XMPEG is a Video File
Conversion Utility, that utilizes compression and
decompression techniques to target various video/audio file
formats with an installed system CODEC. We took our
in-house 19MB MPEG video clip and converted it using the
latest DIVX 5.05 CODEC.
XMPEG And PCMark 2002
Real world video
conversion and synthetic CPU testing
In frames per second - Higher scores are better
This is another
test that stresses overall system bandwidth and seems to be
well optimized for the Pentium 4. We should note that
with this new 5.05 version of the DIVX CODEC, Athlon XP
3200+ performance dropped by almost 25%. With the
older 5.02 version of the DIVX CODEC, the Athlon scores a
57.1, which is still far below the Pentium 4's watermark but
better than what we're showing here none-the-less.
PCMark 2002 is a synthetic suite of benchmarks for various
aspects of system performance. We ran the CPU
performance module, which runs through a series of both
integer and floating point workloads, including JPEG
decompression, Zlib compression & decompression, text
search, Audio Conversion and 3D Vector Calculation.
According to this test, the new 3.2GHz P4 is 18.5% faster
than an Athlon XP 3200+ and about 7% faster than a 3GHz P4.
We'll cover one
more series of synthetic tests and then get back to
real-world application and gaming benchmarks.
