NVIDIA's
new card is the GeForce 9800 GTX+ GPU, an overclocked 9800 GTX, but really
the 55nm refresh of the G92. NVIDIA increased default clock/shader speeds: from
675MHz to 738MHz and from 1688MHz to 1836MHz respectively. Memory speeds for
this card will be 1100MHz, similar to the existing 9800 GTX. The MSRP will be
$229, and it will hit store shelves in mid-July.
PhysX for the GeForce 9800
GTX, 9800 GTX+, and GTX 260/280 cards will be enabled by the ForceWare 177.39
driver, timed to launch with the GTX+. And NVIDIA says it will gradually
roll out PhysX support to the full GeForce 8/9 line. As the above graph shows,
GPU accelerated PhysX could offer a significant performance increase, in games
that support the technology. The UT3 PhysX map pack for example, which was used
to gather the data above, shows a major boost with GPU accelerated PhysX
enabled.
