Which CPU is faster?? Duron 1100(Overclocked) T-bird 1000(Overclocked)?? any idea?

For most common apps, the T-Bird.

the only difference between the two is that the Duron has 64k of L2 cache while the Tbird has 256k.

for day to day apps, both will perform equally well, but for heavy duty processing like database, compiling, image editing teh Tbird will perform considerably faster.

also depends on the FSB your using.
if they both have a 100Mhz fsb then its pretty much a tie, with the +100mhz difference being canceled out with the increased L2 cache size of the Tbird.

if the Tbird is a C model, then 1000mhz with a 133mhz fsb will significantly overcome the duron in all apart from pure Mhz benchmarks.

i.e. my 1200C oc'ed to 1368 @ 152 easily supasses the 1333 @ 133 and is at least on par with the 1400 @ 133.

The Duron has 128 KBytes L1 cache and 64 KBytes L2 cache.

The Athlon differs form the Duron only in the size of the L2 cache: 256 KBytes

<A HREF="http://www.digit-life.com/articles/overclockingamd/" target="_new">Source</A>


Anyhow, the way it works is that they test the L2 (and L1) cache on newly-produced Tbirds. If they find any bad cache, they mark which half of the cache has the bad spot. Then, later on they disable that half, call it a Duron, and send it out for cheaper.

Durons actually HAVE 256k of L2, just half of it has been disabled because it's slightly bad.

Interesting...anyone know how to turn a Duron into an Athlon?

where did you get that info Fat?
if its true then I am really looking forward to convert my two durons into athlons! and if they mark 3/4th of the cache bad, why do they leave 64k? they could have a 128 cache on duron for free!!!

now if they are produced on the same wafer as that of the tbird, why do they
<b>1.</b> work on lower voltage?
<b>2.</b> consume almost half the tbird power?
<b>3.</b> give different cpu ID strings?
<b>4.</b> and other family and stepping codes?

so they actually make two CPUs and just by running some software on the chip they can make it appear and behave so different?

do they burn in the microcode after the dies are verified? and does this different microcode cause the chip to work on lower voltage and consume lesser power???

then it might be easy to get a duron and get at least 128k cache out of it if not 256k! instead of just 64k!!

Don't have any picture links but the Duron die is smaller than the Athlon die. I doubt there is any hidden cache to unlock.
August 13, 2001 8:02:48 PM

Err FAT?

Hate to break this to you but you are completly wrong. The Duron and t-bird are completely differnt dies. That is why the die of the duron is smaller than the t-bird. So the Duron IS NOT a crippled T-bird, never has never will be.

What you describe is actually what is done with regard to the pentium 3 ala Celeron. The two should not be confused.

Think about it, if what you say is true the t-bird and duron would have exactly the same die size.

A little bit of knowledge is a dangerous thing!

Maybe it's just the cache then, not the whole thing. Someone explained it that way to me, so I can't verify it in any way.

And girish, Durons have 128k of L2. Read my post.

BTW, there's no easy way to un-deactivate the cache :)

Hey Fat,
Not trying to start a flame here but trust me they are completely differnt. The process you describe only applies to p3's and celeron's not to the T-birds. If you doubt me, go back in tom's CPU archives and check. Also, giirsh was right, the duron's have 128k l1 and only 64 k l2. But hey, its a monday and if you go back and edit your post I won't tell anyone :)

Durons have 64k of L2. Read my post.

most likely the tbird (doubt the duron will reach that high... then again i am me...)

if in doubt blame microsoft...
August 14, 2001 2:49:58 PM

what?!
someone gave you bad info man. I've got both here, if I can get my hands on a digital camera or something I'll show you, there is a definate die size difference.
There is no extra L2, unless they add some to increase yields from cache failure.
the Duron has 128K L1 and 64K L2.

so what do you say, 1100 Duron faster than 1000 T-bird???
Fat's opinion carries some "weight"!!!

so what if nobody cares!

Hehehe
My vote goes for the Tbird, hands down. At 1200, the Duron might catch up to a 1000 Tbird, but I still doubt it.

Dammit, you didn't tell me I was taking a test. I would've studied. At least I got it right.
