Why does AMD CPUs perform better than Intel CPUs?

[chingy1788]

First off... from a past post...
According to the Australian Personal Computers Magazine, October issue 2005 Vol 25 No 10...
The P4, pretty much every model, has worse performance, in Multimedia apps, Office activities and Games when compared to AMD CPUs, also Intel CPus are hotter(literally) than its corresponding AMD cpu... The sempron 3300 actually beat the P4 Extreme Edition in a multi media benchmark!!!
The P4 Extreme Edition fried an egg

"AMD's Athlon 64s were the clear Victors"

Benchmarks carried out on the following CPUs
Athlon 64 4000+ P4 670
Athlon X2 4800+ Pentium D 820
Athlon FX 57 Pentium Extreme Edition
Sempron 3300 Celeron D 351

I suggest you buy your self an APC mag if ur in aust... from any Newsagent or Coles/Woolworths Supermarket

Did i mention AMD is also Cheaper than Intel too?
AMD cpus, according to PC upgrade Booklet, by the makers of PC powerplay, say that when a new amd cpu is put out, it will work on motherboards that have the same socket, supported FSB only needs a Bios update(remember the Socket A?)... while intel CPUs when new ones released, need a new board

My question is
Why can AMD offer better performance, yet keeping the CPU cooler and cheaper than Intel?

AMD processors do not always offer better performance.  In office settings the P4 w/HT will generally perform a better than a AMD processor (when tested in a real world situation).  Intel processors are generally better when it comes to video editing, sound editing, etc.  However, AMD processors stomp most Intel processors (with the exception of the Pentium-M).

I can't remember the exact reason as to why AMD performs better in most cases but I believe it has something to do with AMD's pipelines being shorter while Intel uses longer pipelines.

AMD processors are cheaper because they don't have as big of marketing budget as Intel.  Think about it.  How many times have you seen AMD ad/commercial.  Now compare that to the number of times you have seen an Intel ad/commercial.

well when it comes down to the dual cores amds cores are about over each other just slighty over the pipelines go side to side as the intels cant go side to side so they have there 2 cores complety apart and one pipline goes out the bottom and in the bottom of ther other core and top to top witch slows down data

amd has 2 piplines working together

intels i like one in and one out

im not 100% how the pipelines work but that is how they are set up

Essentially, the AMD architecture is slightly different to that of the Intel chips.

This difference effectively allows the AMD to do more 'work' per clock cycle producing the same performance at a lower speed. The last time I read any tech articles, the AMD's at that time read/wrote data twice per cycle as opposed to Intel's once.

As they run slower, they produce less heat, making the equivalent power Intel run hot in comparison.

This means that you buy an Intel 3200 MHz processor which runs at 3200 Mhz, whereas you buy a 3200+ AMD which only runs at 2200 MHz. Same power but lower MHz and given the choice, Joe Public buys things with bigger numbers so AMD decided to sell using a PR (Performance Rating) value rather than the exact MHz speed.
