3D Rendering Performance

Caligari TrueSpace

TrueSpace is probably the best application out there to measure multiprocessor performance. Also, there is only a limited impact of the cache since most of the data are non-recurrent. The small performance gain we see between the QX 6850 and the QX 9650 is attributable to running the memory at lower latencies (6-5-5 vs. 7-7-7).

Vases

Adam Trachtenberg's model was rendered at 1024 x 768 with raytracing enabled and 2 x AA. The screenshot shows the leapfrogging scan lines in the case of Intel's V8 system using 8 processors.

Render Time

Render time in seconds, lower is better.

Power Consumption per Renderpass

Rendertime multiplied with the power consumption measured during the rendering. The result shows the energy efficiency for 3D rendering under full utilization of all CPU resources. Lower is better.

In a domain that was hitherto dominated by AMD's CPUs, the Yorkfield sets a new standard and does so by a landslide.
