NVIDIA GeForce RTX 4090 Ti Allegedly Features Ada GPU With 18176 Cores, 24 GB GDDR6X Memory, 600W TBP

Specifications of NVIDIA's GeForce RTX 4090 Ti graphics card have once again been revealed by Kopite7kimi which show vastly different specs than the Titan variant that is also reportedly in the works.

The NVIDIA GeForce RTX 4090 Ti graphics card has been rumored for a long time but according to the latest information, it looks like the card is a whole different entity. Previously, it was expected that the card was going to be branded as another Titan product but this specific variant is clearly going to be used by the GeForce RTX family while the possibility of the Titan variant still exists. It's due to the fact that the GeForce RTX 4090 Ti is expected to be based on the PG136/139-SKU310 & the Titan RTX "Ada" is expected to be based on the PG137 SKU.

Starting with the specifications, the NVIDIA GeForce RTX 4090 Ti is rumored to feature a slightly cut-down AD102 GPU. That's 256 fewer cores than the full configuration which includes 18,432 cores. It packs 18,176 cores which is an 11% increase in cores over the RTX 4090, 96 MB of L2 cache which is a 33% increase over the RTX 4090, and 24 GB of GDDR6X memory. While the memory capacity still remains the same as the RTX 4090, the bandwidth will see a major boost.

Compared to the 21 Gbps dies featured on the RTX 4090, the NVIDIA GeForce RTX 4090 Ti might be packing 24 Gbps dies. This is going to provide a bandwidth of up to 1.15 TB/s, an increase of 150.0 GB/s over the Non-Ti variant. The TBP of the card is also lower than the 800W monster the Titan is going to be. It is expected to be around 600W but does note that this is the board power and not the TGP which might be lower.

A single 16-Pin 12VHPWR connector should be enough to feed the reference design but it looks like custom models may have to rely on dual 16-pin connectors or restrict their clock speeds to meet a conservative 600W power limit to allow for single connector designs. As for the cooling solution, we can expect to see the standard flow-through design for this variant but in a much heftier graphics card heatsink package that covers quad slots.

There's no word on when the NVIDIA GeForce RTX 4090 Ti would launch but it should cost around $2000 US. The only two major events in the coming months are going to be GDC and GTC so maybe we get to see a teaser or glimpse of either the new Ti or the Titan at the event.
