It can happen that although both cards have a sticker of X1650 one might be actually is X1600.

For this I have 2 other notes.

1. One card is labeled "X1650GT 256HM DDR3", the other is labeled
"X1650 256HM DDR3". These sticker-labels are from the vendor
instead of from resellers thus more reliable.
2. I am pretty sure both board have identical circuit board, because
even the smallest capacitors on them are located in exactly the
same place, although I could not be sure the chip being the same,
because they are beneath the fans. I am confident that any
consumer (means non-professional) would think they are the same card.
