Test Systems and SiSoft SANDRA

Test System Configuration Notes: 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 DDR3-1333 with 8,8,8,24 timings. The hard drives were then formatted, and Windows 7 Ultimate x64 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, performed a disk clean-up, defragged the hard drives, and ran all of the tests.

Preliminary Testing with SiSoft SANDRA 2009 SP4

Synthetic Benchmarks

We began our testing with SiSoftware's SANDRA 2009 SP4, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2009 SP4 suite with Intel's new Core i5 and i7 800 series processors (CPU Arithmetic, Multimedia, Memory Bandwidth, and Cache and Memory). All of the scores reported below were taken with the processors running at its default clock speeds of 2.93GHz and 2.66GHz with 4GB of DDR3-1333 RAM running in dual-channel mode on the Gigabyte P55-UD6 motherboard.

Processor Arithmetic Core i5 750	Multimedia Core *i5 750*	Memory Bandwidth Core *i5 750*	Cache and Memory Core *i5 750*
Processor Arithmetic Core i7 870	Multimedia Core i7 *870*	Memory Bandwidth Core i7 *870*	Cache and Memory Core i7 *870*

The Core i7 870 puts up much stronger scores than the i5 750 in the SiSoft SANDRA CPU Arithmetic and Multimedia benchmarks, not only because the chip is clocked higher by default, but because it supports HyperThreading as well, which allows the chip to process 8 threads simultaneously, as opposed to 4 on the Core i5. Despite the fact that both processors were equipped with the same memory, the Core i7 860 also offered more memory bandwidth 16.8GB/s (Core i5) vs. 17.3GB/s (Core i7).

In light of competing platforms in SANDRA's database, Intel's new mainstream chips perform very well, besting the previous generation and anything from AMD.
