Duron vs. Athelon

I've heard rumors that Duron's are nothing more than AMD processors that didn't meet the standards to make it an Athelon so they call it a Duron & reduce the price.

Is this true?

No, not really. The way I understand it, Durons are purposely made with less cache (128Kb). This cuts the cost. They also typically work at lower speeds.

AFAIK Celerons are made on the "Fallen Pentium" model where Pentiums with defective cache have half of it disabled and are then sold as Celerons.


Disclaimer: I'm operation on my recollection of old knowledge. I haven't read anything on this topic recently.

Also: Wrong spelling of Athlon.

Im not sure about the current ones, but originally the Durons were only 100MHz while the Athlons were 133MHz also Durons have 1/2 the cache of Athlons.

The older Durons have 64MB L2 cache and 100mhz bus. The newer Durons still have 64MB L2 cache but got a bump in the fsb to 133mhz. Not to mention they got the Palomino based core improvements from 1ghz and higher. Then the die shink to the .13 process later on.

I think you actually mean 64Kb of L2 cache. ;)

formulav8 is correct except for the typo that PorBleemo pointed out.

Just to add a little more information the original duron was the Spitfire core (based on the Thunderbird core) then at 1 GHz it shifted to the Morgan core (based on the Palomino core) both of these Durons where manufactured with 64kb of L2 cache and ran 100 MHz bus.
At 1.4 GHz the Duron moved to the Applebred core (I don't remember if this is based on the thoroughbred or the Barton core) this version actually is a Athlon with some of its cache disabled (to get down to 64 kb of L2 cache) and it runs on a 133 MHz bus.

The Applebreds are Thoroughbred-based. Durons are basically Athlons with some of the L2 cache disabled.

and another bit about dead chips that are marked down, the new Thorton core AMD Processors (266 FSB, Highest Model being the 2400+) are actually Bartons that don't make the cut due to some faulty cache so AMD disables are cache beyond 256K so that AMD doesn't have to make Barton's and Thoroubreds, just Bartons
PS. someone tell me how to properly spell Tho.........whatever
