difference in durons.......

[lepper boy]

I've done some reading in some computer magazines, and they were talking about Durons with like three hundred and something cache... Are they really talking about a duron? or a tbird? or what? the duron I have only has like 64 cache any explanation would be appreciated..

A duron is a "scaled back" version of the Thunderbird Athlon.

The only difference is in the size of the L2 cache. Both have the same general core, the same 128kb of L1 cache divided evenly between Data and Instruction. The Duron has 64k of L2, while the Thunderbird Athlon has 256k

I read that the Duron unlike the celeron wasn't just a t-bird with 192k cache disabled. That it had it's own design. So it aint a scaled down T-Bird. The celeron is a scaled down p3 though.

Not quite. If you want the really nitty gritty, read my article on The Fundamentals of Cache.


Here's the relationship between the Celeron2 and the P3 coppermine: Half of the cache on the P3 is disabled, which cuts associativity in half, and then they make the multiplier higher so that it won't support higher bus speeds quite so easily (read: they try to stick it at 66mhz bus).

When you say that its not a "scaled down" version, you're right. I was careful with my words. I said "scaled back". They are physically different cores. The Thunderbird just has more cache, but both are the same way associative.

They were probably talking about the TBird, since it has 128k L1+256k L2 = 384k of cache.
