My response,


It is obvious that you don't know much about the development process of a microchip. they don't go from the drawing board to mass production in 2 months. Amd has had 1.1 ghz production silicon for 6 months now. when a cpu core is manufactured it is fabricated on a large wafer of silicon. The size of the core determines how many cores can be produced from each wafer. The individual cores are then tested for to determine what speeds they can run at reliability they are then marked and packaged for those speeds and sold. sometimes a core can be coaxed to higher reliable speeds by increasing the core voltage and improving the cooling of the chip these are tricks used by the over clocking community. there is nothing wrong with intel and amd doing the same thing to attain faster speeds IF! they know the processor is reliable.

You are correct the p6 core is core architecture and there have been enhancements to it to keep it competetive But it is still the same basic core. 6 years is a long lifetime for an x86 based core.

You ask how stable is that chip the Athlon? back up my sources. Sir I have been running Athlon systems since they were introduced and have found it to be the most stable platform I have used yet. Check any of the major hardware sites (ex. WWW.anandtech.com Or www.tomshardware.com) and read through their reviews and you will find that athlon based systems are just as stable as the most stable intel systems.

And Yes I am aware that the Athlon is a seventh generation core that was officially released to the public in June of 1999 and had been in development for 2 years previous to that. So what was the point of that?

Actually the fact that the Athlon has a " a 200 mHz bus,
> a dual ported 128 L1 split cache and an archetecture that includes a 3
> address calculation pipeline," Well at a glance that wouldn't seem impressive wouldn't it since p6 core also includes a 3 address calculation pipeline. "However in the case of the P6, the decoders cannot accept 3 complex instructions and process them simultaneously. In the case of the Athlon, regardless of the nature of the instructions, the decoding units are capable of decoding three instructions, regardless of nature, simultaneously." "Another point of improvement the Athlon offers over Intel's P6 core (yes, you read that right, AMD is not only going for competitive performance but they are looking to surpass Intel) is the accuracy of the processor's branch tree prediction.We've all met individuals that are undoubtedly predictable in life, whether it's because of something they always say or do, our minds get used to expecting a certain type of behavior from them when placed in a specific set of circumstances. The same applies to the Athlon, whose 2048-entry branch prediction table takes on the task of storing commonly used operations and attempts to predict what the next operation to come down the pipeline will be. Not only is the table 4 times as large as Intel's branch prediction table, but in the event that the Athlon incorrectly "guesses" at what the next operation will be, the penalty isn't as great as that of the P6 core. This is simply because of the Athlon's shorter pipelines (10-stage integer and 15-stage FP pipelines vs 15-stage integer and ~30-stage FP pipelines for the P6 core) which make sure that the Athlon doesn't have to start from scratch after a missed prediction.- Anandtech's Athlon Review Aug 9,1999

I have worked with a lot of amd and intel processors in the past 4 years and it has been my experience that in most cases any stability problems could be traced to flawed motherboard design or chipset design not the cpu itself. that goes for Intel and Amd.

I am sorry if I upset you All I was doing was pointing out that Amd has done a better job with the Athlon in the past year than Intel has with the p3.
 
Here are my original comments to him that got his shorts all in a bunch.>

Just read your comments in a talk back post suggesting that you think the
athlon cpu's are eventually going to have the same problem as the recalled
pIII's due to speed increases to quickly. You don't have the facts
apparently to understand exactly what is going on here. The PIII is built on
the p6 core architecture. that was originally the pentium pro cpu. That
architecture is 6 years old now and was never meant to scale over 400 mhz.
the athlon architecture on the other hand is a year old and was specifically
engineered to scale to the 1.6 gig range at the .18 micron die size. Amd has
had working production 1.1 gig chips since March. Amd at this time appears
to have the ability to bump up their clock speeds on their chips at will and
in volume. I don't think you will be seeing this type of problem with an
athlon any time soon.


 
Hehe, I hate when Llamas e-mail crap like that. Opinionated message board discussions should stay on the message board! It helps keep people from becoming too much of an idiot, it's good for the guy getting e-mailed, it's good for the bozo wanting to send an e-mail.

Tech questions through e-mail are ok though, although even they can best be served on the message board.

Nesu: I usually ignore e-mails like that, I hope you posted his e-mail to the discussion in question. 🙂
 
Actually, I get a little pissed when people refer to the aging P3. Having been involved with systems development for a long time, it takes much more initial effort to design anything that can scale well and be capable of upgrade. The architecture really doesn't matter much, the proof of this pudding is how well it performs in the real world. In real world terms Pee3's and Athlons perform almost the same.
Higher clock speeds are easier to achive with Athlon/TBIRD but they simply don't scale as well as P3. I'm a great fan of AMD, been using em since 386-40, but I wish they put more into reducing the power consumption, Intel has em beat hands down. I want a CPU not a toaster oven. Yes, I know, Willy will be a hot mutha too.
 
Anybody else notice the fact that he said AMD Athlon supports a 200 micro Hert bus speed? Not very smart.

Hz = Hertz
mHz = micro Hertz
MHz = Mega Hertz
GHz = Giga Hertz

Etc, etc etc...

BTW, I second the power consumption comment. Hot running CPUs are annoying. :|
 
IF you're not for Intel nor Amd than what are ou for Cyrix? That chip SUCKS! IT's at least 50 % slower thatn it's competators.
So be quit and stop posting useless messeges
 
The design behind the Athlon core has been around almost as long as the Pentium. Shortly after the Pentium core came out two new players entered the race leaving AMD with their 486?s. One was Cyrix and the other, I can?t remember the name but someone here may. Anyway the company (not Cyrix) had a core that would smoke a Pentium but lacked one thing, a math coprocessor. The company was not doing to well and after some time AMD bought them out. They then did a little architecture changing and added the math coprocessor?.thus the Athlon.
 
Don't even bother listening to GladiatorMaximus. Only listen to flames from people are are more than Junior Members or Members... 'course, this is kind of a flame and I'm only a member, but I don't act stupid

"but I wish they put more into reducing the power consumption, Intel has em beat hands down"

actually Intel has em beat only barely (have you seen that table that displayed power consumption for nearly all existing CPU's? I'll have to find it for u) when comparing the same mhz.

AMD however has the advantage (Vs the p3), because once they impliment their new core (with all those tweaks), they will reduce power consumption, as well as increase mhz-mhz speed. the P3 has been tweaked to all hell, and still sucks power like nuts. the reason for this is becuase it wasn't designed for this kind of speed, so to get it to run properly, it needs lots of power. AMD's original design needs it too, but it's not even been tweaked yet..
 
RSI,

Man, I'm sorry, and I won't flame you, even though I could, but YOU are wrong about the prefix also.

m is NOT micro.
m IS milli. Micro is represented by the lower case Greek letter MU, which looks like a "u" with a little leg on it.


Like this: µ So, microhertz would be spelled µHz

Someone smart please tell me how they, in the design process, make a design that can run up to a certain frequency? I mean, a xtr is a xtr right? You shrink them, their response time gets faster right?

Or does it involve the layout of the chip, on how they run the traces to minimize noise and crosstalk and all that stuff?

Or is the work done in one cycle too much for the xtr to handle beyond a certain frequency?

Yeah, I'm dumb ... someone please enlighten me ...
 
one word beat pipelining. My understanding is that deeper pipelining helps increase the potential for higher clock speeds.
 
well that table isn't the one I was looking for.. I did a search on it, but I'll look in the Anandtech webnews section..
 
ok I found it after searching Anandtech's webnews..

Tech Report it turns out you are right, the intel chips don't NEED nearly as much power as AMD's chips, however the amount that turns to heat is another question..

what this means is this, AMD needs those tweaks for it's CPU now.. look how well Intel has done by tweaking the P3!

EDIT: DAMN forum changes.. ahh well I guess it helps the newbies! I'm too used to putting the [L] sign for links... hmm.. I figured out how to get around it though..
 
I agree with Soccerman in saying that the Athlon is nowhere near as tweaked as the P3.

I can't wait for AMD to release the 760 chipset so we can once and for all see that the Athlon is clock fo clock faster than the P3. Just compare KT133 benchmarks to those of the Apollo pro's and you'll see. Even the wise one, Anand, pointed this out before.Then we'll all see the dynamic duo (Tbird and Mustang) put the entire Intel production line to shame.
 
Soccerman,

ALL the power turns to heat, where else does it go ?? . Deep pielines do indeed lead to increased clock speed but that generally means that each pipeline stage does less work, hint P4 /hint
 
&quot;ALL the power turns to heat, where else does it go ??&quot; if you run power through a wire, does all the electricity turn to heat? that's a negative. in fact, the better the conductivity, the LESS heat it makes.

if you have a device that uses electricity however, it turns electriciy into some form of energy. (motors turn electricity into physical energy, lights turn it into heat and electromagnetic waves (light), CPU's turn electricity into heat (obviously), and an intangible thing called data, or the ability to process it. Heat is a major byproduct of CPU's, however not ALL 50 watts that goes into a 1ghz CPU comes out as heat.

The Athlon design has not been around since the Pentium days, it is based off of an Amd designed core, not another companys. You are probably thinking of the k6 core which Amd built off of a Nextgen design after they bought them.
