    Intel Core i7-965 XE & Core i7-920 Review
    By Vince Freeman :  November 3, 2008

    SiSoft SANDRA 2009 Bandwidth Performance

    SiSoft SANDRA 2009 is a very popular system benchmark, and each revision sticks to its roots and supplies a wide range of individual benchmarks and system utilities. These tests include processor, system, network, and hard drive benchmarks, along with many other performance metrics. The memory bandwidth test is the most popular section of the SiSoft SANDRA benchmark suite, and it highlights the potential performance levels of the CPU-memory subsystem. As the Integer and FPU memory bandwidth scores are quite similar, we are only including the first one in our benchmark testing.

    The memory bandwidth test in SANDRA 2009 is the first entirely memory-specific benchmark so far, and it will be exciting to see what the Core i7 and its triple-channel memory architecture can really do. Needless to say, the results are way past impressive, and quickly move into the real superlatives. There is absolutely no contest between the Core i7 and any of the Phenom or Core 2 models, and Intel has definitely hit a home run on the memory architecture side of things.

    The SiSoft SANDRA 2009 Cache & Memory benchmark goes well beyond memory performance, and measures the bandwidth of the combined processor cache and memory subsystem. This test can show off the architectural advantages of each processor, as well as the benefits of larger and faster L1/L2 data caches, and help give us an overall view of how the processor and memory match up in high-speed data transfers.

    Chock up another resounding win for the Core i7, as the Cache & Memory benchmark shows all three processors with record-setting bandwidth results. Once again, these are very impressive scores, and not only highlight memory enhancements, but also the benefits of the new core design.

    SiSoft SANDRA 2009 incorporates a set of multi-core benchmarks that test the inter-core bandwidth, processor affinity and speed of today's top-end CPUs. This measures the efficiency of the inter-connect bandwidth, and determines overall bandwidth available between processors.

    As the Core i7 is a true multi-core design, this benchmark shows off the benefits of going that route, and linking the individual cores internally, rather than joining multiple CPUs on a chip substrate. These results are right up there with the memory bandwidth scores, and represent a completely new level of multi-core performance.
