SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software.


Sandra is a (girl) name of Greek origin that means "defender", "helper of mankind". We think that's quite fitting.


It works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what's really going on. Giving the user the ability to draw comparisons at both a high and low-level. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCI-X, PCIe (PCI Express), database, USB, USB2, 1394/Firewire, etc.




SiSoft Sandra is the one test that companies have said show you the best results when it comes to testing the new Quad Channel platform and you can see from the results above that it can't be denied. With our system at stock you can see that performance on the Quad Channel platform skyrockets when compared that of the Dual Channel one.


There's a few interesting things here, though. The first is the Dual Channel performance on both platforms. You can see that while both RAM kits are running at the same speed, the Z68 Dual Channel performance is actually slightly stronger than the X79 Dual Channel performance. There's not much of a difference, but it's consistent in both stock and overclocked tests.


Comparing stock and overclocked tests also sees both dual channel setups yield almost no performance increase, while the X79 Quad Channel setup does see a boost in performance. Saying that, we do see that comparing the stock and overclocked numbers, the overclocked numbers see improved latency.


Latency brings us onto our final point, though. You can see that Latency on the X79 platform sits behind the Z68 one across the board.
