L2 cache on Tualatin Celeron

[Racoon]

Does the Tualatin Celeron have a 4-way set associative L2 cache like the old coppermine celerons or a 8-way set like the PIIIs?

It's still 4-Way. More L2 is great but the pipelining is still contricted.

what do you mean by pipelining? i remeber my old 133mhz pentium that had xxxbits of pipeline burst cache (cant remember how much thats why i put xxx). whats up with the pipelining?

You're thinking of something else, but in the ballpark.

4-Way and 8-Way associative just has to do with how data is transferred through the cache.

Take for example:

You have 8 lanes on a highway as opposed to 4. You have the same amount of cars that need to use those highways. Which highway is going to get their drivers from point A to point B the quickest supposing everything else is the same?

I'm fairly sure that it's 8 way. Look at any of the reviews of the tualatin review. Look at how much it distances itself from the Celery 1.1. I doubt that all the performance boost is due to 128 kb and data prefetch logic. :) A quick look at the recent review of the Celery 1.2 at Xbitlabs (http://www.xbitlabs.com/cpu/celeron-1200/) confirms this...I think this point was made in a couple other places as well...

Hi,

I'm quite sure that the new Celeron has 8-way cache, becuase I recently saw a review of the new Celeron. The testers were lucky enough to get an unlocked sample, so that they could bench it @1200 MHz and 133 MHZ FSB, instead of the normal 100 MHz FSB, against a "real" Tualatin P3 1200 with 256KB L2-chache.
The result was, that there was no difference in performance between the Celeron running @1200 MHz 133 MHZ FSB and the P3 1200 MHz 133 MHz FSB!!!

8 way. Looked at data sheets

Lol, if you lived in Milwaukee, the mayor would say the 4 lane one, because when the data became MORE constricted and jammed, it would encourage the data to use city streets.

It's 8 way associative but still has a latency of '1' compared to a latency of '0' for the P3's. I'm curious what these baby's will cost over here in the Netherlands cuz a Tualatin P3 1.2Gig costs about the same a P4 1.8 Gig is!!! And you will need a new mobo for both of them.

Where are you reading this?

My L2 cache can beat up your L2 cache. :D
