Performance: Streaming Data Processing
Most applications working with streaming data are known for being faster in systems with Pentium 4 processors. This is exactly the case when NetBurst architecture can show its best. Therefore, the result obtained in WinRAR 3.2 shouldn’t seem surprising to you. The fastest Pentium 4 models appear much faster in data compression than the top Athlon XP CPUs.
We observed a similar situation during mp3-files encoding with LAME 3.93 codec. By the way, this codec supports multi-threading that is why Hyper-Threading technology helped Pentium 4 processors to win here. As a result, Pentium 4 3.2GHz appeared about 20% faster than Athlon XP 3200+.
Here we also included the results of AVI-movie encoding into MPEG-2 format with the help of one of the best Canopus Procoder 1.5 coder. Strange a sit might seem, but Athlon XP appeared a little faster here. However, Athlon XP owes its victory to faster floating-point unit. As we see, SSE2 instructions of Pentium 4 processors can hardly be considered an alternative here, even though the performance gap between the two rivalry families is not that big at all.
Video encoding into MPEG-4 format is another example of Hyper-Threading and 800MHz bus efficiency in certain tasks. Pentium 4 3.2GHz proved about 20% faster than Athlon XP 3200+ here.
When we encode video data with the help of Windows Media Encoder9, the situation is very similar. This application is optimized for SSE2 instructions and suits excellently for NetBurst architecture. That is why it is not at all surprising that Intel processors are again at the top of the diagram.
