AMD released the new Radeon HD 5670 earlier. The card was the first card of the AMD Evergreen family with MSRP under $100. On February 6th we should see the rest of the budget segment arrive when the Radeon HD 5500/5400 arrives. Cedar is the name of the stripped down graphics circuit where focus is on features before performance.
The ATI Radeon HD 5500 series will consumes less than 50W at load and sport low-profile design with a slim active cooler.
Even if ATI Radeon HD 5450 will also use a low-profile design, but it will get around with a passive cooler, I.e. no fan. With regular I/O bracket the card can control three monitors through Eyefinity, but the perhaps most appealing is bitstreaming of Dolby TrueHD and DTS-HD Master Audio, and the integrated video processor for HTPC users.
The 3D performance will be limited, but they are still some of the most interesting for many users.
