Cinebench R10 is an OpenGL 3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation tool suite used by 3D animation houses and producers like Sony Animation and many others. It's very demanding of system processor resources and is an excellent gauge of pure computational throughput.

3D Rendering

This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The rate at which each test system was able to render the entire scene is represented in the graph below.

The new Core i7-2820QM was easily the fastest machine in Cinebench's CPU test, punching up over 67% more performance than the next fastest mobile chip, the Core i7-920XM. What's perhaps more impressive is how much faster the OpenGL test ran with Intel's latest, fully integrated graphics core in Sandy Bridge. According to Cinebench, in OpenGL rendering,z the Core i7-2820QM's 32nm-built HD Graphics 3000 core is orders of magnitude faster than Arrandale's 45nm graphics core. As an aside, our Sandy Bridge mobile scores here are about 2X the performance of what we've seen from NVIDIA's 16 CUDA core-powered Ion 2 GPU.

POV-Ray Performance

Ray Tracing

POV-Ray , or the Persistence of Vision Ray-Tracer, is an open source tool for creating realistically lit 3D graphics artwork. We tested with POV-Ray's standard benchmarking tool on all of our test machines, and recorded the scores reported for each. Results are measured in pixels-per-second throughput; higher scores equate to better performance.

POV-Ray continues to highlight the new Core i7-2820QM's dominance, showing over 45% more performance versus their previous generation quad-core mobile chip in the multi-threaded workload test and over 24% more throughput in the single-threaded test.
