16 & 32 bit vs 32 bit only instructions for RISC.
The situation is not so clear with regards to 32-bit vs. 64-bit. When was the last time you needed an integer larger than 4e+09? Having said this, I have to say that a CISC processor is less likely to be able to utilize the increase in width without other advancements (ie. superscalar vs scalar,

Look around for some results that compare 32 bit VS 64 bit encoding. I would expect about a 20-40 percent increase in performance over an Intel...but that's However, my dual Athlon MP2000+'s cannot cope with when the slider is set all the way to the right - ie at 100%. How does your dual P4 cope with encoding

PKS 5.0: puzzled by 32-bit vs 64-bit performance
So, while 16-bit variable-length instructions with a 32-bit data bus may be a ] win on a machine with slow memory access time and no cache (ie your typical ] microcomputer, at the moment), 32-bit fixed length instructions with a 64-bit ] instruction-fetch memory interface will blow it into the weeds come

Why are 32 bit better than 16 bit pgms?
Defining dcas for v8plusa and v9 is a little tricky, due to 32-bit vs. 64-bit registers, and gcc asm notation is painful. Explicit memory barriers aren't needed for the SPARC CAS and CASX instructions, but are needed for the dcl routines (ie relaxed memory models). Most of the ideas/code can be gleaned from the

16 & 32 bit vs 32 bit only instructions for RISC.
A bit is a single binary digit, ie a 0 or a 1. Where is the contradiction? 32-bit computers have different instructions sets than 64-bit computers. Partially true: 64-bit This isn't the right forum for discussing computer architecture, but your understanding of 32-bit vs. 64-bit difference is quite incorrect.

32 Bits vs. 64 Bits in 1998
Even if you are talking about the same processor, .ie an Athlon 64 running a 32 bit program or a 64 bit program it's still meaningless because different pop 64 bit registers on to the stack instead of 32 bit registers. The bottom line is that there is no one answer about what the performance of 64 bit vs 32 bit is.

Perhaps I should have made the above a bit more clear, I was talking about 32-bit vs. 64-bit code on the Athlon64/Opteron, and NOT about 32-bit code on the AthlonXP What I meant by the above is that the most common uses for 64-bit variables in the "standard" applications that most users run, ie office suites,
