There are some recent rumours from <A HREF="http://www.amdzone.com" target="_new">AMDZone</A> that T-bred has 512Kb of L2 Cache. Apprarently Compaq have T-bred based notebooks on sale now....<A HREF="http://athome.compaq.com/MiddleFrame.ASP?Page=ShowRoom&..." target="_new">Click</A>, the specfication also clearly states there is 512KB of L2 On chip cache.

Hmm if it went to laptop design, then surely desktop ones would be easier to implement, right? If so, then I do hope Tbreds have 512K L2!! Could really help negate the 533MHZ FSB for P4!

AMD is making 1.4GHz chips for laptops using the T-Bred? Are you sure this is the T-Bred and not just wishful thinking (typo or lying) on the part of Compaq?

Hopefully, the delay is due to the introduction of a 512KB L2 On Chip Cache. If so, I forgive the poor bastards over at AMD.

Raystonn, what do you think about the likelyhood of overclocking the upcoming P4 2.26B (533 MHz) to PC1200 spec. with the current available TI DRCGs and whatever available Samsung RIMMs ?

Which part is most likely going to be the limit ?

Would it be better to take a P4 2.0A and overclock to PC1066 spec. or whatever is possible ?

Well we already know there are +1700 T-breds floating around...<A HREF="http://www.vr-zone.com/Home/news138/news138.htm#2254" target="_new">Click</A>. It doesn't seem that far fetched in thinking AMD are releasing a +1600 mobile T-Bred. Naturally mobile parts will be clocked lower than the desktop versions.

Besides, their Athlon 4 was 1.33GHZ, it would make sense to go upwards for latops too now wouldn't it Ray?
I dunno but Ray's post had little sense...

You can find a pic of the mobile T-bred <A HREF="http://www.vanshardware.com/news/2002/02/020201_PC/0202..." target="_new">here</A> (it uses the new micro-PGA packaging)..as a result it is only 33mm sq compared to the normal desktop package size of 49.5mm sq.

The processor could handle it. The memory and motherboard (DRCGs) would be the questionable parts. This is only a 12.5% overclock and is very questionable at the moment. If the new PC1066-capable motherboards come with a 2X RDRAM multiplier, then overclocking the processor will be no problem. Otherwise, I suggest grabbing a 2.4GHz Pentium 4 on with 400MHz FSB. The higher multiplier makes overclocking of the processor much easier.

The P4 2.20A will be priced as the 2.26B, so which one would you prefer ?

/Copenhagen
April 9, 2002 8:59:19 PM

That depends on what motherboards are available at the time and what they can do. If the chipset can work at high FSB speeds and offer a lower RDRAM multiplier (2X), I might grab a B model. Otherwise, I would grab the A model. If I did not want to overclock at all, I would grab the B model.

Am I the only one that missed the fact that it says "Athlon 4"?

Huh ?!.....AMD have always called thier mobile versions of Athlon XP as 'Athlon 4'. Or have I totally missed the point ??

<font color=purple>Ladies and Gentlemen, its...Hammer Time !</font color=purple>
April 9, 2002 9:22:30 PM

But I wouldn't have thought this would be an 'XP', as it's a new core. Since the Athlon has had 4 cores, it's the Athlon 4. Therefore, the Thoroughbred would be the Athlon 5. Or am I wrong on something here?

April 9, 2002 9:27:37 PM

err..no I think AMD are sticking to Athlon 4.

<font color=purple>Ladies and Gentlemen, its...Hammer Time !</font color=purple>
April 9, 2002 9:59:24 PM

According to Compaq the chip is available in build to order systems NOW and should be available in retail soon (The 725 series is apparently a retail model)

I guess this helps explain some of AMD's seeming delay in shipping (tho this does prove that they did indeed begin Thoroughbred shipments before the end of Q1 as they claimed.)

I wonder how much the addition of another 256KB of L2 cache will improve performance? Any ideas anyone?

i forgot the thread or even who posted it. but i thought i heard someone saying before that the xp/tbred wouldn't gain that much performance wise with 256kb L2 more?

I run duals because i multitask between notepad, outlook express and winamp :lol: 
April 9, 2002 11:41:39 PM

I'd say just about enough to compete Intel's new FSB and RDRAM. But I do hope it's true. Someone should contact Compaq and ask them for any possible typos, if not, then Tbred is indeed something we underestimated!
Besides, add 256K L2, and 333MHZ RAM and FSB, and you got enough juice to compete the new NWs, as well as higher speeds!

The bigger L2 cache will provide some performance boost, but not as much as a 166 FSB would have :frown:

You can't be sure about that.

Burger, I read somewhere(inq I think) that amd may introduce the tbred without any change in titles, and deffinatly for the mobile.

With the die shrink to .13nm, will it be easier (possibly) to get up to 166FSB? Imagine that with 512kb L2 cache...very competative with the Piva.

I have never heard of an athlon which wont do 166fsb when you lower the multi, why is everyone acting like it cant do 166fsb all of a sudden.

Oh. I can't mine to go above 150Mhz FSB. Athlon T-bird at 1.46Ghz right now, multiplier 11 with 133FSB. My motherboard doesn't like anything above 150Mhz I guess. Or is it because the AMD760 chipset limits the max FSB?

Get an IWill XP333 and some good DDR RAM and you can get to 200MHz.

The chip, not mobos and ram, I have never heard of a chip which could not do 166fsb(assuming the mobo can ram could handle it)

Any mention of the size of the L1 cache? I assume it would be 128k.

I'd prefer Abit KR7A or Asus A7V333.

:smile: Good or Bad have no meaning at all, depends on what your point of view is.
April 10, 2002 1:42:07 AM

It is 128k and will remain so.
Intel's cache is different, which explains the small size of 8KB.

no your right.

It's the mobile Athlon XP. check out amd's website. It's just athlon XP. AMD does not have on there site anywhere about a mobile t-bred. They have mentioned the mobile athlon XP however.

These compaq web designers probably don't know the difference between a mobile pentium 4 and a mobile athlon xp.

Not really, but look at how much of a difference it made on the P4. Not a huge amount. The P4 needs the bigger cache more because of the small L1 and higher latency of RDRAM. On the other hand, the data prefetch is better, so it needs it less. But I think I can still confidently say that a FSB increase would help the Athlon more.

I assumed it would change since they moved to numbers (at least it should, IMO). We'll have to wait for the official announcement to know for sure, I guess.

Why not both, theres nothing stopping us computer savvy people from running the 512k tbred at 166.

Skater, Compaq reps have confirmed the chip in question is indeed a Thoroughbred chip

Hey, do you really think i should be able to get the FSB to at least 150 without lowering the multiplier? I have an AXP 1900 on a Soltek SL-7DVRV4 with a dragon orb 3 and good case cooling. The ram is Kingston DDR 266 CL=2.0 ECC(off), and i cant get it past 146.

I have Athlon 1600+ retail, MSI nForce420D, Crucial DDR PC2100. I can't get it past 146 either.

here is proof it is only a .18micron mobile athlon XP

it's at www.anandtech.com or hardocp would have it too probably.

"HardOCP is reporting that the rumours of 512k Athlons are just that. We also have some confirmation from our own Anand Lal Shimpi in our forums:
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. "

If you check the <A HREF="http://www.hardocp.com" target="_new">HardOCP site</A> you will see the following quote:

"Just wanted to say thanks for pointing out something we missed. The laptop is not a Thoroughbred proc. It is a mobile Athlon 4 with 64KB on the L2. It has been fixed. Thanks again.

Adam Gernhart
Compaq.com Quality Assurance, Site Operations, and CEMS Administrator"

Well he obviously doesn't have a clue what he is talking about because the Athlon 4 (.18 mobile palomino) has always had (and still has) 256kB of L2 cache. The proc he must have been referring to would be a Duron. In addition, the reference has NOT been "fixed." I went to the compaq site myself and selected from the menus a 725US (not from the above link), and it still says "512KB L2 cache." I'm not saying that it isn't a typo, just that HardOCP's Compaq contact is not valid, is uninformed or worse, doesn't have a clue.

I thought a thought, but the thought I thought wasn't the thought I thought I had thought.
April 11, 2002 11:54:39 AM

Still ya gotta admit, we woulda really loved 512K L2 for desktop Tbreds!
