Already last week we were able to see the PCB of the RTX 3090 in an official video from NVIDIA, in which he explained in detail the design of its new GeForce RTX 30 graphics card. 24 GDDR6X memory bases are dying (12 back and 12 front), so it can only be in this model.
RTX 3090: Small 20-phase PCB
While the photos we’ve seen so far of the NVIDIA RTX 30 show us an enormous size (larger, in fact, than current models), it seems that this will be the case because of its large heatsink and not because of the large graphical PCBs. In contrast, the PCB has seen its size significantly reduced, but NVIDIA has significantly improved its capabilities.
The PCB incorporates 20 power issues, making it a ‘premium’ design even beyond the current graphics of the current generation. From what appears to be its electronic design, the GPU operates in 18 phases while the remaining two phases are available in 24 GB GDDR6X graphics memory.
A little more attention to the PCB of this RTX 3090 we can see the connecting designs of the video effects, where we find three ports DisplayPort 1.4a
In addition, the Founders Edition cards for the GeForce RTX 30 series will include power connectors Micro-Fit 3.0 12th pin. These connectors will not require you to change the power supply, as the graphics will include an adapter for using two 8-pin PCI-Express connectors in this new type of connection.
The discovery of this new 12-pin connector on the PCB is also noteworthy, and because it is placed in a vertical position and, judging from the PCB structure, it is not difficult to see why NVIDIA decided to change the connector on these graphs. The PCB is very compact as we have said before, and they have had to rebuild the power line and use this connector instead of the two 8-pin space-saving space. However, as always the reference design we are looking at may be bypassed by custom compiler designs.
Quick Ampere chart… and expensive
As you know at the moment we can only talk about speculation and leaks (although today we will probably know more official details), but from what we know so far RTX 3090 will be NVIDIA’s fastest drawings so far. I have GPU GA102-300-A1, with 5248 CUDA cores in 82 SMs. Overall, it has 20% more cores than the RTX 2080 Ti, and while there are no leaks yet to ensure the speed of its operation, it is not hard to imagine that the performance would be too high.
Of course, if the RTX 2080 Ti is an expensive design and can be reached by very few (even today their price is almost 1,200 euros), these RTX 3090 for the new Ampere building will be much higher. If NVIDIA does not guarantee its final value, in theory they will be close 1,400 dollars.
