Cinebench R11.5 BenchmarksMaxon Cinebench is a real-world test suite that assesses the 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. Cinebench Release 11.5 includes the ability to more accurately test the industry's latest hardware, including systems with up to 64 processor threads and the testing environment better reflects the expectations of today's production demands. A more streamlined interface makes testing systems and reading results incredibly straightforward. The Cinebench R11.5 test scenario uses all of a system's processing power to render a photorealistic 3D scene, "No Keyframes" the viral animation by AixSponza. This scene makes use of various algorithms to stress all available processor cores. The OpenGL graphics card testing procedure uses a complex 3D scene depicting a car chase with which the performance of your graphics card in OpenGL mode is measured. During the benchmark tests the graphics card is evaluated by way of displaying an intricate scene that includes complex geometry, high-resolution textures, and a variety of effects to evaluate the performance across a variety of real-world scenarios.
In the CPU Single Core tests, Cinebench focuses on a single thread of processing, so all of the AMD CPU scores are based nearly completely on their clock speeds. You can see this clearly from the results if you exclude the Core i7 and i5 processors. The Core i7-920 sits about at the same point as the Phenom-II X2-560BE which runs at 3.3GHz. The similarly clocked Core i5-2500K, however, scores much higher than any CPU on the charts. This is undoubtedly due in part to the turbo boost ability of the Sandy Bridge CPU, which allows it to overclock a single core up to 3.7GHz if no other cores are active. The Phenom-II X4-975BE, while beating the Core i7-920 CPU, falls behind the i5-2500K by 37% in the Single Core test. In the Multi-Core Cinebench test the Intel Core i7 can take advantage of multi-threading so the Core i7's four cores turn into eight threads, giving it a higher score than all but the Core i5-2500K. The 2500K doesn't have hyperthreading capabilities, but still destroys even the 8-threaded Core i7-920. Since Cinebench focuses on isolating the CPU for testing, this multi-core test really shows the power of the new Sandy Bridge CPU. Gains over the Phenom-II X4-975BE are at almost 28%, with 12.5% gains over the hyperthreaded i7-920.

Either way I am most likely going to get the i5 2500k since it is very strong. Also the price is rather cheap at $211 when currently the i5 750 is $200 and the i5 760 is about $209 dollars. Since I did not upgrade following the first i series I would need to get a new motherboard anyway.Integrated graphics means little to me since as a gamer I would get a higher end GPU regardless. I just have to make sure the motherboard is p67 not H67 for overclocking and such.
Anyway nice read, thanks for the article.
