384kb cache on Athlons?

[Ilmater]

This is incorrect, right?

 

[splice]

yes.

128KB L1
256KB L2

They are exclusive cache levels so there is a total of 384KB of cache available.

"Cache: 384KB " Is correct but it's 128 L1 + 256 L2.

Those numbers will be changin in about a week

Chiz

Heh, its been a week, Monday most likely

512KB L2 Barton next week!

This is from AMD's website:
"The AMD Athlon? XP processor with performance-enhancing cache memory features 64K instruction and 64K data cache for a total of 128K L1 cache. 256K of integrated, on-chip L2 cache for a total of 384K full-speed, on-chip cache. "

I think the ad is adding the L1 and the L2 cache to come up with that number.

It's correct for the reasons stated above.

Keep in mind, than Athlon's cache design is different from Intel. Athlon's CPU have data in 1 cache only (L1 or L2) - no duplicates. So AMD cpu's cache 384kb of unique data. Intel's CPUs (IMHO) duplicate data from L2 into L1, so at any given time data from L1 is stored in L2. So Intel's CPU's have as much unique data in cache as L2 cache size.

Is the Barton 512k L2 and 128k L1, or 128k L1 and 384k L2?
I'm guessing 128/512?

You know, I posted this right as I was leaving work today, and on my way to my car, I realized how I'd been so focused on Barton's 512k L2 cache that I forgot completely about the L1 cache. So I get back in here, and 3 people have basically said the same exact thing. Once splice said it, it was pretty much a done deal. Are you just beating a dead horse?

But then, we've got paralazarguer, who apparently just wants to up his post count. WTF?! You know, I should just go in every thread and post, "I agree with what they said," and see if I can hit some kind of honorary diamond membership for most posts in one night.

Well, if you had bothered to go do a small amount of research, you would never have had to ask this question in the first place, so I think the people who live in glass houses... yep. No offense, but the Search button and Google can really surprise a guy sometimes

Imater, it's good to have multiple people respond with the same answer to your question. This way you have *confirmation* and you know that the first response wasn't incorrect.
