AMD Zambezi news, info, fans !

[undone]

Charlie D. has written an article on BD shipping(and delays). Pretty interesting read,especially the info on new revision in Q1 2012.

It's odd that they improve performance by releasing newer stepping exclude the factor of frequency increase, there wasn't any precedent like this before, I'll take with a grain of salt.

Either way, it looks like that stepping is the one to keep an eye out for

So, the first shipment (B2 ?) is not the one to keep an eye out for ? Not sounds encouraging ...

Depends on what you are expecting.

If you want to know what BD really is, the next stepping seems to offer the answer according to Charlie.

On the other hand the current BD seems to be competitive but nothing dramaticly better. So if you are looking for an alternative for intel, they seem to to have it at inital launch.


Considering they talk about major integer improvement with a new stepping would indicate their si something amiss now that hinders performance substantially..

[v0dka]

I don't buy the news about new revision with higher integer performance. That would be a TLB sized fiasco.

edit: I also don't get why BD should have just as bad yields as Llano, fact is that the graphics chip on an SOI process is the problem for Llano. Or so I heard.

Bulldozer is in dev since 5-6 years, AMD discovers now, just before the launch, that there are some misses ? I don't buy it ...

[PatRaceTin]

B2 or C0

[jeanjean15]

Always no benchs of Interlagos ?

[duron]

no more Komodo?

oopppssss, this is a Zambezi thread
oh look it's shipping already

But AMD surely didn't have working silicon samples for 5 years. There are multiple steps in developing a processor from ground up and each step (not stepping ) can bring in its own bugs.

So if something is not working (who knows, maybe a feature B depending on feature A and A was not ready until stepping B1...), it may still be disabled and debugged->enabled with a later stepping. It's not about adding features (this is for Piledriver, Steamroller..), but about enabling only the working features. The transistors are there.

Do you remember that Hyperthreading is said to have already been included in Willamette but was not enabled before Northwood came?

Of course he remembers, but he has a selective memory when it comes to Green and Blue, LOL

[Olivon]

To be honest, at this time, i was more green and I never had a P4 processor ...

All I want to see is competition in CPU world, don't mislead dude

Matthias is right but desktop launch is next month and I'm starting to feel worried like many peoples, time is running ...

@JF-AMD do Bulldozer parts have ACP and TDP or will they reach TDP on Turbo?

[JF-AMD]

Charlie D. has written an article on BD shipping(and delays). Pretty interesting read,especially the info on new revision in Q1 2012.

I don't buy that. There are always new steppings, typically every 6 to 9 months. However, new architectures have big increases in performance. Speed bumps are typically 3-5%. That sounds completely backwards.

@JF-AMD do Bulldozer parts have ACP and TDP or will they reach TDP on Turbo?

We will still have both ACP and TDP. With Turbo CORE off, the power will be ACP. Wtih Turbo CORE on, the power will look more like TDP, but will not reach TDP in most cases.

[doompc]

Thanks JF.
And congratulations for shipping the server parts.

[Olivon]

As I mentioned before but has delayed the launch date Zambezi is now fixed (but I have not mentioned the exact date to be seen).

The delay I had with internally because we do not have final silicon, the media samples are still not well defined or something and know that distributors have nothing concrete to pre-order (and other signals that I do not post). This process takes place all in one month and a half off for the launch. So if one of these items are missing is a paper launch with no samples. Incidentally, I still have a few indicators that tell me that something is still not going well.

Mass Production of the final stepping B2G should soon start but it is not yet known and when it is actually available.

Benchmarks indications:
compared 2600K
compared 1100T :S

[informal]

Olivon I have no idea what is that guy saying benchmarks wise. He admits they have no final silicon in hands and then he says the samples they have don't even compare well to 1100T.

The guy is pretty reliable... however his performance remarks are on the indications of B2(F) samples. The other poster just did selective reading and copying posts from him.

Benchmarks zijn met recente B2(F) stepping. Het zijn ook indicaties, echter geloof ik niet in wonderen en zal die laatste stepping niet veel veranderen.

[Dimitriman]

ok that's it. I am definitively settling for an i7 because all these latest benchmarks prove for sure that Bulldozer will be slower than 1100T!

[informal]

Slower than 1100T and will cost from 36%(best case scenario for buyer) to 57% more- 260/300$ for FX8150 vs 190$ for 1100T. Figure out this mystery lol.

No mystery. The price will be lower than that.... I think.

Lower than 260$?? Not what AMD thinks apparently.

7. Prizes:

Top tier prizes: Five (5) AMD FX series eight-core processors. Approximate Retail Value: $300 USD each.

Second tier prizes: One hundred (100) collectible Ruby dolls. Approximate Value: $25 USD each.

This giveaway contest appeared relatively recently. AMD knows the actual performance of FX line and where it can price it.

BTW when Zambezi launches (X8/X6/X4) ,Thubans will go down in price immediately. So even if 8150 is priced somewhat below 260$ ,which I doubt, relative perf/$ ratio will still remain the same. You will have to pay 36+% more for X8 Zambezi to allegedly get approximately the same performance as 1100T and this is what many "sources" with the "ES" are indicating. This is illogical.

[xsecret]

The point 7 might be wrong if AMD got some bad numbers in the final stepping and want to offer a good performance/price ratio...

Anyway, there is something much more interesting in the link you sent. It's located on point 4

I doubt final stepping can do worse than what AMD had with previous steppings(pre B2,the ones that supposedly were slower than X4 Deneb lol). As for point number 4,the ending date was recently changed . IIRC it was somewhere in September (mid September,maybe even 12th). Now is October the 12th. Fits with the recent schedule update on Q4 launch instead of Q3. They may as well do a "formal soft launch" in late September and real availability is mid October.

if the x4 BD costs close to or more than an x6, it should show a very scary sign of how much of a single threaded monster BD will be.
