Graphics cards with ATI Radeon HD 5xxx series GPUs keep on attacking their opponents on each front. By today, the dual-processor Radeon HD 5970 has affirmed itself as a premium-class solution, the high-end sector is occupied by the Radeon HD 5870 and 5850 whereas the Radeon HD 5770 and HD 5750 are getting more and more popular as mainstream products. A Radeon HD 5830 with a highly attractive price/performance ratio is scheduled for release, too. It is only in the low-end sector that there have been no graphics cards with the new GPU architecture and DirectX 11 support. To make up for this deficiency, AMD has rolled up its Radeon HD 5670 graphics card which is based on the 40-nm Redwood GPU, the junior model in the Evergreen family.
