AMD vs. Pentium speed

How can a 2 gigahertz athlon processor act like a 3 gigahertz pentium? My dad says it is because of the "architecture" but what exactly does that mean?
 
Well, what he's really talking about is the fact that per clock cycle, let me see if I can get this right, Praetor, AMD chips do more calculations. So, the actual clock speed (MHz) is slower, but performs just as well because it's basically more efficient.
 
Making a choice between the two brands is simply based on what you do the most. Gaming=AMD, Video and Image editing=Intel.
 
i dont really care myself i dont find a large difference in cpus of around the same price intel and AMD i bought amd bc i wanted to get a 64bit cpu
 
I buy AMDs, because im a fanboy. hahaha. Its halfway tue though, and the other half of it is becuase im a gamer and i have gotten much better proformance out of them compared to my piece of !@#$ Celeron D 2.8Ghz.
 
I'm not buying a new computer within the next 6 months, but I mostly do gaming and a tiny of photoshop just for fun (I guess that's photoediting) so what would I be better off getting? Also should I get a dualcore? Probably a wierd question because thechnology changes so quick but... yeah.

An Athlon64 X2 would fit that bill nicely: the ondie memory controller helps wit the gameing and the dual core for the hevay work stuff :)
CPU 101.

I hear ya celerons suck I had a celeron laptop that sucked...

1. He said CeleronD. Not Celeron. Big distinction
2. Odds are its not the CPU thats bottlenecking gameplay but rather the VC (hence CeleronDs get a bad rap because people who buy CeleronDs dont often buy mid/high end VCs and thus dont get gaming performance)
 
here goes nothing. a pipeline is a long string of instructions. these are called stages of instructions. it takes one clock cycle to perform one stage of instruction. with intel, at each of these execution pipelines, they break down instructions into smaller chunks and this results in pipelines that go as long as 30 stages. so it would take 30 clock cycles to execute all 30 stages. with amd their pipelines only has 12 stages (as far as i can remember). that means they only need 12 clock cycles to perform the same amount of instructions. so at each cycle they perform more instruction executions. so in order for intel to keep up, they have to increase the clock rate at which each stage is executed.

heres an analogy i developed. a bakery is called intel and amd. they need some wheat so they call their supplier across the street. intel uses ferraris to ship the wheat and amd uses semi trucks. the ferraris take off at 150 mph across the street and there is 30 of them. while on the amd side they have 10 semis truck that slowly make their way and then all the wheat is dumped at the plant. do you see which one is more efficient? yes the ferraris are going faster but the semis are getting more done at one moment.

hope that helps

wow your analogy was dumbed down to an extreme! lol
 
I liked your analogy cuz im not really into how the processors work just as long as they get the job done, so the analogy really pointed it out to me better than stuff about "pipelines" and all that...
