AMD PCB may show Navi video card with gddr6

Images have appeared online of an AMD circuit board that can accommodate a gpu and gddr6 memory. Perhaps it is a printed circuit board for AMD’s upcoming video card based on the Navi GPU.

The pictures have been posted on Twitter and coming from a Chinese forum. It is an empty circuit board, on which there are no chips. However, various details can be inferred from the layout and existing pins. The YouTube channel Actually Hardcore Overclocking has done an extensive analysis.

The overclocker shows that the number of pins of the memory chips shows that it is gddr6 memory. There’s room for eight chips, so the card has a 256-bit memory bus, just like the GeForce RTX 2070 and 2080. That could indicate that it is a video card that competes with those cards, although it should be noted that AMD video cards have generally have a wider memory bus than Nvidia variants.

It can also be seen that the video card has an eight-phase VRM and that there is room to mount two eight-pin power plugs. This would allow the card to get a TDP of 250 to 300 watts. In theory, a higher tdp is also possible, but it seems unlikely that AMD will release a video card with a tdp higher than 300W. According to the video analysis, the pcb also shows connections for a blower fan. AMD often uses such coolers on its reference designs.

It is expected that AMD will use the Navi GPU on video cards for the mainstream segment. It would be successors of the video cards with a Polaris GPU, such as the RX 580 and relatives. At the end of May, AMD will probably give details about the Navi GPUs, in a keynote at the Computex fair.
