Here's the very first picture of an alleged upcoming NVIDIA flagship/halo product to be positioned above the GeForce RTX 4090. There are two distinct brand names being rumored for this product—the GeForce RTX 4090 Ti, and the NVIDIA RTX TITAN (Ada). The RTX 4090 only uses 128 out of 144 (88 percent) of the streaming multiprocessors (SM) on the 4 nm "AD102" silicon, leaving NVIDIA with plenty of room to design a halo product that maxes it out. Besides maxing out the silicon, NVIDIA has the opportunity to increase the typical graphics power closer to the 600 W continuous power-delivery limit of the 16-pin ATX 12VHPWR connector; and use faster 24 Gbps-rated GDDR6X memory chips (the RTX 4090 uses 21 Gbps memory).

The card is 4 slots thick, with the rear I/O bracket covering all 4 slots. The card's display outputs are arranged along the thickness of the card, rather than along the base. The cooler is a monstrous scale-up of the Dual-Axial Flow Through cooler of the RTX 4090 Founders Edition. The card is designed such that the PCB doesn't come up perpendicular to the plane of the motherboard like any other add-on card, but rather, the PCB is parallel to the plane of the motherboard. The PCB is arranged along the thickness of the card. This has probably been done to maximize the spatial volume occupied by the cooling solution, and probably even make room for a third fan. We also predict that the PCB is split in such a way that a smaller PCB has the display I/O, and yet another PCB handles the PCI-Express slot interface. Sufficed to say, the RTX 4090 Ti / RTX TITAN will be an engineering masterpiece by NVIDIA.
 
Personally, if this is true, I don't agree with the decision making. For consumers an RTX 4080ti would be a better option in my personal opinion.
