It was the same story when we used DivX 7, iTunes 8.1 and CyberLink PowerProducer 5 as they clearly are not able to make effective use of multiple cores.
DivX 7 Video Encode
In iTunes, we converted 458 MP3 files - totalling 2GB - to AAC format, and in DivX we worked with six AVI movies that also totalled 2GB. In Power Producer we recoded a single 350MB AVI file to DVD format. We can illustrate the lack of efficient threading as a single Xeon that is converting files in DivX 7 uses all eight cores at about 50 per cent load. Installing a second Xeon drops the load to 30 per cent on each core.
Power Producer AVI-to-DVD Encode
how about php/webserver tasks and database tasks vs a similar spec xeon 5400.
@ "Not desktop"
Odd. The MacPro, containing a pair of these mofos, looks a lot like a desktop to me.
All we need to do is get shot of that 'orrible OSX...
Is the X5550 really £958 and not $958? :)
Steve because he shipped them 1st.
Impressive test results
So, you run a bunch of tests that
1) Can't actually test the performance of the kit
2) Is not actually relevant to the intended uses of the kit
3) Despite points 1 and 2, declare the performance as breathtaking.
If you MUST do video compression testing on multi-core CPU's, then at least endeavour to use software that, you know, can utilise multiple cores.
DVDRIP on linux springs to mind.
