clockspeed:
-> what does GHz really mean everytime you click the simulation is one cycle.
A typical cpu of 3 GHz will execute 3.000.000.000 lines of code per second per core
So if you have 4 cores it can execute 12.000.000.000 lines of code per second.

Multicore:
It is not easy to use all cores on a desktop environment, even in games the GPU will be used in stead of the CPU but perhaps in video-”rendering” which can happen on the fly in games too the power of all cores can be harnessed.

Verschil tussen 64 en 32 bit:

http://en.wikipedia.org/wiki/64-bit_computing
MORE addressable memory:
memory in 32bit goes to 4billion positions (max 4GByte RAM)
memory in 64bit goes to 18x1018 positions (max 18 EXAByte RAM) (maar kan het OS dat aan?)
MORE space needed:
the same data occupies more space in memory (due to longer pointers and possibly other types, and alignment padding -> 64-bit programs use about 50% more memory)
64-bit mode processor has more registers, so it doesn't need to access memory that often, also, some calculations (64-bit numbers etc.) are more efficient. So generally, code which is not memory-restricted runs slightly faster in 64-bit mode.
FASTER execution:
64-bit is generally faster, even if objectively hard to notice. This is has less to do with the 64-bit data width, but with the availability of 16 over 8 common CPU registers on the whole instruction set.
