Yeah, compatibility for x86 is much better. If you want a cheap fanless sbc-style setup then the best options today are likely Celeron N5105 or Pentium N6005 based systems (e.g. MeLE Quieter3 or Odroid-H3+). They are around $300 and far more performant and much better connectivity (i.e. they have 8x PCIe-3 lanes) vs similarly priced ARM systems. The closest ARM systems in price and performance are the new RK3588 based ones like the Khadas Edge 2 or ROCK 5B, but those really are only practical if you really need the NPU and MIPI camera inputs they provide. They carry only a minor power efficiency edge (max draw around 12W vs maybe 18W for the x86 boards), are compromised in software compatibility, and are limited in IO (i.e. either PCIe-2 only or PCIe-3 but with only 4 lanes).
