hi, i watched a 1080p movie today, and found out that cpu usage is 80% all the time . and gpu temp increases only 3C during movie.
my spec is
e6300 wolfdale (2.8 Ghz, not the old one)
3 GB ddr2 800
evga GTS 250 512MB
p35 ds3l mobo
i couldnt use riva tuner for this card, it doesnt show gpu load percentage, so i set the fan at 35% and watched the temperature to approximate the load during the movie. i also locked the clocks at normal 756mhz, 1836mhz, 1100mhz. core, shader, and memory respectavly by evga precision. at idle with 35%, temp is 63C. and during movie, it is 66C. again, with same fan speed 35%. i know this is weird way to look at gpu load. but i think i can make a guess by these values.
when this gpu is fully loaded with games, like crysis, temp will go up to 74C with 60% locked fan, or to compare with low fan speed ( i risked it just to see the temp..) 98C with 40% fan rotation. i turned off the game right when i saw 98C because it was increasing about 1C in 2 secs
i heard from different places on internet, that a decent gpu will take work from cpu when watching hd movies. is this normal cpu usage during 1080p movie?
So, when watching 1080p video, the GPU will do the job and not CPU, is it right Mod?
I'm sorry that i'm wrong when i giving info to the OP...
If your video player doesn't know how to access, or it simply doesn't access the gpu, all the work gets passed onto the cpu. In your case though, it seems that a lot of work is still passed onto the cpu.
I've been using the aforementioned version of MPC with the 257.15 beta drivers and it does seem to do the offloading bit quite well considering that I'm using a lowly 9500GT, the CPU fan does a lot less work now.
is it harder for cpu to calculate hd movies than gpus?
it seems like my gpu does this work like nothing when cpu gets rapes when cpu does it by itself
The GPU does this better because it is what the gpu was designed to do, process and load pixels onto your screen.
The cpu is designed to do a little bit of everything, so it excels in nothing. The gpu was made to push pixels, which incidentally is also about number crunching. That's why gpu's are good for parallel compute applications.
