Will the 10GB of the RTX 3080 fall short in future?
According to NVIDIA's own information from a Q&A session, tests with popular games like Borderlands 3 and Assassin’s Creed Odyssey at 4K showed that only 4 to 6GB of VRAM (actual) were used. NVIDIA claims that the 10GB in the RTX 3080 strikes a good balance between cost and future-proofing, based on their testing.
