Multi-Threaded Performance

Since it is now a multi-core world, a more in-depth look at multi-threaded processor performance is certainly warranted, 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.

The CINEBENCH 9.5 benchmarking might not look that impressive, but the Core 2 Duo E8500 is already behind the 8-ball because of its dual core architecture. Its ability to pass the 1K mark, and actually compete with baseline quad core processors, is incredible and really shows off how powerful a 3.16 GHz Wolfdale core can be.

CINEBENCH 10 benchmarking is even more demanding, and here the quad core processors really start to break away. The Core 2 Duo E8500 is obviously at the top of the dual core class, but it can no longer compete with even the Core 2 Quad Q6600.

WinRAR 3.71 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.

The WinRAR results are also exceptional for a dual core processor, but the multi-threading engine of WinRAR again gives the advantage to the quad core models.
