Hercules 3D Prophet 4500 64MB - KYRO II (13/15) Full Scene AntiAliasing The tile-based rendering technique also seems to benefit anti-aliasing. Like the GF2 and the RADEON, the Kyro uses the super sampling method. Instead of super sampling the entire scene, the Kyro II does its smoothing tile-by-tile, completely within the chip and its caches. According to ST Micro, this makes the additional memory transfers usually associated with FSAA a thing of the past. FSAA performance is therefor linked directly to the speed at which the chip can work on the tiles. So what does that mean in this context? Well, in the low 16Bit resolutions, we see the GTS dominate the field, with the Kyro II in second place. In 32Bit, the cards switch places, with the Kyro II now securely in first place, taking only a minimal performance hit compared to 16Bit. FSAA Benchmarks
DThe Prophet 4500 comes in first in almost all benchmarks and takes almost no performance penalty in 32Bit color. The 32MB cards are unable to use 4xFSAA in Direct3D above 1024x768-32 due to lack of memory.
OpenGL testing yields similar results. Surprisingly, the 32MB cards are suddenly able to use 4x FSAA at 1024-768. In Direct3D the NVIDIA boards would automatically default to 2xFSAA. The Prophet 4500 continues to show the better 32Bit FSAA performance, even in OpenGL. Since the final performance is strongly dependent on the chips speed, an increase in core clockspeed should result in increased FSAA performance. Read on to find out how the Kyro reacts to overclocking. |
