Interesting page. But I think that the benchmarks need to
be taken with a grain of salt. For example, the SU2300
seems to be twice as fast only in the single-threaded
benchmarks. In the multi-threaded benchmarks, the SU2300
is only a little faster (10 - 20 percent).
The Atom will be more than enough for me. There are several
fanless (!) mainboards with a dual-core Atom (330 or D525)
that have the ION chipset with full-HD MPEG acceleration
via VDPAU. I'll probably combine that with an SSD in order
to get a completely silent system without any moving parts.
Best regards
Oliver
PS: I'm not interestd in VDR at all, I don't want to record
anything. Also, I don't have DVB-anything. In my case, the
box will be purely for playing media and for web surfing.
