Nvidia GeForce RTX 4080: High-end Ada Lovelace graphics card could be offered in 12 GB and 16 GB flavours at launch
The yet-to-be-announced Nvidia GeForce RTX 4080 has received quite a few specification changes over the past few weeks. The latest rumour suggested it would pack 16 GB of 23 Gbps GDDR6X VRAM on a 256-bit bus. Now, Twitter leaker @Zed__Wang says that there are two GeForce RTX 4080 models in the pipeline, and the second one will feature 12 GB of video memory. Nvidia is also planning to launch both versions together.
Unfortunately, the leaker doesn't delve into the specifications of the model, merely stating that the Nvidia GeForce RTX 4080 12 GB variant uses a 10-layer PCB design instead of the 12-layer design used by the 16 GB version and that both are radically different. Both models will likely use a cut-down AD103 GPU with a varied CUDA core count. However, Videocardz thinks that the GeForce RTX 4080 12 GB could use an uncut AD104 GPU instead, based on recent Tweets by Kopite7kimi.
While Nvidia is no stranger to launching two graphics cards with different configurations together, the practice is usually reserved for lower-end offerings such as the GeForce GTX 1060. Applying the same principle to expensive, highly sought-after SKUs such as the GeForce RTX 4080 makes little financial sense. Nvidia's decision to discontinue the GeForce RTX 3080 12 GB's production mere months after launch suggests that the company wasn't too happy about cannibalizing its lineup and it is unlikely to repeat the same mistake.
