Today Samsung Electronics unveiled the Series 5 Ultra, a 'high-performance' ultrabook which will debut in South Korea at the end of this month and will probably (hopefully) reach other markets in early 2012. This new mobile solution makes use of an aluminum chassis, comes in 13.3-inch and 14-inch versions (the 13-inch model is 14.9 mm thick, the 14-inch is 20.9 mm), and features a yet unnamed Intel processor, up to 8GB of RAM, a 500GB/1TB hard drive or a 128GB solid state drive, and 8GB of ExpressCache memory which ensures lower boot and access times (Samsung claims that its machine can come out of sleep mode in under 2 seconds). The 14-inch unit boasts a Radeon HD 7550M discrete graphics card and an optical drive while the 13.3-inch model has to settle for an integrated Intel GPU and no ODD. The Series 5 Ultra also has WiFi, a webcam, two USB 3.0 ports, and both D-Sub and HDMI outputs. Pricing in Korea is said to range from about US $1,121 to US $1,339.
