    Thanks for the link! That pretty much kicks Intel ATOM 330 out, but not ION. I saw that MB still use IGP 6310 - UVD is a must if target is ION. And thats full UVD3.

    Thats nice that Bridgeman does, but I didn't like his reactions and that of Xorg dev team (again, thats personal reception) - it made me think its gonna be complete in 20 years and even then at the same time result won't be usable with the modern hardware. Either polished outdated technology as opensource, or proprietary and modern. Nvidia already has modern and proprietary (but you know). This leaves AMD be choice for very old systems.

    I use quadcore with 4 gigs of ddr3-1600 with linux on home desktop, now.

    But then you get a disadvantage of power mgmnt on current selling K10. Intel would already be better with core i+ in long run.If bulldozer comes this may change(I hope it will).
    fusion allready chance this exampel:

    bobcat fusion really beats all other solutions in power saving.

    As for gpu, I dont want to touch catalyst, not even for testing. It was plain horror. Maybe I will boot my system on LiveCD to test it soon on vaapi, when I sell amd and get nvidia card(don get me wrong I strong dislike nvidia, but there is no choice from amd). I know that nvidia vdpau works even on ion, and nvidia has been ignorant to some hw support cases, but amd current policy is not acceptable for me now. I dont want windows and I want working hardware(long window, 3d features, stable, hw video decode logic) or the real strong line behind rising opensource that is internally better. Nothing here from AMD, but I don't want to hijack the thread with my situation.
    the fusions are a choice if you wana save powerconsuming...
    and no the fusion is not the same like old K10 cpus in power saving options.
    the fusion do have 1-3 watt in idle and 18 watt REAL-max-TDP (not the intel funny TDP).

    and amd (bridgman) work right now about openup the UVD unit for the radeon driver.

    and the Google chrom browser accelerate WebM in Shaders and you also can accelerat h264 in shaders.

    maybe bobcat is to slow but Llano is much faster thats for sure.

    last night i test flash h264 video test video on youtube on an radeon driver based on kubuntu 11.04 and the video runs fine on 1080p

    sure its an passiv cooled hd5450+passiv cooled [email protected],6ghz (downclocked)

    Uh sorry, I made a mistake above. Thats not 111W, thats 106W.The rest is correct.

    My Atom 330 system uses ~42 - 43 watts with 1 7200RPM drive under a full CPU load. It also takes 8 hours to do 1 of 2 passes on a 1.5 hr SD video encode to Theora.

    Atom 330
    Normal 330 dualcore (4HT) (CPU+MB) -> Idle: 30w, Load: 41w

    Atom 220 on nvidia ion
    Normal 220+ion single core(2HT) (CPU+GPU+MB) -> Idle: 16w, Load: 26w

    Lets take a version you watch one movie daily - thats 2 hrs/1 day.
    365*2= 730hrs/year
    Europe best energy cost: 10?/Month + 0,20?*kW/hr
    For a year thats: 120? + 0,20?*kW/hrs

    For undervolted AMD Phenom II always idling at watching movies vs always full load ion:
    0,20?*0,111kW*730= 16?/year
    0,20?*0,026kW*730= 3,7? year

    Realistically I seriously doubt phenom will idle at movie play. Or igp/discrete gfx card it uses will idle, so its absolutely best case.

    ion system cost is around 100?. Do you need it - I think yes if you use around 4hrs a day for 3 years.

    If you want, you can suck it up and try to wait for bulldozer with their powergated cores and improved TURBOcore
