Pentium 4 and G4e architectural comparison
Ars Technica's Hannibal has written the first installment
of an anticipated two-part series.
This article will examine the tradeoffs and design decisions that the P4's architects made in their effort to build a MHz monster, paying special attention to the innovative features that the P4 sports and the ways those features fit with the processor's overall design philosophy and target application domain. We'll cover the P4's ultra-deep pipeline, its trace cache, its double-pumped ALUs, and a host of other aspects of its design, all with an eye to their impact on performance.
