10-100% for onboard software raid 0 (depending on the cpu and number of drives in the array)
add it all up using the lowest numbers and the total comes to 27% of the cpu's time is being spent doing other things besides work. Dedicated onboard processors also offer better performance than there software based motherboard cousins.
That is not including USB (unlike 1394, usb has cpu overhead) and onboard graphics you maybe running.
I am, at this time, ONLY talking about NIC.
Yes, sound is a given... it is horrible quality, and it has high CPU utilization. But its there if you should ever need it.
Ok... how do you have Onboard Software RAID 0. Onboard and Software cannot go together. You have one or the other. Software RAID is like going through windows Disk Management and spanning the drives together into one large one. In HW you have a dedicated chip... be it the Southbridge or a 3rd party chip such as Silicon Image.
Dedicated onboard processors also offer better performance than there software based motherboard cousins.
Yes but the average home user will not take advantage of it. Hell even most of the people here wont take advantage of the added throughput. It BARELY uses CPU as it is. If you are concerned about a MAX of 5% CPU usage then close some background apps.
Onboard graphics does not go through the CPU! It has an onboard GPU, and a direct link to the memory. It uses up no more processing cycles than a 3rd party Video Card would, (setting aside HW and SW optimizations and features).
USB... again MINIMAL difference. Do this, unplug all USB devices and turn off all USB ports. Do you notice any difference whatsoever?
