Power Consumption

Thanks to extensive power/clock gating, idle power consumption of Trinity is easily on par with the best Intel has to offer with Ivy Bridge. It's entirely possible that we'd see lower numbers with more power efficient motherboards/PSUs, but at least here it looks like AMD's idle power concerns are a thing of the past. Load power is another issue altogether. Trinity may be more efficient than Llano at delivering performance, but it's still built on the same 32nm process node. Load power consumption doesn't go up significantly compared to Llano, but it doesn't go down either. It's going to take new process nodes and design techniques to really drive active power down in future APUs.

    Anand - always 3 months late to the party. Reply

    What are you talking about? AMD is just now lifting the NDA on the Trinity A10-5800K & A8-5600K desktop CPUs (and even then, sites can only talk about GPU performance).

    If any site had reviewed a Trinity APU several months ago, it was the mobile version (A10-4600M). Anandtech even reviewed it here:

    I believe he was referring to this:

    None of those numbers compare Trinity to the competition. They're mostly worthless. Reply

    Engadget has word the A10 is aiming at i3 prices and i5 performance on the CPU side. We've already seen A8 and A10 cream the i3 and i5 in GPU. I'm excited. I haven't built an AMD system in years, and the A8 65w might be a perfect HTPC CPU. Reply

    Tom's has benchmarks against a Core i3-2100 if you'd like to see how it stacks up. Reply

    i can't find any of tom's benchmarks showing a comparison of THESE chips against any Intel chips. They all compare the A10 and A8 to eachother. Reply

    If its anything like the Lano, the top end 65w's will basically only be released to the OEM's. Which to me are the only ones worth having. Reply

    That was because of AMD's lousy yields and contracts which prioritized access of the supply to the likes of HP and Acer over the retail channel.

    OEMs still have first dibs, but yield issues are apparently better now. I have high hopes for the 65W parts (which includes actually being able to buy them on Newegg!) The A10-5700 could be the best of all worlds.

    Agree! I want to A10-5700 probably. No brainer. Reply
