Odroid H4 single board x86 computer - three new models 

Yes, will be interesting to see how they perform.

I am guessing the DDR4 dual channel is faster, but would like to see this tested. However, the N97 CPU may be more important.

Yes those are the sizes of the H2 & H3 models, the H4 needed to be larger to accommodate the extra display port and Sata ports. Hardkernel appear to have decided that multiple 2.5Gb ethernet ports was their favoured direction. You can always add WIFI using one of the USB ports. Having WIFI on the H4 base model would have been a nice touch using the board space freed up by not having SATA ports on it. But as that would have meant a board redesign, perhaps we'll need to wait for the H5.
