I am not always right. But a pure comparison of CPUs is not sufficient. Read here, for example, about the difference between SD-RAM and DDR2-RAM:
https://www.transcend-info.com/support/faq-296#:~:text=DDR2 SDRAM(Double Data Rate,(double of DDR SDRAM).
Maybe now you'll realise what I'm talking about. And apart from that, an Intel Pentium 4 is not the same as an Intel Pentium 4. There were different series like Willamette, Northwood, and Prescott. And within these series different FSB clock rates. So, forget about these comparison sites! The only way to compare our computers is doing the same test regarding all hardware components.
P.S.: Due to my motherboard layout, there are several bottlenecks. Firstly, the extremely slow SD-RAM memory, then the very low bus clock rate and finally the AGP 4x interface, although my graphics card actually is an AGP 8x one.
