 Preliminary Testing with SiSoft SANDRA XII SP2a
 Synthetic Benchmarks

We began our testing with SiSoftware's SANDRA XII, the System ANalyzer, Diagnostic and Reporting Assistant. We ran three of the built-in subsystem tests that partially comprise the SANDRA XII suite with the XPS 730x H2C (CPU Arithmetic, Memory Bandwidth and Memory Latency).  All of the scores reported below were taken with the processor running at its out-of-box clock speed of 3.73GHz, with 6GB of tri-channel DDR3 RAM.

Processor Arithmetic

Memory Bandwidth

Memory Latency

SiSoft SANDRA's various benchmark modules reported scores right in-line with our expectations.  The XPS 730x H2C's overclocked Core i7 processor and tri-channel DDR3 put it ahead of all reference systems in all three tests. The lead the XPS 730x has in the processor arithmetic and memory bandwidth tests are particularly stunning. The advantage of the new Core i7 processors and tri-channel memory are plain to see.
