SiSoftware, founded in 1995, is one of the leading providers of computer analysis, diagnostic and benchmarking software. The flagship product, known as “SANDRA”, was launched in 1997 and has become one of the most widely used products in its field. SANDRA is used by almost 400 world-wide IT publications, magazines, review sites to analyze the performance of todays computers.
Multi-Core Support: SMP (multi-processor) and SMT (multi-threading/Hyper-Threading) support has been added for future AMD and Intel CPUs. The benchmarks have been optimized to schedule the optimum number of threads on the optimum (virtual) CPU on both multi-core and Hyper-Threaded computers.
The paair of Intel Xeon X5365 processors on the Intel S5000XVN workstation board make short work of the other processors that we compared it to. The AMD QuadFX platforms just can’t compete with the pair of quad-core Xeon processors. With the QuadFX platform running two dual-core processors and the V8 system running two quad-core processors could inter-connectivity be causing some of the performance differences? Let’s take a look at multi-core eddiciency test and find out!
The AMD QuadFX FX-70 test system was found to have an inter-core bandwidth of 4,510MB/sec and a latency of 104ns.
The Intel V8 test system on the other hand had a much higher inter-core bandwidth throughput of 19,010MB/sec and a lower latency of 59ns. According to SiSoftware Sandra the processor cores are more efficient on the Intel platform.
