48 GB GDDR6X at 800 Watts consumption?

This is the evening news: the leaker @kopite7kimi on Twitter talks regardinga huge GPU from home NVIDIA. Indeed, according to him the AD102 GPU would feature a new PG137 board design. As a reminder, the PG139 card represents in principle the RTX 4090. Concretely, this PG139 board (NVIDIA RTX 4090 Ti/TITAN) would include 18,176 CUDA cores, 48 GB of 24 Gbps GDDR6X memoryall for un TBP d’environ 800 Watts. Note that this is not the first time that these characteristics have been mentioned. Indeed, at the end of April we were already talking regarding an NVIDIA GeForce RTX 4090 Ti/Titan with these specificities. With the difference that it was a question at that time of 900 Watts of consumption.

And it’s once more regarding an NVIDIA GPU with 800 Watts of consumption

Also note that some time ago we had some rumors regarding the design of a three-fan cooling system. Well, this one might take on its full meaning precisely for this card with a consumption to make Greta Thunberg furious. Likewise, if all of this is true we would also see a card with two 16-pin PCIe Gen5 connectors (12VHPWR). Remember that this new connection allows you to supply up to 600W via a single cable.

To come back to the GPU, we would therefore be on the full AD102 GPU with 142 SM and therefore 18,176 CUDA cores. This represents 11% more cores than the RTX 4090. As for memory, not only will we have a doubled amount (48 GB instead of 24 GB), but it will also be faster going from 21 to 24 Gbps. This would generate a memory bandwidth of 1.1 TB/s.

Finally, remember that at present there are still many unknowns. Moreover, nothing proves that this card will really arrive on the market, even if NVIDIA is working on such a model. Maybe it will be a non-consumer model, or it will be an RTX 4090 Ti that NVIDIA will sell as pro cards like the RTX 3090 Ti, but partner brands will sell as the best gaming card.

Remember that we are slowly starting to approach the theoretical dates of announcements and the launch of these RTX 4000s. In writing, we are looking forward to it and have already started to refine our test protocol to go further.
