#2Can someone explain if the 3D Vcache are stacked on top of each other or side by side.
If they are stacked then why not 9800X3D2?

The 99xx chips have two CPU dies, and one cache die is on each CPU die.

#4Crazy to think that my first personal computer's entire storage (was 160MB IIRC?) could fit into the L3 of a single consumer CPU!
It's probably not possible architecturally, but it would be amusing to see an entire early 90's OS running entirely in the CPU's cache.

IIRC some relatively strange CPUs could run with unbacked cache.

Intel's platform, at the very least, use cache-as-ram during the boot phase before the DDR interface can be trained and started up. https://github.com/coreboot/coreboot/blob/main/src/soc/intel...

#9I have a gigabyte of cache on my 9684x at home!

In my case it began with 16K (yes, 161024 bytes) and 90K (yes, 901024 bytes) 5.25" floppy disks (although the floppies were a few months after the computer). Eventually upgraded to 48K RAM and 180K double density floppy disks. The computer: Atari 800.
