ATI Radeon 2400 and ATI Radeon 2600 Now Shipping to Board Customers
AMD is now shipping ATI Radeon HD 2400 and ATI Radeon HD 2600 graphics processors in volume to its board customers. Graphics cards based on these processors are expected to be available at online retailers within a few weeks from board customers including Asus, Club 3D, Diamond Multimedia, GeCube, Gigabyte, HIS, MSI, Palit, PowerColor, Sapphire and VisionTek.
Radeon HD 2400
Both graphics processors feature AMD’s UVD (Unified Video Decoder) technology. UVD is a hardware feature that offloads video decoding from the CPU to the GPU to lower system power consumption. This is particularly important for media center PCs (because lower power consumption means quieter cooling solutions) and notebooks (where power consumption dictates battery life). UVD is designed to be used in a range of video applications, for example, watching Blu-ray, HD DVD or standard definition movies.
Radeon HD 2600
AMD also wishes to clarify any confusion that may exist regarding the presence of the Unified Video Decoder (UVD) in its ATI Radeon HD 2000 series graphics processors. UVD is present in the ATI Mobility Radeon HD 2300, the ATI Radeon HD 2400, and the ATI Radeon HD 2600 series products, but is not present in the ATI Radeon HD 2900 series products as it is not needed due to the usage model of this high-end product.
Radeon HD 2600 XT
The ATI Radeon HD 2400 and ATI Radeon HD 2600 cards are designed for use in entry-level and mainstream systems, in which the UVD technology is beneficial for watching high definition movies. In contrast, the ATI Radeon HD 2900 XT is a high-end desktop card for gaming enthusiasts, and designed to be used in high-performance PCs. According to the press release, in these environments, the CPU can perform software decoding of HD video without being overburdened and UVD technology is not required.

1 The ATI Mobility Radeon HD 2300 has a fundamentally different architecture to which the term “stream processor” is not equivalently applicable.
2 The ATI Radeon HD 2400, ATI Radeon HD 2600, and ATI Radeon HD 2900 have full support for HDMI and HDCP (including HDCP keys) built into the processor itself; availability in consumer products is determined by the specific solution provider (board partner, PC manufacturer or notebook vendor). The ATI Mobility Radeon HD 2300 can support HDCP and HDMI with additional components. Purchasers of ATI Mobility Radeon HD 2300 products manufactured by third parties should inquire whether the manufacturer has enabled HDMI and/or HDCP in such product.
