Have only just learned about processors with 'extensions'. Apparently, one can have an X86 processor with 64bit extensions. Seeking guidance on how this works.
- Does an X86 processor perform 64bit processing?
- Could such a processor meet the requirements of software designed for 64bit processing?
- Who makes such processors/
- Would an image of such a processor have distinguishing features that could be seen?
Much thanks in advance for an informed opinion
