A lot of wait states in a CPU come from accessing memory outside of cache. If you make all the RAM in your system the same as cache, you'd get a huge leap.
If RAM clocked higher and pushed closer to a processing cpu would make everything 50 times faster it'd still need 20 times as much silicon. Considering ideal heat dissipation such a system would still need let's say 20x100w = 2kW of input power. Which is about what a fast boiling kettle needs. How much realistic is that?
Where do you get the 20 times as much silicon number? For example, SRAM typically uses 6 transistors per bit, as opposed to 1 transistor for DRAM. What are the other 14 transistors doing?
Yeah, that's an obvious one. Not sure how I overlooked that. Thanks.
