CINEBENCH 11.5 Benchmarks
CINEBENCH is a real-world cross platform test suite that evaluates your computer's performance capabilities. CINEBENCH is based on MAXON's award-winning animation software CINEMA 4D, which is used extensively by studios and production houses worldwide for 3D content creation. MAXON software has been used in blockbuster movies such as Spider-Man, Star Wars, The Chronicles of Narnia and many more. The CINEBENCH benchmarks tests both CPU performance (with single- and multi-threaded rendering tests) and Open GL graphics performance with an animated car chase scene. Note that CINEBENCH scores are only valid when compared against scores produced by the same version of CINEBENCH.
CINEBENCH CPU Test
CINEMARK's CPU test renders a photorealistic, if abstract, scene. The test comes in two versions: one that uses all cores and threads possible, and another that's restricted to a single core. The test results are abstract numbers that are only useful for comparison against other systems in CINEBENCH 11.5 tests.
In the multi-threaded test, we can see that four physical cores, even at a significantly lower clock frequency, trumps two physical cores with Hyper-Threading, as the Core i5-750 turns in about 30% better performance than the Core i5-661 BX80616I5661. The single core test with each processor at its stock frequency is a wash, with identical scores for each processor. I'd have expected the Core i5-661 to win here due to its significantly higher clock, but perhaps its slower memory subsystem held it back. Overclocking the 661 to 4.6GHz enables it to eke out a narrow win in the multi-threaded test and almost 50% better performance in the single-core test.
CINEBENCH Rendering Test
This procedure uses a complex 3D scene depicting a car chase which measures the performance of a graphics card in OpenGL mode. The performance depends on various factors, such as the GPU processor, but also on the drivers used. The graphics card has to display a huge amount of geometry (nearly 1 million polygons) and textures, as well as a variety of effects, such as environments, bump maps, transparency, lighting and more to evaluate the performance across different disciplines and give a good average overview of the capabilities of your graphics hardware. The result given is measured in frames per second (fps).
For this test, the Core i5-750 wasn't included. I tested i5-661 with its integrated GPU at both stock and overclocked frequencies, as well as with two discrete graphics cards, an NVIDIA 9400GT and an NVIDIA GT240 (GDDR3 version).
Intel's previous GMA integrates graphics solutions don't have a great reputation among gamers, and these results are why. A feeble 1.92 frames per second at the stock clock can be stretched to 2.58 frames per second at the overclocked level, even a 2008-vintage 9400GT budget card, currently available for as little as $42, provides more than twice the performance. A GT240 provides about 8 times the frame rate of the overclocked 661.
