Not yet announced by AMD, the Radeon HD 8000 family of graphics cards has already started to creep up courtesy of several e-tail stores who jumped the gun and put up for pre-order an ultrabook (the ASUS VivoBook U38DT-R3001H) equipped with a Radeon HD 8550M. Unfortunately the listings are short on details and only mention that the Radeon HD 8550M (which hopefully isn't a rebranded 7 series card) has 1 GB of memory.
In addition to the HD 8550M, ASUS' 1.6 kg ultrabook packs a 13.3-inch (1366 x 768) LED-backlit display, a 1.6 GHz A8-4555M processor, 4 GB of RAM, a 500 GB hard drive, 802.11 b/g/n WiFi, Bluetooth 4.0, B&O ICEPower audio, an SD card reader, three USB 3.0 ports, an HDMI output, and a 6-cell battery providing up to 5 hours of operation. The VivoBook U38DT-R3001H runs Windows 8 and is priced at €799
