A couple of days after pictures of the PCB and cooling assembly of the GeForce GTX 480 made it to the internet, fresh pictures emerged, this time of the GeForce GTX 470, the slightly toned-down part in the GeForce 400 series. The GTX 470, like the GTX 480, is based on NVIDIA's GF100 core. The reference design PCB is certainly shorter than that of the GTX 480, and compacts its resources. Since the GTX 470 has a 320-bit wide memory interface, it makes do with 10 memory chips, seen surrounding the GPU from three sides. A simpler VRM is used: 4-phase vGPU and 1-phase vMem. Power is drawn in from two 6-pin power connectors.
The fan connects over its usual 4-pin PWM-controlled line. Some smart compacting of components made space for two intakes to be cut out, which help the blower draw in some fresh air. The cooling assembly, again is compacted accordingly. Since these new pictures are more clear, we can see that the area over the GPU isn't devoid of a copper surface as earlier thought. In fact, as some community members observed, it is a base with copper heatpipes making direct contact with the GPU. The cooler has protrusions at the right spots to make contact with memory chips and MOSFETs. The GTX 470 is slated to be the more affordable of the GTX 400 series, which will be unveiled on March 26. Follow the source link for equally good quality photography of the GTX 480's PCB.
