Multi-Threaded Performance

Since we're now firmly in a multi-core world, in-depth evaluation of multi-threaded processor performance is required, but without the limitations of single-threaded applications or component-specific benchmarks. We offer up three different multi-threaded benchmarks: CINEBENCH 9.5, CINEBENCH 10 and WinRAR.

CINEBENCH 9.5 & 10 Performance

CINEBENCH is a performance suite, which utilizes CINEMA 4D for both CPU and video-based testing. We use the multi-threaded CPU benchmark, which processes a large, detailed image file on-screen, and displays the test results. Both CINEBENCH 9.5 and 10 dynamically shift image processing on the fly. If one core is finished its job, the program automatically segments the remainder of the image, thereby speeding up processing times considerably. The main difference between the two is the image workload, with CINEBENCH 9.5 offering a more mainstream test, while CINEBENCH 10 gives the CPU a much tougher workout.

Our CINEBENCH 9.5 benchmark testing shows the Phenom II X3 and X4 processors giving the Intel Core 2 Duo/Quad models a good run for the money. The Phenom II X3 720 makes short work of the Core 2 Duo E7300, while the Phenom II X4 810 takes a run at the Core 2 Quad Q9400. Even the powerful Core i7-920 is within reach, not finishing that far ahead of the Phenom II X4 940.

The more demanding CINEBENCH 10 benchmarking pushes the advantage in Intel's favor, and now we see the Core 2 Quad processors with a slight advantage over the corresponding Phenom II model.

WinRAR 3.80 Performance

WinRAR is one of the most popular compression programs, and it even includes an internal benchmark program that measures the performance of the RAR compression and decompression algorithm using a demanding worst-case data set. This multi-threaded test offers a data throughput rating, and while it does not relate specifically to cache or memory transfers, we have found that the overall throughput numbers do adhere closely to the overall architecture. A faster clock speed certainly helps, but the score also ties in closely with memory, cache and CPU performance.

WinRAR is another multi-threaded benchmark, and it has displayed excellent results for the Phenom II line. It's a repeat performance this time out, as the Phenom II X4 810 outperforms the powerful Core 2 Quad Q9450.
