YouTube videos CPU or GPU?

Solution
On a pentium 4 480P youtube videos sometimes stutter.
Then I check the CPU usage it was quite high.
The CPU is more important for HTML5 videos.
Now when I test youtube with flash player the Pentium 4 can play 720P with youtube videos with some stutter every now and then.(More smooth video playback than HTML 5 with flash player but because of the pentium 4 single with no hyper threading the CPU usage sometimes spike and cause stutter to the video playback every 10-15 second)
So in conclusion the CPU and GPU is also important for playing flash youtube videos.
If you have a dual core system paired with dedicated GPU it will play the video smoothly.
Do note that using flash player will result in lower CPU usage as the dedicated video card...

Do note that using flash player will result in lower CPU usage as the dedicated video card is taking some of the load from the CPU.
