single-digit) TFlops, not GFlops. AVX512 gets places, especially with Fused Multiply-accumulate (FMA) instructions and multiple pipelines. That the thing though: TFlops is still "weak" because GPU market crushes Linpack so hard its just not comparable. But I'd assume that your typical Xeon D will run circles around these other cores watt-for-watt. Its the GPUs that Xeon D is competing with and struggling with. But if we're talking about a bunch of CPU-style compute (non-Linpack workloads), or even the occassional matrix-multiply, its hard to beat Xeon or EPYC in cost and power-efficiency. And you certainly ain't gonna beat a Xeon or EPYC with tiny ARM chips right now.
