AMD is tipping its hand early at the CEATEC technology show by showing a pre-production version of a Mobility Radeon HD 4000 chipset. Although AMD has yet to publicly discuss the hardware, the company's booth at the Japanese expo contains a clearly identified test bed with the notebook-oriented chipset demonstrating its full hardware Blu-ray video decoding.
The demo unit has a large expansion card and a desktop-class cooler but is believed to be using these only for simplicity's sake in the development phase. Most production notebooks often use custom-designed cooling and embedded graphics that are impractical outside of complete systems.
AMD is believed to be launching the first Mobility Radeon HD 4000 chipsets later this year with basic, mid-range and high-end versions that mirror their equivalents in the current 3000 series.
