Double-Whammy Look At The Pentium 4

SystemLogicNet writes: "We at SystemLogic.net have just taken a technical look at the Pentium 4 architecture. In the article we go over all the basics that all the other sites cover like the double pumped ALUs, iSSE2, the longer pipeline, etc, but in addition we have some discussion about how different program structurings have an impact upon the design, and performance of the Pentium 4. One of the major areas where this comes into play is how complex data structures interact with the underlying philosophy that the Pentium 4 is built upon -- extreme bandwidth. This Pentium 4 technical background can be read over here. At the same time, we've done a rigorous analysis, including benchmark description and discussion regarding the Pentium 4's performance, and this can be read over this way."

Re:optimized for Xtreme Programming? please.

And what is the success rate for the Athlon's branch prediction?

If you don't know this kind of stuff, then don't criticize Intel. Branch Prediction is hard stuff. If I asked you to do it with 90% accuracy, I bet you couldn't.

Whoever moderated this as offtopic is smoking crack.

This is one of the dumbest analogies I've seen. Mod the parent down to -1.

This is definitely true. The parent post is terrible.

Sad state of affairs

Wow, Intel really loves the MHz wars. Pumping out MHz when only 90% of the brancing is correct. Most of you probably think 90% is good, but think of it this way: 1 out of every 10 times you try and click on something, or double click something, or open a file, whatever, it fails. Every 10th Word file fails. This is good? Industry servers are designed for 5 9s (99.999% uptime), yet we can accept a 10% fail rate for our processors?

Also, the P4 needs a temperature shutdown?!?!?! Makes one think that even if Motoralla's Apple chips are lagging in MHz, at least they won't burn down your house!
