SiSoft SANDRA XII 2008 Bandwidth Performance
SiSoft SANDRA XII 2008 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.
SANDRA XII 2008 includes a range of memory and cache-related benchmarks, and definitely makes a great fit for our high-end processor testing. Both of the new Phenom models get off to a better start in this benchmark, and the Phenom X4 9950 BE is the first processor to surpass the 10K mark in this test. Even the Phenom X4 9350e does very well in this benchmark, managing to outperform the 2.4 GHz Phenom X3 8750.
The SiSoft SANDRA XII 2008 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.
The Cache & Memory benchmark gives a nice boost to all the quad core processors, and although the Phenom X4 9950 BE still lags behind the Intel Core 2 Quad models, it does make up some ground. The 2.0 GHz Phenom X4 9350e again outperforms the 2.4 GHz Phenom X3, while leaving the Athlon 64 X2 6000+ in the virtual dust.
SiSoft SANDRA XII 2008 incorporates a set of multi-core benchmarks that test the inter-core bandwidth, processor affinity and latency of today's top-end CPUs. The first test measures the efficiency of the inter-connect bandwidth, and determines overall bandwidth available between processors. The Phenom still scores extremely low in this test, and we continue to hope this is a software anomaly.
