@ncrkel How does a transistor work? In a CPU I mean.

512kb l2 lol

@stephenlandrum there is a difference - but many users may not find it to be notable one...

@ncrkel my laptop has 1TB of L2-cache, just one aspect of the many amazing specs of my mind boggling laptop, also it has mind sync which connects via a form of wifi directly to the users mind for faster user interface.

No, we always need cache-memory on the cpu, beacuse the latency on main-memory is a lot slower than latency on cache-memory, so L1 and L2-cache will always be much faster than main-memory. And besides, main-memory uses DRAM or 1-bit per transistor wich is slow when cache-memory uses SRAM with 4 transistors per bit and that kind of RAM is both fast and expensive and can therefore not be used on main-memory, wich should then be very very expensive.

24mb L2 WOOP!

@3D8n52DmV37EI6oHeX RAM speed is limited by frontside bus speed, in other words, how fast can data flow from RAM to the processor. The access time of data in RAM is inconsequential if you're limited by a 800 MHz bus.

That's why cache exists, it allows you to load chunks of commonly used data onto the processor, so that it can be accessed without using frontside bus, thus only limited (mostly) by the speed of the processor itself.
