I bought HeroBox for headless Intel single core cpu applications (like prime factorization, or my planar graph playground), and am positively surprised from CPU power sofar.
I never heard HeroBox fans sofar, neither under Win10, nor under Ubuntu 22.04 Desktop, although I pushed cores with more than 10 minutes of cpuburn, see “A problem with fans” thread in this forum, I am restricted to 2 URLs as new user.
While I plan to use HeroBox mostly headless, Ubuntu 22.04 Desktop looks nice on 1368x768 HDMI monitor, after running “gnome-control-center” terminal command and correcting display resolution to 1368x768.
Performance varies from app to app. In this case, prime factorization is mostly a CPU-bound benchmark, while there are other use cases when memory bandwidth is more important. In these cases, the difference is much bigger in favor of intel core processors.
@huantx HeroBox did not start on powering off and then on.
I entered Bios and changed under Boot tab to “Power on”.
Now after powercycling HeroBox boots as soon as it gets power.
So no problem with remote headless work.
This is from a photo of Bios Screen I took when I got HeroBox:
The search for prime magic square has all primes precomputed, basically the code is a huge number of nested loops testing for a 3x3 magic square. So yes, memory is not a big problem, and therefore J4125 behaves better.
I just tested 6-coloring (planar graphs always have a 4 coloring, but 6-coloring is simple algorithm needing linear time only) on a 500,000 vertices maximal planar graph:
i7 8 seconds:
$ time ./c++_6coloring ../graphs/500000.a 2>err >> out
J4125 14.7 seconds, 83.75% slower than i7:
hermann@j4125:~/planar_graph_playground/c++$ time ./c++_6coloring ../graphs/500000.a 2>err >> out
So J4125 is worse than “60% worse than i7” before, but still better than “100% worse than i7” according the two single core performance benchmarks, and that for 168$ only:
