Athlon Mobile 4 1600+ w/ 512 L2 cache?

Didn't see this posted anywhere, but got this from AMDZone they have a linky to here. that shows a Compaq Laptop with 512k L2 cache on a Athlon Mobile 4 1600+


EDIT: Circuit City has the same thing.

EDIT 2: Anand responed at bottom of post, 512k cache is false. 🙁 🙁 🙁
 
Huh. Facinating. That's gotta be a T-Bred, but ya gotta wonder, maybe AMD's doing what Intel did with the P6 transition to .13um process. Think about it. The Athlon XP only gets a die shrink, no additional L2 Cache, and no fsb increase (that's what Intel did with Tualatin). The Athlon 4 get's double L2 Cache (just like the P4-M) and who knows, maybe AMD is upping the Athlon 4's fsb to 266 DDR, and then AMD also gives the Athlon MP double L2 Cache along with DP support as well (just like the Tualatin-S), and finally, after a while, AMD gives the Duron the die shrink, but makes it much closer to Athlon XP performance (Just like the Tualeron, except AMD would most likely give the Duron 266fsb with the additional L2 cache). Just a thought.
 
Well it seems plausible, but I only doubt this information because nothing of the sort has been leaked on any site that I've seen.

Athlon4all's analysis sounds possible as well...
 
Update - if you look at the amdzone.com now, it seems that the processor is confirmed to be a t-bred. Wow, I guess Compaq is shipping them out already
 
too bad its got prosavage graphics 🙁

thats a good strategy to differentiate between mobile and server chips and the desktop chips. the first two are higher margin anyway. should help the performance out, but what would be nice is a bigger data path between core and cache.

Dam, beat me to it 🙂

AMDZone also made a phone call to make sure too.
 
I called Compaq tech support about this. 2 different people told me that the 1.4GHz Athlon 4 indeed has 512K of L2 cache. Very interesting stuff indeed. I wonder if they'll be a desktop version...
 
Why would AMD make laptop Tbreds with 512k L2 and leave the desktop parts at 256. 😱 This looks promising if it's true. It could really make some Intel marketing guys eat crow...considering the last Intel "training session" said the Tbred was just a die shrink.
 
I doubt the extra 256k of L2 cache (total of 512k) would boost laptop performance substantially over a 64k L2 cache (i.e. Duron) to make it worthwile.

Agreed. I would rather see AMD integrate a heat spreader or include SOI right away to get the voltages and resultant heat lower. The increase in L2 will probably be even less effective than it was on the P4.
 
Thanks for the info Accord99, looks like Tbred won't have 512K of L2, according to HardOCP:

Well, I just got confirmation on the link I posted about the Thoroughbred laptop earlier, and one of our friends at AMD got back with me about the link to the Compaq laptop we posted, and this is what they had to say:

"I saw the short article and link you posted about a possible Thoroughbred laptop being sold by Compaq. I can assure you that this is not a Thoroughbred based computer, merely a typo error on Compaq's part. Currently the only Athlon 4 processors available come with 256kb of L2 cache. This will remain so even when the Thoroughbred mobile processors do come out. I don't know if you are familiar with AMD's ordering part number system (OPN), but here is the OPN for the Athlon 4 1600+ AHM1600AQQ3B The last 3 in the OPN stands for the L2 cache size = 256kb. All of this is publicly available information on the AMD website. Just look for the Athlon Model 6 Data Sheet.

In addition, there are other reasons why this could not be a Thoroughbred based computer, but I cannot comment on those at this time. I hope this helps clear things up."

I noticed a few places out there even "confirming" the rumor to be true because they had spoken with a Compaq sales person or some such, but this confirms that there isn't a TBred laptop out.... ( yet ) right from the horses mouth.
 
Having held, benchmarked and used the laptop, it does not have anything larger than a 256KB L2 cache 🙂 Confirmed L2 cache size using WCPUID and CCWS2K2' System Information; Windows XP's System Information was used to confirm that it's the same stepping as other Mobile Athlon 4 processors.

Take care,
Anand

Thanks for the info Boss Man!

Did that AMD rep just say his company was having trouble manufacturing/shipping Tbreds or am I reading too much into this...😀


Just stirrin' the pot...shamelessly I might add! 😉
