Or may be AMD didn't even make a derivate design - FX 4xxx quad should be more a BD 8 core split in half.
Because the 6core FX 6xxx it's clearly just an 8core with 1 module broken.

Yes the 4core would be an Orochi die with 2 deactivated modules, comparable to the the Phenom2 5xx line.
There are several reasons for holding it back:

a) Sales: Too much Phenom2 X4 & X6 inventory, AMD wants to sell it off first.
b) Marketing: Emphasize on the "high-end" 6core and 8core models, the FX4 might influence the image negatively, the prices are already quite "cheap".
c) Optimize ASPs: People who are interested in BD and waiting for it, should buy at least a more expensive FX6 and not a cheap FX4.

I for my part will wait for FX4 ^^ Cheap and I assume easily OCable@5GHz, because there are only 2 modules ;-)
That's enough for me.

I don't know. I'm also confused by there being two 8-core. if this chip has a short life on the market, and they're niche chips already, and both are unlocked, so both overclock the same, and... I just don't get it. MAYBE after respinning 10 times they've found yields are so good to not warrant selling many broken chips.

Would be interesting if they allow you to run one core per module, I imagine that would mean the 8 core could become a very nice quad.

Well that's for sure one of the reasons they're holding back!!

A 1055T for U$S 195 and a 955 for U$S 146, those CPUs have never been as cheap as they are now here in Argentina, every AMD cpu had their prices cut... it seems like they're almost giving them away! I'm sure it's the same all over the world and especially there in the USA. I'm looking forward to october 13th! (or mid october, or whenever they decide to launch these new CPUs). My E7300 + P35-DS3P are quite overdue for a complete upgrade... that mobo is at least 5 years old, it got enough parts upgrades already...

Just because DonanimHaber doesn't tell us the price of the FX4 it doesn't mean it's delayed.. it isn't the most reliable source in the world.

Beginning from your interesting(to say the least) comment up to my comment, the main idea of that mini discussion was why AMD might be pricing its chips at those rates?
One of the reasons might be its performance
Another reason is because of competition, which will lower its prices
And another reason is because they can as CPU die is smaller than x6 thuban. This does not concern end user, but this does concern AMD.
Even if x6 FX is cut down X8, it has lower die size than thuban, thus AMD will not be loosing more money than selling thubans.
We have precedent in this - AMD GPU department pricing their GPUs lower to get back the market share or to sell more GPUs, because they had smaller dies.
Though in this instance Intel 2600K has even smaller die, so I wonder what did AMD put into BD to have a larger die than 2600K(which has integrated GPU). But again we should count transistors of al things as there were some discussions around internets, that BD die has some empty spaces.

---

AMD sets prices after how their chips perform compared to the competition. Not after die size. Production cost isn't part of the pricing. If their chips cost 50$ or 150$ to produce won't change that. Even if they cost 150$ to make they can't put it at 400$ if it performs like a 200$ chip. It wouldn't sell at all. If a chip is to expensive to produce to fit it's price range it will simply not be produced.

Compare with Radeon vs. Geforce. Their pricing reflect performance and functions, not die size. nVidia had lower margins per graphics card as a result. The GTX 280 was extremely expensive to make since it was a large chip, but mainly because of the yields being so bad. But they sold it at the same price level as they sold 8800 GTX at it's time, and cheaper than 8800 Ultra.

Hmm already forgot the now offline listings last week in the online shops? There were only the FX6 and two FX8, not a single FX4. Exactly as DonanimHaber tells now. Therefore, the whole story seems to be pretty accurate to me.

Here ya go....we can vote our speculation now....LOL

It's hard to forget something I've never noticed. Anyway, as you say that list is gone now so I have no idea how accurate it was.

Edit: A bit like saying that there will be only one Interlagos model at launch, because the same site lists only one model:

http://www.shopblt.com/cgi-bin/shop/...er_id=!ORDERID!

Dunno if it has been seen but read this a few minutes ago:
AMD Bulldozer CPUs Launching October 12th w/ Prices Starting at $175

For that low of a price i see a 8150 in my future instead of a 4100

Similar minds think alike :). I'm waiting for the cheap FX4xxx to put it in a cheap AM3+ board and drive it to ~5Ghz on good air cooler. I doubt I will need anything faster than this and with help of new power management and updated K10stat I expect to run it at super low clock and low voltage for the most time (when I don't need that much of compute power). It should be massive step up from my trusty K10 @ 3Ghz which BTW is doing great ,knock on wood.

Not sure it's the best choice for you if 5GHz is your goal. It's most probably the same Orochi die with 2 modules disabled. Usually not because those modules are broken, but that the die has subpar electrical properties, so that with all the modules enabled it wouldn't fit in the 125W TDP class. Hence the realtively high TDP.

EDIT: But, who knows... Perhaps it's still capable of 5GHz, but at a higher voltage, which results in a considerably higher power draw (compared to that if you get an FX 8150 and disable two modules manually or set only the 2-module turbo clock high).

BTW, just heard GloFo is turning most if not all of their 45nm lines to 32nm. Wouldn't think they will do that if BD was such a disappointment...

$146? Thats expensive! I just bought an 955 for $105 2 days ago. New from newegg.

So last time AMD spoke about Zambezi's availability 3 months in anticipation (with the result we all know) but now we would be 3 weeks away from launch without any official word from them.

Doesn't make any sense, at least to me.

That doesnt mean Zambezi is doing great though, thats just progress. No future things from AMD will be made on 45nm, its all moving to 32 and then on lower. They really only need a couple places to stay on 45nm for other customers who still want that, but the majority of their business is from AMD and AMD has moved on to smaller designs all across the board.

Yeah well he is in the Land Of Silver, not USA..

Right, but if Zambezi is such a disappointment as some may think it is, then there would still be a higher demand for Thubans, even Denebs.

Otherways, there were news on Phenom II's going EOL shortly. Only Athlon II's remain a little longer, they say. (I mean AM3's, not those on FM1, made out of Llanos with a disabled IGP.)

mas no geral o Sandy bridge(2600K) é melhor por isso a inesperada redução no preço.

Don't know if you guys know him. But he's a very respectable brazillian enthusiast.

He says "FX8150 is faster than any variation of the preview uarch (faster than any K10) and in some few cases its equal or faster than the i7 2600K. But on avarage it's slower than the 2600K, that's why the price droped to U$244".

he's from Argentina
In Brazil a X4 955 costs you R$280, wich is about ~U$155
very expensive, isn't? :D

I wish we had your prices here! U$S 350 for a 6950 when you guys pay U$S 100 less. That's the way it is down here.. Anyway, there have been noticeable price cuts on AMD's entire CPU line, as someone said a few posts above me, they're probably trying to sell as many PII cpus as they can.. while they iron out any last minute bugs, etc.

So, in some cases it's equal or faster than 2600k but on average slower... that sounds like it's quite close! Nice! Just to think that AMD went from not being competitive at all to being up there with intel's best is nice to hear. Oh well, time'll tell the truth... It's good to hear this, plus movieman's words and the like... And most importantly, what seems to be competitive performance at an attractive price (if what's on the rumor mill turns out to be true in the end). I'll gladly wait a few more weeks...

i sure freakin hope so i7 2600k has been out for almost a year! no wonder there pushing piledriver out soon after... there gonna need that arch update
