I haven't paid attention to GPUs since I got my 3080 on release day back in Covid.
Why has acceptable level of VRAM suddenly doubled vs 4 years ago? I don't struggle to run a single game on max settings at high frames @ 1440p, what's the benefit that justifies the cost of 20gb VRAM outside of AI workloads?
An actual technical answer: Apparently, it's because while the PS5 and Xbox Series X are technically regular x86-64 architecture, they have a design that allows the GPU and CPU to share a single pool of memory with no loss in performance. This makes it easy to allocate a shit load of RAM for the GPU to store textures very quickly, but it also means that as the games industry shifts from developing for the PS4/Xbox One X first (both of which have separate pools of memory for CPU & GPU) to the PS5/XSX first, VRAM requirements are spiking up because it's a lot easier to port to PC if you just keep the assumption that the GPU can handle storing 10-15 GB of texture data at once instead of needing to refactor your code to reduce VRAM usage.
Perfect answer thank you!
