application compatibility for all DirectX® 10.1
applications. Microsoft® DirectX® 10.1 games, with
stunning 3D graphics and shading
effects.
Shader
Model 4.1 Shader Model
4.1 adds support for indexed temporaries which can
be quite useful for certain tasks.Regular direct
temporary access is preferable is most cases. One
reason is that indexed temporaries are hard to
optimize. The shader optimizer may not be able to
identify optimizations across indexed accesses
that could otherwise have been detected.
Furthermore, indexed temporaries tend to increase
register pressure a lot. An ordinary shader that
contains for instance a few dozen variables will
seldom consume a few dozen temporaries in the end
but is likely to be optimized down to a handful
depending on what the shader does. This is because
the shader optimizer can easily track all
variables and reuse registers. This is typically
not possible for indexed temporaries, thus the
register pressure of the shader may increase
dramatically. This could be detrimental to
performance as it reduces the hardware’s ability
to hide latencies. OpenGL 2.1® Optimizations and
Support Ensure
top-notch compatibility and performance for all
OpenGL 2.1 application.
ATI CrossFireX Upgrade to even greater 3D performance
quickly and easily thanks to plug-and-play ATI
CrossFireX multi-GPU
technology.
PCI-E 2.0 PCI Express® 2.0 –Now you are ready
for the most demanding graphics applications
thanks to PCI Express® 2.0 support, which allows
up to twice the throughput of current PCI Express®
cards. Doubles the bus standard's bandwidth from
2.5 Gbit/s (PCIe 1.1) to 5
Gbit/sec.
HDCP
Support High-Bandwidth
Digital Content Protection (HDCP) is a form of
copy protection technology designed to prevent
transmission of non-encrypted high-definition
content as it travels across DVI or HDMI digital
connections.
HDMI Ready High Definition Multimedia Interface
(HDMI) is a new interface standard for consumer
electronics devices that combines HDCP-protected
digital video and audio into a single,
consumer-friendly connector.
