如果是 h264(X264) 之類的 FULL HD,要軟解的話,即使四核也很吃力..
真的要順,還是交給顯卡去處理吧,新的顯卡都支援 h264 加速,價錢也不高
真的要軟解,就準備一顆 i7 ,應該能順利播放,不過組 i7 主機的錢,夠買好幾張顯卡了
Not quite. I have two video cards on one motherboard ( not Cross Fire mode. I use it for 4 monitors out ).
One is HD 4870 & the other is HD 2400 Pro.
Here is the tests I just did, under Vista media Center.
HD4870 :
Q6600 ( 四核CPU ) + HD 4870 + CoreAvc 1.85 ( 軟解 )
720P MKV movie = CPU ( 10 ~15 % ) + GPU ( 5% ) Usuage .
1080P MKV movie = CPU ( 10 ~15 % ) + GPU ( 45% ) Usuage .
HD2400 Pro :
Q6600 ( 四核CPU ) + HD 2400 Pro + CoreAvc 1.85 ( 軟解 )
720P MKV movie = CPU ( 10 ~15 % ) + GPU ( 50% ) Usuage .
1080P MKV movie = CPU ( 15~ 25 % ) + GPU ( 80% ) Usuage .
1080P Movie runs smoothly on both video cards with quadcore.
So, 1080P 軟解 to 四核CPU is a piece of cake. However, it's a bit heavy to HD 2400 Pro.
If you want to 軟解 1080P, you need to udgrade your motherboard + CPU ( core 2 quad ).
If you have cash to burn, go for it. ( around 250 ~ 300 USD )
Who cares about 硬解 if you spend only 10 ~ 20 % CPU usuage to make the image looks better
on 軟解. Not even mention you can decode all the HD movies without any issue.
However, if you are under budget , buy a HD 4350 to 硬解 1080P movies. ( 30 ~ 40 USD )
If you want to play game as well, get a HD 4670 for 硬解 + game . ( 80 ~ 100 USD )
