Our Test Systems and SANDRA

 

How We Configured Our Test Systems: When configuring our test systems for this article, we first entered their respective system BIOSes and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS and set memory timings for either DDR2-1066 (AMD) with 5,5,5,15 timings or DDR3-1333 with 7,7,7,20 timings (Intel). The hard drives were then formatted, and Windows Vista Ultimate was installed. When the Windows installation was complete, we updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, defragged the hard drives, and ran all of the tests.

 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 six of the built-in subsystem tests that partially comprise the SANDRA XII suite with AMD's new Phenom X2 8750 processor (CPU Arithmetic, Multimedia, Multi-Core Efficiency, Memory Bandwidth, Cache and Memory Bandwidth and Memory Latency).  All of the scores reported below were taken with the processors running at its default clock speed of 2.4GHz, with 2GB of DDR2-1066 RAM running in 128-bit unganged mode.



Processor Arithmetic


Multimedia


Multi-Core Efficiency




Memory Bandwidth




Cache and Memory




Memory Latency



SiSoft SANDRA's various benchmark modules reported scores right in-line with logical expectations.  The tri-core chip was more powerful than AMD's dual-core offerings, but note quite as powerful as a quad-core.  The multi-core efficiency and various memory related tests all reported similar scores to quad-core Phenom X4 processors, which is to be expected considering they are the essentially identical.
