A little earlier today, we showed you pictures of AMD's first Radeon HD 7900 series single-GPU PCB that makes use of digital-PWM power delivery. Some of the first batches of Radeon HD 7900 graphics cards will stick to that PCB and board design, as it's backed by AMD's engineering. Even as the SKU's launch is less than 24 hours away, there are pictures of AMD's cost-effective Radeon HD 7900 PCB surfacing on Asian media sites. Once ready, AMD add-in board partners can opt for this cost-effective PCB if they want to fine-tune their prices. It looks like AMD is ready well ahead to face competition from NVIDIA, with its GeForce Kepler 104 (GK104) GPU.

The cost-effective PCB, without any components laid, is pictured below. The first picture shows its obverse side, the second, its reverse side. The PCB is completely up to speed with everything Tahiti GPU will need. It has provision for two 8-pin PCIe power inputs, an 8+2 phase cost-effective analog VRM, probably driven by a cost-effective CHIL controller, and a different display output connector loadout. It has provision for two DVI, and one each of HDMI and full-size DisplayPort. Partners can still use a single DVI connector, and keep their cards single-slot capable. Provisions for 12 GDDR5 chips are right where they should be. There is nothing eventful in the reverse side, just traces for all the supportive components.
