Even blue-ray?

Anyway sifus, is it true that even just watching movie, but a ATI discrete GPU is clocking higher than Intel HD3000 and causing higher heat? Or it doesn't matter unless is heavy loading such as for gaming, only it will heat up?

ooo thanks guuys, keep wondering about Blu-ray thing since after years it will be very normal standard to consumer.. scared HD3000 will have jerky when watching blu-ray.. will it?

Means only when gaming will result higher heat while normal lite games and movie it will not cause heating problem or?

Have any idea with HD 6470? according to http://www.notebookcheck.net/AMD-Radeon-HD...0M.43075.0.html
Core Speed * 700 / 750 MHz
Shader Speed * 700 / 750 MHz
Memory Speed * 800 MHz

http://www.notebookcheck.net/Intel-HD-Grap...00.37948.0.html (HD3000)
While HD 3000's Mainstream and high-end Dual und Quad-Core Core ix-2xx0 (base 650MHz, Turbo 1100-1200MHz)
Core Speed * 350-1350 MHz
Shader Speed * 350-1350 MHz

If to compare, somehow normal rate HD3000 < HD6470 clocking by 50-100 but when it runs with turbo will be super fast clock which will lead higher heat than HD 6470?
