March 25, 201115 yr I'm thinking of getting a Dell Zino 410 with the 5450 GPU. I've been doing some reading (anandtech, see quote below) and saw that there might be a problem with 1080P 60fps. My current htpc uses an i3-530cpu on a gigabyte h55m-usb3 mb. My blu rays are stored on my server in a folder structure which I access via TMT 3 to play. My tv only handles 1920x1080P 60fps. Movies play flawlessly. For the life of me I can't figure out if the zino 410 would work just as well. I'm looking at the one with the AMD Turion™ II X2 P360 (2.3GHz/1MB cache) and 4GB of ram. Anyone have any ideas? Here is where the downer comes in. While going through our media streamer test suite, we found that many 1080p60 H264 clips wouldn't play properly. We had protracted communication with both Dell and AMD, and it was one of the main sources of delay with respect to the publishing of this review. We waited quite a bit to see whether driver updates would fix the issue, but release after release went by without any improvement in the situation. After Catalyst 11.1, we gave up. The short story is that the HD 5400 series (Cedar based) is qualified for content up to 1080p 24fps only. At that format all the video quality features are available with the exception of mosquito noise reduction and deblocking. Anything beyond that format is not qualified for the Mobility 5450. Even though some instances of that format (1080p30 or 1080p60 H264) may play back, it's not guaranteed that it will be smooth. All in all, the Mobility 5450 falls short in its support for certain encodes when compared with its midrange and high end cousins, as well as the nVidia 4xx GPUs and Intel HD Graphics.
