With all its cooling solutions stripped off, this is how the
card looks like. From this view, we can see that this GTO² shares the exact PCB
design as those higher end X850XT cards.


As said before, Sapphire’s GTO² is the only X800GTO that
actually comes with the R480 core, and boasts full 16 pipelines straight out of
the box. As from our knowledge, these cores are likely down clocked X850XT
cores.


While all other X800GTOs we’ve reviewed before spots 2.0ns
GDDR3 memory, the Sapphire GTO² actually comes with faster 1.6ns GDDR3 RAMs.
Although the default memory clock speed is only at 980MHz, such 1.6ns GDDR3 RAMs
could run a theoretical maximum clock speed of 1250MHz.


The cooling solution for this card is rather puny from it’s
looks. But however, the fan on the card is rather powerful (albeit slightly on
the nosier side). Also, a copper slab is located right at the center of the
heatsink, which sits directly on the die of the core. With this design, it would
ensure better heat dissipation for the core. However, we certainly hope for a
slightly beefier heatsink for this enthusiast geared card.
