I would never say "ignore the photo".  I would say take the entire article in
context
and if there appears to be an accurate text review, with a photo that seems
"odd" then
so what?  In this case there are several plausible explanations for a
doctored-up CPU
photo.  Any could be right.  All could be wrong...

I don't disagree.  However, I generally take things at face value if they are
from a
reputable source.  And I generally ignore them if they are not (the comment
about
Leko from Sam Sloan is an example of the latter case).  THG has always seemed
legit to me, and AMD provides them with information and pre-production hardware,
which means AMD must think they do reasonable reviews or they would "pull the
plug" on them and not give them stuff to review prior to it being available to
the
public.

That at least suggests (to me) that THG is reasonably accurate.  Do they make
mistakes?
They _must_ as everyone does.  But does a mistake make them dishonest?  I don't
believe
so...

True, but THG gets hardware from AMD, Intel, even HP and others.  If they
are too biased some of those sources would dry up quickly...

You'd be wrong, because Crafty is in _the_ benchmark that everyone uses to
compare
raw CPU power.  I've talked to _every_ chip manufacturer over time, helping them
understand the code, helping them track down compiler bugs with high levels of
optimization, etc.  They aren't paranoid about it, but they do take notice since
chess
is "in the mix."

However, THG is not about chess anyway, it is about hardware information and
comparisons
to show what is what and when it is/isn't...
