Just teasing. :wink: The idea of the extra 1MB of cache is to keep the processor from having to go to main "system" memory for instructions/data, as the cache(being on the CPU die) is faster to access. In reality though, especially on Pentium D, the extra 1MB cache(per core) doesn't give much performance gain at all. :)

I would have told him 8,192,000 bits.
Just my 2 bits worth.

1 meg is 1000 kilo, which is 1000 1000 bytes or 1000000 bits, therefore the difference is 1,000,000 bytes that can be stored :)  .... unless you use the digital definition of a thousand which is 1024.


But we are talking of a CPU's SRAM cache, and the way the gates are arranged, they will always be MiB not MB :p 

Therefore, it will be 1,024 KiB, or 1,048,576 Bytes, 8,388,608 bits :p 

In fact, although you would know this better than me, there may be more cells to add some redundancy in case of die faults, although you'll only ever access 2MiB on a Cedar Mill.
