However, there are other benchmark software alternatives to Sandra. One good alternative is PassMark Performance Test. PassMark provides 28 standard system benchmarks, and like Sandra hardware can then be compared with other alternatives. This multi-platform benchmarking software can therefore be a good alternative to Sandra, but it should be noted that it is not freeware. However, you can still download a 30-day trial of the full software package to benchmark your current hardware.
If you are more interested in benchmarking your hardware in relation to PC games, then you might consider some of Futuremark's benchmarking software such as 3DMark Vantage. This is industry standard benchmark software for DirectX 10 PC gaming, and it has a basic freeware edition as well as more advanced premium editions which are hundreds of dollars. Software such as SuperPi can also time how long it takes for a PC to calculate Pi to a certain number of digits, a good processor benchmark, although aside from this provides few other options for benchmarking. However, the software is available for download.
As such, you can benchmark your Windows 7 PC with the Windows 7 index as well as software titles such as Sandra, 3DMark Vantage, PassMark, and SuperPi. Install this software to begin benchmarking your desktop PC, and if hardware upgrades are required consider some of the alternatives listed at the SiSoftware website.
