How much faster is a 64bit CPU than 32bit CPU? [closed]
- by W.N.
I just need the result in theory. I'm not an expert in computer architecture, just a software developer.
Most of my friends think 64bit-CPU is 2 times faster than 32bit-CPU. But I think 64-CPU is 2 ^ 2 = 4 times faster than 32bit-CPU (in theory).
Which is the right answer to this question? And, if there were 128bit-CPU, how many times would it faster than a 32bit-CPU?
PS: I searched with Google, and found a link that referred to benchmarks that supported my answer.
I've seen a benchmark where 64bit was 4x faster but that was with a
particular encryption where the extra registers available made the
difference
