NVIDIA GeForce RTX 4080 reportedly includes 16GB and 12GB memory versions, leaked PCB details are revealing. There are also more details about the RTX 4090 model, which will be at the top of the range of the series. Check out the complete details below.
NVIDIA GeForce RTX 4080 Comes in 12GB and 16GB Memory Variants
Apparently, the RTX 4080 model is going to have two different classes of PCBs, one that will come with 16GB of GDDR6X memory, while the other will have 12GB of GDDR6X memory. The former is going to have a 12-layer PCB, while the 12GB model would have a 10-layer PCB.
This information is important because it is suggesting that the RTX 4080 with 16GB would have a 256-bit bus, while the 12GB model would come with a trimmed 192-bit bus. If true, Nvidia will have to raise the specifications of other sections to compensate, such as the memory clock speed.
We also have to keep in mind that these are engineering samples and this could change from moment to moment, even PCB models could be discarded.

According to the data provided by MEGAsizeGPU, the 4090 model will have 24GB of GDDR6X memory with a 14-layer PCB, more complex than that of the RTX 4080.
The RTX 4090 graphics card will have a TBP of 450W, while the RTX 4080 would have a TDP of 350 TBP.
As for the launch, Nvidia should prioritize the cheapest model first, then debuting the more gifted variant if necessary. Remaining in the GPU field, the new competitor Intel has again spoken, through an interview with engineer Tom Petersen on the occasion of IFA 2022, of its top-of-the-range Arc A770 GPU, affirming a superiority in Ray Tracing over the RTX 3060.
According to the information we have, the RTX 4090 is going to be released first in the month of October. We don’t know if the RTX 4080 and 4070 will launch this year or have to wait until 2023. We’ll keep you posted.
