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. 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, PCIe, ODBC Connections, USB2, 1394/Firewire, etc.
Sisoft Sandra offers two tests, unbuffered and buffered. We sum them, divide them in half and present you with the results.
At Sisoft SandraXII, the results were a mixed bag. At DDR3-1333 and DDR3-1800, the OCZ DDR3-1600 had the highest performance, while at DDR3-1600, the Crucial DDR3-1600 performed better.
Before this test packet was created there was no proper software for measuring vital system parameters such as CPU/Chipset/RAM providing steady and reliable (reproducible) test results and allowing for changing test parameters in a wide range.
Vital low-level system characteristics include latency and real RAM bandwidth, average/minimal latency of different cache levels and its associativity, real L1-L2 cache bandwidth and TLB levels specs. Besides, these aspects are usually not paid sufficient attention in product technical documentation (CPU or chipset). Such test suite, which combines a good deal of subsets aimed at measuring objective system characteristics, is a must have for estimating crucial objective platform parameters.
RightMark offers a variety of test results, including both read/write performance from synthetic and performance tests:
The OCZ DDR3-1600 had the highest scores at the Synthetic Real Read tests. Again the OCZ DDR3-1600 showed very good performance at the Real Write and Real Performance tests:
