One might question why an RX 9070 card would need so much memory, but increased capacity can serve purposes beyond gaming, such as Large Language Model (LLM) support for AI workloads. Additionally, it’s worth noting that RX 9070 cards will use 20 Gbps memory, much slower than the RTX 50 series, which features 28-30 Gbps GDDR7 variants. So, while capacity may increase, bandwidth likely won’t.
One thing that might also require more memory in the future is to do both at the same time (keep LLMs loaded while gaming).
There’s a Skyrim mod that uses (optionally) a local LLM to chat with NPCs. In addition you can also use speech to text and tts to just speak with the NPCs.
However, there’s a lot of lag to make it a proper experience.
I wasn’t so much thinking about use in games as just use in other software on the system that keeps running while the game is in use. The game can coordinate its own resource usage but independent software has a harder time with that.
