| ATi FireGL X1 DX9 Capable for OpenGL | |
| (Review by MS, Oct 15, 2003) |
Phoenix
Phoenix simulates pyrotechnics in software. Rendering is done almost exclusively on the level of the GPU or VPU or whatever it is called with very little CPU influence. We rendered the Phoenix V2 sequence using 55 sprites and polygon antialiasing to max out both the local frame buffer utilitzation and the actual workload on memory and VPU for 200 frames. Phoenix is a benchmark that requires large amounts of onboard memory and that is where even the Quadro4 has an advantage over the FireGL X1 since it can dynamically allocate any amount within its frame buffer to either texture or geometry, whereas, to the best of our knowledge, the FireGL-X1 uses fixed size frame buffers (but we have not heard back from ATI on that matter yet)
Rendering time in seconds, lower is better. One thing about our results here is that the Quadro4 980XGL received a boost in performance since our last review that we cannot explain. In our review of the Wildcat VP990, the Quadro4 took a little over 14 min to do the same that it accomplished now in 8 1/2 minutes. To the best of our knowledge, we were using the exact same configuration and settings but try as we might (and I repeated this about a dozen times), it was not possible to extend the runtime beyond 8 min 30 sec. At the identical settings, the results for the FireGL match benchmarks supplied by Creative Labs but since we had to return the Wildcat, there is no chance to verify that the VP990 scores would stay the same. We believe they would. Bottom line is that the FireGL X1 is falling behind by quite a margin.
