During this fall, AMD has been releasing their new Radeon HD 5000 Series cards. Currently, the smallest model is the Radeon HD 5750, which uses the same Juniper GPU as the HD 5770, but with lesser shaders, and reduced clock speeds. Unlike with the big Radeon HD 5870 and HD 5850 models, for the Radeon HD 5700 series, add-in-board partners are allowed to make changes to the design right from the start to ensure optimal pricing, availability or other unique selling points they may have. Sapphire's HD 5750 uses an AMD reference PCB, but with a typical Sapphire blue PCB. As cooler, Sapphire uses an in-house design that has been used on other HD 4xxx Series cards before.
