ATI CrossFire Technology
ATI’s CrossFire technology drives your PC to a new peak of per-
formance. By connecting a Radeon CrossFire Edition graphics card
and a standard PCI Express graphics card, the power of these
multiple GPUs (Graphics Processing Units) within the system will
accelerate your gaming performance and improve image quality.
How CrossFire Works
CrossFire’s key objective is to maximize the speed of a multi-GPU
system. This is achieved by dividing the rendering workload to each
of the two GPUs. When each GPU has completed its assigned tasks
for a given frame, the Compositing Engine on the CrossFire Edition
graphics card combines the results from each GPU (according to the
selected operating mode) then sends the final frames out to the
display device. The result will be a complete frame rendered at up to
twice the performance of a single graphics card.
Features
Regardless of the type of operating mode used, the completed
frames from both GPUs are sent to the Compositing Engine on the
CrossFire Edition graphics card, which then sends them on to the
display device.
•
Supertile Mode
Supertiling divides your screen image into subsections like “tiles” in
alternating tile pattern such that half of the tiles are assigned to
each of the two GPUs.
•
Scissor Mode
In Scissor mode, each frame is split into two sections, either
horizontal or vertical, with each section being processed by one
GPU.
•
Alternate Frame Rendering (AFR)
In AFR mode, all even frames are rendered on one GPU, while all
odd frames are rendered on the other.
