Latest NVIDIA GeForce RTX 4090 Rumors: AD102 GPU, 24 GB of 21 Gbps Memory, 600-Watt TGP


Prominent leaker kopite7kimi has returned for another episode of, “How powerful might NVIDIA’s next flagship graphics card be?” The leaker had suggested earlier this month that the GeForce RTX 4090 will feature the Lovelace-based AD102-300 GPU and 24 GB of memory with a blistering speed of 24 Gbps and 600-watt TGP, but these specifications have apparently undergone at least one notable revision since the initial report. According to the latest from kopite7kimi, the memory clock specification of NVIDIA’s next-generation BFGPU has seen a downgrade to 21 Gbps, a figure that would put it right in line with the GeForce RTX 3090 Ti’s GDDR6X. Unfortunately, there’s no change to the alleged, ridiculous 600-watt power consumption of the GPU.

NVIDIA’s Next-Gen ‘Ada Lovelace’ GPU Powered Flagship GeForce Graphics Card Rumored To Feature AD102 GPU, 21 Gbps Memory, 24 GB Capacity & Up To 600W TGP (Wccftech)

There might be a new rumor surrounding the naming convention used by the next-gen GeForce graphics cards with some now pointing towards a name change to GeForce RTX 50 series instead of the previously expected GeForce RTX 40 series. In the end, whatever NVIDIA decides to call the next GeForce lineup isn’t as important as its underlying specifications.

We know from the leaked NVIDIA Ada Lovelace GPU configurations which show that the flagship GA102 Gaming chip will rock a total of 144 SMs, a 71% increase over the existing GA102 GPU, and house a massive 18,432 CUDA core count. The chip used by the flagship GeForce graphics card will rock the AD102-300 GPU and we can’t say for sure if this will be the full-fat SKU since the RTX 3090 Ti with the GA102-350 rocks the full configuration while the GA102-300 SKU featured on the NVIDIA GeForce RTX 3090 is a cut-down SKU.

According to Kopite7kimi, the flagship GeForce graphics card will be based on the PG137/139-SKU30 PCB. These are both reference and Founders Edition designs. The reference design is provided to AIBs as a reference for their custom models while the FE design is exclusive to the reference Founders Edition model.
