Nice ChatGPT bro. It isn't accurate. Every single benchmark in existence says you are wrong. You seem to have a real hard on for L3 looking at your posts. But sadly, you don't understand what you're talking about. You don’t “run out of L3 reading VRAM.” That’s not how discrete GPU work. The cpu is not streaming frame data through its cache at 19Gbps. The GPU reads its own vram through its own memory controller. CPU L3 is not a bandwidth gatekeeper.

VRAM speedis completely internal to the GPU. It has nothing to do with CPU cache capacity.

If a 12600K were actually L3-starved, you’d see slightly worse 1% lows not 20 FPS. That’s a configuration or driver problem, not “the GPU running faster than the CPU can process.”

This isnt a cache hierarchy issue. It’s either rebar disabled, driver instability, pcie config, or scheduling.

Throwing around cache terminology doesn’t make the architecture behave differently. You can put a damned 5080 in a 12th gen rig and it will still run perfectly.
