GeForce RTX 4080 and 4070, more variants in the study: everything can still change .. or maybe not?
Rumors continue to circulate about video cards from NVIDIA GeForce next generation, especially on the GeForce RTX 4070 and Sulla RTX 4080. Although the announcement of the new generation is expected at the end of the month, in view of a debut starting in October, the technicians of the US company would still be deciding the specifications.
The leaker kopite7kimi believes that NVIDIA is still working on the final specifications of the GeForce RTX 4070. A variant, which until a few days ago seemed to be in pole position, would have an AD104 GPU with 7680 CUDA core and 12GB of GDDR6X memory a 21 Gbps su bus a 192 bit.
The other solution in the laboratory, on the other hand, would have the same GPU but with only 7168 CUDA active cores, flanked by just 10GB of GDDR6X memory at 21 Gbps on 160-bit bus. The TBP – Total Board Power – of the first board would be equal to 285W, while the second solution would stop at 250W.
Review the two possible specs of RTX 4070:
PG141-SKU340/341, 7680FP32, 12G 21Gbps GDDR6X, total card power 285W, TSE PG141-SKU336/337, 7168FP32, 10G 21Gbps GDDR6X, total card power 250W, TSE I found that I had made a typo before, mistaken wrote 341 as 331. 😅

As for the GeForce RTX 4080the leaker MEGASizeGPU claims that the partners would have access to two projects, one with 12GB and one with 16GB of GDDR6X memory. In the first case the board would have a PCB with 10 layers, in the second a 12 layer. The leaker speaks instead of a 14-layer PCB for the RTX 4090 with 24 GB.

4080 16G GD6X 12layer PCB aic
4090 24G GD6X 14layer PCB aic reference design
note：4080 12G has a completely different pcb design from 4080 16G

Both in the case of the RTX 4070 and in that of the RTX 4080, it does not necessarily mean that two models will arrive on the market under the same name. Perhaps NVIDIA just wants to throw some smoke in the eyes of leakers and competitors, or is just working on more solutions and configurations, in view of possible updates to the range if necessary. The truth will emerge in the next few weeks.
