Lenovo Has a CXL Memory Monster with 128x 128GB DDR5 DIMMs

Assuming 8MB per instance, in theory I could run over 2,000,000 copies of DOOM on this thing at the same time.

Would love to know what the framerate would be

Hope I get crazy rich one day so I can spend money doing stupid stuff like this.

Now you just need to figure out how to simulate transistors in an instance of the game, so that you can port DOOM to run on a 2,000,000 transistor DOOMputer.
