Multimedia is important for some uses, not for others. And what speed G4, against what speed Pentium 4? G4 started from 450 MHz and went to 1.6 GHz, with several different µarch along the way. Conversely, the Pentium 4 ranged from 1.3 GHz to 3.8 GHz. G4 and P3 at least covered a nearly identical MHz range, and with similar MHz in the market at the same times.

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.

  Core Duo's are almost duct-taped PIIIs.

    Isn'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...

      Which given hardware description languagesm that might indeed have been in the case. :)

The a version of the Pentium 4 was slower than the Pentium IIi per clock (launch model) and used goofy rambus memory

  Their prediction about rambus hasn't aged well, but the technical advantages vs. SDRAM of the time are still interesting: https://www.hardwarecentral.com/sdram-vs-rdram-facts-and-fantasy/ https://www.hardwarecentral.com/sdram-vs-rdram-facts-and-fan... Surprisingly enough the N64 used RDRAM (and supported a memory upgrade, lowering the cost of the console at launch but enabling an upgrade path for games that needed more memory.)

It actually was between PIII and IV on capabilities. Altivec allows to play h264 videos on some settings. A Pentium III, well, SSE and FFMPEG can do magic, but not as well as Altivec. SSE2 it's better, much better. Basically the minimum for x86 and 'modern' browsers. On the architecture itself, PowerPC did far more per cycle.
