| Sapphire RADEON X850XT Platinum Edition AGP AGP Strikes Back | |
|
(Review by MS, May 30, 2005) |
| GeForce 6800GT At: |
X2-Rolling Demo
In addition to the default mode, X2 supports antialiasing and shadows, both of which are quite heavy on the GPU, using extra memory as well as the shadow buffers introduced e.g. on the Ti series introduced at the end of the GeForce3 production cycle. Admittedly, volumetric shadows are standard features of any current midrange graphics adapter, nonetheless, the rendering of shadows is still very GPU-intensive.
No AA
We have seen in the past on numerous occasions that one of the critical limits of X2 is the system memory bandwidth. For example, the Biostar IDEQ200 with its system memory problems was choking on this particular benchmark. Likewise, it is conceivable that the VIA chipset may be somewhat of a hindrance here, or else, it could be in fact the AGP interface that is holding back the RADEON X850XT PE, despite its nominally greater horse power.
AA + Shadows
With all eye candy enabled, the X850XT Platinum Edition manages to get a honorable second place, and almost beats the SLI configuration at 1600 x 1200 pixels
