The Nvidia GeForce RTX 4080 is expected to be a solid graphics card capable of running games with high frame rates at resolutions such as 4K, but it will require a lot of RAM to fulfill its potential. Now, it appears that team green is currently working on two models, each with different levels of GDDR6X memory.
New messages from Twitter user Zed_Wang suggest that reference designs for a 12GB and 16GB version of the Nvidia GeForce RTX 4080 are being discussed, each with a unique PCB (printed circuit board) design. It's unclear whether or not the company will release two SKUs of the GPU, but it does suggest that we might get a nice VRAM boost over the RTX 3080.
Nvidia GeForce RTX 4080 with 16GB of VRAM would be the wise move if it were to face AMD in the race for the best graphics card, according to me. Radeon RX 6000 series pixel pushers already have this much GDDR6 memory, but capacity definitely matters more when it comes to gaming at higher resolutions.
AMD RDNA 3 GPUs will have the same powerful memory as current generation Nvidia graphics cards, but it's certainly in the team's interest to give the RTX 4000 series every benefit it can.
