Hi one thing i have always wanted to know is why AMD show the speed of their processors differently.

I have looked around but cant seem to find the answer im looking for.

So For instance Intel Pentium 3.2ghz, simple.

But AMD its like 3400+ (2.2ghz) why have they done this.

So out of the 2 above samples who would come out on top and why?

Thanks
 
AMD naming convention show the equivalent speed pentium the processors match up to/beat. You'll find clock speed no longer matters, as the more advanced the architecture of a processor the less cycles must be taken to process data.
Intel Core2Duos have low clock speeds compared to the pentium 4s, but the single cores on the processors match up to the pentium 4s, as they are so efficient.
AMD will most likely stop naming their processors how you'v stated, due to Intel stopping the clock-war, and since the core2duos out perform AMD chips, even at lower clock speeds :)
 
oh and the other question, as to who would come out ontop, the AMD should since its rated a 3400 and the pentium a 3.2, generally depends on what you're running though, look at them as being somewhat even performance
 
Ah i see.

So the AMD 3400+ would match, beat, a Intel 3.2ghz - 3.4ghz for example becuase it uses more clocks per cycle but now the Core2Duos use even more clocks per cycle is that right?
 
nooo, wrong wording but ** following.
The AMD doesnt need to be clocked as fast to do the same processing as the P4, and the core2duos can be clocked at even lower than the AMDs to do the same work.
Basically now clock speed means practically nothing.

when you are looking at chips from different 'families'

when your looking at chips from the same family, ghz is then important.
 
Basically, its like the difference between 3 runners legs (bear with me lol)

So a Pentium 4 goes at 3 meters per second, but has small legs, so has to move their legs faster

a AMD A64 goes at 3 meters per second, but has medium legs, so can move the same speed but with slower leg movement

and a Core2Duo goes at 3 meters per second, and has long legs, so can move at the same speed but moves his legs very slow!

therefore, if the A64 and Core2Duo legs moved as fast as the Pentium 4's, the A64 would be moving at say 3.4 meters per second and the Core2Duo at 3.7 meters per second.

Legs = processor speed. (the smaller the legs the higher the clock)

Therefore if you increase clock speed (decrease leg size) the others can move even faster than something of the same size/clock!

I explained it to my wee bro that way and he understands now (that i'm mental) ;)
 
you'v taken it out of context, yes it does matter when its in the same familys of chips, but it was being explained between different familys. Oh the chew.
 
Dunno what you on about

Intel Pentium 4 524
Intel Pentium 4 541
Intel Pentium 4 820
Intel Pentium 4 915
Athlon 64 3700+
Athlon 64 X2 4200+
Intel Core 2 DUO E4300
Intel Core 2 DUO E6300

Where does the naming scheme of any CPU now days mention clock speed??
 
It's a performance index. Something AMD implemented on socket A to stop people merely buying based on clockspeeds, when their chips, although operating at a lower clockspeed, did more work than an equivalently clocked Intel processor.

Intel have now done the same with C2D.
 
AMD use a P-Rating, that's Pentium Rating to you and me. It's basically the equivalent speed of a P4, so 3400+ would have a p-rating of 3.4Ghz, whereas a 4600+ would have a p-rating of about 4.6Ghz, if it was an Intel. The FarCry manual is the best comparison, just look on the 2nd page and notice the different ratings, a P4 2Ghz = Athlon XP 2000+, a P4 3Ghz = A64 3200+.

This no longer applies since the C2D's, and the new AMD competitiors, have 'insane' amounts of cache. And with the speed it runs at, you end up with > 40GBps's (or 5Gbps) of bandwidth!
 
No it's Performance rating and its comparable to what an old Athlon Thunderbird core would need to be clocked at to perform the same. Nowt to do with Intel or Pentiums ;)

That's correct.

Just because a P4 3.2GHz Prescott can encode media very fast, doesnt mean that it would give the same good performance gaming wise as compared to a S939 3200+

It used to be to do with the on die memory controller on the A64 and the massive L2 cache's on the P4's - but Core2 has levelled it out and redesigned completely from ground up, basically combining the cache advantage of a P4 and the on die memory controller of the A64.

But that's just my view on it.
 
Isn't it down to the pipelines in AMD cpu's and Intel cpu's?

AMD have more and shorter pipelines than Intel cpu's hence why Intel's have always been clocked faster and better at encoding etc applications?

Core2 doesnt have an inbuilt memory controller..
its on the north bridge still.
the Core3 apparently will though.. maybe.
 
you need to take into consideration the ghz, bus speeds, cache, number of cores and the architecture before you can decide which is a faster chip. its not as simple as it used to be.

people overclock because not matter what chip speed you have you'll see an increase in peformance even if its only small.

i prefer the washing machine drum analogy i invented.

P4 3.0Ghz - small drum, spins really fast.
A64 3000 - larger drum, spins slower.

to wash the same amount of clothes the effect of the slower speed and smaller drum cancel each other out, making the performance relative. This would obviously change as the size of the drum, or the speed of the drum increase/decrease.
