TPU reports details about the ASUS VivoBook U38DT ultrabook popped up on the web. Several e-tailers started listing this ultrabook, with one of the most interesting details being its Radeon HD 8550M GPU. There aren't any details about the GPU though, other than that it has 1GB memory. It could be that it's just another rebrand though.
