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 only the CPU test suite.
With PCMark04, the AMD Athlon64 4000+ showed better performance than the 3800+, as expected, but the FX-55 dominates over both the 4000+ and the 3800+.
The test results, more analytically:
|| AMD 4000+
|File Compression (MB/sec)
|File Encryption (MB/sec)
|File Uncompression (MB/sec)
|Image Processing (MPixels/sec)
|Grammar Check (KB/sec)
|File Decryption (MB/sec)
|Audio Conversion (KB/sec)
|WMV Video Compression (FPS)
|DivX Video Compression (FPS)
In all these tests, the 4000+ leads the 3800+, but only by a small amount.
