Looking good: single power PCB design
Two days after reports surfaced about NVIDIA readying the GeForce GTS 450 mainstream graphics SKU for a late August launch, PCInLife got a hold of the PCB's x-ray drawings, which reveals quite a bit about the GF106 GPU the GTS 450 is based on. The PCB reveals a square GPU that is bordered on three sides with six memory chips, is powered by a 3+1 phase VRM, draws power from a 6-pin PCI-E power input, supports 2-way SLI, and has display outputs including two DVI and a mini-HDMI.
The presence of six memory chips particularly intrigues, as it could indicate a 192-bit wide memory interface. Perhaps two of those slots are empty, if GTS 450 does end up with a 128-bit memory interface, and enabled on a higher SKU, or that GTS 450 itself has a 192-bit memory interface (supporting 768 MB or 1536 MB of GDDR5 memory). Expect more details to come out in the run up for end-August.
