the caches are already ~75% of the space. you can't significantly increase that. On die ram is also relatively unlikely due to process differences. my best guess is more 3d cache chips. if we can get the interconnects small enough and fast enough, I could see a future where the logic is stacked on top of a dozen (physical) layers of stacked cache
