ATI's RV550 to merge GPU and video processor

ATI looks to have a new mainstream card up its sleeve, and this one should cater to home theater PC users who intend to run Windows Vista. ATI slides nabbed by HKEPC reveal an upcoming RV550 part that incorporates both a Radeon X1000-class graphics processor and a Xilleon-based dedicated video processor inside a single chip. The Xilleon is itself a single-chip solution for devices like set top boxes and digital TVs; it includes a MIPS processor, high-definition video decoder, audio decoder, I/O, and a host of other features.

According to the slides, the RV550's integrated video processor will allow it to handle "worst case" Blu-ray and HD DVD playback when paired with a mainstream CPU. The RV550's graphics processor may not be too shabby for a mainstream part, either: it'll be clocked at 600MHz with four pixel shader processors, 800MHz GDDR2 memory, and a 128-bit memory bus. In addition to the merged video decoding and graphics processing capabilities, HKEPC says ATI is encouraging its partners to include both High-bandwidth Digital Content Protection and HDMI output support in their RV550-based products. These products are due to enter production in December, the slides say.
