Which operator is faster: != or >

Question

Which operator is faster: > or ==?

Example: I want to test a value (which can have a positive value or -1) against -1 :

if(time > -1)
// or
if (time != -1)

time has type "int"

Answer 1

The standard doesn't say. So it's up to what opcodes the given compiler generates in its given version, and how fast a given CPU executes them.

I.e., implementation / platform defined.

You can find out for a specific compiler / platform combination by looking at / benchmarking the executable code.

But I seriously doubt it will make much of a difference; this is the kind of micro-optimization that is almost always dwarfed by higher-level architectural decisions.
