NVIDIA fans who have been speculating that green team’s next flagship gaming graphics card would feature a similar memory configuration as the current champion might be correct after all. Habitual leaker kopite7kimi has returned with some new rumors regarding the upcoming Lovelace-based GeForce RTX 40 Series, and they suggest that the GeForce RTX 4090 will feature 24 GB of 21 Gbps GDDR6X memory, just like the GeForce RTX 3090 Ti. The GeForce RTX 4080 and GeForce RTX 4070 will also supposedly feature 16 GB and 12 GB of VRAM, respectively.

The GeForce RTX 4090 reportedly rocks the AD102 die and is likely the flagship silicon for Nvidia’s next-generation lineup. The graphics card may arrive with 24GB of GDDR6X memory at 21 Gbps. That’s the same recipe Nvidia used for the GeForce RTX 3090 Ti. Therefore, Nvidia may not push the memory limit for this generation, seemingly maxing out at 24GB as the chipmaker did on Ampere.
