..:: Everest ::..

The Everest results for Read, Write and Copy bandwidths all closely mirror those of SANDRA. The Lynnfield and Bloomfield results are very close to one another, while the Westmere numbers scale back by about 40% from the Lynnfield. In terms of overall memory bandwidth, the Core i5-661 is clearly hampered compared to the i5-750 and i7-870. The latency results that were given by Everest were also substantially slower (83ns vs 56ns). One important note is that Everest warned that it was not configured to optimally benchmark the i5-661, however given how the relative similarities between SANDRA and Everest, I chose to provide these results as well.

..:: Pov-Ray ::..

Pov-Ray is a popular benchmark for rendering performance. This benchmark places a good deal of stress on the computing resources and allows for an excellent illustration of relative performance amongst processors and chipsets. Performance in Pov-Ray was quite close for the Core i5-661 and Core i7-870, impressively so. Pov-Ray runs off of a single processor core, and we're seeing here the effect of Turbo Boost providing a higher operating frequency on the i5-661 and Hyper Threading providing a large boost over the i5-750.

..:: Cinebench R10 x64 ::..

Cinebench is one of the more popular 3D rendering applications used for system benchmarking. It is a very useful tool in that it allows for benchmarking on both single and multicore setups. In terms of single core performance we saw very similar performance results across all processors as was found in Pov-Ray. The Core i5-661 manages to put up nearly the same score as the i7-870, leaving the i5-750 trailing behind. Again, the benefits of Hyper Threading on the i5-661 and Turbo Boost can be seen in singe core applications. When it comes to multi-core performance, we see that the four physical cores on the i5-750 is superior to the two physical cores + Hyper Threading on the i5-661.
