    Intel Core 2 Extreme QX9770 Preview
    By Vince Freeman :  November 19, 2007

    Multi-Threaded Performance

    As we are covering multi-core processors, a more in-depth look at multi-threaded processor performance is certainly warranted - 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 is another nice showing for the Core 2 Extreme QX9770, and it easily takes the top position in our chart. Intel processors are well ahead of the AMD competition, and it's really a case of Core 2 comparisons. The 45nm Core 2 Extreme QX9650 showed a nice performance jump over the QX6850, with both clocked at 3.0 GHz. The new top score is a combination of the 3.2 GHz clock speed and the move to FSB1600. Now we'll see if Intel's latest and greatest 45nm processor can repeat the trick in the far more demanding CINEBENCH 10 benchmark.

    The CINEBENCH 10 benchmark scores are even more impressive, and the Core 2 Extreme QX9770 creates a larger gap between itself and the Core 2 Extreme QX9650. CINEBENCH 10 seems to make better use of either FSB1600 than the older benchmark, and it's another area the Core 2 Extreme QX9770 can really shine.

    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 testing was another nice surprise, and while we knew this test likes the higher core and memory speeds, it seems to make full use of faster bus speeds as well.
