AMD claims the Radeon 4500 series GPU units will deliver 3.7 times the performance of their previous GPUs; and will even consume less power, meaning a longer battery life. In order to keep track of power consumption the 4500 series GPU will take advantage of integrated ATI Powerplay technology. The built-in Microsoft DirectX 10 support means the Radeon 4500 series devices will be fully compatible with Windows Vista, and will also support the Aero graphics interface. AMD quotes that users of the Mobility Radeon 4570 will be able to experience full HD quality content, including HD video editing, Blu-ray media, Picture-in-Picture (PIP) media, High definition photos, and users wil also be able play the most popular and demanding 3D games to date. The Radeon 4550 and 4570 GPU devices also include support for 7.1 channel pass through audio to the integrated HDMI port. At this time there is no further information about the onboard memory capacity, memory clock speed or core clock speeds of the ATI Radeon 4570 device but it will likely feature similar specifications of the closely related ATI Mobility Radeon 4550 card.
