Core i5-750 and Core i7-870 Processors Review

Cinebench 10

Cinebench 10 is based on the 3D software, Cinema 4d. It is very useful to measure the performance gain given by having more than one CPU installed on the system when rendering heavy 3D images. Rendering is one area in which having more than one CPU helps considerably, because usually, rendering software recognizes several CPUs. (Cinebench, for instance, can use up to 16 CPUs.)

Since we were interested in measuring the rendering performance, we ran the test called “Rendering x CPUs,” which renders a “heavy” sample image using all available CPUs (or cores – either real or virtual, as on CPUs with Hyper-Threading technology, each core is recognized as two cores by the operating system) to speed up the process.

On Cinebench we could see a big difference in performance between Core i5-750 and Core 2 Quad Q6600 (36.79%) and Core 2 Duo E8400 (88.05%). Core 2 Extreme QX 9770 was still faster than Core i5-750 (18.01%), probably due its higher clock rate. The new Core i7-870 was 32.14% faster than Core i5-750 and a little bit faster (6.36%) than Core i7-920, probably due to its higher clock.  Core i7-965 was 8.07% faster than Core i7-870, probably due to its higher clock. Core i7-920, which runs at the same clock rate as Core i5-750, was 24.24% faster than this processor.
