Pentium 4 had an exceptionally long pipeline to be able to hit higher frequencies, trading-off high IPC numbers in the process, most of the time. On top of that, Pentium 4 also “looped” the same instruction while waiting data resulting in lower efficiency and higher heat output.
So, I assume, they are “step by step” comparable. i.e. slowest P4 equal to slowest G3 and they are again equal at next stepping and so on.
- anthk 1y agoCore Duo's are almost duct-taped PIIIs.
- bayindirh 1y agoIsn't Core Duo is an evolution of Pentium-M which is an evolution of Pentium 3, omitting Pentium 4 in the process like an unwanted child? Feels like they rolled back a couple of commits, forked to a new branch and started over...
