Source showed a couple of days ago a prototype of AMD Radeon RX Vega 56 with a dissipation system of three fans and a huge aluminum radiator that had nothing to do with the reference model.
It was not confirmed that it was a prototype Radeon RX Vega 56 and could be a montage, but in the end AMD itself has confirmed that it is a model that are testing some assemblers to create custom designs.
This means that the prototype is real and that what we see in the images could end up reaching the market, although the firm of Sunnyvale has not specified which assemblers are the ones who are considering the possibility of using that system of dissipation.
The AMD Radeon RX Vega 56 with the reference design and the turbine fan that incorporates that reach about 75 degrees at full load, so it is very likely that this set of three fans can reduce temperatures to close to 65 degrees.
Another thing that draws our attention is the presence of an 8-pin power connector and a 6-pin power connector, a major change over the two 8-pin connectors that use the AMD Radeon RX Vega 56 in its reference design.
This suggests that it would be possible to create a more efficient version of the Radeon RX Vega 56 and reduce its total TDP by 75 watts. The PCIE port delivers up to 75 watts and each 8-pin connector offers up to 150 watts, which translates to a maximum of 375 watts in the reference version, which would be reduced to 300 watts in that custom model.
As I said at the time the AMD Radeon RX Vega 56 is much more interesting than the Radeon RX Vega 64, although we will have to wait to see what the assemblers can do before drawing conclusions.
