wats difference between a 1mb cache and a 2mb cache

[CUTESEXYGUY]

hi guys hope u all well
maybe u could help me what the difference between a 1mb cache and a 2mb cache on a pentium d lga 3.0ghz processor
thanks

Just teasing. 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.

hey can i be your friend i got no freinds here
im running a pentium d 3.0ghz 1gb ram 80GB Seagate
nothing spectactular and a gigabyte mboard

are you gay? :roll:

are you gay? :roll:

His user name kind of exudes that, eh? :lol:

Is ya lookin' for a friend or someone with technical expertise to ask computer questions?

There's a BIG difference 8O

why dont u people like my name my gf gave it to me so how do i change it?
anyway thanks im not gay just looking for technical help

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

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

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.
