ATI 3D RagePro XL Features ? 55
5.7
Floating-Point Set-up Engine
l
The RAGE PRO XL integrates a floating-point set-up engine capable of
processing up to 1.2 million triangles per second. By off-loading the
set-up function form the CPU, allowing it to focus on 3D geometry and
lighting transformations, the RAGE PRO XL dramatically improves the
performace of the entire 3D pipeline.
l
Compared with competing first generation set-up engines which only
accept fixed-point parameters, requiring the CPU to perform
float-to-fixed conversions that can take up to 100 CPU clcoks, ATI's
floating point architecture opens the door to the highest level of 3D
performance.
5.8
125MHz SGRAM
l
Frame buffer bandwidth is another important factor affecting 3D and
2D graphics performance. RAGEPRO XL 64-bit, 125MHz SGRAM
interface delivers 1GB.s of low-latency frame buffer bandwidth.
l
It is the ideal complement to the high bandwidth AGP 2X mode
interface. By contrast, single-channel, non-concurrent RAMBUS
designs used by others are limited to 600MB/s of high-latency
bandwidth.
