processor guide.. need help

im getting confused with amd and intel processors (amd 64 vs intel p4 HyperThreading)


explain to me how amd processors are better for gaming yet for the same price, i can get a p4 3.0 ghz compared to a amd 2.2-2.4 ghz

so when im not talking about gaming, does pentium 4 win over amd?

 
Now now mr Marine, no need for hastiness.

Hey Naruto my man, get yourself an X2, IT's a TRUE dual core. Hyperthreading is software emulation that is coded for a P 4 to create pseudo threading basically.

2 physical cores exist on the 64.

x2 3800+ NO QUESTIONS ASKed man!
 
How do have nearly 700 posts here w/o understanding that clockspeed isn't the only factor in CPU performance?

HT is actually a hardware implementation of SMT. I'm not quite sure what you mean be psuedo threading, but what it actually does is use any unused resources available to the CPU to execute code from another thread. SMT is the future.

I would not recommend any A64 single core, unless you are really strapped for cash. As more software becomes SMP aware, the benefit from HT P4's will increase. New games that are SMP aware, such as Quake4, CoD2, etc, put the P4 6xx series above or at the PR rating for A64's.
 
Sorry I meant pseudo dual core, ADD.

Yeah, it's a code implemented physically in the p4 EMULATING 2 cores and in windows making it show2 cores when it is really one
 
well that was my understanding of it, what's SMT? I'm interested to learn a little more, always thought of it as dual core emulation
 
Well, for somebody to actually answer the man's question:
Put simply, AMD does more work per clock than P4. That's how a 2 GHz AMD can be just as fast or even faster than a 3GHz P4. That doesn't go for games only. There are of course scenarios where P4 is better and scenarios where AMD is better so having two overall equal processors (e.g. AMD 3.0 and P4 3.0 - not saying that they are, just an example), P4 will trounce AMD in media encoding while AMD will be much better in games, etc.
 
I'm talking about Hyperthreading and the comparison of dual cores and how hyperthreading works... we all agreed that a dual core amd is better than a hyperthreading single core intel

There's a huge debate thread in Arstechnica about SMT/HT/SMP.

http://episteme.arstechnica.com/groupee/forums/a/tpc/f/174096756/m/905006818731

The CPU is rarely 100% utilized in any task (and no, Windows Task Manager does not count). The idea behind SMT is to utilize those unused resources into another thread. Hyperthreading is Intel's version of SMT. It's not software based nor is it emulating anything; Linux and Unix will identify another core for scheduling purposes by the OS. SMT is the future. Virtually all new CPU's from various manufacturers (IBM, Sun, etc) coming out have it.

Contrary to what most AMD fanbois on the forum will have you believe, SMT is not due because of the "inefficiencies" of Netburst. A short pipelined CPU like the IBM Power or Sun Niagra also uses it.

true. that should be be the same for anyone who knows what cpu stands for. never is there just 1 factor.
 
Oh I see dex

I want to get into Technica but I hear it's very EE savvy and I do not want to get owned 🙁
