The 1 kbit RAM chip probably also would have difficulty running at 166MHz. That being said, having the master clock of the system running at 166MHz doesn't mean the entire thing does. You could use a high clock rate to generate a video signal but have the actual logic of the system behind a clock divider running at a much lower frequency.
- dahart 4y agoMy hardware design prof in undergrad had a story about one of the chip manufacturers having some cray fast internal clock in the 70s or 80s that was running microcode to implement the processor’s ISA. In my (probably faulty) memory I think the story was something like 800 MHz made by a weird brand (weird to my naive undergrad brain) like Rockwell or something, while the instruction clock presented to the user was maybe in the single or double digit MHz. No idea if I’m remembering right, and my Google Fu is failing to verify this story. But anyway, to your point, modern GPUs have a bunch of different clocks for different sub-systems.
