These old cards can be a mess.
As per spec, X700 should have 400/350 stock clocks and GDDR1 memory. Usually these cards come with device ID 1002-5E4D.
As per spec, X700 Pro should have 425/432 stock clocks and GDDR3 memory. Usually these cards come with device ID 1002-5E4B.
But you also have cards like the ones you mentioned that are neither here nor there. It's really hard to say whether they are upgraded versions of X700 or crippled versions of X700 Pro (especially that drivers and stock clocks can be manipulated) so it really depends on personal view of the person in charge of hardware categories, Antinomy.
