Tell me something about AMD CPU

[raylee011]

I went to AMD website already, but I didn't like the way they explain the CPU. So, can someone please tell me something about AMD CPU, the Duron, Althlon, Althlon TB, Althlon XP. The cacah, FSB, etc. Thank You.

 

[girish]

Well, you can always ask for the free technical CD-ROM or download the manuals.

Here is the summary:
<b>Duron:</b>
Interface: SocketA (462 pin)
Core/Codename: Spitfire (upto 1.0 Ghz), Morgan (1.1 GHz and above)
L1 cache: 128k
L2 cache: 64k
FSB: 200 MHz DDR (Alpha EV6 bus)
- A value processor, subset of the Athlon just like Celeron is to PentiumII/III/4

<b>Athlon:</b>
Interface: SlotA (282 pin SEC) for K7/K75 and some thundirbird versions)
SocketA (462 pin) for rest of the line.
Core/Codename: K7/K75(upto 950 Mhz), Thundirbird (800 MHz to 1.4 GHz), Palomino (1.2 GHz and above)
L1 cache: 128k
L2 cache: 256k
FSB: 200 MHz DDR (Alpha EV6 bus)
Introduced to compete with the Intel P-III
<b>AthlonXP:</b>
Interface: SocketA (462 pin)
Core/Codename: Palomino (1.33 GHz and above, uses model numbering to indicate relative P4 performance)
L1 cache: 128k
L2 cache: 256k
FSB: 200 MHz DDR (Alpha EV6 bus)
Competes with P4.

<b>AthlonMP:</b>
Interface: SocketA (462 pin)
Core/Codename: Thundirbird/Palomino
L1 cache: 128k
L2 cache: 256k
FSB: 200 MHz DDR (Alpha EV6 bus)
Capable of Dual SMP, AthlonXP is supposed to be MP capable but isnt officially validated for the operation.

Hope its enough.

Summed it up pretty well.


A few sidenotes.

Right now no one buys a duron, the tbird is nearly always cheaper and faster (for sure if you go one speed bin higher like 1250tbird versus 1200duron).
The xp1600 is the best price/performance cpu right now.
Most socket a motherboards with 133/266fsb can support the athlon xp, but all socket a mobos can run duron/tbird.

yes, but I for one just got a couple of Durons for my new office machines. The 750 MHz chip cost less than half the Tbird 1.1G! The idea was to invest the savings in a better board - I got the Asus A7A266 (but dint get either rev B or C) with PC133 SDRAM (I will OC it to 133 MHz FSB just liek my home machine - 600@800!)

Anyway, I might add that unlike the socket370 platform, socketA is here to stay! The next core Thoroughbred as well as later on Barton will be socketA. Most boards will just need a BIOS update. Thoroughberd in particular that will turn 0.13u will be the most interesting processor since it will run at higehr clock as well as it could be unofficially clocked higher, going by AMD tradition!

dude, let me tell you about AMD cpu's stuff that no one here wants to tell you.

1. AMD cpu run hot, if they don't fry themselves they will usually cause software problems over a period of time and will cause you to buy additional fans, making a very noisy enviroment.

2. AMD has been trying to reduce the fryage(I made new a word!) by going the cheap route and putting 4 little pads on the cpu. now they have the XP PR-/+ 300 you need a special mobo and attachment to keep it from frying.

3. the AMD platform is full of bugs incompatibilities, glitches, errant IRQ's, weekly 4-n-1 driver downloads, bios patches praying, worry, aggravation.

4. to this day I've not heard of a mainboard(retail) that will take advantage of the XP's faux thermal diode.

these points will be debated but, remember this: everytime an AMD user presses the pwr button on their system, they usually say a prayer.

1) It's a known fact that P4's consume more power than Athlons. Intel fans at [H]ardOCP have admitted that the P4 actually runs hotter than any AMD CPU. Oops. :tongue:

2) No you don't, you just need a decent, $10, AMD-approved HSF (or a retail Athlon) and free health-monitor software.

3) Funny, I installed a 3-in-1 only once, and I never had any of these problems. I even have an SB Live!, and I still have none of these problems.

4) Not all that necessary, though it would be nice to have. See #2.

I'm not going to say anything except that AMDMeltdown is an unrespected member of these forums who is irrational and downright liar. I have found that 99.9% of the time AMDMeltdown lies or says half-truths with a twisted meaning.

I still want a link for that.

hey... did we ever find out what the P4 heat spreader was made out of? was it steel or aluminium?

[Negaverse23]

What do you mean by putting 4 little pads on the cpu?

I wish they used copper instead.

Umm, NeGaverse23, since when does AMDMeltdown make any sense? Everything he says is either a lie or complete nonsense.

[lhgpoobaa]

copper too soft (for those with an extremly caviler attitude to the p4's indestructability) and probably too costly.
P4's allready cost a ton.

nice idea though.

[Matisaro]

Poobah, I had compeltely forgot about that discussuion. I heard the heatspreader was steel somewhere, but others heard aluminim, does anyone know for sure?

[lpenix]

Amd has its flaws, and so does intel, you will get the about equal performance with both, just that amd is cheeper. i had the same issues about a year ago when i switched from pentium to athlon, the athlon never let me down, as a matter of fact i just got my 2nd athlon , a 1800+ and that thing rocks.

That only comment and personal opinion.

yeah... thats the thing... soone seems to know...
have u emailed Raystonn yet? he would know.

and i would HOPE it would be aluminium...

and ive been thinking about hammer and such... with tiny 64mm^2 dies, i owuld think that heat spreaders would become manditory (and for the anti moron anti crush feature)

[Kelledin]

It's personal experience from P4 owners--people loyal to the Intel brand name. Otherwise, you would have been justified claiming the opinions were skewed in favor of AMD. If they're skewed at all, they're probably skewed in favor of Intel. :tongue:

[Guest]

I always thought loyalty was a little !@#$%. I'm in for the best performance there is and still have money in my pocket for other things.... Why would I spend more for an Intel and get lower performance than I could with a faster/cheaper AMD? Now if Intel actually put their PIII engineers back to work and produced a good processor like the PIII was and at a good price, you wouldn't see me going to AMD. AMD/Intel aren't what they used to be back in the k6-2/P2 days. Loyalty to one or the other is complete ignorance.

My own article on the issue - <A HREF="http://www.64bits.org/cpuheat/cpuheat3.htm" target="_new">here</A>.

All data is authentic and obtained from the respective datasheets, which are also linked. P4 is documented to consume 72W, but in reality it could be much more, about 105W. I will find the link for you (probably <A HREF="http://www.vanshardware.com" target="_new">http://www.vanshardware.com</A>) that says its about 25% too low than the actual! They say Intel took advantage of superior thermal management built into it, and documented it to be less for two reasons:

1. The competing platform consumes less than half the power, it would be a shame to admit their processor will consume twice as much power and perform about half as much the AMD Athlon!
2. By giving smaller power consumption figures, Heat Sink designers will make smaller and cheaper fans that will make the platform cheaper. they wanted all the people to put money buying P4 rather than the heatsink! And still they will get away with inferior cooling thanks to the better thermal managenet in P4!

Sorry if it looks a troll, but its true! Maybe intel dint intend that but this is how the things stand!!

the four pads are in the four corners on the CPU - used to prevent crushed core syndrome. these pads help reduce the pressure and align the heatsink during installation.
