I have a question on the speed of Blender on different CPUs : I just built a new PC with a Pentium 4 3.4GHz and it seems that it is not a lot faster than my previous PC built with an Athlon XP 2000+.
So I made a test, with the same Blender version, the same scene, the same renderer settings, and here are the results :
Athlon XP 2000+, CPU used at 100%, 1 minute 21 seconds for rendering the scene.
Intel P4 3.4 GHz, CPUs used at an average of 50%, 1 minute 16 seconds.
During the test, I realized that the two (virtual) CPUs of the P4 were running at only 50% on average :o .
Does somebody know why Blender does not use 100% of the CPUs on Intel P4?
Is this something that can be corrected with a Blender built dedicated for Intel P4 ?
Thanks in advance for your answers.
