CINEBENCH R10

The MAXON CINEBENCH R10 is based on their MAXON CINEMA 4D software. Other than being famous for their prolific use of capital letters, MAXON is also famous for providing the useful CINEBENCH benchmark, now in its tenth release. It is fully-optimized for multi-core processing and is thus the favourite benchmark of processor companies.

CINEBENCH tests the speed of the processors in rendering a 3D scene with the option to render on a single processing core or all available processing cores. So, it's great for demonstrating the performance difference of single core processors vs. multi-core processors. We obtained the results in form of the render time in seconds. A shorter render time is always better.

The new Intel Core i7-975 Extreme Edition is the obvious leader in this test. It rendered the complex 3D scene in just 45 seconds. That's 2 seconds (4.4%) faster than the Core i7-965 Extreme Edition and 12 seconds (27%) faster than the Core i7-920.

It is interesting to note the difference in the multi-core to single-core performance ratio of the processors in this comparison. While Intel Core 2 processors have a ratio of roughly 3.5x for quad-cores and 1.9x for dual-cores, the Intel Core i7-900 series of processors all have ratios of 4x to 4.2x! That means the Core i7 processors are most efficient when all four cores are being utilized.

That is something no quad-core Core 2 processor is capable of. The quad-core Core 2 processors only have a ratio of 3.5x to 3.6x. Only the dual-core Core 2 processors, with their ratio of 1.9x, can come close to the efficiency of the Core i7 processor.

This increased efficiency can be attributed to its support of HyperThreading, which allows the Core i7 processor to process up to 8 threads simultaneously. Thus, for multi-threaded applications, the Core i7 processor is about 17 % more efficient than the quad-core Core 2 processor, and 8 % more efficient than the dual-core Core 2 processor.
