[citation][nom]hellwig[/nom]While the idea of an all-Intel world frightens me, I don't see why portable computers
need discrete graphics cards for HD content playback. So what if your laptop takes a lot of CPU power to decode blue-ray, modern CPUs are a lot more energy efficient than any worthwhile GPU. If it runs without stuttering, who cares what component is doing the decoding.I don't see gaming as a top priority for most notebook manufacturers.[/citation]
Actually thats incorrect. A decent GPU for HD playback, lets say ATI's integrated 3200 series, can playback 1080p video using either a low end cpu or a high end cpu that clocks down (cool n' quiet). I believe there was a Tom's Hardware article about the lowest power hungry system was a 780g motherboards with a sempron Athlon X2 BE-2350. Aww, fuck it, here the link: http://www.tomshardware.com/reviews/amd-780g-chipset,1785-15.html A quote form the article: "Since the on-board GPU handles all of the decoding operations for the H.264 and VC-1 codecs, the power consumption of the brawnier CPUs increases only marginally."
And noone ever said you need discrete graphics. AMDs integrated graphics are just fine, but Intel has been lacking in that department for quite sometime.
The fact of the matter is when it comes to Blu-ray playback going through the GPU is much more energy efficient when using the right GPU than using a CPU. It also allows you to multi-task .
