PCMark04 is an application-based benchmark and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark04 to be a smaller installation as well as to report very accurate results. As far as possible, PCMark04 uses public domain applications whose source code can be freely examined by any user.
PCMark04 includes 4 categorized suites for benchmarking your computer. These include CPU, Graphics, Memory and a Hard Disk Drive benchmark. In our case, we selected to run only the Memory test suite.
According to PCMark's total score, Apacer was faster at 650MHz and at 690MHz while Transcend had slightly better performance only at 533MHz.
If you take a look at the following table, you'll notice that in quite a few cases, Transcend reported higher transfer rates.
